摘要
在建立了异步电动机电力负荷模型的基础上，利用最小二乘法、复合变量法、卡尔曼滤波法在线辨识电力负荷特性．结果表明，当电力系统电压频率发生变化时，辨识的有功模型特性与异步电动机特性较为一致，辨识的无功模型精度较差，四阶模型优于三阶模型．
This paper presents the simulation results of the power load characteristics of noline identification with the RLS (Recursive Least Square) method, the Ⅳ (Instrumental Variable) method, and the KF(Kalman Filiter) method. When the System voltage and frequency are modified, the identification of the active power model characteristics is simular to that of the characteristics of the motor. But the identification of reactive power model characteristics is not as good. The identification model rank 4 is better than rank 3.
