Overview of voltage sag mitigation

2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002
This paper gives an overview of methods used in the mitigation of voltage sags. Different solutions for improving the performance of the power system, as well as the immunity of the equipment, are described. Finally, mitigation devices to be installed at the system-load interface for power quality enhancement are presented.

Voltage sag compensation with energy optimized dynamic voltage restorer

IEEE Transactions on Power Delivery, 2002
The compensation capability of a dynamic voltage restorer (DVR) depends primarily on the maximum voltage injection ability and the amount of stored energy available within the restorer. A new phase advance compensation (PAC) strategy for the DVR is proposed in order to enhance the voltage restoration property of the device.

Voltage Sags in Industrial Systems.

RE&PQJ
This paper presents results relating to the effect of voltage  sags  in  industrial  systems  on  adjustable  speed   drives.   The   influence   of   the   source   impedance,  dc  link  capacitor,  characteristics  of  voltage   sags   and   the   effect   of   the   utility   is   computed.

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.
