电气自动化毕业论文英文

随着我国科学技术的不断发展,电气工程及其自动化系统的建设与发展在人们的生活中也有很大的作用。下面是我为大家整理的电气工程及其自动化专业 毕业 论文,供大家参考。

摘要:随着社会的快速发展,科学技术成为了无可替代的第一生产力,在各个领域被普遍使用。我们日常生活对电气工程及其自动化的应用范围越来越广泛,其作用也不断增强。笔者通过各种文献作为参考,就电气工程及其自动化在发展的过程中存在的一系列问题进行简要分析,根据存在实际不同问题,提出相应的解决方案,以便推动电气工程及其自动化技术水平更好地发展。

关键词:电气工程;自动化;问题;解决 措施

经济的快速发展推动着科技的不断进步,电气工程及其自动化在我国虽然被广泛使用,但是与西方发达国家相比它的应用范围还存在一定的局限性。社会生产力的发展要求相应的科学技术与之相呼应,只有如此平衡才能有效地保障经济与技术的同步发展。所以,我国在加大经济建设投入的基础上,也要加强对科技的重视,特别是加强对电气工程及其自动化系统的重视度。从源头解决电气工程及其自动化系统存在的相应问题,为将来电气工程及其自动化技术的发展打下坚实的基础。

1目前电气工程及其自动化技术发展的状况

电气工程及其自动化是科技创新的新型产物,在学科种类划分方面它具有很强的综合性,将工业生产带入到人们的日常生活。通过近几年快速发展,我国在电气工程技术发展方面取得了显著成效,从某种程度上推动了我国电气工程及其自动化技术,加快了先进科学技术生产力的步伐。通过电气工程及其自动化技术在各个领域的广泛应用,我国国民经济总值得到了迅速提高,电气工程及其自动化在现代电气信息领域中占有绝对的主导地位,将所有关于电气信息的工程都囊括在内,例如我国的农业生产、工业发展、国防制造等不同领域。不但促进我国的经济进步及工业发展;而且在很大程度上改变了人们原有的生活方式,加快了人类发展的步伐[1]。

2目前电气工程及其自动化发展存在的相应问题

电气工程对能源的消耗量过大

电气工程在工业生产中的应用是不言而喻的。无论哪个生产环节都离不开电气工程及其自动化技术,是否能合理运用直接影响工业生产的进度。近几年我国的工业发展几乎趋于智能化,在智能化的工业发展过程中,电气设备是其必不可少的基础设施。电气设备及自动化技术的加入不但可以提高工作效率,还能有效地提高产品质量。由于电气设备及自动化技术的应用,增加了能量的消耗,随着电气设备的不断增加所要消耗的能量也在逐渐上升。目前我国大力倡导节能减排的工业生产策略,很大一部分因素源于能源紧缺现象,因此电气工程及其自动化对能源的消耗量过大,有悖于我国的可持续发展策略[2]。

电气工程质量达不到国家要求标准

对于电气工程的生产过程,人们对其的质量关注度逐渐增强,电气工程的质量对电气工程的寿命起到瓶颈制约作用,同时,对其生产过程的操作安全有着千丝万缕的关联。对于一些电气工程在生产使用过程中,因对相应质量管理部门的重视度不够,再加上他们自身 安全知识 的匮乏,由此便形成了只观察表面结构,而没有专业部门及系统的操作方式,进行监管整个生产施工过程,质量管理工作就很难开展。如果保障不了工程的质量,那么关于工程管理、施工质量等一系列问题都无从谈起。所以电气工程质量达不到国家要求标准,给工程质量带来的危害将无法估量。

电气自动化系统集成化程度不高

在电气工程及其自动化的不断发展及进步的过程中,电气工程及其自动化的发展步入了向集成发展的新高度,对于电气工程的集成化发展将会成为其发展的核心方向。我国对于电气工程及其自动化系统集成化的应用较晚,所以 经验 不足,水平较低,还没有达到系统与系统或系统与功能的有效连接,在一定程度无法完成资源共享,阻碍了电气工程及其自动化的有效发展。

在电气工程及其自动化系统中网络结构不统一

科学合理的电气工程及其自动化系统是电气工程发展的最终目标,目前我国的电气工程企业普遍存在网络架构不统一的现象,由此产生形态各异的电气工程架构,对电气工程及其自动化系统的发展产生严重影响。与此同时,因电气工程及其自动化系统没有对应结构,导致企业间的电气设备及技术无法进行交换使用,一些拥有共性的资源及数据不能共享,无法将电气工程及其自动化技术发挥到极致。

3电气工程及其自动化技术存在问题的相应措施

强化电气工程及其自动化的节能设计

为节约紧缺的能源资源,在电气工程设计工作中,加强对节能设计的研发。在实际的生产及工作的过程中将能源的消耗降到最低,可将供电变压器的绕阻值减到最小,进而减少资源不必要的损失,进而节约能源,将电气工程推上一个崭新局面。

加强对电气工程及其自动化系统的管理

加强质量管理同时认清质量管理的重要性,要普遍对生产员工进行相应知识体系的培训,无论是在技术上,还是在理念上都要进行不断地加强,将施工人员各方面的素质都进行提高。在整个施工过程中,运用科学技术及前人 总结 的 方法 经验对施工材料进行检验及管理,确保所应用的材料质量达到相应的要求。与此同时加强对施工过程的监管,确保整个施工过程科学合理,还要根据实际情况安排施工进度,确保电气工程施工质量的高效运行[3]。

加强电气工程及其自动化系统统一的进程

电气工程及其自动化发展的过程,也是其改进的过程,通过不断地完善,将电气工程及其自动化系统逐步朝着统一的方向发展。因我国在电气工程及其自动化系统的发展起步较晚,经验不足。电气工程企业可以引进关于电气的先进技术及管理经验,对于电气自动化系统的运行可以采用统一的编程设计,达到电气工程及其自动化设备满足不同企业且可以共同使用,充分利用信息资源,达到资源共享的目的,进而推动电气工程在各个领域的广泛应用。

4结语

电气工程及其自动化的应用范围不断被增加,其完善的程度越高对社会的推动力就越大,所以电气工程及其自动化的发展是当前的首要任务。在电气工程企业只有科学、合理、统一的自动化系统,才能保障我国经济的稳步增长。

1前言

伴随时代发展社会不断进步,人们生活生产中电气自动化被广泛普及应用,变成现如今促进国民经济发展的有力手段。电气工程自动化属于一类综合性学科,不单包括机电和计算机相关技术内容,还包括网络控制和机电一体化等相关技术。从电气工程角度出发,作为各类生产活动可持续发展前提保障,其正常运行和创新发展意义是十分深远的,另外它对于工业行业健康稳定前行也具有不可替代的重要意义。值得一提的是,现如今电气工程自动化过程中还是有一定问题存在的,如果未能及时解决此类问题,那么所遗留的历史问题将会对国民经济及电力事业发展造成致命打击。本文对当前电气工程自动化存在主要问题予以分析,同时提出针对性解决对策,希望能够为相关人员提供一些参考。

2电气工程及其自动化中存在的问题

(1)缺少统一系统网络架构。构建科学有效自动化电气工程系统是自动化建设必然发展趋势,但是目前众多相关企业当中,因为缺乏统一系统网络构架,容易造成众多企业拥有不同网络架构,限制电气自动化进一步发展。另外因为系统缺少兼容性,造成企业软硬件交替途中,因为接口众多使得信息数据达不到共享标准,自动化电气系统效能未能得以全部发挥出来。

(2)能源不必要消耗的问题。工业发展阶段,电气工程可以说是占有不可替代重要地位,而电气工程自动化相关技术对于整个工业生产都有着决定性作用,渐渐变成如今工业生产科学合理运行前提保障[1]。尤其伴随智能化工业生产水平日益提升,各类先进设备也被引进工业生产当中,不但使工业生产总体工作效率大幅度提升,对工业行业未来发展还具有一定预见作用。但是目前工业生产过程中在应用电气工程自动化技术时,还有能源不必要浪费等严重问题存在,不单对全球能源紧缺局面造成更为消极影响,对节能减排愿景达成也没有好处。

(3)质量不达标问题。最近几年,伴随物质精神水平逐渐提升,人类安全意识也明显提升,电气工程建设阶段,人们在电气工程服务质量方面也提出更高要求,可以说电气工程服务质量和电气工程使用寿命二者间是具有平行发展关系的,同时和安全使用也不无关系。但是如今绝大多数电气工程在施工期,因为对建设质量疏于管理,同时缺乏必要安全意识,造成最终过度关注检测结构,但是质量监管体系不够完善的不利景象,造成质量管理只停留在表面,不单施工管理无序,具体施工时还不能对质量严格控制,电气工程建设质量不达标,工程建设受到很大制约。

3电气工程及其自动化中问题解决措施

(1)构建自动化系统体系。凭借电气工程自动化进程中主要问题的分析,不难发现电气工程自动化受环境因素影响很大,所以应当采取相应对策帮助自动化系统不断得以完善,充分应用当前所拥有先进科学技术,促进管理目标有效达成。在设备启动和日常运行不同方面,都要力求构建高效工作及管理模式,积极吸收先进管理及设计理念,最大程度对系统进行开发利用,同时使相关成本费用减至最低[2]。构建自动化系统体系能够推动电气工程事业科学合理发展下去,让不同系统为不同生产需求提供服务,使电气工程自动化系统能够独立作业。

(2)节能减排建设。进行节能减排设计时,其中非常重要的设计环节便是设计要建立在实际能源消耗基础上,还要尽可能减少不必要能源损耗,确保电厂整体经济效益提高。打个比方,选取电厂中变压器时,尽量选小阻值的,使变压器能源损耗量减下来,就能直接把运行成本降下来,达到节省能耗的目的,科学控制变压器运行成本。能使用自然光资源时,绝不使用照明设备,尽可能选择那些高效使用年限长设备,坚持贯彻节能减排原则。要不断对电气工程节能举措进行优化,电气工程整个设计阶段,节能思想都是贯彻始终的,所以要对节能设计实时进行优化。在基本需要得以保障前提下,结合先进技术设备将能源损耗降至最低,满足节能减排发展对策,另外对促进电气工程长足发展也具有深远历史意义。

(3)对网络结构充分应用。电气工程自动化阶段,网络结构其功能与结构对于整个系统运行具有直接影响,本文这里所说网络结构能与不同管理系统存储数据自由交换,从而达到提高 系统安全 性与高效性目的,同时这也为网络结构最为重要功能与价值体现。除此以外还要把电气工程自动化有机融合到 其它 领域与行业当中,加强对技术系统和生产设备监管。原因是通用网络系统要在处理完不同数据信息后对相关资源配置情况予以贯彻落实,所以在对自动化系统进行统筹管理过程中扮演着不可替代的重要角色,可以快速安全传输数据信息,让网络结构真正实现互通互联效果。

(4)综合提高管理水平与质量。电厂管理人员要充分了解电气工程自动化的重要性,从而为工程建设质量监管保驾护航,为此要综合提高相关管理人员业务能力及素质水平。打个比方,电厂可定期组织对相关工作人员进行培训,吸纳素质高能力强的管理人才加入,通过这种方式提高管理团队科学建设效率,多从那些成功企业中学习先进管理经验,取他人之长补己之短,更好为电气工程自动化建设打好坚实铺垫[3]。除此以外,要加强建筑材料管理,通过这种方式由基础与源头保障电气工程质量。要明确相关材料来源,以使所选设备满足实际发展所需,材料防潮工作应积极做好,尽可能杜绝材料损坏,要加强防火处理,定期派遣专业人员落实质量监管工作。

4结语

综上所述,窥一斑而见全豹,电气工程自动化不单对电力企业收益有很大影响,与国民经济和人们工作生活也有重大关联。面对该状况,国家和相关企事业单位应当由实际情况出发,不断进行人才充备同时对相关制度予以完善和创新,除此以外,要积极鼓励那些专业人士加入进来,共同为我国电气自动化事业可持续发展添砖加瓦。

关键词:电气工程;自动化;发展

前言

现代工业发展所带来的是社会的全面进步,全世界范围内看,其重要标志便是电气自动化,而从另一个层面讲,电气自动化也标志了科学技术的进步以及发展。这种生产方式避免了很多安全事故的发生,具有现实意义。

一、电气工程及其自动化概述

作为现代化工业发展中的领头企业,电气工程及其自动化正随着时代的变迁不断地更新和发展着。电气工程及其自动化是电气信息领域的新兴学科,是高新技术产业的重要组成部分。由于人们日常生活以及工业生产与其密不可分的关系,电气工程及其自动化被广泛的应用于工农业以及国防等方面,并且在国民经济中发挥着越来越重要的作用。电气工程及其自动化是综合性很强的一门学科,涉及到很广泛的领域,内容相当的丰富。电气工程主要包括电力电子技术,计算机技术,电机电器技术信息以及网络控制技术和机电一体化技术的应用等。强弱电结合、机电结合以及软硬件结合是电气工程及其自动化具有的主要特点。随着科技的不断发展,电气工程及其自动化的技术也逐渐形成了独立的系统。

二、电气工程及其自动化发展问题

1、有关电气工程质量管理的问题

据电气工程行业的相关调查报道称,国内很多电气企业和部门在电气生产管理上存在很大弊端,他们过分关心的是产品的质量检验,而对电气工程质量管理的监测却很不到位。尤其体现在设计单位和建设单位之间缺少必要的交流,这使得产品在设计和施工阶段不能很好的对接而造成不必要的损失;在员工的后期培训管理中也缺乏一定的 教育 和说明,使得培训管理形同虚设;在建筑工程的前期和中期,生产部门和企业之间不能主动加入电气工程的施工当中,只是过多的要求施工后期的工程质量,而缺少对施工质量管理的严格把关,这样就造成了电气工程整体工作的混乱无序和工程质量达不到预定目标,这使得电气工程的正常运转和安全质量受到了严重的影响,因此,面对电气工程中存在的种种管理问题,我们必须采取必要的解决措施予以有效应对。

2、实际需要,而导致的成本增加

在电气自动化方面,由于我国对于目前的电气工程以及自动化系统没有完全的正对性,往往是根据工程的实际需要,依据已有的技术成果而展开设计,在无形中增加了成本。在我国对于电气工程以及自动化的设计、运行上没有比较前卫的程序,在开发的过程中,也无形的拖延了时间以及成本,这些因素都能增加成本的开支。

3、使用中数据传输的问题

虽然从商业时代的脚步上来说,电气工程及其自动化的用途非常的广泛。但是在重要的数据传输过程中却存在着严重的不足。因为数据传输要求的是高精度,搞准确性,并且还得保证其安全性。但是从目前电气工程以及自动化的使用过程来看,信息的交换与程序接口的设计是有着密切联系的。由于不同的商家生产的产品不同,在设计上以及接口的处理上都有着差异化,这使得在电气工程以及自动化数据的传输上得不到安全的保障,有丢失数据的可能。众所周知,安全对于商业信息化时代也是非常得重要,电气工程及其自动化要实现通信安全功能,必须解决数据传输过程中的一些危险问题,才能最大化实现商业信息传输的安全。

三、电气工程及其自动化发展对策

1、有效节约成本

经济市场要求的是高效率、高性价比,市场的竞争促使了每个行业都在寻找能够令企业效益最大化的有效途径,如何才能以最少的投入获得最大的收益,增加营利,在激烈的竞争环境中立足不倒,这是企业人必须考虑的问题。因此很多厂家开始将目光转向更加便捷可靠高效的PC控制技术,很多生产厂家在其日常的生产经营中,通过应用不同层次的电气自动化设备降低了维修操作的难度,同时提高了可靠性和生产效率,有效缩短了产品的生产周期以及新产品的研发周期,并对产品质量有着很大的促进作用。在现代工业环境要求下,工业PC机将会逐步的替代IPC成为工业控制系统的基础设备,这会大大降低工业电气自动化的技术成本。

2、重视数字化技术

电气工程自动化与信息技术结合在一起的典型方式就是数字化技术。这项技术主要是自动化的网络程序,将大量的、多样化的、复杂的信息和企业生产相关的数据指令信息结合在一起编写程序,放入计算机中与网络相结合。未来发展电气工程自动化就必须重视数字化技术的发展,很好地将口令与信息完美结合。

3、建立电气工程及其自动化的通用网络系统

建立电气工程及其自动化的通用网络系统可以优化资源配置,使商业之间的信息交流得到准确性和安全性的保证。一个企业包括设备控制、技术监管、 企业管理 等许多步骤,要想使这些步骤得到资源的合理化配置,就要使这些系统通过网络联系起来,通过建立电气工程及其自动化的通用网络系统,使各个系统之间的数据得到高效、快捷的交换,促使整个企业的优化发展。

4、加强电气工程质量管理力度

电气工程的质量管理问题是人为因素可以制约的,这主要就取决于管理者的管理手段和力度是否到位。首先,要培养专业的电气工程人才。在引进新员工时一定要严格筛选,并进行系统的专业技能培训和考核,对于考核不能通过的可以予以一对一培训,争取让所有员工都能参与到提升自身综合素质打造扎实专业技能的行列中来,为电气工程的建设提供必要的保证。其次,作为管理者也应该对电气工程质量管理严格把关,充分重视,无论是电气工程的专业性、材料质量、管理方法等都是应该重视的方面。

5、实现电气工程及自动化系统的开放化

开放化则是要与外界建立一个接口,实现与外界网络的连接。计算网络是实现信息实时交换和共享的重要基础设施,也是实现管理、决策、设计、控制和制造一体化的关键,它已广泛应用于电力系统各元件和局部系统的管理、监视、调节和控制上,是电力系统信息管理、远动技术、调度自动化等方面的核心。

6、数据传输接口要标准化

建立标准化的数据传输接口是保证电气工程及其自动化系统安全、快捷高效的数据传输的必然因素。由于来自各方面的原因,技术上以及系统设计上存在着一些差距与缺陷,使得我国的电气工程及其自动化跟不上发展的脚步,因此,从事电气工程及其自动化的相关工作人员一定要利用已有的科学技术以及借鉴国外先进的科学成果,尽量实现接口的最优化,从而实现程序接口在使用过程中能够完美对接,减少工程开发的费用与时间。

结束语

电气工程及其自动化技术在现代工业中的地位不断的提升,而在电子信息技术日新月异的发展中,并且伴随着人们对生活质量要求的不断增高,社会的不断进步,电气工程的技术人员也面临着巨大的挑战,在迎接电气工程及其自动化技术的一次次里程碑式的改变过程中,会遇到种种阻碍电气人员前进步伐的困难,因此,只有更加注重自动化的水平,更加注重工程的质量管理措施,和更加注重科技的创新,才能够促进电气工程及其自动化技术的发展,使得该技术能够实现自身的跨越式发展,努力使之成为我国社会主义现代工业化建设的有力保障。

SpainAbsiract - In this paper, a novel controller for parallelconnectedonline-UPS inverters without control wireinterconnections is presented. The wireless control technique isbased on the well-known droop method, which consists inintroducing P-oand Q-V schemes into the inverters, in order toshare properly the power drawn to the loads. The droop methodhas been widely used in applications of load sharing betweendifferent parallel-connected inverters. However, this methodhas several drawbacks that limited its application, such as atrade-off between output-voltage regulation and power sharingaccuracy, slow transient response, and frequency and phasedeviation. This last disadvantage makes impracticable themethod in online-UPS systems, since in this case every modulemust be in phase with the utility ac mains. To overcome theselimitations, we propose a novel control scheme, endowing to theparalleled-UPS system a proper transient response, strictlyfrequency and phase synchronization with the ac mains, andexcellent power sharing. Simulation and experimental resultsare reported confirming the validity of the proposed . INTRODUCTIONThe parallel operation of distributed Uninterruptible PowerSupplies (UPS) is presented as a suitable solution to supplycritical and sensitive loads, when high reliability and poweravailability are required. In the last years, many controlschemes for parallel-connected inverters has been raised,which are derived from parallel-schemes of dc-dc converters[I], such as the master-slave control [2], or the democraticcontrol [3]. In contrast, novel control schemes have beenappeared recently, such as the chain-structure control [4], orthe distributed control [ 5 ] . However, all these schemes needcontrol interconnections between modules and, hence, thereliability of the system is reduced since they can be a sourceof noise and failures. Moreover, these communication wireslimited the physical situation ofthe modules [6].In this sense, several control techniques has been proposedwithout control interconnections, such as the droop this method, the control loop achieves good power sharingmaking tight adjustments over the output voltage frequencyand amplitude of the inverter, with the objective tocompensate the active and reactive power unbalances [7].This concept is derived from the power system theory, inwhich the frequency of a generator drops when the powerdrawn to the utility line increases [8].0-7803-7906-3/03/$ 02003 IEEE. 1637However, this control approach has an inherent trade-offbetween voltage regulation and power sharing. In addition,this method exhibits slow dynamic-response, since it requireslow-pass filters to calculate the average value of the activeand reactive power. Hence, the stability and the dynamics ofthe whole system are hardly influenced by the characteristicsof these filters and by the value of the droop coefficients,which are bounded by the maximum allowed deviations ofthe output voltage amplitude and , when active power increases, the droopcharacteristic causes a frequency deviation from the nominalvalue and, consequently, it results in a variable phasedifference between the mains and the inverter output fact can be a problem when the bypass switch mustconnect the utility line directly to the critical bus in stead ofits phase difference. In [9], two possibilities are presented inorder to achieve phase synchronization for parallel lineinteractiveUPS systems. The first one is to locate a particularmodule near the bypass switch, which must to synchronizethe output voltage to the mains while supporting overloadcondition before switch on. The second possibility is to waitfor the instant when phase matching is produced to connectthe , the mentioned two folds cannot be applied to aparallel online-UPS system, since maximum transfer timeought to be less than a % of line period, and all the modulesmust be always synchronized with the mains when it ispresent. Hence, the modules should be prepared to transferdirectly the energy from the mains to the critical bus in caseof overload or failure [lo].In our previous works [11][12], we proposed differentcontrol schemes to overcome several limitations of theconventional droop method. However, these controllers bythemselves are inappropriate to apply to a parallel online-UPS system. In this paper, a novel wireless control scheme isproposed to parallel different online UPS modules with highperformance and restricted requirements. The controllerprovides: 1) proper transient response; 2) power sharingaccuracy; 3) stable frequency operation; and 4) good phasematching between the output-voltage and the utility , this new approach is especially suitable for paralleled-UPS systems with true redundancy, high reliability andpower availability. Simulation and experimental results arereported, confirming the validity of this control . 1. Equivalenl cimuif ofan invener connecled 10 a bust"Fig. 2. P-odraop . REVlEW OF THE CONVENTIONAL DROOP METHODFig. 1 shows the equivalent circuit of an inverter connectedto a common bus through coupled impedance. When thisimpedance is inductive, the active and reactive powers drawnto the load can be expressed asEVcosQ - V2 Q=where Xis the output reactance of an inverter; Q is the phaseangle between the output voltage of the inverter and thevoltage of the common bus; E and V are the amplitude of theoutput voltage of the inverter and the bus voltage, the above equations it can be derived that the activepower P is predominately dependent on the power angle Q,while the reactive power Q mostly depends on the outputvoltageamplitude. Consequently, most of wireless-control ofparalleled-inverters uses the conventional droop method,which introduces the following droops in the amplitude Eand the frequency U of the inverter output voltageu = w -mP (3)E = E ' - n Q , (4)being W* and E' the output voltage frequency and amplitudeat no load, respectively; m and n are the droop coefficientsfor the frequency and amplitude, , a coupled inductance is needed between theinverter output and the critical bus that fixes the outputimpedance, in order to ensure a proper power flow. However,it is bulky and increase:; the size and the cost of the UPSmodules. In addition, tho output voltage is highly distortedwhen supplying nonlinezr loads since the output impedanceis a pure is well known that if droop coefficients are increased,then good power sharing is achieved at the expense ofdegrading the voltage regulation (see Fig. 2).The inherent trade-off of this scheme restricts thementioned coefficients, which can be a serious limitation interms of transient response, power sharing accuracy, andsystem the other hand, lo carry out the droop functions,expressed by (3) and (4), it is necessary to calculate theaverage value over one line-cycle of the output active andreactive instantaneous power. This can be implemented bymeans of low pass filters with a smaller bandwidth than thatof the closed-loop inverter. Consequently, the powercalculation filters and droop coefficients determine, to a largeextent, the dynamics and the stability of the paralleledinvertersystem [ conclusion, the droop method has several intrinsicproblems to be applied a wireless paralleled-system ofonline UPS, which can he summed-up as follows:Static trade-off between the output-voltage regulation(frequency and amplitude) and the power-sharingaccuracy (active an4d reactive).2) Limited transient response. The system dynamicsdepends on the power-calculation filter characteristics,the droop coefficients, and the output of ac mains synchronization. The frequency andphase deviations, due to the frequency droop, makeimpracticable this method to a parallel-connectedonline UPS system, in which every UPS should becontinuously synchronized to the public ac )3)111. PROPOSED CONTROL FOR PARALLEL ONLINE UPSINVERTERSIn this work, we will try to overcome the above limitationsand to synthesize a novel control strategy withoutcommunication wires that could be appropriate to highperformanceparalleled industrial UPS. The objective is toconnect online UPS inverters in parallel without usingcontrol interconnections. This kind of systems, also namedinverter-preferred, should be continuously synchronized tothe utility line. When an overload or an inverter failureoccurs, a static bypass switch may connect the input line tothe load, bypassing the inve:rter [14][15].Fig. 3 shows the general diagram of a distributed onlineUPS system. This system consists of two buses: the utilitybus, which is connected lo the public ac mains; and thesecure bus, connected to the distributed critical loads. Theinterface between these buses is based on a number of onlineUPS modules connected in parallel, which providescontinuously power to the: loads [16]. The UPS modulesinclude a rectifier, a set of batteries, an inverter, and a staticbypass ac mainsutility busI I Ij distributed loads !Fig. 3. Online distributed UPS /I 4(4Fig. 4. Operation modes of an online UPS.(a) Normal operation. (b) Bypass operation. (c) Mains failureThe main operation modes of a distributed online UPS1) Normal operation: The power flows to the load, fromthe utility through the distributed UPS ) Mains failure: When the public ac mains fails, theUPS inverters supply the power to the loads, from thebatteries, without operation: When an overload situation occurs,the bypass switch must connect the critical busdirectly to the ac mains, in order to guarantee thecontinuous supply of the loads, avoiding the damageof the UPS this reason, the output-voltage waveform should besynchronized to the mains, when this last is are listed below (see Fig. 5):3)Nevertheless, as we state before, the conventional droopmethod can not satisfy the need for synchronization with theutility, due to the frequency variation of the inverters, whichprovokes a phase obtain the required performance, we present a transientP-w droop without frequency-deviation in steady-state,proposed previously by OUT in [ 111w=o -mP (5)where is the active power signal without the dccomponent,which is done by. -I t -1sP= p ,( s + t - ' ) ( s + o , )being zthe time constant of the transient droop transient droop function ensures a stable frequencyregulation under steady-state conditions, and 'at the sametime, achieves active power balance by adjusting thefrequency of the modules during a load transient. Besides, toadjust the phase of the modules we propose an additionalsynchronizing loop, yieldingo=w'-m%k,A$, (7)where A$ is the phase difference between the inverter and themains; and k, is the proportional constant of the frequencyadjust. The steady-state frequency reference w* can beobtained by measuring the utility line second term of the previous equality trends to zero insteady state, leading tow = w' - k4($ -@'), (8)being $and $* the phase angles of the output voltage inverterand the utility mains, into account that w = d $ / d t , we can obtain thenext differential equation, which is stable fork, positived$ *dt dt- + km$ = - + k,$' . (9)Thus, when phase difference increases, frequency willdecrease slightly and, hence, all :he UPS modules will besynchronized with the utility, while sharing the power drawnto the .

Block diagram of the proposed a band-pass filter. In a similar way, the averagereactive power is obtained, hut in this case the output-voltagemust be delayed 90 degrees, and using a low-pass order to adjust the output voltage frequency, equation(7) is implemented, which corresponds to the frequencymains drooped by two transient-terms: the transient activepower signal term; and the phase difference term, whichis added in order to synchronize the output voltage with theac mains, in a phase-locked loop (PLL) fashion. The outputvoltageamplitude is regulated by using the conventionaldroop method (4).Finally, the physical coupled inductance can be avoided byusing a virtual inductor [17]. This concept consists inemulated an inductance behavior, by drooping the outputvoltage proportionally to the time derivative of the outputcurrent. However, when supplying nonlinear loads, the highordercurrent-harmonics can increase too much the outputvoltageTHD. This can be easily solved by using a high-passfilter instead of a pure-derivative term of the output current,which is useful to share linear and nonlinear loads [I 1][12].Furthermore, the proper design of this output inductance canreduce, to a large extent, the unbalance line-impedanceimpact over the power sharing . SIMULATION AND EXPERIMENTARELS ULTSThe proposed control scheme, (4) and (7), was simulatedwith the parameters listed in Table 1 and the scheme shownin Fig. 6, for a two paralleled inverters system. Thecoefficients m, n, T, and kv were chosen to ensure stability,proper transient response and good phase matching.

CONCLUSIONSIn this paper, a novel load-sharing controller for parallelconnectedonline UPS systems, was proposed. The controlleris based on the droop method, which avoids the use ofcontrol interconnections. In a sharp contrast with theconventional droop method, the controller presented is ableto keep the output-voltage frequency and phase strictlysynchronized with the utility ac mains, while maintaininggood load sharing for linear and nonlinear loads. This fact letus to extend the droop method to paralleled online the other hand, the proposed controller emulates aspecial kind of impedance, avoiding the use of a physicalcoupled inductance. results reported here show theeffectiveness of the proposed approach.

电气工程:1Electrical Engineering My decision to pursue graduate study in the United States is underscored by my desire to be a part of the graduate program at your institution. Purdue University offers the flexibility needed for such a vast and rapidly changing field. The research facilities and the faculty at the university are par excellent. Communications is an industry that has changed our lives. In a very short period it has changed the way we have looked at things since centuries. It is one industry that is going to shape our future for centuries to come. Hence my desire to do masters in electrical engineering with communications as my major. My interest in electronics blossomed during my high school years. It was the time when technology had begun to make an impact on the lives of people in India. Hence engineering with electronics as my major was the first choice for my undergraduate studies. Right since the beginning of my undergraduate study electronics is a subject that has fascinated me with its power of applications. The subjects that I have studied include Linear Electronics, Digital Electronics. These laid the foundation for my courses in Electronic Communication & Communication Systems at a later stage. My undergraduate studies already focus on the communications aspect of electronics. A masters degree in electrical engineering with communications as major field is the next logical step. For the past four months I have been working as a project trainee at the Indian Institute for Advanced Electronics. I am working on the design and development of a "PC Controlled Digital Serial Data Generator". This short stint has given me invaluable practical experience. It has given me the confidence to pursue a masters degree and also kindled a desire to do research. During the course of my work at IIAE, I have come across several scientists. Most of them work in different areas of communications. Interactions with them have made me realize the vastness and the scope of communications. My discussions with them convinced me that specializing in communications will suit me very well. The subject of research which interests me very much is spread spectrum communication systems. Coding theory and combinations is another research subject which arouses my curiosity. The subject Communication Theory which I am studying at present introduces these topics in theory. I am eager to find out more about the applications of coding theory to spread spectrum communication systems. In addition I have been a student member of the IEEE (Institute of Electrical and Electronics Engineers, Inc.) for the past three years. Through its workshops/seminars and publications like the 'The Spectrum' it has exposed me to a lot of emerging technologies in the field of communications. It is a strong belief in my family that the American education system has the best to offer in the whole world. This belief arises out of the experience that my parents had when they did their Masters of Science in the University of Pennsylvania during the years 1967-69. If I can get an opportunity to be a part of that intellectually stimulating environment, I am sure my talents will be put to optimal use. India is a developing country with an enormous potential in the information technology business. To serve the needs of this developing industry and more important its vast population, communications is going to become of utmost importance. Thus conditions here are very conducive to supplement my aspirations when I return after completing my graduate studies. 2Electrical Engineering As a graduate student, I will undertake research and coursework in Electrical Engineering to enhance my competencies in this field. I intend to complete my master's degree in order to pursue my doctorate. The research that I am most interested in pursuing at Northeastern University surrounds the optical properties of MEMS devices, and the development of substrate-based fast electro-optical interfaces. My interest in this area stems from my undergraduate study in MEMs development for tri-axial accelerometers. Engineering has been a key interest of mine since childhood. While still in grade school I enjoyed listening to my father, an electrical engineer, teach me about advances in technology, and was always eager to hear more. I was introduced to my first computer at the age of five, and have loved interacting with them ever since. My decision to study engineering as a career was no surprise to those who knew me. In college I found that I was always studying something I enjoyed. I believe it is because I enjoy my life and my work that I have been successful. Spending hours in the laboratory is not something that I dread, but instead I take pride in my work and its successful completion. One example of this that is still fresh in my mind is the successful design of a fully functional microprocessor in the Xilinx environment. All told, the project took over 150 hours of each design-team member's time. However, I did not look on it as a drain, but an experience for learning and a focus for my professional and technical development. When we finished the project we felt the sense of worth and pride in completion of a task that was once above our level of knowledge. Pursuing a graduate degree in the research field I have chosen also feels like a challenge, and I know that study will frustrate me at times. However, I feel that my commitment to learning will not be swayed. I feel confident in my ability to be creative in my perspective, and to persevere. My ultimate goal is to be an innovator in the field I have chosen to study. Professionalism and creativity are my most valued strengths. At the heart of my interest is the advancement of man in concert with his environment. My personal philosophy of life will matter greatly during my study and after its completion. That is why I devote time to reflection on my goals and their implications. Money has never been a motivator for my work, nor do I think it will be in the future. However, as a professional and a graduate, I realize that my earning potential will be significant. That is why I also commit myself to charity and fairness. In the past I have been a member of the Boy Scouts of America, and have achieved the rank of Eagle Scout. In the course of my experience in that organization, I learned respect and moral value. Now, as a member of the IEEE, I value my professional standing and its commensurate moral implications. Ethics in engineering is as important as technical skill, and as such I intend to uphold my own ethical obligations to the best of my ability. As a Northeastern University student, I would commit all that I have to offer to my study. I intend to pursue research in MEMS technology. At Rowan University as an undergraduate student I have already conducted some research and development of MEMS sensors for military applications, resulting in publication. An article, written by myself and my project member David Bowen and edited by our advisor Dr. Robert Krchnavek, was published in the NAVSEA Intelligent Ships Symposium Proceedings of 2001. The paper was titled "Designing a 3-Axis, Monolithic, MEMS-Based Accelerometer" and was under review for endorsement by the US Navy's NAVSEA facility in Philadelphia during that year. Building on my past success in MEMs design, I hope to advance my understanding. Through research at the graduate level, it is my hope to become familiar with, and innovate the design of MEMs Optics in hopes of creating a reliable and practical MEMs Electro-Optical Interface for use in consumer electronics. It is my hope, that through my research, optical waveguides for intradevice communication might be realized. Finally, my intent to pursue graduate study is laid plain. Study of MEMs optics is my intended focus, and I am committed to my goal. In pursuing a doctoral degree, I have closely analyzed myself to determine the reasons for my previous successes and my goals for the future. I have found that I do and have always enjoyed engineering, and that I have a strong desire to pursue my study further. I am prepared to commit myself to that study, and achieve what I have set out to do. 3I Wish to Pursue an MS Degree in Electrical Engineering During my senior year at Purdue University, I made a decision that has impacted the entire course of my education. While my classmates were making definite decisions about their career paths, I chose to implement a five-year plan of development and growth for myself. I designed this plan in order to examine various careers that I thought might interest me, as well as to expand upon my abilities at the time. As I was attaining a BS degree in Electrical Engineering, I decided to focus primarily on fields related to the VLSI (Very Large-Scale Integrated) circuits area. My main goals were either to gain work experience or to further my education by pursuing an MS degree in Electrical Engineering (MSEE). I saw an opportunity to both work and learn through employment at Xilinx Inc. Operating as a product engineer at a successful, high-tech semiconductor company has enabled me to utilize my technical and interpersonal skills in new and challenging ways. The position has also allowed me to interact with a multitude of departments including marketing, integrated circuit (IC) design, software/CAD development, manufacturing, reliability, accounting, and sales. I thus have gained an array of experience that extended beyond the parameters of my own responsibilities. In the workplace, I rely heavily upon the interpersonal techniques I developed as a counselor in a Purdue residence hall, as well as the organizational skills I had acquired through holding various leadership positions in cultural and engineering societies. I have also cultivated an interest in high-technology marketing that has continued to grow throughout my career. My experiences with Xilinx have heightened my hunger for knowledge in the VLSI field. Two months after joining the corporation, I applied to several part-time programs in the vicinity that would allow me to acquire an MSEE degree within two to three years. San Jose State seemed an ideal choice, for its evening MSEE courses would allow me to pursue two independent, full-time positions concurrently. The San Jose program has complimented my Xilinx duties well; both demand large levels of energy and enthusiasm while guiding me to my ultimate goal a high degree of education in VLSI sciences. The resources that I poured into both endeavors have reaped many gains. I have been promoted to a Product-Yield Engineering position within Xilinx's Coarse Grain Static Memory (CGSM) Product Engineering division. My extensive coursework plays a key role in my continued success at Xilinx. Relevant classes in advanced digital and analog VLSI design, as well as sub-micron ULSI technology, have allowed me to understand more completely the workings of Xilinx, a fab-less semiconductor company that also functions as a software and hardware design, testing, and marketing center. The gains in knowledge I have made through the combination of work experience and education have indeed been exponential. The academic records of my senior year at Purdue, coupled with my MSEE coursework, are ample proof of my dedication to learning. I feel I have overcome through hard work and dedication the brief "dry phase" I underwent at Purdue during the close of my sophomore and the first semester of my junior years. My performance at that time is in no way indicative of my usual achievements; they are instead the result of urgent family difficulties that required much foreign travel and serious attention to resolve. In May, I shall graduate with an MSEE degree from San Jose well ahead of my original estimates. This early graduation with Dean's Honors is the result of my firm belief in the value of diligence, as well as my renewed determination to strive for perfection in both work and school. I am now embarking on another five-year plan, during which I hope to fulfill several specific career goals. For instance, being part of a very dynamic and results-oriented Yield team at Xilinx calls for continuous development of computational and statistical techniques. The Yield team is divided to focus on specific process/fabrication issues and process (manufacturing) optimization. My own position is an integral part of the optimization group. Speed and cost issues continue to press high technology atmospheres towards optimization, probability and stochastic processes and systems, and rigorous simulations of mathematical models. The MS in EES&OR offered at your university will grant me the statistical knowledge that is crucial for process and production optimization in a fab-less environment. In addition, product engineering requires fundamental research on mathematical models for linear and non-linear programming, as well as the utilization of efficient computer software. I continuously employ the knowledge I gained at Purdue in Operations Research and advanced mathematics courses. Yet despite the value of these classes and my high performance in them, I now require further education to best fulfill my duties. An MS in the EES&OR field, will give me knowledge that is invaluable to a career in product development, project management and strategic planning. The program will allow me to improve decision-making skills in operations, strategy, and policy issues. I will strengthen my theory and application in countless areas:continuous, discrete, numerical optimization; probabilistic and stochastic processes; dynamic systems and simulation; economics, finance, and investment; decision analysis; dynamic programming and planning under uncertainty; operations and service; corporate and individual strategy; and private and public policy , the EES&OR program will not only help me to excel at Xilinx but will also further any future career. My commitment to work and education over the last three years proves that I will pursue this MS with enthusiasm and technical edge that the MS would provide is I will be working while attending Stanford, I shall mingle education with practical application, and bring to the table interesting problems from my experience and past education. Technical challenges encountered through projects in the EES&OR program will provide motivation and opportunity for methodological data collection, processing and presentation issues presented are integral to my future goals, and the management challenges raised will provide invaluable experience for professional practice. This will in turn build a solid foundation for a life-long career that can overcome any problem in decision-making. In addition, taking courses in economics, finance, and investment analysis will allow much growth of knowledge in investment issues in different industries. The EES&OR program thus appeals not only to my engineering, economics, science and mathematical background, but will compliment my technical abilities with the conceptual frameworks needed to analyze problems in operations, production, strategic planning, and marketing in the realm of emiconductor/IC/engineering systems. I feel that I am prepared to meet the challenges of the curriculum. My coursework in intermediate microeconomics and macroeconomics, international trade, operations research, linear algebra, and probabilistic methods, along with my extensive calculus background, will allow me to function well within the program. My long-term career goals include a move into marketing and product management. I believe that attaining this MS degree is the cornerstone to achieving my goals. It will give me the academic background necessary to succeed in product development, project management, and strategic planning. It will improve decision-making skills necessary for optimizing performance. The integration of two excellent programs in Economics Systems and Operations Research thus suits my current position and ties in with future goals perfectly by improving decision making in operations, strategy and policy. At present I desire to continue at Xilinx; attending a program that provides the flexibility and convenience of the SITN, is therefore imperative. Hence, being at Stanford as an HCP student alsoattracts me. I believe that Stanford is the best environment for me to achieve my goals while gaining exposure to and experience with a diverse student body and faculty. It is my belief that one continues to learn throughout one's life, and the most effective method of learning is through interaction with 's diversity offers an environment for learning, both inside and outside the classroom. I hope to share my varied knowledge with my classmates and to take from them a new understanding of topics that are foreign to me. I believe that no other school provides students with the combination of education and environment offered by Stanford. Its outstanding academic reputation, mingled with its diverse environment and thriving Bay Area location, creates an opportunity for growth that is second to none. I have many ambitions for myself as I embark on this stage of my life. I believe that an education from Stanford will provide invaluable experiences and skills that will allow me to become a successful and innovative business leader in the new millennium. 4Research Department of Biomedical Engineering is designed to research on and solve the bio-electrical and biomagnetic engineering problems in the field of biology and medicine with the aid of engineering principles and methods.

2、与物理科学的联系更加紧密。由于三极管的发明和大规模集成电路制造技术的发展,固体电子学在二十世纪的后半叶对电气工程的成长起到了巨大的推动作用。电气自动化与物理科学间的紧密联系与交叉仍然是今后电气自动化的关键,并且将拓宽到生物系统、光子学、微机电系统。

3、现代技术的迅速发展。现代技术的飞速进步和分析方法、设计方法的'日新月异,势必带动着依赖现代技术的电气自动化也将迅速发展起来。

三、电气自动化的发展方向

1、电气自动化产品创新

电气自动化生产企业能够按照国家中长期科技发展规划纲要提出的目标任务,不断提高开放条件下的原始创新能力、集成创新能力和引进消化吸收再创新能力。进一步提高自身产品的科技含量,研发生产更好的具有自主知识产权的电气自动化控制系统与产品,加大自主创新的发展力度,提供了更多、更大的空间。确立企业在技术创新中的主体地位,完善体制机制和政策环境,加快实施国家重大科技专项。我国目前已经形成了中低挡产品以国内企业为主,中小型项目选用国内产品的市场格局。电气自动化生产企业应当努力开创科学发展的新局面,坚持提高自主创新能力,加快转变经济增长方式,不断提高自主创新能力。

2、电气自动化系统平台统一化

电气自动化系统平台统一化可以支持一个自动化项目周期中的设计、实施和测试、调试和开机、运行及维护等各个阶段和环节。这样可以大大降低从设计到完成的时间和费用。统一的系统开发平台还可以满足用户另一个重要需求即开发平台立于最终的运行平台。根据项目特点和最终用户需求决定将统一的运行代码下载到硬件PLC、基于Windows NT 的软件PLC、嵌入式NT 系统还是基于WindowsCE 的控制系统中。

3、电气自动化系统结构通用化

电气自动化系统结构通用化对于一个成功的电气自动化控制系统来说非常重要。整个企业的网络结构应保证现场控制设备、计算机监督系统、企业管理系统之间的数据通讯畅通无阻。企业管理层可通过lnternet/Intranet 对现场设备进行实时监督。在进行系统网络规划时,无论选择与现场设备通讯的现场总线还是与上级计算机或办公系统通讯的以太网,所选择的网络产品必须能够保证从办公自动化环境到控制级直至元件级的整个系统范围内的通讯。

4、电气自动化系统程序接口标准化

基于微软公司的标准和技术,如WindowsXP、OPC 和ActiveX,减少了工程时间和费用,方便了电气自动化系统和办公系统的数据交换与共享。在与企业的MES 系统、ERP 系统连接时,基于PC 平台的自动化解决方案至关重要。使用Windows XP 作为操作系统,使用TCP/IP作为办公环境的通讯标准,PC 可以在自动控制和管理平台之间建立一种最好的接口。标准化的程序接口还保证了不同厂家的软硬件产品的数据交换,切实解决它们之间的通讯障碍。

5、电气自动化生产安全化

我国电气自动化企业应当认识到安防行业技术多系统集成一体化的大趋势。强调安全控制系统和非安全控制系统的集成。让客户在现有的非安全控制系统的基础上,以较低的开发设计成本实现自己的安全方案,也同样是我们目前应该思考的问题之一。电气自动化安全系统与产品将会成为未来自动化领域的一个亮点。针对市场特点,循序渐进开拓市场。可以先从安全等级要求最高的应用领域入手,逐步拓展到其他危险等级较低的场合。按照从工厂设备层到网络层,从硬件到软件,从安全单元到安全系统的路线进行电气自动化系统安全方案的应用。努力开展电气自动化安全防范系统设计的研究。尤其是在楼宇智能化集成系统领域。

6、操作人员专业化

电气自动化系统设计与安装时,往往忽略对那些将直接接触控制设备人员培训工作。这是通常认为实际运行设备时进行人员培训比较容易,许多生产厂家及工程部门直到系统安装运行之后,才开始对操作人员及维护人员进行系统培训。系统安装过程中,随时让将来最终要维护和操作该设备人员了解安装过程,这将使他们对新系统有感性认识。通过专业培训,操作人员能更好理解系统为何按某一特定方式安装。为应付突然出现故障及恶劣运行环境下维修,就要事前弄清楚原因,否则会影响对发生问题做出正确判断。新系统安装,操作人员必须掌握这些技术。培训期间,公司培养技术娴熟操作人员,系统可运行时,那些将接触新系统人员掌握硬件设备及其操作和维护保养知识。

随着智能化和信息化的逐步发展,电气自动化涉及的产业和领域也将更多,技术更新更快,更加复杂,我们应当不断吸收高新技术的营养,开创电气自动化发展新局面。

毕业论文范文--计算机科技发展综述及展望

计算机于上世纪世纪70年代末期开始普及以来,短短的几十年时间,其对人类经济、军事、文化、艺术、生活乃至政治便已产生了不可估量的巨大影响。所以,我们很有必要对计算机的发展历程及未来发展做一全面的了解。本文由于篇幅所限,只能抓住计算机发展的关键节点加以综述。

在一开始,人们预测计算机可能会具有人类的某些智能,事实上,这一课题早已不再是科学幻想,而是非常严肃的科技应用了。但在此,我们需要再追述一下当时的历史:美国麻省理工学院社会学教授特克尔是计算机心理学方面的专家,曾经撰写过两本关于计算机心理学的具有开创性的著作,一本是《第二自我:计算机和人类精神》,另一本是《计算机屏幕上的生活:因特网时代的特征》。特克尔从20世纪70年代末开始研究人和计算机的关系。她说:“计算机的特征在( )物体和非物体之间。”很明显,计算机是物体,但在另一方面,计算机又可以反馈,可以有行为,有理智,甚至有精神。人们发现自己和计算机之间存在着互动的关系,甚至感到计算机似乎活着。

特克尔教授对儿童、计算机以及电子玩具三者之间的关系特别感兴趣。她发现,十来岁的少年主要用计算机来探索认知的问题,而八岁到十二岁之间即青春期以前的儿童,主要试图熟练掌握机器和电子玩具。特克尔发现计算机玩具对五岁到八岁之间的儿童起到激发纯理性推测思维的能力。她说,这些计算机玩具促使我们考虑“什么是生活”这一类的问题。

讨论计算机到底和人类有哪些区别,这无疑是一个最重要的问题。或许将来可能会出现和人类一样聪明的计算机,但是人类仍然要做饭,要建立家庭,要开餐馆,人类可能是地球上唯一会去教堂的生物。换句话说,计算机为人类留下的空间是感情、感性、家庭生活。模拟思维可能在某种程度上可以算是一种思维,但是模拟感情却永远不能被看作是真正的感情。

微软公司的视窗操作系统是特克尔目前重点研究的课题。视窗系统允许使用者同时执行几个互相没有任何关系的工作任务,并随意在这几个任务之间相互切换。这显然是一场革新,因为微软视窗允许使用者在计算机上同时发出好几个指令,并且在这些指令之间不断循环往复,这已经具备人类心理活动的某些特点。

在20世纪80年代,人类可能可以通过和自己心理的比较来试图理解计算机;而今天,特克尔说,人类试图通过计算机的运行模式来更好地理解人类的心灵。特克尔认为,现在计算机心理学研究的最热门话题是假设计算机到最后会真正动感情——你的计算机会对你产生爱情,它需要你的关怀、需要感情的滋润——这可能是未来研究人和机器间互动关系领域里最新的潮流。

目前人类在计算机控制的智能玩具领域已经取得了一些突破。一些玩具可以说几百句话,而且具有学习功能,甚至会骂人。日本索尼公司制造的电子宠物狗IBO,是这类电子宠物玩具的代表性产品。除了玩具以外,在智能计算机方面,计算机能够听懂主人说话已经不算稀奇。目前美国麻省理工学院的媒体研究室已经研制出一种具有人工智能的计算机,可以对使用者发出的非语言性信号做出反应,并且据此进行某种程度的调整。

特克尔认为,未来的计算机发展趋势是生物化计算机,计算机越来越具有知性和感性。从社会学的角度上说,这将是一大飞跃,值得学者专家好好探讨。

目前的计算机以纳秒(十亿分之一秒)为运算单位,其速度大大超过人脑,相当于人脑运算能力的一百多万倍。但是,计算机依然远远赶不上人脑信息处理能力的多样性。

为什么计算机的“智力”与人类不一样呢?原因之一就在于二者信息处理模式的不同。计算机的信息处理基础是对由记号来体现的概念的逻辑操作,而人脑的信息处理则是以图形为基础的非线性、并行的复杂能力。也可以这样说:计算机运用的仅仅是逻辑思维,而人的大脑运用的不仅是逻辑思维,更有形象思维。显然,人的大脑考虑问题比计算机更合理、更准确、更科学,因而效率更高,速度更快。

有人尝试模仿人脑模式制作具有人类特有功能的计算机,日本ATR人类信息通信研究所目前正在开发整体模仿人脑的计算机。由于迄今为止并没有完全弄清楚人脑的机制,因此在“脑型计算机”领域进行的研究不止一种。

人脑的神经线路并不是起初就非常完善的,而是在成长的过程中通过神经细胞相结合,从而形成了神经线路。把这一过程作为硬件建设而加以实现的是“以硬件进化为基础的自我增殖型人工计算机”。这种被称作CAM智囊的系统,将包含数十亿到数百亿的神经细胞,并以这些神经细胞完全能够并行运作为目标。

有些科学家专门着眼于用计算机来实现人脑的部分功能。人脑是以细胞层多层重叠的三维结构和高度的并行处理性为特征的。基于这种认识,日本东北大学进行了具有层叠型结构的人工视网膜芯片的开发,并有望制造出具有近似于人的视觉信息处理功能的系统。日本物理化学研究所最近开始通过开发高级小型机器人来探索脑型计算机的研制。该研究所根据人脑的处理线路让不同的小型机器人模拟人脑,用以对大脑认知、学习和控制等问题进行研究。

目前人们主要通过三种途径开发像人脑一样有自律性和创造性、能进行高度智能作业的计算机。一是人工智能的研究;二是以人脑结构为模型,制成以人工神经细胞为基础的脑型计算机,这也被称为神经计算机;第三种途径是开发能像神经网络一样工作的电子线路来自动生成“人工脑”。

脑型计算机的研究范围非常广泛,但如今的大部分工作仍处于基础阶段。因为要弄清楚人脑的机制并不容易。专家们认为,要想了解极其复杂的人脑的作用,就必须进行跨学科的多方面研究,进行综合、整理以获得全面信息。例如,通过了解大脑工作时的生理学功能,可以在神经细胞研究阶段得到精细的研究成果,但要在宏观上捕捉人脑活动则存在一定困难。另外,人脑同整个身体的关系等重大的课题也非常重要,如果不能发挥综合能力,就难以弄清楚大脑的工作原理。

电力系统自动化是一项综合性质的技术,包含内容广泛,并且随着时代的发展,经济水平的提高,生活质量的提升,对于电力的需求和利用也就越来越大。下文是我为大家搜集整理的关于电力系统自动化毕业论文范文的内容,欢迎大家阅读参考! 电力系统自动化毕业论文范文篇1 试析电力系统调度自动化 【摘 要】阐述了我国电网的现状、电力系统调度运营所包含的内容、所要实现的目标以及电力系统自动化的组成和目前所存在问题的解决方案,并对电力系统调度自动化的未来进行了展望。 【关键词】电力系统;调度自动化;信息 一、传统配电网实现电力系统自动化研究现状分析 电力系统的自动化发展主要是在配电网的上加强其自动化,因此为了提高其供点质量以及供电的可靠性,在进行电力系统自动化分析的时候,主要从配电网上实现其自动化,使得整个电力系统的发展符合当前的科技要求。目前配电网在实现自动化下,通常在10kv辐射线或者是树状的线路进行重合器以及分段器的方式来构成配电网,由于这种方式在现实自动化的过程中,不需要在配置通道上与主站的系统组成上,需要依靠重合器以及分段器本身的功能来实现电力的隔离和恢复功能,从而到电力系统的自动化,此种方法不仅具备相应容易实施的特点,而且还有节省投资的优点。同时还有其他实现电力系统自动化的接线方式,对于这些配电网的接线方式以及整个系统的构成,都具有一定的缺陷性,因此随着科学技术的提高,目前计算机网络技术正在快速的发展,使得在实现电力系统自动化发展的阶段可以对其进行改进,期改进的状态也在不断的发生着变化。 二、电力系统调度与运营包含的内容和要实现的目标 (一)电力系统调度的任务。 电力系统的调度就是对电力系统中所有的设备及其运行状态进行监控和调节,是一个指挥者。目前电力调度涵盖的范围较大,有自动化系统、继电保护等等。电力系统调度的任务主要是:尽设备最大能力满足负荷需要,使整个电网安全可靠连续供电,保证电能质量,经济合理利用能源,保证发电、供电、用电各方合法利益。 (二)调度自动化的必要。 电力系统是一个庞大而且复杂的系统,有几十个到几百个发电厂、变电所和成千上万个电力用户,通过多种电压等级的电力线路,互相连接成网进行生产运行。电能的生产输送过程是瞬间完成的,而且要满足发电量和用户用电量的平衡。现在电力系统的发展趋势是电网日益庞大,运行操作日益复杂,所以当电网发生故障后其影响也越来越大。另一方面,用户对供电可靠性和供电质量的要求日趋严格,这就对电力系统运行调度人员和电力系统调度的自动化水平提出了更高的要求。电网调度自动化具有较大的经济效益,可以提高电网的安全运行水平。当发生事故时调度员能及时掌握情况,迅速进行处置,防止事故扩大,减少停电损失。地调采用自动化调度系统能减少停电率。当装备有直接监护用户的自动装置以后,可压低尖峰负荷。若采用分时和交换电价自动计量等经济办法管理电网,经济效益更大。因此,电网调度自动化是一项促进电力生产技术进步和有显著经济效益的重要工作,是电力系统不可缺少的组成部分。 (三)电网调度自动化的组成部分及其功能。 电网调度自动化系统,其基本结构包括控制中心主站系统、厂站端(RTU)和信息通道三大部分。根据功能的不同,可以将此系统划分为信息采集和执行子系统、信息传输子系统、信息处理子系统和人机联系子系统。信息采集和执行子系统的基本功能是在各发电厂、变电所采集各种表征电力系统运行状态的实时信息,此外还负责接收和执行上级调度控制中心发出的操作、调度或控制命令。信息传输子系统为信息采集和执行子系统与调度控制中心提供了信息交换的桥梁,其核心是数据通道,它经调制解调器与RTU及主站前置机相连。信息处理子系统是整个调度自动化系统的核心,以计算机为主要组成部分。该子系统包含大量直接面向电网调度、运行人员的计算机应用软件,完成从采集到信息的各种处理及分析计算,乃至实现对电力设备的自动控制与操作。人机联系子系统将传输到调度控制中心的各类信息进行加工处理,通过各种显示设备、打印设备和其他输出设备,为调度人员提供完整实用的电力系统实时信息。调度人员发出的遥控、遥调指令也通过此系统输入,传送给执行机构。 我国调度自动化水平与世界上先进的国家相比,还有一些差距。尽管在近几年新投入运行的变电所采取了比较新的技术,但是总体而言,电网调度系统还存在一些需要解决问题。例如:系统计算机CPU负载率问题,即便是目前计算机容量和运算速度成倍或成几十倍提高的情况下,其负载率仍很高;CDT和Polling远动规约的选用问题,CDT和Polling两类规约在我国得到了广泛应用,并且这两类规约远动装置并存使用的现状将持续下去,选用哪一类规约的远动装置,原则上应视通道的质量与数量及本电网的调度自动化系统现状来决定,不宜盲目追求采用Polling远动;系统的开放性问题,系统应该是开放的,能够支持不同的硬件平台,支持平台采用国际标准开发,所有功能模块之间的接口标准应统一,支持能过户应用软件程序开发,保证能和其他系统互联和集成一体或者方便实现与其他系统间的接口,系统应能提供开放式环境。此外,现在的电力系统由于还依赖高压机械开关(油断路器、六氟化硫断路器、真空开关等)实现线路、设备、负荷的投切,尚不能做到完全可控。这是因为机械的慢过程不可能控制电的快过程引起的。“电网控制”目前只能做到部分控制,本质上仍然是一个调度员的决策支持系统。如果电力系统的高压机械开关一旦被大功率的电子开关取代,则电力系统真正的灵活调节控制便将成为现实 三、电力系统调度自动化存在问题的解决方法 (一)管理方面 统一思想,加强调度管理,提高认识。必须杜绝人为的一切误调度、误操作事故以及不服从调度指令擅自投停运设备。抓好防治误操作的思想教育工作,增强广大调度人员的安全意识、责任心和技术素质,最大限度避免误操作事故的发生。加大奖惩力度,严格考核,加强安全监督检查。认真落实各级安全生产责任制;严格执行“两票三制”制度,严把安全关。加强调度专业培训,提高调度员业务水平。 (二)技术方面 积极开发更高级实用的装置和软件,努力提高自动化水平和保证通信的清晰畅通,避免工作中出现因电话不清楚、自动化画面显示不正确而造成的错误。 随着计算机技术、通信技术的发展以及电力系统控制技术的不断进步,在不远的将来,电力系统调度自动化将会取得飞速的发展。以这些科学技术的进步为依托,能更好地维持供需平衡,保证良好的电能质量。 电力系统自动化毕业论文范文篇2 浅析电力系统自动化技术 【摘 要】随着电力电子技术、微电子技术沟迅猛发展,原有的电力传动(电子拖动)控制的概念已经不能充分概抓现代生产自动化系流中承担第一线任务的全部控制设备。而且,电力拖动控制已经走出工厂,在交通、农场、办公室以及家用电器等领域获得了广泛运用。它的研究对象已经发展为运动控制系统,下面仅对有关电气自动化技术的新发展作一些介绍。 【关键词】电力自动化;现场总线;无线通讯技术;变频器 0 引言 现今,创新的自动化系统控制着复杂的工艺流程,并确保过程运行的可靠及安全,为先进的维护策略打造了相应的基础。 电力过程自动化技术的日新月异和控制水平的不断提高搜企网版权所有,为电力工业解决能源资源和环境约束的矛盾创造了条件。随着社会及电力工业的发展,电力自动化的重要性与日剧增。传统的信息、通信和自动化技术之间的障碍正在逐渐消失。最新的技术,包括无线网络、现场总线、变频器及人机界面、控制软件等,大大提升了过程系统的效率和安全性能。 电力系统自动化系统一般是指电工二次系统,即电力系统自动化指采用各种具有自动检测、决策和控制功能的装置并通过信号系统和数据传输系统对电力系统各个元件、局部系统或全系统进行就地或远方自动监视、协调、调节和控制以保证电力系统安全稳定健康地运行和具有合格的电能质量[1]。 1 电力自动化的发展 我国是从20世纪60年代开始研制变电站自动化技术。变电站自动化技术经过数十年的发展已经达到一定的水平,在我国城乡电网改造与建设中不仅中低压变电站采用了自动化技术实现无人值班,而且在220kV及以上的超高压变电站建设中也大量采用自动化新技术,从而大大提高了电网建设的现代化水平,增强了输配电和电网调度的可能性,降低了变电站建设的总造价,这已经成为不争的事实。然而,技术的发展是没有止境的,随着智能化开关、光电式电流电压互感器、一次运行设备在线状态检测、变电站运行操作培训仿真等技术日趋成熟,以及计算机高速网络在实时系统中的开发应用,势必对已有的变电站自动化技术产生深刻的影响,全数字化的变电站自动化系统即将出现。 2 电力自动化的实现技术 现场总线(Fieldbus)被誉为自动化领域的计算机局域网。信息技术的飞速发展,引起了自动化系统结构的变革,随着工业电网的日益复杂工业自动化网版权所有,人们对电网的安全要求也越来越高,现场总线控制技术作为一门新兴的控制技术必将取代过去的控制方式而应用在电力自动化中。 3 无线技术 无线通讯技术因其不必在厂区范围内进行繁杂、昂贵的布线,因而有着诱人的特质。位于现场的巡视和检修维护人员借此可保持和集中控制室等控制管理中心的联系,并实现信息共享。此外,无线技术还具有高度灵活性、易于使用、通过远程链接可实现远方设备或系统的可视化、参数调整和诊断等独特功能。无线技术的出现及快速进步,正在赋予电力工业领域以一种崭新的视角来观察问题,并由此在电力流程工业领域及资产管理领域,开创一个激动人心的新纪元。 尽管目前存在多种无线技术汉阳科技,但仅有几种特别适用于电力流程工业。这是因为无线信号通过空间传播的过程、搭载的数据容量(带宽)、抗RFI(射频干扰)/EMI(电磁干扰)干扰性、对物理屏障的易感性、可伸缩性、可靠性,还有成本,都因无线技术网络的不同而不同。因此,很多用户都倾向于“依据具体的应用场合,来选定合适的无线技术”。控制用的无线技术主要有GSM/GPRS(蜂窝)、9OOMHzRadios、wi-Fi()、WIMAX()、ZigBee()、自组织网络等,其中尤以Wi-Fi和WIMAX应用增长速度最快,这是因为其在带宽和安全性能方面较优、在数据集中和网络化方面具备卓越的安全框架、具有主机数据集成的高度灵活性、高的鲁棒性及低的成本。 4 信息化技术 电力信息化包括电力生产、调度自动化和管理信息化两部分。厂站自动化历来是电力信息化的重点,大部分水电厂、火力发电厂以及变电站配备了计算机监控系统;相当一部分水电厂在进行改造后还实现了无人值班、少人值守。发电生产自动化监控系统的广泛应用大大提高了生产过程自动化水平。电力调度的自动化水平更是国际领先,目前电力调度自动化的各种系统,如SCADA、AGC以及EMS等已建成,省电力调度机构全部建立了SCADA系统,电网的三级调度100%实现了自动化。华北电力调度局自动化处处长郭子明说,早在20世纪70年代华北电力调度局就用晶体管计算机调度电力,从国产121机到176机,再到176双机,华北电力调度局全用过,到1978年已经基本实现了电网调度自动化。 5 安全技术 电力是社会的命脉之一,当今人类社会对电力系统的依赖已到了难以想象的程度。电力系统发生大灾变对于社会的影响是不可估量的,因此电力系统最重要的是运行的安全性,但这个问题在全世界均未得到很好解决,电力系统发生大灾变的概率小但后果极其严重,我国电力系统也出现过稳定破坏的重大事故。由于我国经济快速发展的需求,电力工业将会继续以空前的速度和规模发展。随着三峡电站、西电东送、南北互供和全国联网等重大工程的实施,我国必将出现世界上最大规模的电力系统。 6 传动技术 实现变频调速的装置称为变频器。变频器一般由整流器、滤波器、驱动电路、保护电路以及控制器(MCU/DSP)等部分组成。变频器作为节能降耗减排的利器之一,在电力设备中的应用已经极为广泛而成熟。对于变频器厂商而言,在未来30年,变频器,尤其是高压变频器在电力节能降耗中的作用极为明显,变频器也成为越来越多电力行业改造技术的首选。 在业内,以ABB为首的电力自动化技术领导厂商,ABB建立了全球最大的变压器生产基地及绝缘体制造中心。自1998年成立以来,公司多次参与国家重点电力建设项目,凭借安全可靠、高效节能的产品性能而获得国内外用户的好评。其公司多种产品,包括:PLC、变流器、仪器仪表、机器人等产品都在电力行业中得到很好的应用。 7 人机界面 发电站、变电站、直流电源屏是十分重要的设备,随着科学技术的不断发展,搜企网,单片机技术的日趋完善,电力行业中对发电站、变电站设备提出了更高精密、更高质量的要求,直流电源屏是发电站、变电站二次设备中非常重要的设备,直流电源屏承担着向发电站、变电站提供直流控制保护电源的作用,同时提供给高压开关及断路器的操作电源,因此直流电源屏的可靠性将直接关系到发电站的安全运行,直流电源屏的发展已经经历了很长的时间,从早期的直流发电机、磁饱和直流充电机到集成电路可控硅控制直流充电机、单片机控制可控硅充电机、高频开关电源充电机等,至目前直流电源屏已很成熟。 直流电源屏整流充电部分仍然采用目前国际最流行的软开关技术,将工频交流经过多级变换,最后形成稳定的直流输出,直流电源屏系统控制的核心部件是V80系列可编程控制器PLC,它将系统采集的输入输出模拟量以及开关量经过运算处理,最终控制高频开关电源模块使其按电池曲线及有人为设置的工作要求更可靠地工作。 8 结束语 电气自动化技术是当今世界最活跃、最充满生机、最富有开发前景的综合性学科与众多高新技术的合成。其应用范围十分广泛,几乎渗透到国民经济各个部门,随着我国科技技术的发展,电气自动化技术也随之提高。 【参考文献】 [1]汪秀丽.中国电力系统自动化综述[J].水利电力科技,2005(02).
