摘要
分析了某发电厂315MW发电机组在150 MW负荷下因"灭火保护动作"跳机,重新启动并网时因发电机"匝间短路保护动作"致使并网失败的原因及检查处理方法。
This paper analyzed the reason on failure of parallel in grid when restart the generator due to ＂turn-turn protection trip＂, after ＂fire protection trip＂ in 315 MW power plant under 150 MW load. The treatment was carried out.
