Abstract :
This paper presents a power-converter model intended for balanced and unbalanced radial power-flow studies. A three-phase steady-state model of a power converter (AC/DC-DC/AC) composed of a diode rectifier, a lossless DC link, and a pulse-width-modulated inverter is presented. 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 is implemented within a three-phase power-flow solver with phase representation. Simulation results on a balanced and an unbalanced 15-bus system are presented.
