摘　　要：针对目前分布式能源系统能量利用评价方法、指标的局限性,结合某燃气-蒸汽联合循环系统,采用等效电耗法对分布式能源系统能量利用进行了分析。结果表明:从可比性能系数角度而言,分布式能源系统供冷/供热环节的节能性优于传统方式;从供冷/供热的等效电耗而言,利用分布式能源系统降低吸收式制冷机抽汽温度是提高系统性能的有效手段。该研究结果对分布式能源的节能性以及优化运行提供了参考。According to the limitations of indicators in the current energy utilization performance evaluation method for the distributed energy system, the energy utilization in the distributed energy system was inves- tigated by adopting the equivalent energy consumption analysis method,taking a gas-steam combined cycle system as the research object. The results show that,from the aspect of the comparable coefficient of per- formance, the energy saving ability of the cooling/heating link of the distributed energy system is better than that of the conventional one. From the aspect of the equivalent power consumption of the cooling/ heating link,in the distributed energy system, reducing the extraction steam temperature for the absorption refrigerating machine is an effective way to improve the system performance.
