This paper presents a dynamic model of an electric arc furnace (EAF) developed in Matlab/Simulink environment. Model is based on simulating varying resistance of the electric arc in time-domain while taking into account its stochastic behaviour. The model was applied for estimation of voltage flicker in power transmission network at the point of common coupling caused by operation of EAF. Modelling...
25 kV, 50 Hz single-phase AC supply has been widely adopted in the long-distance electrified railway systems in many countries. Electrical locomotives generate harmonic currents in railway power supply systems. Single-phase traction loads also inject large unbalance currents to the transmission system and cause voltage unbalance subsequently. As the amount of rail traffic increases, the issue of power...
