摘要

本文建立了并网永磁同步发电机(GFM-PMSG)风力发电机组机侧变换器(MSC)的小信号模型，分析了其直流阻抗。结果表明，MSC对GFM-PMSG风力发电机交流阻抗模型影响较小。这一发现表明，配备GFM控制的电网侧变流器动力学在GFM- pmsg风电机组与电网的动态相互作用中起着至关重要的作用。通过非线性时域仿真验证了理论分析的正确性。最后，通过实验验证了理论结论。

Impact of Machine-Side Converter Dynamics on AC Impedance of Grid-Forming PMSG Wind Turbines

This paper builds the small-signal model and analyzes the dc impedance of machine-side converter (MSC) for grid-forming permanent synchronous generator (GFM-PMSG) wind turbines. It is revealed that MSC has little impact on the ac impedance model of GFM-PMSG wind turbines. This finding implies that the grid-side converter dynamics, which is equipped with the GFM control, plays a critical role in the dynamic interactions between GFM-PMSG wind turbines and the power grid. The nonlinear time-domain simulations are carried out to corroborate the theoretical analysis. Finally, experimental tests are carried out to corroborate the theoretical findings.
