Development of Advanced Unbalanced Power Converter for AC DC Power Distribution System

With the rapid demand of electricity, the installation of power electronics based equipment in power distribution system has grown rapidly for ac dc system coupling, system protection, alternative energy source interface, etc. This paper focus on power electronic component and system modelling techniques and three phase ac dc power flow analysis for power distribution systems. The research discusses the models that are developed for unbalanced power electronic converters, such as thyristor converters, diode rectifiers, and Pulse Width Modulated PWM converters. The modelling approach captures the imbalance of distribution systems using three, delta connected, single phase converters. To perform system analysis, these models have been incorporated into two types of ac dc power flow solvers A three phase backwards forward sequential solver and a three phase unified solver using the modified nodal analysis method. Both solvers have been applied to unbalanced radial and weakly meshed distribution systems. Finally, an ac dc system hardware test bed was created to validate the proposed models and the performance of the power flow solvers. Extensive hardware tests, time domain simulations, and steady state analysis have been performed.
