The Regulation of Grid and Motor Side Converter of DFIG in LVRT

Abstract:

The most widely used generator type is the Doubly-Fed Induction Generator (DFIG). Because of the close coupling of the generator and the gird, the stator flux of DFIG is distorted while the Grid voltage dip happens. To achieve the LVRT, the LVRT control strategy of DFIG, especially the association of gird side and rotor side converter, is discussed under gird voltage dips. Simulation and experiment have been implemented to prove the idea.
