摘要:   随着海上风电单机容量和规模的不断增大,常规的35 kV交流集电方案的局限性表现得十分明显,可互联的风机数量越来越少,海缆长度越来越长,单位成本不断增加。提出了高电压等级的66 kV交流集电方案,相比于35 kV交流集电方案在技术和经济上更有优势,不仅能输送大容量电能,而且可节约投资、降低运行费用。对66 kV交流集电方案的设备进行了调研并结合海上风电的发展趋势讨论了66 kV交流集电方案的发展前景。

Abstract:   With the continuous increase in the capacity and scale of offshore wind power units,the limitations of

conventional 35kVAC power collection schemes emerge,which are fewer interconnection wind turbines,longer submarine
cables and increasing costs per unit. A 66 kV AC power collection scheme with a high voltage level is proposed. Compared
with the 35 kV AC power collection scheme,it has more technical and economic advantages. It can not only transmit large
capacity power,but can also save investment and operating costs. The equipment for 66 kV AC power collection scheme is
investigated and its prospect is discussed in combination with the development trend of offshore wind power.
