摘　　要：传统循环水泵运行优化以汽轮机最大净出力为基准,该方法忽略了电网调度模式对机组实际出力的控制,通过深入分析机组实际运行状态,综合考虑煤价和电价对循环水泵运行优化的影响,提出基于煤电经济值最优的优化理论,并对某660MW机组进行实例分析。对于我国主要以机组发电量为控制基准的电网调度模式,由煤电经济值最优法确定循环水泵最优运行方式能更真实、最大限度地提高机组实际经济收益。The traditional water circulating pump operation optimization is based on the maximum net capacity of the steam turbine. This method neglects the influence of the grid scheduling model on unit output. This paper proposed the optimization theory based on coal, electricity economic value through in-depth analysis of the actual operation of the unit state, considering the influence of the price of coal and electricity on water circulating pump operation optimization. This method that based on the economic value of coal and electricity optimality can furthest, more real improve the unit actual economic benefits for our country that grid scheduling model is based on the unit output.
