摘要: 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 connected electrical grid, DVR which constitution of three H-bridge inverters supplied through common DC capacitor, can recover 50%, alternatively it operates as an uninterruptable power supply failure occurs in grid supply. The Fuzzy Logic Controller (FLC) be used instead proportional controllers PI because its efficiency nonlinear systems; there are two side converter replaced by FLC, simulations were carried out simulink/Matlab software, results show reliability FLC terms synchronization time.
