基于谐波状态空间的永磁同步发电机风力发电系统建模及频率耦合分析
Modeling and Frequency Coupling Analysis of PMSG Wind Power Generation System Based on Harmonic State Space
摘要
Abstract
The proposal of"carbon neutral"and"carbon peak"goals,along with the implementation of policies such as low-carbon energy transformation,lead to an remarkable increase in the integration of new energy sources,thereby transforming the power system into a electronic one.The high power electronic power system is susceptible to frequency coupling,harmonic resonance and other issues that may result in system instability when severe.In view of this,in this paper the first step in-volves constructing a small signal model of wind turbine grid-connected system in closed-loop mode,based on the harmonic state space theory.Then,the harmonic state space matrix of permanent magnet synchronous wind power generation system was derived,followed by a successful establishment and qualit-ative analysis on the system frequency coupling relationship.The accuracy of the model is ultimately validated through a comparison between the simulation model results and the math-ematical model results.关键词
