摘　　要：对江苏沙洲电厂1000 MW超超临界燃煤机组的一次调频控制策略进行了分析,并且在对控制对象动态特性分析的基础上进行了控制参数的试验整定,通过机组的一次调频试验,表明将转速不等率设计函数直接用于计算一次调频负荷指令,并将其和功率设定值及实际功率一起作为汽机主控PID的输入量计算综合阀位,能够满足一次调频导则参数指标的要求。The control strategy of the primary frequency modulation about 1000 MW ultra-supercritical coal-fired unit in the Jiangsu Shazhou Power Plant is analyzed,experimentally tunes the parameter on the basis of the analysis of dynamic characteristic of controlled object,the test about the primary frequency modulation shows that it can satisfy the requirements of the guideline of primary frequency parameters by directly calculating primary frequency modulation load instruction with speed governing droop design function,and calculating integrated valve position by using primary frequency modulation load instruction,power set point and actual power as the input of the turbine master control PID.
