摘　　要：1 Background The offshore wind resources of China are widely distributed and have large regional differences.The Yellow Sea and Bohai Sea areas,which account for 60%of the developable sea area,have an annual average wind speed of less than 7.5 m/s(Xu et al.,2013).According to the current level of offshore wind power transportation,construction,and operation and maintenance,the profit balance point of 5.0 MW offshore wind turbines is 3000 h/year(Zheng,2017).However,in the Yellow Sea and Bohai Sea areas,even if the world’s best offshore wind turbines at that time are used,their full power generation hours can only reach approximately 2900 h/year.This phenomenon is on the verge of profitability or loss,resulting in a large number of sea areas,especially the Bohai Sea area,with no development value.Therefore,developing offshore wind turbines with strong power generation capacity and low cost,which is suitable for the sea areas in China,is urgently needed.Thus,the H1715.0 MW offshore wind turbine project is introduced.
