Design Considerations of a Fault Current Limiting Dynamic Voltage Restorer (FCL-DVR)
IEEE Transactions on Smart Grid, 2015This paper proposes a new fault current limiting dynamic voltage restorer (FCL-DVR) concept. The new topology uses a crowbar bidirectional thyristor switch across the output terminals of a conventional back-to-back DVR. In the event of a load short, the DVR controller will deactivate the faulty phase of the DVR and activate its crowbar thyristor to ...

Modeling and Simulation of Dynamic Voltage Restorer (DVR) Based on Hysteresis Voltage Control
IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society, 2007Dynamic Voltage Restorers are utilized to protect sensitive loads from voltage sags and swells which take place in the distribution systems. In this paper, a Dynamic Voltage Restorer (DVR) based on hysteresis voltage control is proposed. The DVR is modeled using Simulink'SimPowerSystem Toolbox.

An experimental investigation of dynamic voltage restorer (DVR)
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002An experimental investigation on the performance of a dynamic voltage restorer (DVR) is presented in this paper. It is seen that under certain nonlinear loading conditions, the effectiveness of the DVR is seriously impaired due to the finite voltage drop in the transformer and filter impedances.

Review of voltage compensation methods in dynamic voltage restorer (DVR)
2012 IEEE Power and Energy Society General Meeting, 2012Voltage sag is a common and undesirable power quality phenomenon in the distribution systems which puts sensitive loads under the risk. An effective solution to mitigate this phenomenon is to use dynamic voltage restorers and consequently, protect sensitive loads. Four basics compensation methods were proposed in the research community to eliminate the
