摘要
为提高S209FA燃气-蒸汽联合循环机组的运行安全性,针对机组近期出现的D11型汽轮机中压缸下缸温大幅下降、高压联合汽阀开启异常等现象,结合系统特点、设备特性和控制方式进行了深入分析,查明了导致异常的原因,积累了处置异常的经验。
In order to improve operation safety of S209FA gas-steam combined cycle units, the paper, in combination with system characteristics, equipment properties and control modes, analyzes temperature re- duction of lower part of medium-pressure cylinder and abnormity in opening combined high-pressure steam valve that occurred recently. The causes for abnormities are detected, which can be experience accumulated for abnormity handling
