摘　　要：风力发电系统所捕获的风能随风速的改变而变化。实现最大风能捕获是现代变速恒频风力发电系统的主要目标之一。本文在最优转矩控制策略的基础上,设计了增益调度比例积分控制来实现永磁同步风力发电系统的最大风能捕获。通过控制永磁同步发电机的定子电流跟踪其参考值,从而实现最大风能捕获。所采用的的控制策略不需要知道风速,可以省去风速仪装置。本文将通过Matlab/Simulink仿真测试来验证所提出控制策略的可行性和有效性。The wind energy captured by a wind power system changes with wind speed.Achieving maximum wind energy capture is one of the main goals for modern variable-speed constant-frequency wind power generation system.Based on the optimal torque control strategy,the gain-scheduling proportional-integral control is designed to achieve the maximum wind energy capture of permanent magnet synchronous wind power generation system.The maximum wind energy is captured by controlling the stator currents of the permanent magnet synchronous generator to track their reference values,respectively.The adopted control strategy does not need to know wind speed,which can eliminate the anemometer device.This paper will verify the feasibility and effectiveness of the proposed control strategy through Matlab/Simulink simulation test.
