Study Of The Area Automatic Switchover Control System In Zhaoqing Power Grid

As zhaoqing economic growth, social progress, the user requirements for power supplyquality and reliability is higher and higher, how to ensure that the whole society becomezhaoqing power supply bureau a social responsibility. Although construction in order toimprove power supply reliability of power grid in recent years a large amount of investment,zhaoqing power grid all220kV substation and110kV substation has been widely usedmicrocomputer for the vote, successfully used in power grid power electromagnetic loopnetwork point control, fault isolation and power supply recovery area. Zhaoqing powernetwork are still exist space truss structure is weak, single single variable power supply, along stand collusion and influence the reliability of the power supply problem. And theexisting application limitations existing in conventional prepared from the cast, in zhaoqingarea power supply reliability is extremely adverse impact. To solve the chain grid connectionof110kV substation for cast application limitations, since the implementation of powersupply and standby power supply is not in the same substation standby power intelligent input,zhaoqing power supply bureau to begin research and development for the region based onEMS area for the system.Zhaoqing power supply bureau, this paper based on the area of the EMS for the systemimplementation plan, key research based on the area of the EMS for the voting systemfunction structure, including functional requirements and the composition of functionalframework and performance requirements. Combination of zhaoqing power grid "sihui-cuizhu string"110kV chain grid connection requirements under various operation modes forshots, making area under different operation mode for the scheme, including charge anddischarge conditions, action logic, etc. The system in the formation of information acquisition,control strategy and control measures, the whole process of the implementation ofcomprehensive utilization of entire network information, realizes the prepared from thethrowing and concerted work of the safety and consistency of mechanism. In addition, thesystem automatically on control strategy and power grid security check or adjustment,improve the security of prepared from the cast of the action strategy. This article through tozhaoqing power grid based on EMS area for further study since the investment system, shows that since the area for cast technology in smart grid applications in the necessity andfeasibility.
