摘　　要：介绍了电动机的调速逻辑及其在换流站阀水冷系统主循环泵中的应用,通过对比分析主泵的两种启动方式,并结合近几年换流站相关故障案例分析,发现主泵经软启动器启动比采用变频器调速启动具有更好的运行稳定性。This paper introduces the speed regulation of electric motor and its application in the converter station valve cooling system, by analyzing two start-up modes for the main pump in valve cooling system. Combined with the failure cases of the converter station in recent y ears, it is found that the main pump started by soft starter has better stability compared to starting by converter.
