摘要

交流滤波器的投切是直流输电系统运行中的重要组成部分

影响到高压直流输电系统输送功率大小和电能质量。本文对某换流站交流滤波器配置和同类型交流滤波器自动投退逻辑进行了介绍

对实际运行中出现的检修后手动操作和放电导致的交流滤波器异常投退现象进行了分析并进行了改进研究

改进后滤波器投切正常。分析了交流滤波器低电流退出功能的逻辑缺陷并提出了改进建议。

Abstract

Switching of AC filters is an important part in the operation of DC power transmission system

which affects the power transmission amount and power quality. In this paper

the configuration and AC filter automatic switching on and off logic at certain converter station is introduced; the abnormal switching circumstance of AC filter due to manual operation and discharge in the actual operation after maintenance is studied and improved;and the filter’s switching is normal after the improvement. The logic defect of low current switching off function of AC filter is analyzed and the improvement suggestion is given.
