摘要

针对换流站HCM200直流控制保护系统单一“与逻辑模块”导致的系统故障，参考金华换流站的故障案例、对某换流站同类故障进行分析与研究，提出该模块故障后可能导致的直流输电系统告警及保护后果，并且针对性地提出此类故障、隐患排查方法及改进措施。

Abstract

This paper addresses system faults caused by the standalone “and logic module” in the HCM200 DC control and protection system at converter stations.Referencing fault instances from Jinhua Converter Station

we study and analyze similar faults at the Yinchuan East Converter Station，and discuss potential alarms and protective responses that could be triggered by a module failure

propose the targeted strategies for troubleshooting

hazard prediction

and improving countermeasures for such faults.
