Taking the automatic plant startup and shutdown system(APS)of 9F combined cycle unit in Xiaoran Power Plant as an example,this paper analyzes the design idea,structure,break-point and implementation of APS.The research shows that APS can realize the one-click function of the unit from starting preparation work to starting gas turbine,steam turbine and generator with full load,which makes the important control loop full process,self-optimization of starting condi-tions,standardization of start and stop,automatic switching operation and intelligent parameter control,and effectively im-prove the safety and economy of the unit start and stop.
