Hardware Implementation of Dynamic Voltage Restorer to Reduce Voltage Sag/swell [PDF]
International Journal For Multidisciplinary ResearchVoltage sag disturbances are the most common Power Quality issues in distribution systems. Dynamic Voltage Restorer is usually used as a way to reduce voltage sag. The suggested method requires fewer switching devices and has superior compensating capabilities compared to frequently utilised compensators.
