摘要
分析了双馈异步发电机(DFIG)在电网电压跌落时的暂态过程,通过人工接地短路试验测试了风电场升压站内110 kV母线电压和风机出口处电压、电流的故障波形。针对风电场在故障时存在的问题,对静止无功发生器(SVG)在提高DFIG低电压穿越能力中的作用进行了仿真,并通过现场试验对仿真的结论进行了验证。
The transient process of doubly-fed induction asynchronous generator under fault conditions is analyzed, the fault curves are tested for 110 kV bus voltage and current of a booster station and the outlet voltage and current of a wind turbine by artificial short-circuit test. The effects of static var generator （SVG） on improving the low voltage ride through ability are verified by simulation when fault exits in wind farm. Field experiment proves the results of simulation.
