摘要

风电机组变流器是变速恒频风电机组的核心部件，变流器电网侧滤波器在保证良好并网特性的同时也给系统带来了谐振稳定性问题。基于风电机组变流器网侧滤波器动态特性进行分析，揭示了风电机组谐振机理，提出了虚拟变阻尼谐振抑制策略。在MATLAB/Simulink中建立了2.0 MW直驱型永磁同步风电机组仿真模型，实现了风电机组谐振与抑制的全过程仿真。利用电网谐波发生模拟装置，首次在2.0 MW永磁直驱风电机组上进行了机组谐振与抑制现场试验。仿真与现场试验证明了理论分析的正确性与谐振抑制策略的有效性，对实际运行时风电机组的谐振问题和风电机组变流器设计具有指导意义。

Abstract

The wind turbine converter (WTC) is one of the key components for wind turbine. The filter of the grid-side converter

while ensuring good integrating characteristics

brings about resonant stability issues. For the actual resonance problems encountered in the development of wind power

the natural resonance point of system is confirmed and the resonant mechanism revealed by analyzing the dynamic characteristics of the grid-side converter filter. And a virtual variable damping control strategy is proposed to suppress the wind turbine resonance. A 2.0 MW permanent magnet synchronous generator wind turbine (PMSG-WT) is modeled in MATLAB/Simulink

and the resonant and suppressing process of PMSG-WT is emulated by simulation. A field test is carried out on the 2.0 MW PMSG-WT by grid harmonic generation equipment for the first time. The correctness of theoretical analysis and effectiveness of the resonance suppressing strategy is supported by simulation and experimental results

which is of guiding significance for resonance adjustment of running wind turbine and wind turbine converter design.
