Vector Control Strategy for Permanent Magnet Direct-driven Wind Generation System

本文以永磁直驱风力发电矢量控制系统为研究对象。在详细推导永磁发电机数学模型基础上,采用电流矢量解耦独立控制永磁发电机输出电流的有功和无功分量,实现无静差控制。同时通过最佳叶尖速比法最大风能跟踪方法,获得最大风能利用系数,实现系统的最大效率运行。仿真结果表明所采用控制策略的有效性。

The vector control strategy for for Permanent Magnet Direct-driven Wind Generation System was studied in this paper. To achieve static error-free control of permanent magnet by decoupling the output current vector of the active and reactive component based on the mathematical mode of permanent magnet synchronous generator. Meanwhile, maximum power utilization factor is obtaining by the optimal tip speed ratio method. This method enables wind power system to run at the maximum efficiency. The simulation result show that the proposed control strategies is effective.
