摘要
阐述了隔河岩水电厂发电机停机电制动的工作原理,分析了励磁系统改造后灭磁开关运行方式变化,引起电制动投运后退出运行时转子绕组过压的原因,提出了电制动控制优化改进方案,经过试验检验,证明此方案可行。
ges of field The principle of generator electric braking in Geheyan Hydropower Plant is introduced. Operation mode chan- suppression switch after reformation of excitation system and the reasons of rotor winding overvohage during e- lectric braking quit are analyzed. Electric braking control improvement scheme is put forward and experimental testsprove the scheme is feasible.
