In this paper, an Advanced Static VAR Compensator (ASVC) based on a voltage type inverter is presented and analysed. The ASVC, which uses the Pulse Width Modulation (PWM) technique, will be modelled in the Park system. Moreover, a low pass filter is introduced at the output of the inverter in order to eliminate the high order harmonics. The proposed system may compensate inductive or capacitive reactive power. The mathematical model thus obtained will be used for the design of a linear quadratic Gaussian (LQG) multivariable (MIMO: Multiple Input Multiple Output) control strategy. The simulation results obtained with MATLAB software are included and will be thoroughly discussed in this paper.
