Simulation and Experimental Analysis on the Grid Connected Doubly Fed Induction Generator Wind Turbines

随着风电并网规模的不断扩大,风电功率波动对所接入电力系统调峰、调频等运行性能的影响将越加显著。为获得双馈感应风电机组联网运行特性并校验所建模型的有效性,进行了接于实际电力大系统的风电场短路试验。通过对实测数据的分析辨识出风电机组的动态特性;基于所建模型对短路试验进行了仿真重现。实测结果与仿真结果相吻合,验证了所建模型的有效性。

Large scaled wind power integration into power system increasingly imposes significant impacts on the system operations such as the peak load regulation and frequency regulation, To obtain the operational characteristics of doubly fed induction generators （DFIGs） and validate models, the short circuit testing on a grid connected wind farm was carried out, and the dynamic performance of DFIG was identified by the recorded field test data, Based on the established model, the short circuit tests were simulated and consistent results were obtained.
