At present

most small index evaluation reports using the average of monthly evaluated indices can not meet the requirements of real-time monitoring and regulating for the main operation indices of power unit.Besides

the formation speed of the report is relatively low.Moreover

it is inconvenient for the history data inquiry and the unit whole course checking

and operation optimization.To solve these problems

a real-time evaluation report system was developed based on the plant-level supervisory information system(SIS) in power plant.Its practical application optimized the operation condition of the unit and enhanced the safety and economical efficiency.
