摘　　要：文章基于±800 kV酒泉—湖南特高压直流工程中实际配备的换流阀短路保护,分析研究了其保护动作策略以及软件逻辑,并利用RTDS仿真系统对该工程典型运行工况下的两种换流阀短路故障情形进行了仿真计算,并通过仿真验证了该工程所配置的阀短路保护的可靠性。The valves short-circuit protection （ VSCP） for UHVDC can avoid the damage of the fault current effectively. Basedon the VSCP for the Jiuquan-Hunan project, this paper analyzes the action strategies and software logic of VSCP, and it usesRTDS to simulate two types of valve short-circuit under the typical operation of the project, then the effectiveness of the project’sVSCP is verified through simulation. The analysis of the results has a certain reference value for the research and construction ofthe Jiuquan-Hunan engineering.
