Low-voltage ride through capability for DFIG wind turbine system based on series grid side converter
This paper proposes a low-voltage ridethrough (LVRT) capability for a doubly-fed induction generator (DFIG) wind turbine (WT) system. With the proposed method, series grid-side converter (SGSC) in which its DC-side connected at the DC bus of the back-toback converters and its AC-side connected in series with line through transformer have been applied, enables to compensate a voltage response of the system during the grid faults and to reduce the capital cost.
