摘要

电网谐波是引起并联补偿电容器在运行中发生事故的主要原因

谐波含量增加会导致流过电容器电流有效值增加

致使其发热量增加

从而加速热老化

导致电容器寿命降低。以华东某500 kV变电站35 kV侧并联补偿电容器为例

计算了3次谐波和5次谐波含量对其电流有效值的影响

进而根据标准提出了该电容器组谐波含量的极限值

从而在运行中予以控制。

Abstract

The harmonic of the network is the main cause leading to fault of compensating capacitor in service.The increase of harmonic contents will lead the r.m.s value of the current flowing through the capacitor increase

accordingly resulting in an increase of its heat

thus accelerating thermal aging and reducing endurance of capacitor.In this paper

35 kV shunt compensation capacitor of a 500 kV substation is taken as an example by the author

the influence of 3rd harmonic and 5th harmonic content to the current r.m.s value is calculated

the limit of harmonic content of the capacitor is proposed as per standard and control in the operation.
