一种电容器组串联电抗器谐波过载保护的实现方法
摘要
谐波背景条件下
电抗器的谐波敏感度远大于电容器
特别是铁芯电抗器。本文介绍一种有别于传统只单纯考虑谐波有效值的电容器组谐波保护
提出通过测量考虑谐波频率的工频等效电流及工频等效电压
实现电容器组用铁芯电抗器过电流保护和噪音控制的方法
并通过真型样机在实验室及现场投运验证。
Abstract
Under harmonic background conditions
the harmonic sensitivity of reactors is much greater thanthatofcapacitors
especially iron core reactors. In this paper
a new type of harmonic protection for capacitor bank
which is different from the traditional only considering the harmonic effective value is introduced. The method for over current protection and noise control of core reactor for capacitor bank by way of measuring power frequency equivalent current and voltage considering harmonic frequency is proposed and therealprototypepassedtheoperationverificationinthelaboratoryandsite.
