Design and implementation of laboratory scale static var compensator to demonstrate dynamic load balancing and power factor correction

Abstract

This paper presents the design and implementation of a lab scale FACTS device SVC (Static Var Compensation) for dynamical load balancing. The algorithm presented here is based on the Steinmetz method to balance a single phase load at the end of a 3-phase transmission line. The developed board connects to LabVolt bench equipment to complete the SVC system. The digital implementation of this compensator is done using a Texas Instruments microcontroller. The SVC is intended for demonstrating SVC operation and dynamic load balancing fundamentals to students.
