Abstract

It is urgent to ensure small signal stable operation of wind farm under variable wind speed conditions. However, the sub-synchronous resonant (SSR) stable wind speed range varies with the ratio of Type-III and Type-IV wind turbines in the hybrid wind farm grid-connected system (HWF-GCS) with series compensation lines. Firstly, the wind speed-frequency two-variable equivalent admittance model is established. Then, the influence of the ratio of Type-III and Type-IV wind turbines on the SSR stable wind speed range is analyzed by means of the amplitude phase contours plot criterion. The results show that the less the Type-III wind turbines in the HWF, the larger the stable wind speed range and the higher the stability margin, which can provide reference for the stability design in full wind speed range of actual hybrid wind farms. Simulation plat based on Matlab/Simulink is built to verify the correctness of the model and analysis results.

基于双变量导纳模型的混合风电场SSR稳定风速范围分析

如何保证风电场在变风速条件下的小信号稳定运行，已成为风电场的当务之急。然而，在串联补偿线路的混合风电场并网系统(HWF-GCS)中，亚同步谐振(SSR)稳定风速范围随iii型和iv型风力机比例的变化而变化。首先，建立了风速-频率两变量等效导纳模型;然后，利用幅相轮廓图判据分析了三、四型风力机比例对SSR稳定风速范围的影响。结果表明:风电场内iii型风力机越少，稳定风速范围越大，稳定裕度越高，可为实际混合风电场全风速范围内的稳定性设计提供参考。建立了基于Matlab/Simulink的仿真平台，验证了模型和分析结果的正确性。

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
