Two-Phase Load Modelling in Three-Phase Load Flow

Zdravko Hebel, Ivica Pavić, Marko Delimar


Currents and voltages of the power system are not only dependent on the elements of the power system, but also on the loads that are being connected onto the system. The aim of this article is to present two-phase load modelling and its implementation to the Newton-Raphson method for calculation of the three-phase load flow. The program, based on the method, had been made and was tested in the Croatian power system where one of the main causes of the asymmetry is the Electrical Traction System with a two-phase connection onto the power system through the transformer 110/ 25 kV.
