摘要
以中电国华北京热电分公司200 MW汽轮发电机组为例,从进汽门活动性试验、汽门严密性试验、超速试验功能组、甩负荷过程中汽机转速控制等方面对汽轮发电机组的防超速措施进行分析,并介绍了这些功能在实际生产中的应用情况。
The 200 MW turbo-generator of Zhongdian Guohua Beijing Thermal Power Branch was used as an example to analyzed the measures taken to prevent turbo-generator overspeed from the following aspects： main stop valve＇s movement test and tightness test,overspeed test of functions group and rotating speed control of turbine during load reiection. And applications of such functions in reality are presented.
