Abstract

A high performance advanced static VAR compensator (ASVC) which uses a voltage source inventer is presented and analyzed in this paper. The ASVC system is mode/ed using the d-q transform and employs a programmed PWM voltage wave shaping pattern to simplify the logic software and hardware requirements. The inverter system can compensate leading and lagging reactive power supplied to the load connected to the supply. This model is used 10 design decoupled control strategy, which is based on the control of the modulation index and the phase angle of the switching pattern.Simulated results obtained with MATLAB are also presented and discussed to validate the mode!.
