基于模糊PI控制的双馈风力发电机空载并网控制策略

No-load grid connection control strategy based on fuzzy PI control for the doubly-fed induction generator

针对双馈式变速恒频风力发电机传统并网方式的缺陷,提出了一种基于定子磁链定向的双馈电机控制理论的模糊PI空载并网控制策略。通过Matlab/Simulink仿真平台搭建了空载并网控制仿真模型,并与传统PI控制策略进行了仿真比较。仿真结果表明该控制策略能达到变速情况下双馈风力发电机无冲击并网的目的,具有良好的动态品质,验证了该控制策略的正确性和有效性。

For the lack of traditional doubly-fed variable soeed constant freauency （VSCF） wind turbine gridconnection, a no-load arid connection fuzzy PI control strategy is proposed based on the stator flux orientation control technioue. The no-load arid connection control strategy model is established through Matlab/Simnlink simulation nlafform, and comnared with traditional PI control strategy. The simulation results show that the control strategy can achieve the nuroose of no imnact on the arid under variable soeed, which has a good dynamic aualitv. The correctness and effectiveness of this control strategy are also verified.
