VSC for reactive power control of transmission line with fast response

Abstract

The STATCOM is shunt connected devices of Flexible AC Transmission Systems (FACTS) family using the principles of power electronics. A new multilevel voltage-source inverter with separate dc sources is proposed for high-voltage, high-power applications. This paper discuss about implementation of VSC by using cascade H-bridge for reactive power compensation of transmission line. Conventional control and Fuzzy control schemes are implemented in order to achieve the complete close-loop operations achieve effective reactive power control. These control schemes are simulated for the real-time control along with real-time modeling and simulations. Relative Harmonic analysis is discussed. The results are prominent and give a way for real-time implementation
