摘　　要：该文介绍了在三联供系统发电只能并网不能上网的地区,燃气冷热电三联供系统发电设备容量选择的一种方法。根据商业综合体项目负荷特性,通过全年逐时负荷计算及分析,首次通过解析不同负荷率下的小时数方程,按能源利用效率最高、全年高效率累计负荷最大的原则,确定发电设备的最优容量,并通过投资回报分析,验证此方法的可行性。This paper introduced one method to determine the power generation equipment for CCHP in the area where the power generation of CCHP can only be grid-connected but not output to the external grid. According to the load characteristics of a commercial complex, and based on the analysis of the hourly load of a commercial complex project throughout the year, the optimal volume of the power generation equipment was determined by analyzing the equation of hours under different load rates and taking the principles of the highest energy utilization efficiency and the highest efficient cumulative load. On this basis, the feasibility of this method was verified with the return on investment analysis.
