摘　　要：在剖析燃气蒸汽联合循环机组出力、能量转换和运行成本等特性的基础上,分别构建联合循环机组的模式模型和组件模型,提出以系统经济性最优为目标的计入循环机组的节能调度方法,并采用混合整数规划法求解。算例结果分析表明,建立的2种循环机组模型是正确有效的,所提节能调度方法能显著减小火电机组的出力波动和切负荷概率,提高系统的经济性和可靠性。The mode model and component model of gas-steam combined cycle unit are separately established based on its characteristics of power output,energy conversion and operating cost. The energysaving dispatch considering the combined cycle unit and taking the optimal economy as its objective is proposed and solved by the mixed integer programming. Case study shows that,two combined cycle unit models constructed are correct and effective,and the proposed energy-saving dispatch reduces significantly the power output fluctuation and the load shedding probability of thermal power unit ,enhancing the economy and reliability of power system.
