摘　　要：海上风电场可及性差,运行条件恶劣。风电机组故障率高,故障修复时间长且维护困难,一旦故障停运,经济损失巨大。统计并对比分析海上风电机组和陆上风电机组的历史运行数据,归纳海上风电机组关键部件的故障特点,分析风力发电机组常见的电气类故障及其对系统的影响。分别从软件容错、硬件容错两个方面总结现有海上风电机组容错运行的研究现状,归纳目前海上风电机组的容错方案,分析现有容错方案的应用可行性。进一步指出现阶段海上风电机组故障容错存在的主要问题,并对将来的研究热点进行了展望。Offshore wind farms have poor accessibility and bad operation conditions. Offshore wind turbines have high failure rate, long repair time and it is difficult to maintain. It will cause huge economic loss once wind turbines fail to shutdown. The history operating data of offshore and onshore wind turbines are counted and deeply analyzed, fault characteristics of key components in the offshore wind turbine are generalized. The electric faults in wind turbines and its influence on the system are analyzed. The research status of existing fault-tolerant operation in offshore wind turbines are summarized from two aspects of hardware and software fault tolerance respectively, fault-tolerant schemes of offshore wind turbines are concluded, and the application feasibility of existing fault-tolerant schemes is analyzed. The main problems of offshore wind power fault tolerance at the present stage are pointed out and the research focus in the future is prospected.
