This article introduces the research and development and hardware configuration of the simulator for M701F ＂two-pull-one＂ gas-steam combined cycle units, expounds the technical features and software constitution of the simulation supporting system based on the general integrated CyberSim figure-mode-database simulation supporting platform and the mathematical models of the gas turbine. The complete working condition real-time simulation of the ＂two-pull-one＂ gas-steam combined cycle unit is realized with the simulation system. Test results show that theprecision of the gas turbine, heat recovery boiler, steam turbine and generator models meet the simulator design requirements and they have good static precision and dynamic response characteristics. The simulator can be used for the operation staff training and the analysis ＆ research of power plant control strategic optimization and operation mode.
