摘　　要：一般200 MW容量等级火电机组发变组保护均配置有程序逆功率保护,但在发电机先解列等特殊情况下,安全停机面临风险。为此,介绍了防止电力生产事故的25项重点要求中对机组停机解列的要求,在分析汽轮发电机解列后安全停机存在的问题的基础上,探讨了解决方案。Generally,the generator-transformer unit protection of 200 MW thermal power units is equipped with program reverse power protection,but in special situations such as generator disconnection,safe shutdown faces risks.In order to prevent power production accidents,the requirements for unit shutdown and disconnection among the 25 key requirements are introduced.On the basis of analyzing the problems of safe shutdown after the disconnection of the turbo-generator,the feasible solutions are discussed.
