海上风电机组国产化研究与实践

Research and Practice on Localization of Offshore Wind Turbines

统计并分析了海上风电机组叶片、主轴、电气系统、控制系统等关键部件和系统的技术现状及国产化状态,针对目前海上风电机组部件与系统中存在的国产化弱项,采用理论分析、材料/部件选型、部件研制、测试验证、整体组装的思路,进行叶片、主轴承、变流器、可编程逻辑控制器(programmable logic controller,PLC)等部件和系统的国产化研制,并采用研制的国产化部件和系统进行5 MW国产化海上风电机组装配,该机组的国产化率达到95%以上。结果表明:海上风电机组的大部分部件与系统具备国产化条件,部分设计(如叶片设计等)所用工业软件仍依赖进口,少部分核心元器件国内仍然缺失。

This paper analyzed the localization status of key components and systems in offshore wind turbines such as blades,spindles,electrical systems,and control systems.In view of the localization weaknesses existing in the components and systems of offshore wind turbines,the localization of blades,main bearings,converters and programmable logic controller(PLC)was carried out by using the ideas of theoretical analysis,material/component selection,component development,test verification and overall assembly,and 5 MW offshore wind turbines were assembled with the developed localization components and systems.The localization rate of the unit was more than 95%.The results show that most of the components and systems of offshore wind turbines have the conditions for localization,but some technologies,such as blade design,still rely on imports,and a few core components are still missing in China.
