摘　　要：小浪底水电厂发电机灭磁系统选用ABB公司的快速磁场断路器FCK配合SiC非线性电阻灭磁形式。其灭磁能量计算以发电机额定运行工况下出口突然发生三相短路时励磁绕组所流过的最大电流为基础。小浪底电站6台机组已全部投入运行,灭磁和转子过电压保护均未出现过异常情况。The generator's de-excitation system for the Xiaolangdi Hydropower Station adopted the de-excitation mode of fast magnetic breaker FCK and non-linear sic resistance which are made by ABB. The de-excitation energy calculation is based on the maximum current of the excitation winding when the generator breaker broke out a 3-phase short circuit under the rated working conditions. All six generating units of Xiaolangdi Hydropower Station have been in operation, and the faults of the de-excitation system and the over-voltage protection of the rotor have not occurred.
