摘　　要：大规模风电场并网会出现频率偏移、弱馈性和高谐波等暂态稳定问题,对系统的安全运行造成影响。因此,很有必要研究大规模风电场并网暂态保护技术。对大规模风电场的并网技术和暂态保护技术进行了全面评述,分析了每种并网技术的拓扑结构,对比了基于双馈异步风力发电机、直驱永磁同步发电机、传统同步电源系统3种发电系统的故障特性,同时阐述了陆上风电场和海上风电场暂态量保护的研究现状,最后对未来大规模风电场的暂态保护的发展提出了展望,可为未来风电场并网的研究提供参考。The integration of large-scale wind farms will lead to transient stability problems,such as frequency offset,weak feedback and high harmonics,and affect the safe operation of the system.Therefore,research of transient protection technology for large-scale wind farm integration is an urgent requirement.A comprehensive review about grid connection technology and the transient protection technology for large-scale wind farms is carried out.The topology structure of each integration technology is carefully analyzed.Besides,the fault characteristics of three power systems,including permanent magnet synchronous generator,doubly fed induction generator,and traditional synchronous power system are compared and the current research status of transient based protection of onshore and offshore wind farms is illustrated.Finally,perspectives are outlined for future development of relay protection technology in large-scale wind farms,which provides a significant reference for the research of future wind farm integration.
