摘　　要：为优选风电-抽凝机组耦合系统供暖方案,以350 MW抽凝机组为例,通过利用Ebsilon软件构建抽凝机组仿真模型获得了主蒸汽消耗量与电热负荷关系,分别计算了增设储热罐、增设蓄热电锅炉、增设电热泵和储热罐耦合装置、增设吸收式热泵4种供暖方案和原抽汽供暖方案下消纳风电容量、主蒸汽消耗量及热负荷扩大比例等参数。结果表明:与原抽汽供暖方案相比,其余4种供暖方案进一步提高机组消纳风电能力受约束限制情况影响;降低主蒸汽消耗量由大到小的顺序是增设电热泵和储热罐耦合装置、增设蓄热电锅炉、吸收式热泵和增设储热罐;热负荷扩大比例由大到小的顺序是增设电热泵和储热罐耦合装置、增设蓄热电锅炉、增设储热罐和增设吸收式热泵。In order to optimize the heat supply scheme for coupled system of wind power and condensing units,the simulation model of a 350 MW extraction condensing unit was established by Ebsilon software,and the functional relationship between the main steam consumption of the condensing unit and the electric/heat load was obtained.Parameters such as the absorbing wind power capacity,main steam consumption and heat load expansion ratio under the original steam extraction heating scheme and other four heating schemes(including adding heat storage tank,adding heat storage electric boiler,adding electric heat pump and heat storage tank coupling devices,and adding absorption heat pump)were calculated.The results show that,compared with the original extraction steam heating scheme,the other four heating schemes can further improve the condensing unit’s capacity that be affected by specific limiting factors to absorb wind power.The order of reducing the consumption of main steam from large to small is,adding the coupling device of electric heat pump and heat storage tank,adding the heat storage electric boiler,adding the absorption heat pump,and adding the heat storage tank.The order of the heat load expansion ratio from large to small is,adding the coupling device of electric heat pump and heat storage tank,adding the heat storage electric boiler,adding the heat storage tank,and adding the absorption heat pump.
