Abstract

Abstract: 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.

Key words: offshore wind power, direct current(DC) transmission, alternating current(AC) transmission, aggregation boost, economy, energy loss
