Establishment Of The Loss Differential Calculation Model Of The Important Parameters In The Thermo-Economic Analysis For Power Plant

A rapid,accurate and complete analysis of unit economic performance is necessary for individual power plant to improve its competition in market.In the view of an existing prblom which exists in the Energy-loss analysis:the determination of the exhaust enthalpy,two methods are presented which are true of calculating the the exhaust enthalpy.Based on studying the relationship between important parameters variation and coal consumption,which is significant in operation of thermal power generating units,the analysis of controllable parameter related to boiler,turbine,reheating system and condensers and units economic dispatching etc are given and the math models are developed in this paper,offering a basic way to the adjustment of controllable parameter variation and optimum economy in whole units.Real-time Performance Evaluation System for Thermal Power Plants is introduced and a conception about building an energy-loss differential analysis system based on it is raised.
