Abstract: Thermal power plants constitute the largest proportion of installed capability in global power generation system and consume large quantities of coal. Achieving optimal operation of thermal power units, improving the efficiency and reducing the coal consumption is of great significance for the reduction of greenhouse gas and pollutants emissions. Modelling and simulation is the base of optimal operation and control in thermal power unit. In this paper, research results of modelling and simulation of thermal power units are reviewed. Firstly, several common models which are used for researches of thermal power control systems are analysed, including simplified turbine and furnace models for unit coordinated control system (CCS) as well as local equipment models. Then the system structure, function and application of thermal power stimulated simulator are described. Finally, the structure and function of digital power plant is introduced. The challenges of modelling and simulation of thermal power plant researches in the future are discussed.
