Mitigation of Voltage Sag And Swell In DFIG Interconnected With Grid

Abstract

This paper proposes improved ride through of Doubly Fed Induction Generator integrated to a grid under voltage sag and swells. Voltage sag and swell are the most important power quality problems that influences the performance of the DFIG interconnected to the grid. The behavior of DFIG interconnected with grid is investigated for voltage sag and swell. A converter is proposed which improves the ride-through of DFIG interconnected with grid. Simulation is carried out using MATLAB SIMULINK to emphasize the use of proposed converter in enhancing the overall system performance and maintaining the system stability.
