| 摘 要： | 海上风电机组面临故障率高、停运损失大等问题,迫切需要及早发现运行故障、及时提供容错机制。构建基于西蒙决策理论的双馈风力发电机开路故障容错设计方案,选取电能质量和风力发电机组可靠性作为典型评估指标。结合双馈风力发电机组机侧变流器单相开路故障容错案例,给出量化的容错性能指标。结果表明及时有效的故障容错机制能够提高海上风电场的可用率,避免故障恶化,降低故障带来的经济损失。

| Abstract: | Faced with high failure rate and large outage losses, offshore wind farms needed to find operation faults and provided faulttolerant mechanism as soon as possible doublyfed wind generators (DFIGs) opencircuit faulttolerant projects were built based on simon decision theory, which took power quality and wind turbine reliability as typical evaluation standards. The tolerant effect was evaluated combining the example that was doublyfed wind generators rotor side converter single phase open circuit fault. The results showed that timely and effective faulttolerant mechanism could raise availability, avoid fault deterioration and reduce economic losses caused by faults in offshore wind farms. |
