应用PLC控制改进功率因数自动补偿系统

Power factor′s Auto compensation systerm′s design with programmable controler

提高功率因数COS在电 力系统、工矿企业的成本核、节约电能中都有重要的经济意义。在电力系统、工矿企业用电网络中都装有功率因数自动补偿系统。本文分析了功率因数自动补偿控制的原理,设计了可编程控制器(PLC)功率因数自动补偿系统。

Increasing of the power factor has an important effect on saving electronic energy and cost accounting both in power systems and in factories,mines and enterprises.The paper deals with the theory of power factor′s auto compensation and provides the design of the PLC power factor′s auto compensation systerm.
