# 永磁同步风力发电机组建模和控制策略研究Modeling and Control Research of Direct-Drive Permanent Magnet Synchronous Wind Power Generator

Abstract: Permanent magnet synchronous generator (PMSG), with less maintenance, high efficiency, large unit capacity, has been widely used in wind power generation system (WECS). This paper analyzes the mathematical theory knowledge of the permanent magnet synchronous wind power system, and designs a rated power of 3 kW permanent magnet wind power system model under PSIM9.0 environment. When the wind speed signal generation has step change, we observe the change status of the output power signal on the machine side and the DC voltage signal changes on the grid side, analyze and debug system simulation results. The final result shows that, under different wind conditions, the output signal of wind power system is stable and waveform is good, which are consistent with the theoretical calculation. It provides a good foundation and new platform for further testing and research of permanent magnet wind power system.
