Abstract
The paper presents a mathematical model derivation of an Advanced Static Var Compensator (ASVC) using three-level inverter.
The system is analysed using MATLAB through a set of simulation tests, to determine the effect of the DC-side capacitors on the harmonic performance, and dynamic behaviour.
The control of the system is carried out using the d-q axis transformation and the implementation of a PI regulator. The results obtained are given, discussed and may lead to correct design of a robust controller for reactive power applications.
