摘要

交直流滤波器在运行中发生的故障将直接影响直流输电工程的能量可用率

而交直流滤波器的电容器又是较容易发生故障的设备。为提高直流输电工程的能量可用率

本文提出了对直流输电工程中电容器采取特殊维护的措施

介绍了特殊维护的周期、项目和标准。通过统计对比4个换流站特殊维护前后滤波器电容器的故障率

证明了该措施可以有效降低滤波器在运行过程中的电容器故障率。并介绍了在特殊维护过程中发现的典型电容器故障以及处理办法。

Abstract

The failure of AC/DC filter in operation will directly affect the energy availability of DC power transmission project

and the capacitor of AC/DC filter is the equipment prone to fault.For improving energy availability of DC power transmission

the special maintenance measures to the capacitor for DC transmission project is proposed

the interval

items and standards of the special maintenance are introduced.It is proved through comparing the fault rate of filter capacitor of four converter station before and after special maintenance that the measure can effectively reduce the fault rate of filter capacitor during operation.And typical faults of capacitor found in special maintenance period and treatment solution are introduced.
