A PSCAD/EMTDC Model for H-Bridge Converter Based DVR for Mitigation of All Symmetrical & Asymmetrical Faults

Abstract

The growth in the use of power electronics has created a greater awareness of power quality. Power Quality (PQ) has been an issue is becoming increasingly pivotal in industrial electricity consumer's point of view in recent times. PQ has become important, especially, with the induction of sophisticated load, whose performance is very sensitive to the quality of power supply, so such type of problems can eliminate by using custom power devices. One of these modern devices is the Dynamic Voltage Restorer (DVR), which is a more efficient and effective modern custom power device. This paper presents the analysis & design of three phase Hbridge converter based DVR for protect sensitive load from polluted distributed network. The main objective of this paper is to save sensitive load from non linear voltages, currents and avoid PQ problem like voltage sag, swell conditions, in addition to the phase angle jump. Modeling & simulation of proposed DVR are implemented in PSCAD/EMTDC platform.
