UPQC THESIS

One modern and very promising solution that deals with both load current and supply voltage imperfections is the Unified Power Quality Conditioner UPQC. Conventional power quality mitigation equipment is proving to be inadequate for an increasing number of applications, and this fact has attracted the attention of power engineers to develop dynamic and adjustable solutions to power quality problems. Also, the software-based UPQC protection approach is investigated, the implementation of which does not require additional hardware. The main protection element is a crowbar connected across the secondary of the series transformer and consisting of a pair of antiparallel connected thyristors, which is governed by a very simple Zener diode based control circuit.

Skip to main content. In order to protect the series inverter of the UPQC from overvoltage and overcurrent during short circuits on the load side of the UPQC, the secondary of the series transformer has to be short-circuited in a reasonably short time microseconds. Nowadays, much of the equipment is based on power electronic devices, often leading to problems of power quality. Title Unified Power Quality Conditioner: Abstract The proliferation of power electronics-based equipment has produced a significant impact on the quality of electric power supply. This thesis investigates the development of UPQC protection scheme and control algorithms for enhanced performance.
