燃气冷热电三联供系统发电设备容量选择

摘要

Presents conventional ways to determine the generation capacity. According to the annual hourly load, obtains the generation capacity with a project in Shijiazhuang by the two methods of fixing power based on cooling/heating load and fixing power based on electricity load. The results show that the annual hourly load is important not only for determining the generation capacity, but also for forecasting the operating cost; appropriate power-on hours are the key to determine the generation capacity.%介绍了燃气冷热电三联供系统发电设备容量确定的常规思路,结合石家庄某项目,基于全年逐时负荷,按以热定电与以电定热的思路分别确定了发电设备容量.通过分析发现:全年逐时动态冷热负荷的分析十分重要,不仅是确定设备容量的需要,也是分析运行成本的需要;确定发电机容量时需要合理选定发电机的开机时间.
