【摘要】：随着海上风电场的快速建设,经济有效的大规模海上风能汇聚和传输方式已被日益关注。为了使未来的海上风电场更好地采用高压直流输电并网,先进的直流变换和直流风机的概念被引入,以形成全直流型风电场。针对海上全直流型风电场4大关键科技问题的国内外研究现状进行梳理,包括:组网方式(有无升压站)与评价方法;关键设备(直流风电机组、海上升压站中直流变压器、岸上换流站和直流断路器)技术;运行与控制;故障与保护。结合以上关键技术的发展趋势,对未来海上全直流型风电场进行展望,并给出一种基于模块化多电平技术的推荐配置。
[Abstract]:With the rapid construction of offshore wind farm, more and more attention has been paid to large-scale offshore wind power gathering and transmission. In order to make the future offshore wind farm better adopt HVDC transmission and grid connection, the advanced concepts of DC transformation and DC fan are introduced to form a full-DC wind farm. This paper reviews the domestic and international research status of four key scientific and technological problems of offshore full-DC wind farm, including: networking mode (whether there is a boost station) and evaluation method, key equipment (DC wind turbine, DC transformer in offshore booster station, etc. Technology for onshore converter stations and DC circuit breakers; operation and control; failure and protection. Combined with the development trend of the above key technologies, the future of all direct current wind farms at sea is prospected, and a recommended configuration based on modularized multilevel technology is given.
