摘要:
永磁同步发电机维护少、效率高、单机容量大，在风力发电系统中已得到广泛使用。分析永磁风力发电系统相关数学理论知识，在PSIM9.0环境下设计额定功率为3 kW的永磁风力发电系统模型，当风速信号发生阶跃变化时，观察机侧输出功率信号和并网侧直流电压信号变化情况，分析并调试系统仿真结果。最终结果显示，在不同风速情况下，风力发电系统各输出信号稳定，波形良好，与理论计算相符。为永磁风力发电系统进一步试验和研究提供了良好的基础和新的平台。

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.
