摘要

并联电容器是目前电网中最为常见的无功补偿设备

由于电网中存在的谐波与并联电容器组相互作用

会产生谐波放大甚至发生谐振。本文针对35 kV变电站发生并联电容器故障事故进行了详细阐述

分析了串并联谐振放大原理

通过进行现场检验、试验分析和数据图形的综合分析

指出了谐波放大是此次事故的直接原因

并提出了抑制谐波放大效应的措施。

Abstract

Shunt capacitor is the most common reactive power compensation installation in the present power grid.Harmonic enlargement and even resonance can occur due to interaction between harmonic existed in the grid and the shunt capacitor.In this paper

the fault of shunt capacitor of 35 kV substation is described in detail

the series and parallel resonance enlargement principle is analyzed.It is pointed out through site test

test analysis and comprehensive analysis of data and oscillogram that the direct reason for the fault is harmonic enlargement and the measures to suppress harmonic enlargement effect.
