摘要
分析直驱永磁风力发电系统各组成部分的关系,建立永磁同步电机(permanent magnet synchronous motor, PMSM)风力发电系统各组成部分的数学模型;基于最佳叶尖速比的最大功率点跟踪策略和非线性无源控制理论,设计基于无源控制的最大功率点跟踪方案;在Simulink中搭建PMSM风电系统各组成部分和控制系统的仿真模型并进行仿真试验。结果表明:非线性无源控制控制器能够实现最大风能功率的跟踪;控制效果良好,风能利用系数C_p稳定运行在0.48左右。这验证了所提方案的可行性和有效性。
The relationships among the components of the direct-drive permanent magnet wind power generation system were analyzed,and the mathematical model of each component of the PMSM wind power generation system was established.The maximum power point tracking strategy and nonlinear passive control theory based on the optimal tip speed ratio were designed.Based on the maximum power point tracking scheme of passive control,the simulation model of each component and control system of PMSM wind power system were built in Simulink.The results showed that the nonlinear passive control controller could achieve the maximum wind power tracking.The control effects were good,and the wind energy utilization coefficient C_p was stable at around 0.48.The feasibility and effectiveness of the proposed scheme were verified.
