Reactive power compensation by TBSC compensator with eliminate harmonic resonance

The capacitor is used for reactive power compensation but there is harmonic resonance which becomes a very serious problem for reactive power compensation in power systems, this paper presents reactive power compensation without creating harmonic resonance under variable load condition. As a result, the planned controller can be function as a retrofitting device to replace existing reactive power controllers with little variations. Topology for reactive power compensation suitable for dynamic loads in closed loop system. The scheme consists of(TBSC) Thyristor Binary Switched Capacitor banks are used for reactive power compensation and avoiding harmonic resonance problem.
