The Research of Voltage Dip Generator in LVRT Test

摘要：

　　In order to test low voltage ride through of wind power generator system,we need a special voltage dip generator device.This paper summarizes the research status of voltage dip generator and introduces three different technical.The transformer form of voltage dip generator has a simple structure,high reliability and low cost.This voltage dip generator can generate three-phase symmetrical dip,two-phase and single-phase dip.Each of dip has 5 kinds of optional drop depth.It has more suitable for preliminary verification of LVRT test and provides a platform for LVRT formal test.Wind farm test results show that the developed voltage dip generator satisfies the requirement of LVRT.
