Overview of Offshore Wind Power Transmission and Power Transportation Technology

Abstract

In recent years, the new power system with new energy as the main body is developing rapidly, and the offshore wind power plant is developing towards the trend of deep sea and large capacity. In view of the limitations of the current transmission mode, changing the traditional cable transmission mode provides new possibilities for the research of power transmission from the perspective of transport batteries. First of all, based on the actual operation of the existing offshore wind power projects, the working principle and status quo of the main offshore wind power transmission modes, such as alternating current power transmission mode and direct current power transmission mode, were analyzed, and the working mode of the transport battery was described. Then, the technical and economic performance indexes such as transmission capacity, investment cost and security cost of transport battery and other transmission schemes were compared. Finally, the advantages and disadvantages of offshore wind power transmission modes were analyzed.
