Abstract :
This paper presents a new frequency domain Arc
Furnace model for Iterative Harmonic Analysis (IHA) by means of a
Newton method. Powerful analytical expressions for harmonic
currents and their derivatives are obtained under the balanced
conditions of the system. The model offers a three phase
configuration where there is no path for homopolar currents.
Moreover, it contemplates continuous and discontinuous evolution of
the arc current.
The solution obtained is validated by means of time domain
simulations. Finally, the model was integrated in a harmonic power
flow where studies have been performed in a network with more than
700 busbars and 7 actual Arc Furnace Loads.
