This paper presents the technical aspects of designing a dynamic voltage restorer to meet the stringent requirements of voltage dips mitigation with respect to the magnitude of voltage dip, fault duration, permissible line voltage deviations and response time. An introduction to the IGCT technology based on latest transparent anode GTO (T-GTO) and gate technology is given. The performance of the DVR based on digital simulations is discussed. A description of a hardware based real time simulator model for performance assessment of DVR in voltage dips mitigation is presented. The results of the real time simulator are compared with the digital simulations. Finally, control and protection concepts for the DVR are highlighted.read more

Voltage sag compensation with energy optimized dynamic voltage restorer
TL;DR: In this paper, a phase advance compensation (PAC) strategy for the DVR is proposed in order to enhance the voltage restoration property of the device, which requires only an optimum amount of energy injection from the DVM to correct a given voltage sag.

Performance improvement of the dynamic voltage restorer with closed-loop load voltage and current-mode control
TL;DR: In this paper, the performance of a dynamic voltage restorer (DVR) in improving the quality of power supply is examined, and it is shown that the existing open-loop control strategy used in the DVR to regulate load voltage can produce poorly damped response due to the presence of the switching harmonic filter in the restorer.
