摘　　要：在变频器损坏时,大容量电动机直接启动对确保电厂安全运行具有一定价值和意义。本文结合某火力发电厂的电气结构及运行方式,通过相关计算、试验及分析,作出论证了大容量电动机直接启动的可行性,对同类型电厂具有一定借鉴意义。Direct start mode of large capacity motor is of certain value and meaning to guarantee the secure operation of power plant when the converter is broken . Combined with the electrical structure and operation mode of a coal-fired power plant, the feasibility of direct starting is verified through relevant calculation , experiment and analysis. The conclusions in this paper offer certain references for similar power plant.
