Abstract :

This dissertation is dedicated to a comprehensive study of static synchronous compensator (STATCOM) systems utilizing cascaded-multilevel inverters. Among flexible AC transmission system (FACTS) controllers, the STATCOM have shown feasibility in terms of cost effectiveness in a wide range of problem-solving abilities from transmission to distribution levels. A cascade multilevel inverter is a power electronic device built to synthesize a desired AC voltage from several levels of DC voltages. A method is presented showing that a cascade multilevel inverter can be implemented using only a single DC power source and capacitors. To control the reactive power instantaneously, this system is modelled using the ABC transform which calculates the instantaneous reactive power. The simulation result of MATLAB/Simulink software indicates the superior performance of the proposed control system, as well as the precision of the proposed models.
