摘　　要：为提高供热汽轮机电出力调节能力提供指导,基于优化的变工况热力计算方法建立供热汽轮机电出力的快速计算模型。耦合热负荷动态计算模型建立灵活调节潜力挖掘评价方法,实现出力的实时监测和运行指导。结果表明:基于优化的变工况计算方法可实现供热汽轮机电出力的快速计算,具有较好的准确性。通过对机组出力评估可以实现0~116MW的升负荷运行和0~82MW的降负荷运行。供热机组受季节影响较大,春季和秋季的供热负荷较低,可调容量较大。冬季的供热负荷较大,可调容量减少。The proportion of new energy entering the grid is constantly increasing.Based on an optimized variable condition thermal calculation method,a fast calculation model for the output of heating turbine electromechanical systems was established,which provided guidance for improving the output regulation ability of heating turbine electromechanical systems.A flexible adjustment potential mining and evaluation method using a coupled heat load dynamic calculation model was establish to achieve real-time monitoring and operational guidance of output.The results show that the optimized method of off-design condition calculation can achieve fast calculation of the electromechanical output of cogeneration steam turbines,which has the good accuracy.By evaluating the output of the unit,it is possible to achieve load up operation of 0-116MW and load down operation of 0-82MW.Cogeneration steam turbines are greatly affected by the season,with low heating loads in spring and autumn and large adjustable capacity.The heating load in winter is relatively high,and the adjustable capacity is reduced.
