摘　　要：在充分考虑静止自并励发电机锯齿波励磁电压对发电机暂态过程影响的基础上,提出利用积分技术和最小二乘辨识技术,对可测量的电压、电流、功率、频率等运行参数实施发电机Park模型参数时域辨识的方法。算例仿真表明,本文所提辨识方法是可行的。Taking the influence of the exciting voltage of the STW of the static self-excited synchronous generator on the transient process of the generator into full consideration, this paper introduces the application of the parameters of Park＇s model in identifying the time domains of such measurable operating parameters as voltage, current, power and frequency by means of the integration and the LS identification techniques. The simulation examples have proved the feasibility of the identification method.
