本文介绍了一个实验室规模的双馈风力发电机测试设备委托调查的低电压故障行为的双馈风力涡轮机发电机。在该DFIG测试设备中，由四象限直流驱动器驱动的直流电动机被用作原动机，以复制来自风力涡轮机驱动轴的扭矩输入。在Simulink中创建的机械模型由dSpace控制器执行。IGBT功率转换器和直流链路电容器被过额定以承受各种电网故障。故障仿真器允许电网故障的应用的灵活方法，并且还提供了模仿风力涡轮机的典型电网连接阻抗的机会。
This paper has described a laboratory-scale DFIG test facility commissioned to investigate the low voltage fault behavior of a DFIG wind turbine generator. In this DFIG test facility, a dc motor driven by a four-quadrant dc drive is used as a prime mover to replicate the torque input from a wind turbine's drive shaft. A mechanical model created in Simulink is executed by the dSpace controller. The IGBT power converter and dc-link capacitors are over-rated to withstand various grid faults. The fault emulator permits a flexible approach to the application of grid faults and also provides an opportunity to mimic the typical grid connection impedance of a wind turbine.
