大容量海上风电机组发展现状及关键技术

Development Status and Key Technologies of Large-capacity Offshore Wind Turbines

随着陆上和近海风电资源紧缺,海上风电场选址从近海走向深远海,规模已达吉瓦级,海上风电机组也向10 MW级以上发展。针对大容量海上风电机组,首先阐述了国内外海上风电机组容量、类型及变流器等关键技术的发展现状。其次,对大容量三相和多相化海上风电机组及其遇到的问题和关键技术进行分析,给出了未来多相化海上风电机组的拓扑结构设计和控制策略优化方法。最后,对大容量海上风电机组发展趋势进行了总结。

With the short supply of onshore and nearshore wind power resources,the site selection of offshore wind farms is from nearshore to the deep distant offshore,the scale reaches gigawatt level,and the capacity of offshore wind turbines is developing to more than 10 MW level.For large-capacity offshore wind turbines,this paper firstly describes the development status of key technologies such as capacity,types and converters of offshore wind turbines in China and abroad.Secondly,this paper analyzes the problems and key technologies of the large-capacity three-phase and multi-phase offshore wind turbines,and gives the development trend of topology design and control strategy optimization method of the future multi-phase offshore wind turbines.Finally,this paper summarizes the large-capacity offshore wind turbines.
