| 摘 要： | 目前，国内外对DFIG的研究主要侧重于风力发电机组控制策略方面，而对于不同电网故障情况下DFIG的运行特性分析较少。鉴于此，在DIgSILENT／PowerFactory下建立TDFIG模型，利用含风电场的WSCC三机九节点仿真系统，进行了电网不同故障情况下的一系列仿真，重点分析了电网不同故障情况下DFIG的运行特性，研究了风电场与电网之间的交互影响及相应的保护措施，为大规模风电接入电网的运行控制提供依据。

| Abstract: | At present, researches on DFIG are mostly focused on the control strategy of wind power generators while the operation characteristics of DFIG with different faults occurred in power grid are little analyzed. In view of this condition, DFIG model is established in DIgSILENT/PowerFactory in the paper. And a series of power grid fault simulations are conducted under different fault conditions of the power grid by means of WSCC 3-generator and 9-node simulation system consistent of wind farms with focus on the studies on the operation characteristics of DFIG and interactions between the wind farm and power grid and the corresponding protection measures. The study as described in the paper can provide references for the operation and control of power grid with large-scale wind power integration. |
