摘要

并联电容器已被广泛地应用于电力系统中进行无功功率补偿

在其投入和退出运行时在补偿装置内部会产生过电压和过电流

甚至损坏电容器组绝缘

影响电网的安全稳定运行。文章利用EMTP/ATP电力系统暂态仿真软件

建立了330 kV变电站无功补偿仿真模型

模拟断路器同期和不同期分闸时电容器组内部过电压情况。

Abstract

Shunt capacitors are widely used in power system for reactive power compensation. However

the overvoltage and over current will be generated in the compensation device during its switch-on and switch-off operation

even the insulation of capacitor bank can be damaged and the safe and stable operation of the power grid is affected. In this paper

based on transient simulation software of EMTP/ATP power system

the reactive power compensation simulation model of 330 kV substation is set up to simulate the internal overvoltage of capacitor bank at synchronous and asynchronous opening of circuit breaker.
