摘要:
基于德温特数据库中的专利信息,通过对比海上风电和其他海洋主要可再生能源的年专利信息,结合海上风电专利数量与碳减排压力以及年新增装机数量之间的相关性分析,对海上风电技术发展做了分析,归纳了海上风电的重点技术领域;构建了海上风电技术成熟度预测分析模型。分析结果表明,海上风电技术发展迅速,目前整体的技术成熟度已达到0.87,已从成熟期进入饱和期。浮式风电作为一种具有替代性特征的新兴技术,也得到了快速的发展,目前的技术成熟度已达到0.54,从技术成长期进入技术成熟期。

Abstract:
Based on the patent information collected from the Derwent Innovation Database, this paper analyzes the annual patent information of offshore wind and other major ocean renewable energies. The correlation between the number of patents for offshore wind, the pressure of carbon emission reduction, and the number of new installed capacity per year are also evaluated. The development of offshore wind power technology is explored and the key technological fields of offshore wind power are summarized. This study proposes a prediction and analysis model of offshore wind technology based on the patent information analysis. The results reveal a rapid development of the offshore wind power technology reaching a technology maturity of 0.87. This signifies that it has entered the saturation stage from the mature stage. As a new alternative technology, floating offshore wind has also been developed rapidly with maturity reaching up to 0.54. This implies that it has just entered the mature stage from the technology expansion stage. This research shows that the patent analysis technology and technology maturity prediction can be effectively used to analyze the key technology fields of offshore wind power and predict its technology maturity.
Key words:  offshore wind  technology maturity  patent analysis
