Application of SVG in High-voltage Power systems

The static var generator (SVG) is one of the new generation flexible AC transmission systems (FACTS) devices with a promising future of applications due to advancements in power electronics and microelectronics technologies. It is an ideal device to stabilize the voltage and enhance the power factor for high-voltage systems. This paper discusses some application-related problems of SVG. After the operational principles and voltage and current control methods of SVG are presented, its dynamic process is analyzed. The multi-series technique and zigzag link mode of transformer is utilized in order to eliminate output harmonic of SVG without additional facilities. Finally, the results of simulative experiment are given to verify the feasibility of the proposed control methods.
