Transformerless Dynamic Voltage Restorer for voltage sag mitigation

2016 Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy (PESTSE), 2016
Dynamic Voltage Restorers are identified to be cost effective solution for protecting sensitive loads from voltage related power quality issues. The extension of cost reduction and efficiency can be improved by eliminating the injection transformer. This paper discusses a transformer-less dynamic voltage restorer based on three-single phase Voltage ...

Method to Select Optimal Device for Mitigating Voltage Sag Based on Voltage Sag Assessment

The Transactions of The Korean Institute of Electrical Engineers, 2015
This paper presents a method to select optimal device for mitigating voltage sags. The method is based on economic evaluation and voltage sag assessment involving sag duration as well as magnitude. The economic evaluation is performed by using the operation cost and economic benefit of the mitigation devices.

Before and during voltage sags

IEEE Industry Applications Magazine, 2005
The relationship between the voltages and the tripping level for line-operated synchronous machines is discussed. Voltage sags may cause tripping and large torque peaks in electrical machines. Tripping is caused by undervoltage protection or overcurrent protection.
