Abstract

In this paper a Doubly Fed Induction Generator (DFIG) based Dynamic Voltage Restorer (DVR) is proposed to handle voltage sag and swell when the DFIG is connected to the electrical grid, the DVR which is a constitution of three H-bridge inverters supplied through a common DC capacitor, can recover sag to 50%, alternatively it operates as an uninterruptable power supply when a failure occurs in the grid supply. The Fuzzy Logic Controller (FLC) is proposed to be used instead of proportional controllers PI of the DVR because of its efficiency in nonlinear systems; there are two controllers in the grid side converter of the DVR which are replaced by two FLC, the simulations were carried out in simulink/Matlab software, the results show the reliability of the proposed DVR based FLC in terms of voltage sag and synchronization time.
