摘　　要：针对供热机组的抽汽方式和供热形式各不相同,供热机组以热定电的运行方式影响着机组的经济性和电网的负荷调度的问题,给出了不同容量、不同形式供热机组供热运行中带电负荷的限制因素。以几个电厂的供热机组为例,给出了机组的最低供热电负荷实测方法,可为电厂运行和调度提供参考。Pumping mode and heating mode are various for heat supply unit, operational mode ofheat supply unit can deeply affect its efficiency and peak regulation of power network as powerload of heat supply unit depends on its heat load. According to minimal load test limiting factors ofoperation at power load are obtained for heat supply unit with different capacity and types. The min?imal load of the unit is given by minimal load test in several heat supply units, which provides ref?erences for the operation of the power plant and peak regulation.
