摘　　要：以某330MW热电联产机组为例,对于集成吸收式热泵的热电解耦性能及能耗特性展开了理论研究。结果表明:耦合吸收式热泵扩大了热电联产机组的安全运行范围,提高了热电联产机组的最大热电比,降低了热电联产机组的最低电负荷率。当供热量为300MW时,热电联产机组电功率上调与下调能力分别增加40.53%、84.76%,最低电负荷率降低16.24%。当发电量为200MW时,其最大热电比提高了0.56。最后,对集成吸收式热泵的节能潜力进行了计算和分析。In this study,the decoupling performance and energy consumption characteristics of the combined heat and power(CHP)plant integrated with absorption heat pump are studied with a 330MW reference CHP plant.Results show that the safe operation range of the CHP plant is expanded.The maximum heat-electric ratio is increased and the minimum electric load rate is decreased.The electricity up-regulation and down-regulation capacity are increased by 40.53%and 84.76%,respectively.The lowest electric load rate is reduced by 16.24%when the heat load is 300MW.The maximum heat-electric ratio is increased by 0.56 when the electric load is 200MW.At last,the energy saving potential of absorption heat pump is analyzed.
