摘　　要：对设备投资较高的微型燃气轮机(微燃机)分布式能源系统,其基于动态能耗的分析非常重要。通过建立微燃机热力数学模型,预测并分析了不同环境温度下微燃机的性能参数变化;在该系统现有配置基础上尝试增加了补燃配置,分别作了动态能耗计算,并与常规空调系统相比较进行了运行经济性分析。分析表明,微燃机分布式能源系统须在适当的系统配置及合理的工况下运行。Owing to higher investment of distributed energy system （DES） based on micro- gas- turbines,the dynamic energy consumption analysis is especially important. Through establishment of thermal mathematic model of micro- gas- turbine, the variation of performance parameters for microgas- turbines has been predicted and analysed under different ambient temperature. A supplementary fuel layout is attempted to be added into the existing configuration of said system, the dynamic energy consumption being calculated respectively, and the economic analysis in operation being carried out through comparison with conventional air -conditioning system. Analysis shows that the DES based on micro - gas - turbines has to be operated under appropriate system configuration and reasonable operating conditions.
