A Comparison of Power Quality Controllers

Petr Černek, Michal Brejcha, Jan Hájek, Jan Pígl

Abstract


This paper focuses on certain types of FACTS (Flexibile AC Transmission System) controllers, which can be used for improving the power quality at the point of connection with the power network. It focuses on types of controllers that are suitable for use in large buildings, rather than in transmission networks. The goal is to compare the features of the controllers in specific tasks, and to clarify which solution is best for a specific purpose. It is in some cases better and cheaper to use a combination of controllers than a single controller. The paper also presents the features of a shunt active harmonic compensator, which is a very modern power quality controller that can be used in many cases, or in combination with other controllers. The comparison was made using a matrix diagram that, resulted from mind mapsand other analysis tools. The paper should help engineers to choose the best solution for improving the power quality in a specific power network at distribution level.
