大容量海上风电场500kV海底电缆选型分析

Analysis of 500 kV Submarine Cable Selection for Large Capacity Offshore Wind Farm

近年来,国家大力发展风电等新能源项目,海上风电场主要通过海底电缆将电能送出,而随着风电场容量逐步增大,离岸距离加大,为了满足风电场的容量需求,需考虑采用超高电压等级的海底电缆,而这方面国内应用经验不多,实施难度较大。该文对海底电缆的性能、选型等方面做了一定的研究,针对1000 MW容量的风电场,从设计角度考虑,分析了500 kV海缆的选型与应用。

In recent years,China has vigorously developed wind power and other new energy projects.Offshore wind farms mainly transmit electric energy through submarine cables.With the gradual increase of wind farm ca‐pacity and offshore distance,in order to meet the capacity demand of wind farms,ultra-high voltage submarine cables need to be considered.In this regard,there is little domestic application experience and it is difficult to implement.In this paper,the performance,selection and other aspects of submarine cable are studied,and the selec‐tion and application of 500 kV submarine cable is analyzed from the design point of view of 1000 MW wind power plant.
