摘　　要：采用回热Braydon循环的简化模型,确定了微型燃气轮机(微燃机)分布式能源系统(DES)各组件的热力学过程和火用损失的计算方法。针对同济大学某建筑内的微燃机分布式能源系统,进行了能量平衡和火用平衡计算,确认该系统比常规能源系统在能源利用率、火用效率方面具有更好的经济性。By using the simplified thermodynamic model of the regenerative Braydon cycle, the thermodynamic process and calculation method of exergy loss of each component for distributed energy system （DES） with micro - gas - turbine have been determined. Directing against a DES with micro - gas - turbine allocated in one building of Tongji University, energy balance and exergy balance have been calculated, it is believed that the said system is more economically favorable than other eonventiional energy system in aspects of energy utilization coefficient and exergy efficiency.
