同步电机非线性参数的自适应辨识方法

An Adaptive Estimation Method for Nonlinear Parameters of Synchronous Machines

本文提出一种新的自适应参数辨识算法，以跟踪电机参数在动态过程中随工况呈非线性变化的轨迹。它利用电机实际运行时的输入输出数据，计及电机饱和、涡流效应，建立参数与工况因子之间的函数关系。该方法实际应用于大型汽轮发电机上，仿真计算与实测响应比较表明其有效性。

This paper proposes an adaptive nonlinear parameter estimation algorithm which uses on-line input/output data of generators in forms of functions with state arguments so as to include the effects of saturation, eddy currents, etc. Nonlinear parameters of a large turbogeneralor has been estimated by this method and computer simulation shous the parameters can be used in generators with good precision.
