摘要
针对装有双馈感应发电机(DFIG)风电场穿透功率增加带来的稳定性问题,从小干扰稳定性、电压稳定性、频率稳定性3个方面对国内外研究现状进行了分析和总结。综述了基于电力系统稳定器、柔性交流输电技术以及高压直流输电技术的双馈风电场并网系统的改善措施。最后对该领域的未来发展方向进行了展望,指出忽略风速波动和塔影效应,缺乏定量的评价标准对双馈风电场并网稳定性研究的影响。
The ride-through power increase of DFIG-based wind farm will impact the power system stability.Its research status quo at home and abroad is studied and summarized in three aspects：small signal stability,voltage stability,frequency stability.The improvement measures based on power system stabilizer,flexible AC transmission and HVDC transmission technology are reviewed.The future research in this field is prospected and the impact of following two facts on the research of grid-connection stability of DFIG-based wind farm is pointed out：neglect of wind speed fluctuation and tow shadow effect,lack of quantitative evaluation criteria.
