SUMMARY OR ABSTRACT
Text of Note
Reducing the size and weight of a power electric system is a prodigious challenge to researchers as the development of the latest technologies emerge in the field of electrical engineering. A similar urge is there to develop a light-weight mobile power substation (MPS) to use in the electric power distribution systems during emergency conditions. This thesis proposes a power electronics based solution using the modular multilevel converter (MMC) topology to design the MPS system. The market-available power semiconductor devices are analyzed and suitable devices are selected to design the system. The phase-shifted pulse width modulation (PS-PWM) and selective harmonic elimination (SHE) switching algorithms are selected to modulate the MMC terminals. To validate the proposed techniques simulation files are built in MATLAB/SIMULINK™. Simulation results are presented and analyzed to verify the theoretical claims. These simulation results prove the feasibility of designing the MPS system with the proposed techniques.
