PLC技术在变电站电容器控制中的应用分析

Application Analysis on PLC Control Technology in Transformer Substation Capacitors

针对110kV变电站投入的II段电容器不能自动投切、浪费电能、影响设备稳定运行的现状,提出将PLC技术应用于110kV变电站电容器控制的方案,从一次设备网络化改进、二次系统集成化管理、变电站运行稳定性控制等方面分析了PLC技术的应用情况及效果,结果表明该技术的应用降低了有功损耗和无功损耗,利于电力系统的安全、稳定、经济运行。

The section II capacitor that used in 110 kV substation cannot switch automatically,which will lead to the waste of electricity and bad effect on stable operation of equipment,this paper puts forward the project that applied PLC technology to the110 kV substation capacitor control,and analyzes the PLC technology application and effects from the aspects of primary equipment networked improvement,secondary system integrated management,substation operation stability controlling,the results shows that this technology application can reduce active power loss and reactive power loss,to be good for safe,stable,economical operation.
