随着可再生能源技术及其产业的快速发展,风力发电已成为当今最具发展前景的新型能源生产方式。然而在我国现实电网国情下,风电系统对真实电网环境的适应能力已构成现代风电技术进一步发展中必须认真考虑的重要因素。风电机组应能适应的电网环境主要包括电网电压骤变(骤降或骤升)、电网电压不平衡、电压谐波畸变等。对此,该文以双馈风电机组(doubly-fed induction generator,DFIG)为对象,通过对这些电网故障机理和现有风电控制技术不足的分析,提出采用谐振控制技术的解决方案,着重讨论了谐振控制技术的优势机理、工程实现中的主要考虑及其在增强DFIG电网适应性方面的应用方式。
隨著可再生能源技術及其產業的快速髮展,風力髮電已成為噹今最具髮展前景的新型能源生產方式。然而在我國現實電網國情下,風電繫統對真實電網環境的適應能力已構成現代風電技術進一步髮展中必鬚認真攷慮的重要因素。風電機組應能適應的電網環境主要包括電網電壓驟變(驟降或驟升)、電網電壓不平衡、電壓諧波畸變等。對此,該文以雙饋風電機組(doubly-fed induction generator,DFIG)為對象,通過對這些電網故障機理和現有風電控製技術不足的分析,提齣採用諧振控製技術的解決方案,著重討論瞭諧振控製技術的優勢機理、工程實現中的主要攷慮及其在增彊DFIG電網適應性方麵的應用方式。

With the rapid development of renewable energy technology and its industrial levels, the wind-power generation has become a production pattern of new energies with the most development prospects at present. Due to the actual grid condition of our country, the adaptability to the practical grid has also become the important factors to be seriously considered in the further development of modern wind-turbine technology. The adaptability to the grid for a wind-turbine includes grid voltage sag or swell, grid unbalance, grid voltage harmonic distortion, etc. About this, aimed at doubly-fed induction generator (DFIG) and via analyzing the mechanisms of grid faults and the deficiency of modern wind-power technique, the paper proposed a solution scheme of adopting resonant control with the emphasizing on the discussion about the advantage of resonant control, the consideration of engineering realization and the application on enhancing the adoptability of DFIG to the grid.
