Abstract

This summary presents an approach to power converter modeling for distribution systems. The converter model is represented in single-phase forms to allow for a, b, c phase coordinate representation. A three-phase steady state model of a power converter (ac/dc - dc/ac) composed of a diode rectifier, a loss-less dc link and a pulse-width-modulated inverter is summarized from R. Stoicescu et al. (2002). Both the three-phase rectifier and the three-phase inverter are modeled as three, equivalent, Y-connected single-phase rectifiers and single-phase inverters, respectively. The model can be implemented within a three-phase power flow solver with phase representation.
