Abstract:

Abstract:The sliding parameter shutdown could reduce the body temperature of cylinder quickly, which is benefit for the rapid maintenance of turbine body. This paper introduced the typical sliding parameter shutdown processes of the 2×1000MW ultra supercritical units of Guangdong Yudean Jinghai Power Generation Company Limited.Through analyzing the process control,parameter variation and appeared exceptions of sliding parameter shutdown of No.4 unit,this paper summarized the operation mentality, controlling points and announcements of sliding parameter shutdown of 1000MW unit,and which provided a reference for the slidingparameter shutdown of same type unit.
