Limitations Of A Static VAr Compensator (SVC) With Switched Capacitor Operating As An Active Filter

Abstract

The goal of this paper is to analyze the limitations of a static VAr compensator (SVC) with switched capacitor, when this operate as an active filter.
The limitations considered and studied by simulation are in the zone of ability/inability of the active filter to produce current waveforms and waveforms with the desired di/dt of the desired line current, and from the zone of the operating constraints. The active filter limitations at the desired harmonic frequency hf were quantified with the help of two measures: percentage magnitude error and phase error, in the both capacitive and inductive operation modes.
