摘要
通过区域燃气冷热电三联供项目特点的分析,提出区域三联供项目与传统热电联产项目的差异性,不能直接套用"以热定电"、"以电定热"等发电容量配置原则。同时,探讨区域集中供能发电机组容量配置方法。并以上海某区域供能项目为例,对不同大小发电机组容量及不同并网方式进行分析,综合发电机组年利用小时数、发电自用比例及投资等因素给出项目发电容量配置。
Analyzes the characteristics of regional gas combined cooling heating and power（CCHP）projects, and the differences between CCHP projects and traditional combined heat and power generation（CHP） projects. Points out that＂determining power by heating load＂, ＂determining heating load by power＂principles is not appropriate for CCHP projects.Meanwhile, puts forward the method of determining power capacity in the regional CCHP. Takes a regional energy supply project in Shanghai as an example, analyzes the system performance in different power capacities. Gives the power capacity considering annual power generation hours, self-occupied power to total generating power ratio and the investment.
