摘要
多年来发电厂的发电机组均采用直流电励磁。因而,在转子中产生铜耗,汽轮发电机约占总发电量的0.4%左右,水轮发电机约占总发电量的1%左右。文章着重分析发电机转子应用永磁体的利弊。
The generator set in the power plants adopts DC exciting for years, therefore, resulting in the copper loss in the rotor, occupying 0.4% of total output for the steam turbine generator while 0.1% for water wheel turbine one. The article focused on the advantages of the generator＇s rotor employed with the permanent magnet.
