摘　　要：采用柔性直流送出是未来大规模远距离风电并网的主流趋势。随着相工程的不断投运,风电场-柔性直流并网系统的控制与保护技术已成为当下的研究焦点。本文从实际工程出发,针对系统结构、稳态控制、小干扰稳定性、主动频率响应、交直流协调运行及暂态控制等几方面,综述了风电场-柔性直流并网系统的研究成果及发展现状,介绍了当前工程中的技术难点,并对未来的研究方向做了展望。Utilizing voltage source converter based high voltage direct current transmission is the future trend for large-scale long-distance wind farm integration. With the continuous operation of related projects, the control and protection technology for VSC-HVDC systems with wind farms has become the current research focus. Based on actual projects, this paper reviews the research achievements and development status of the VSC-HVDC system with wind farm integration from several aspects, such as system topology, steady state control, small disturbance stability, active frequency response, AC and DC coordinated operation and transient control. The technology difficulties of current projects are introduced, and the future direction of research is prospected.
