基于专利的海上风电技术发展趋势研究

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

摘要

要实现“双碳”目标，海上风电是能源转型的重要方向之一。为了全面掌握海上风电技术总体发展趋势、重点领域及热点技术发展方向，深入系统分析相关文献及全球海上风电专利数据，构建海上风电技术体系，确定了六个重点技术领域。分析表明，当前全球海上风电技术整体处于快速发展期；我国起步晚，发展高速，专利申请总量上占有绝对优势；在高压直流输电网络、桩基础等方面我国具有一定技术优势，但全球布局欠缺，拥有高价值专利数量少，亟需在重点核心技术方面进行创新；未来海上风电机组技术、并网输电技术、管理运维技术及海上风电融合应用技术的创新仍然会保持增长态势，其中：装机容量大型化、柔性直流输电、漂浮式支撑、智慧运维、制氢技术等是企业开展研发，进行技术布局的重点方向。

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.
