摘　　要：为实现燃气-蒸汽联合循环机组一次调频能力的分析与优化,构建了能够考虑燃气轮机、余热锅炉、汽轮发电机组等主设备出力调节速率限制因素,并且可以兼顾机组运行状态分析的通用燃气-蒸汽联合循环机组一次调频能力分析模型。对不同发电负荷下联合循环机组一次调频能力及其影响因素进行了分析,并提出了通过机组一次调频响应滞后时间补偿、实际转速不等率补偿两种方法来实现机组一次调频能力的优化。In order to analyze and optimize the primary frequency modulation capability of the gas-steam combined cycle unit,a general primary frequency modulation capability analysis model of gas-steam combined cycle unit was constructed,which can include the output regulation rate of main equipment such as gas turbine,waste heat boiler and turbo generator.The primary frequency modulation capability and its influencing factors of the combined cycle unit under different power generation loads were analyzed.Two optimization methods for primary frequency modulation capability of the unit are proposed,which are the primary frequency response lag with time compensation,and the actual speed unequal rate optimization.
