Research on the development trend of offshore wind power technology based on patents

Abstract

To achieve the goal of “double carbon”, offshore wind power is one of the important directions of energy transformation. In order to comprehensively grasp the overall development trend, key fields and hot technology development direction of offshore wind power technology, the relevant literature and global offshore wind power patent datum are analyzed, the offshore wind power technology system is constructed, and six key technology fields are determined. The analysis shows that the current global offshore wind power technology is in a period of rapid development; China started late, developed rapidly, and has an absolute advantage in the total number of patent applications; China has certain technological advantages in terms of HVDC transmission network and pile foundation, but the global layout is insufficient and the number of high-value patents is small, so it is urgent to innovate in key core technologies. In the future, the innovation of offshore wind turbine technology, grid connected transmission technology, management, operation and maintenance technology and offshore wind power integration application technology will continue to grow. Among them, large-scale installed capacity, flexible DC transmission, floating support, intelligent operation and maintenance, hydrogen production technology are the key directions for enterprises to carry out R&D and technical layout.
