摘要：分析PMSM风力发电并网系统各组成部分工作机制,构建PMSM风力发电并网系统数学模型;基于分数阶和电网电压定向协同控制理论,探讨分数阶PI~λ控制器的设计与模型实现;以直流侧电压稳定、网侧单功率因数运行为目标,设计基于分数阶-协同控制的PMSM风电系统并网方案。在MATLAB/Simulink中建立PMSM风力发电并网系统仿真模型,结果表明,模型可以实现PMSM风电并网系统直流侧电压稳定的分数阶-协同控制。对比经典PI调节器,分数阶PI~λ控制效果更优,动态响应更快,直流侧电压更稳定,验证了所提方案的可行性和有效性。

Abstract：The working mechanism of each component of PMSM wind power grid-connected system was analyzed.The mathematical model of PMSM wind power grid-connected system was constructed.Based on fractional order and cooperative control theory, the design and model realization of fractional-order PIλcontroller were discussed.Taking the stable and network-side single power factor operation as the goal, a grid-based scheme for PMSM wind power system based on fractional-cooperative control was designed.The simulation model of PMSM wind power grid-connected system was established in MATLAB/Simulink.The results showed that the fractional-coordinate control of the DC-side voltage stability of PMSM wind power grid-connected system was realized.Compared with the classical PI regulator, the control effect of the PIλregulator was better.The response was faster and the DC side voltage was more stable.The feasibility and effectiveness of the proposed scheme were verified.
