This paper investigates the worldwide development status of wind power and the main opinions and advantages of offshore wind power development in the industry, and summarizes that the development of offshore wind power will be in the direction of large capacity and distant sea area. At the same time, the distribution of wind energy resources in China’s coastal areas is investigated, and combined with the constraints of offshore wind energy development in China, it is concluded that offshore wind power development in China will also develop to distant sea areas. Secondly, three transmission modes including power frequency AC, flexible HVDC and low frequency AC are briefly described, and the technical economy of the three modes is analyzed with typical cases. In addition, the technical feasibility of 400 MW offshore wind power Grid-connected through low-frequency transmission technology is verified by system model building and simulation. Thirdly, combined with the development trend of offshore wind power, current research and manufacturing level, the opportunities and challenges of the application of low frequency transmission technology are analyzed. Finally, the main points of this paper are summarized. It is preliminarily clear that the low-frequency transmission mode has better technical and economic performance within a certain transmission distance, and can be used as a beneficial supplement to the conventional power frequency and flexible HVDC transmission mode.
