Abstract :
This paper analyses the load harmonic modelisation under unbalanced conditions. It presents a harmonic characterization of linear three-phase loads (three-phase P-Q consumptions) for different impedance configurations and analytical models for an ideal six and twelve-pulse converter supplied by unbalanced voltages, too. The models of these linear and nonlinear loads are incorporated to the three-phase harmonic load flow formulation. A 15-bus network is presented to study the different load behavior
