A current regulated switched capacitor static volt ampere reactive compensator

This paper introduces a current regulated switched capacitor static VAr compensator (SVC). The physical mechanisms governing the performance of the switched capacitor SVC are explained in detail. A relevant equivalent circuit is presented which helps prove that the oscillation of reactive power takes place in two different loops; between the main 60 Hz source and the AC input of the converter bridge; and between the energy storing device (in this case, a capacitor) and a set of fictitious voltage sources used for modeling the solid-state switches. The paper discusses the performance of such a device and presents the basic analytical expressions.<
