What is it about?
This paper presents detailed calculations of voltage and current harmonic distortions emitted from an electric arc furnace load in a modified 14-bus Cigre benchmark distribution network. Individual harmonic components and total harmonic distortions are calculated according to the IEEE 519-2014 standard. Different conditions to perform the harmonic studies such as time of measurement, window duration and multiplying factors are considered. The studied arc furnace is connected at bus 14 in the modified 14-bus Cigre benchmark through a step-down transformer. The stochastic voltage-current characteristics of the arc furnace are modelled by a hyperbolic equation and the random variation of the arc length is simulated by a white noise signal. MATLAB/Simulink is used to simulate the arc furnace system and the detailed calculations of voltage and current harmonics are presented, including analysis of individual and total harmonic distortions at all buses.
