CONTROL DESIGN OF STATCOM USING FIVE LEVEL NEUTRAL POINT CLAMPED CONVERTER AND ITS APPLICATION TO REACTIVE POWER

This paper deals with multilevel neutral point clamped (NPC) converter voltage source inverter applied as STATCOM. The proposed control with space vector modulation (SVM) switching and decoupled current control with IF controllers have been tested to prove the advantages of the proposed control. The effectiveness and validity of the controller system is supported by computer simulation. Simulation results obtained confirm that the controller has a very good performance, allowing compensation of capacitive or inductive. The simulation of the proposed system is developed using MATLAB, Simulink.
