A practical fast acting control scheme for fuzzy logic-based voltage stabilization control

Abstract EN

This paper presents a simplified control model for stabilizing a load voltage using a switched reactor in parallel with a fixed capacitor of static VAR compensator.

Two IGBT’s are used to control the reactance of the switched reactor.

A uniform pulse width modulation is used for controlling the two switches.

The compensator has a simple control circuit and structure.

A complete modeling and numerical simulation for the proposed systems is presented.

A high speed Digital Signal Processor is used for implementing proportional-integral (PI) and fuzzy load voltage controllers.

Experimental results indicate the superiority of fuzzy logic control over the conventional proportional-integral control method.

Simulation results are reported and proved to be in good agreement with the relevant experimental results.
