针对传统太阳能燃气联合循环机组无法适应当前电–热综合能源系统发展趋势的问题,该文建立太阳能燃气联合循环热电联产机组的稳态模型,分析燃气联合循环机组配置太阳能及储热设备前后运行特性及调峰能力的变化情况;进而构建机组经济性模型并进行典型日调度分析。结果表明:太阳能的输入可以增大原机组的热电可行域,增强机组的调峰能力;太阳能燃气联合循环热电联产机组减少了化石燃料的消耗,具有良好的经济效益和环境效益。

Aiming at the problem that the traditional integrated solar combined cycle system cannot adapt to the development of integrated energy system, an analysis model of integrated solar cycle cogeneration system was established. The variation of operation characteristics and peak regulation capacity of gas combined cycle unit with solar energy was analyzed, and the unit economic model was established and the typical daily scheduling analysis was carried out in this paper. The results show that: By analyzing the thermoelectric characteristics of the system, it is found that the input of solar energy can improve the thermoelectric load characteristic of the original unit so that the thermoelectric decoupling to a certain extent is promoted and increases the peak-regulating capacity of the system. Based on the analysis of the economy of the system, the solar gas combined cycle cogeneration unit reduces the consumption of fossil fuels, with good economic and environment benefits.
