Abstract :
DVR is an equipment which was connected in series and adjusting the loading voltage by feeding the voltage in
system. The first installation was in 1996. Usually DVR installed between sensitive loads feeder and source in distribution system. The main duty is to fast support load voltage (by fast response energy storage device) during disturbance to avoid any disconnection. In this paper approaches to compensate for voltage sag as a common disturbance in voltage transmission and distribution networks is presented. Super conducting Magnetic Energy Storage (SMES) based DVR is proposed for fast response and effective sag compensation capabilities. The proposed method has the potential to bring real power storage characteristics to protect consumers from the grid voltage fluctuations. To evaluate the performance of the proposed design MATLAB/SIMULINK tool is used.
