摘　　要：基于叶素理论建立了风力发电机组空载状况下的数学物理模型,以攻角为控制对象设计控制器,在此基础上,以Matlab/Simulink为工具,建立了系统仿真模型,采用"试凑法"选择PI控制器的参数,通过设定风速分析了风力发电机组的运行特性,仿真结果验证了理论分析的正确性。该研究对控制器的设计具有参考价值。Based on the blade element theory, a wind power generator no-load mathematical physical model was established and a PI controller aiming at angle of attack was designed in this paper. A system simulation model was set up in Matlab/Simulink and PI controller parameters were chosen according to the ＂trail-and-error＂ method. The operating performance of wind power generator was analyzed by stepping representation wind speed, the simulation results prove the correctness of the theory analysis. In addition, the study also has reference value on the controller design.
