摘要
研究双馈型风力发电系统变流器控制参数对振荡模态的影响。在MATLAB/Simulink中建立系统详细的小信号模型,利用特征值分析和相关因子分析,对机网相互作用振荡模态进行辨识和分类。通过改变变流器控制参数,研究振荡模态的变化特性。最后,在MATLAB/Simulink上进行仿真验证。研究表明,优化变流器控制参数,可有效抑制振荡。
The effects of converter control parameters of DFIG wind generation system on the oscillation modes were studied. A complete small signal model in MATI,AB/Simulink was proposed. By using eigenvalue and participation factors analysis, the oscillation modes were discovered and classified. By altering the parameters of converter, the changes of oscillation modes were studied. Finally, simulation was done on the MATLAB/ Simulink. The research showed that the oscillation could be suppressed by optimizing the control parameters of converter.
