风力发电机组关键技术专利态势分析

The Patent Analysis of the Key Technologies of Wind Turbine

风力发电毫无疑问是最具可持续性的发电技术之一。本文利用德温特创新索引数据库(DII)、德温特数据分析器(DDA)、德温特专利索引(DI)等对全球风力发电领域最主要的叶片技术、主轴承技术、偏航和变桨技术的相关专利进行了分析,从专利申请的时序分布、领域技术主题、重点国家/地区及其重点申请人、专利布局方面等,以期为我国在这一重要能源技术领域中的研发和产业化提供知识产权情报支撑。

Wind turbine technology is one of the most sustainable energy technologies. In this paper, we analyze the time series distribution of global patent applications, technology themes, the situation of patent applications in the key countries or regions, and the significant patent assignees of wind turbine technologies on blade, bearing, yawing and variable pitch by using Derwent Innovations Index （DII）, Derwent Data Analyzer （DDA） and Derwent Innovation（DI）. It is hoped that through the analysis of this paper, some intellectual property intelligence advises can be provided for the future development and industrialization in the field of wind turbine technology of China.
