| 摘 要： | 对于具有并网变流器的风电系统,本文提出了一种基于负载电流前馈的网侧变流器矢量控制方法。与传统方法相比,该方法可提高风电系统在最大风能捕获过程中的暂态稳定性和抑制电网电压波动对直流母线电压所造成的影响。本文以双馈发电机型风电系统为例进行了理论分析和仿真实验,结果验证了所提方法的正确性和有效性。

| Abstract: | For wind power system with back-to-back converters,this paper proposes a vector control method with feed-forward load current compensation of the grid-side converter. Compared with traditional methods,the proposed method can not only improve the transient stability of wind power system in the process of maximum power point tracking(MPPT) but also reduce the influence on the DC-link voltage caused by fluctuation of the grid voltage.Theoretical derivation and detailed simulation studies were performed on the ... |
