Abstract: Based on the modeling and simulating principles of process systems engineering, a steady-state thermodynamic system has been developed for simulation of a 300 MW pulverized coal-fired power plant, of which the basic principles and modeling approaches are described in detail. By varying the input parameters, loads and environmental conditions, operation performance of the power plant is simulated under different working conditions. Results show that the relative error of performance data between simulation and performance test is less than 2%. The thermodynamic parameters of mass and energy flow (including mass flow rate, temperature, pressure, specific enthalpy, specific entropy, etc.) and the main equipment running parameters (including isentropic efficiency of steam turbine and pump, terminal temperature difference of heater, heat conduction coefficient, etc.), which are obtained during simulation, may serve as a reference for actual operation and optimization, exergy analysis and thermo-economic analysis of coal-fired power plants.
