Parameter Identification of Permanent Magnet Synchronous Wind Power Generator Based on Improved SVD-Prony Algorithm
摘要
Abstract
It is very important to establish an accurate model of permanent magnet synchronous wind power generator for analyzing and controlling the security and stability of power system,but the generator parameters are difficult to determine accurately.As the fact that current fundamental component and harmonic component of three-phase short-circuit current occurred in electric power system are determined by generator parameters,a parameter identification method of permanent magnet synchronous wind power generator based on improved SVD-Prony algorithm is proposed.Through the case studies of two types of examples,it is proved that the proposed parameter identification method of permanent magnet synchronous wind power generator is feasible,the identification model is effective and the parameters are accurate.关键词
