摘　　要：海上风电场逐渐向深海远海领域发展,其中风力发电机单机容量不断增大,海上风电场运行环境多变、建设难度增加等问题也随之而来。针对这些问题,对海上风电在高压直流输送条件下的多种电能汇集升压方式进行理论分析;之后从经济性和能量损耗角度出发,将几种汇集升压方式应用于切合实际的具体工程案例,分别计算各方案的建设成本及在汇集电能过程中的能量损耗,对计算结果进行汇总;对比分析汇集升压过程中不同电压等级及电能类型对海上风电汇集系统的影响,并证明直流汇集升压系统在海上风电未来发展中所展现的优势。With the gradual development of offshore wind farms to the deep and distant ocean and the increasing single machine capacity of wind turbine generator in offshore wind farms,problems such as changeable operating environment and increasing construction difficulty of offshore wind farms also arise.Aiming at these problems,a variety of aggregation boost methods of offshore wind power under the condition of HVDC transmission are theoretically analyzed.From the perspective of the economy and energy loss,the construction cost of each program and energy loss in the process are calculated respectively by applying several aggregation boost methods to practical concrete engineering cases.The calculation results are summarized,and the influence of different voltage levels and power types on the offshore wind power collection system is compared and analyzed,and the advantages of DC aggregation boost system in the future development of offshore wind power are proved.
