Mitigation of voltage sags for balance and unbalanced voltage in low voltage distribution system

Abstract EN

This paper proposes a mitigation of different types of voltage sags in low voltage distribution system using an effective series compensator or Dynamic Voltage Restorer (DVR) with new configuration of its topology.

The main function of the DVR is to maintain the voltage at the sensitive load from balance and unbalance voltage sags.

The developed system can compensate voltage sags in the grid and at the end can be used for the protection of sensitive loads in the network.

DVR under various load conditions and different types of fault in both single phase and three phases were investigated.

A prototype of the proposed scheme was built and tested in order to test its feasibility through extensive experimental studies.
