不对称故障下直驱型风力发电系统低电压穿越技术综述

Review of low voltage ride through technology for direct- driven wind power generation system under the unsymmetrical fault

介绍了直驱型风力发电机,重点分析了电网不平衡故障下,直驱式风电机组的直流母线和网侧变流器低电压不间断运行的控制策略。

Direct -driven wind power generation system was introduced. The control measures to keep the low voltage of DC bus and converter which on network side uninterrupted operation under the unsymmetrical fault were analyzed.
