Abstract:Due to the thermal power plant unit cold start requires long time,procedure is complicated, and surveillance and grating is difficult,a method of “break down composite” was indicate and applied to develop automatic grating system for thermal power plant.This grating system is objective and fair,is able to reflect the proficiency of an operator.The system developed has been applied on simulator,and has broad application foreground.

Keywords:thermal power unit, simulator, grating system, cold start
