摘要
为了测试和研究风电系统的低电压穿越能力,需要利用一种电压跌落发生器模拟电网规范中的各种电网故障。本文给出了一种新型的低成本电压跌落发生器,利用可控器件IGBT在调压器的原、副边之间切换来实现电压跌落,并控制电压跌落的类型、深度、持续时间和起止相位。
In order to test the LVRT capability of the wind power generation system, a voltage sag generator（VSG） is required to simulate different kinds of grid faults. This paper introduces a new in the transformer primary side and the vice-side switch between in and start-stop phase of voltage dip can be controlled. lower cost of voltage dip generator, which using IGBT devices order to achieve voltage drop. Further more the type, depth
