摘　　要：利用某联合循环电厂450 MW机组在性能保证工况温控模式下的设计参数,以热力循环模拟软件EBSILON为平台,搭建燃气-蒸汽联合循环机组模型。同时,改变压气机入口处的环境参数进行仿真,分析和研究不同环境参数下联合循环系统出力和热效率的变化情况。通过仿真结果与理论分析及厂家修正曲线的对比,验证了该模型的有效性;该模型可用于联合循环机组优化运行研究,指导燃气电厂的经济运行。Using the design parameters of a combined cycle power plant 450 MW unit in performance guarantee condition of temperature control mode,based on thermodynamic cycle simulation software EBSILON platform,sets up the gas and steam combined cycle unit model. At the same time,simulated by changing the environment parameters at the entrance of compressor. Analyzed and studied the changes of the output and thermal efficiency of the combined cycle system under different environment parameters. The simulation results were compared with theoretical analysis and factory correction curve to verify the effectiveness of this model. This model can be used in the study of combined cycle unit optimizing operation,and it can guide the economic operation of gas plants.
