摘要

结合逆变侧换流变压器阀侧接地故障下的理论分析和仿真试验，分析了目前各直流输电工程中发生逆变侧换流变压器阀侧接地故障、相关保护动作后投入旁通对时可能导致健全极保护动作并停运的问题，并探讨了相关改进措施，对完善直流保护动作策略、提高系统可靠性有一定的参考价值。

Abstract

Combined with theoretical analysis and simulation test， the characteristics of grounding fault at converter transformer valve side of inverter station are analyzed. With the action of the protection related to the grounding fault at converter transformer valve side of inverter station， the valve bypass would be requested and this action strategy would affect the operation of another pole. At last， some improvement suggestions are discussed， which are valuable to complete the action strategy of high voltage DC（HVDC） transmission protection and improve reliability of the HVDC system.
