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.
