A Dynamic Voltage Restorer (DVR) based interface scheme for microgrids
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper deals with the issues related to the interconnection between the microgrid and main network. The Dynamic Voltage Restorer (DVR) is proposed as an interface between the main network and microgrid in order to improve reliability and limit fault currents. The performance of DVR is demonstrated during fault conditions in two different locations,

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 ...

Study on Compensation of Voltage Sag and Voltage Swell by Using DVR (Dynamic Voltage Restorer)
2018 International Conference on Current Trends towards Converging Technologies (ICCTCT), 2018Significant feature for electrical engineering is quality of power in modern days. Due to growing use of solid state, non-linear, power semiconductor switching devices power quality issues are formed. A power quality crisis refers to the problems that are cause by the increase of a non standard voltage or current or frequency.
