MW级双馈风力发电系统控制策略研究

Modeling and Simulation of AC Excited VSCF in Wind Power System

介绍了双馈变速恒频(VSCF)风力发电系统运行的基本原理及发电机的定子磁链定向矢量控制技术。在此基础上,以MATLAB/Simulink为工具,建立了系统仿真模型,进行了发电机有功、无功功率独立调节、最大风能捕获运行等工况的仿真研究。仿真结果表明理论分析正确,对系统的试验研究具有一定的理论指导意义。

The principle of AC excited VSCF in wind power systems and the vector control technique oriented by the stator flux of the generator was introduced. The paper made a simulation model based on Matlab/Simulink,and did simulation in several conditions such as independently modulation of the active and reactive power and capture of the maximum wind power. The simulation results show that the analysis is right and have very important guidance significance on experimental systems.
