摘　　要：采用EBSILON软件建立2台二次调节抽汽式汽轮机联机运行仿真模型,采用遗传算法对2台汽轮机的热电负荷进行优化分配。将平均分配方案作为比较对象,分析优化分配方案在不同工况下的优化分配结果。优化分配方案的锅炉产汽量低于平均分配方案,尤其是热负荷较大的供暖期工况,锅炉产汽量减少27.52 t/h。优化分配方案的分配结果有利于热电厂节能运行。The EBSILON software was used to establish a simulation model for the online operation of two secondary regulated extractive steam turbines,and the genetic algorithm was used to optimize the distribution of the thermoelectric load of the two steam turbines.Taking the average distribution scheme as the comparison object,the optimized distribution results of the optimized distribution scheme under different working conditions are analyzed.The boiler steam production of the optimized distribution scheme is lower than that of the average distribution scheme,especially during the heating period with large heat load,the boiler steam production is reduced by 27.52 t/h.The distribution results of the optimized distribution scheme are beneficial to the energy-saving operation of the thermal power plant.
