永磁风电机组零电流矢量控制策略研究

Analysis of Permanent Magnet Synchronous Generator Wind Turbines Based on Zero Current Vector Control strategy

双PWM型永磁风电机组一般采用id=0的矢量控制策略。本文详细介绍了这种控制方法,在Matlab/Simulink平台搭建了并网永磁直驱风力发电系统模型。其中发电机组侧基于转子磁链定向,系统并网侧基于电网电压定向。对系统最大功率追踪时的运行特性进行了仿真试验。仿真结果验证了该控制策略的有效性和优缺点。

Dual PWM type PMSGs usually take id=0 as vector control strategy. This paper describes it and builts the model of directly-driven PMSG-WTs connecting to the grid by Matlab/Simulink. Generator side keeps the d axis equal to the rotor permanent flux and system to the grid side keeps the d axis equal to the grid voltage. The operating characteristics under MPPT are simulated. The results show the effectiveness and limitations ofit.
