A fast two-vector Phase-locked loops (PLL) control has been proposed to the phase and frequency of grid voltage using 48-pulse switching. The novel controller senses shift as a deviation by load locked positive sequence. was designed track angle kept within satisfying rang at all time. PI- obtain desired performance PLL. PLL voltage. test results shows that new design can response sequence betw...

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 ...

In this paper, the compensation of voltage sags and swells using a dynamic restorer (DVR) based on bi-directional AC/AC converter is presented for stabilizing single-phase AC line voltage. The H-bridge with switches without bulk capacitor adopted as power topology proposed system. novel DVR to compensate both sag swell conditions. Additionally, factor closed unity because not required. inner ou...

Power quality is one of major concerns in the present area. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply that results in a failure of end use equipment’s. One of the major problems dealt here is the voltage sag. To solve this problem, custom power devices are used. One of those devices is ...

The dynamic voltage restorer (DVR) combined with a photovoltaic–thermoelectric generator (PV-TEG) system is proposed for disturbance compensation in the three-phase four-wire distribution system. PV-TEG hybrid energy source used DVR to improve ability deep and long-period power quality compensation. In addition, will save grid consumption when module generates sufficient meet load demand. An en...
