AN ADVANCED STATIC VAR COMPENSATOR BASED ON A THREE LEVEL IGBT INVERTER MODELLING ANALYSIS AND ACTIVE POWER FILTERING

Azeddine Draou

   This paper presents the dynamic performance analysis of an Advanced Static Var Compensator (ASVC) using three-level neutral point-clamped voltage source inverter. The paper presents the principles of operating and the method of reference currents generation. The dynamic behaviour of the system is further analysed using Matlab/Simulink with SimPower Systems toolbox through a set of simulation tests. The results obtained have been applied to an active power filter which might lead to the design of a robust controller for current harmonics and reactive power applications.
