Overview of Existing Solutions for Fault Ride through Capability Improvement of DFIG used in Wind Turbines

Abstract

The growing of wind generation gives arise for new challenges for its integration to the network tripping of large amount of wind power will lead to serious consequence to the grid. in this paper DFIG performance used in wind turbine during voltage dip due to fault. Wind turbines equipped with doubly-fed induction generators (DFIG) can regulate easily the reactive power generated in steady state. However, challenges appear when reactive power has to be generated during voltage dips. A survey of the problems associated with voltage dips and solutions for Ride Through operation of this type of system are given. an overview of different alternatives for Low Voltage Ride Through are presented in this paper.
