基于随机子空间的同步发电机参数辨识方法
Method of synchronous generator parameter identification based on stochastic subspace identification
摘要
Abstract
From the point of view of modeling synchronous generator, in traditional synchronous generators parameter identification method existing low anti-interference ability, precision of the shortcomings of the poor, and put forward the stochastic subspace identification of synchronous generators parameter identification method. Will be collected to the stator current signal, the matrix form Hankel matrix QR decomposition and characteristic value decomposition (SVD), get the characteristic value of the system matrix, and then get in the stator current DC component and frequency components of the attenuation coefficient, through the least squares fitting all the components of the amplitude and phase, so as to realize the parameter identification of synchronous generator. Finally ,the simulation test the efficiency of this method.关键词
