【摘要】 一次调频机组的调差系数宜取得一致,调差系数不一致对系统的稳定性、经济运行不利。对HVDC辅助一次调频控制器(APFR)的比例系数的取值进行了探讨,分析了不同比例系数的APFR控制器的动态特性和时域仿真结果,APFR控制器的比例系数宜在适中的范围内取值,而等调差系数法确定的比例系数在此范围之内。更多还原

【Abstract】 The primary frequency regulator coefficients of generators are always the same for the benefits of system stability and economical operation.The proportional coefficient of the Auxiliary Primary Frequency Regulator(APFR) is discussed.The analysis of the dynamic characteristics and the time domain simulation of APFR with different proportional coefficients show that the proportional coefficient of APFR should be in an appropriate range and the proportional coefficient determined by the equal regulation coefficient method is just within this range.更多还原
