This article in gives the new intelligent pharmaceutical factory BAS system in the overall concept foundation, elaborated in detail the pharmaceutical factory for the electrical power distribution system design proposal, finally carries on the simulation using the MCGS configuration software to it. This article divides into five parts: The outline, the intelligent pharmaceutical factory design rationale, the intelligent pharmaceutical factory BAS system overall concept, the intelligent pharmaceutical factory supply the electrical power distribution system the design proposal and the MCGS configuration software simulation. First first is brief in the outline part introduces the intelligent construction the system constitution and the integration, and briefing this design prime task; Then the overall introduced the intelligent pharmaceutical factory design applies rationale, including BAS basic theory, factory power supply system basic theory as well as MCGS configuration software synopsis; Then gives the new intelligent pharmaceutical factory BAS system the overall concept, including the field bus control system, guards against the system, the power equipment system, the air quality examination system peacefully, supplies the electrical power distribution system; Then acts according to the factory for the electrical power distribution system related principle, carries on the detailed elaboration to the new function pharmaceutical factory for the electrical power distribution system project design, introduced first for the electrical power distribution system voltage choice method, then gives always the voltage dropping resistor transformer substation, the live pressure and the low pressure electrical power distribution system design proposal, and the brief introduction supplies the electrical power distribution system intellectualization the realization method; Finally carries on the simulation using the MCGS configuration software to the pharmaceutical factory for the electrical power distribution system, in the detailed introduction intelligence pharmaceutical factory for in the electrical power distribution system monitoring picture design process foundation, carries on the animation demonstration, and makes a more exhaustive analysis to the simulation result. The simulation result indicated that, the new intelligent pharmaceutical factory is reliable for the electrical power distribution system power supply, the electrical energy quality is good, satisfies the production request
