摘要

首先介绍了特高压某换流站无功控制动作导致直流功率回降的事件; 具体分析了手动切除 HP3 滤波器导致直流功率回降的故障原因，并指出了绝对最小滤波器控制功能软件存在的问题; 最后在现有无功控制功能基础上，分析了满功率运行情况下存在的安全生产隐患，同时提出了可行性解决方案，为国内其他换流站提供了相应的借鉴。

Abstract

Firstly，the event that UHV reactive power control action leads to DC power runback is introduced． And then，the causes for DC power runback led by manual removal of HP3 filter are analyzed，and the problems existing in control function software of the absolute minimum filter are pointed out． Finally，on the basis of the existing reactive power control function， the hidden dangers in full power operation situation are analyzed，and the feasible solutions are proposed，which can provide a reference for other converter stations in China．
