Test research of the heat load economic dispatch under electricity load in cogeneration units

建立了热电联产机组在定电负荷下的热负荷经济调度技术方案。首先通过试验获取参与调度的每台机组供热煤耗特性曲线,再建立热负荷经济调度数学模型,并选择合理的优化方法对模型进行求解,最后计算得出优化分配结果。通过某热电厂2台300MW供热机组的试验及实例计算,得出了某热电厂在定电负荷情况下的供热煤耗特性,以及在定电负荷情况下的热负荷最优分配。

The heat load economic dispatch technology solutions under electricity in cogeneration units is established. First of all,through the test to get the heating coal consumption characteristic curve of each heating unit,then establishing the heat load economic dispatch mathematical model,and selecting the reasonable optimization method to solve the model,finally calculate optimal allocation results. Through the test and the calculation of a thermal power plant with two 300MW heating units,the heating coal consumption characteristics and the heat load optimal distriution under electricity load are obtained.
