摘　　要：一般化的供热系统由燃料能释放与转移子系统、电量发生子系统、电能输配子系统、热量发生子系统、热量输配子系统和热用户子系统构成。利用“单耗分析理论”，分析了热电联产系统的能耗构成。以 ２００ ＭＷ供热机组构成的热电联产系统为对象，定量分析了环境温度、热网供（回）水参数、供热距离和供热抽汽参数对各子系统附加单耗和热电联产系统总能耗的影响，得出了一些有益于改善热电联产节能效果的结论。This paper introduces the concept of generalized heating system model. It consists of six sub-systems, that is, fuel energy delivery, power generation, power transmission & distribution, heat generation, heat transmission & distribution and end-users. The energy consumption of a CHP system is analyzed based on Consumption Rate Analysis Theory. The unit consumption varies with environment temperature, heating network water temperature, transmission distance. Pressure and temperature of extraction steam are also calculated.
