沙河抽水蓄能励磁系统静差及调差率试验分析

Excitation system static error and adjusting error ratio test of Shahe pumped-storage power station

沙河抽水蓄能机组励磁设备成功进行了国产化改造工作,使用南瑞继保的RCS-9400型励磁调节器。为检验其可靠性,对改造后的励磁系统进行了静差及调差率试验分析。结果:沙河励磁调节器调差极性正确,具备正常调差功能,其调差率和静差率满足规程要求。

The excitation system of Shahe pumped-storage power station was upgraded with the RCS-9400 type excitation regulator manufactured by NR Electric. Excitation system static error and adjusting error ratio test was conducted to check the reliability. The results of test demonstrate that domestic excitation regulator has correct polarity, normal adjusting function, with the adjusting error ratio and static error ratio up to requirements of specifications.
