Wiring and Failure Analysis for Pilot-exciter& Stand-by Pilot Exciter of Excitation System 励磁系统副励与备副励的接线及事故分析
In order to increase the reliability of the excitation system for large turbogenerator and improve its response, a 70 KVA, 3,000 rpm and 400 Hz rare earth-cobalt permanent magnet ( REPM) generator has been built as a pilot exciter. 为了提高大型汽轮发电机组励磁系统的运行可靠性和响应速度,我们研制了一台70千伏安、400赫芝,3000转/分的稀土永磁发电机,作为副励磁机。
