Received Jul 15, 2016 Revised Mar 13, 2017 Accepted Mar 27, 2017 Interline Dynamic Voltage Restorer (IDVR) comprises of several Dynamic Voltage Restorers (DVRs) connected to different distribution feeders in the power system sharing common energy storage. One of the DVR provides for voltage sag compensation appearing in that feeder, while the other DVRs restore the energy in the common dc-link ...

Aiming at the micro-grid deteriorating the distributed network power quality for its features like voltage fluctuation and intermittent, unified power quality conditioner (UPQC) is the most effective device for power quality treatment. The voltage sag detection of UPQC based on PI with RBF (Radial Basis Function) neural network controller is put forward in the paper. The UPQC topology which inc...

The “Power Quality” term is widely used in recent years in power system field. Voltage sags is one of the power quality issue, which is also known as dips, are important to industrial reliability. This paper presents a power world simulation approach to find the voltage sag magnitudes in power system network. In this paper, investigations have been conducted on a sample distribution system mode...

Power quality is one of major concerns in the present era. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or mis-operation of end user equipments. One of the major prob...
