摘　　要：以N600-16.67/537/537机组为例,建立供电煤耗率最大为目标函数,通过计算电厂热耗量和循环水泵耗功,确定最佳运行参数。结果表明:随着机组负荷或冷却水温度的增加,最佳初压和排汽压力随之升高;当冷却水温度高于25℃时,对机组运行参数影响较为突出。通过优化运行参数,能为机组经济运行提供一定参考。Taking N600 -16. 67/537/537 unit as an example, coal consumption rate of power supply is designed as an objative function in this study, the optimum operating parameters were the determined by calculating the heat consumption of power plant and power consumption of circulating water pump. The results show that optimal initial pressure and exhaust pressure rise with the increase of unit load or cooling water temperature. Cooling water tem- perature would have greater influences on operational parameters when it is above 25 ℃. Consequently, this inves- tigation can provide guidance for economic operation of units by the optimization of operational parameters.
