Time Domain Model of Electric Arc Furnace for Study Power Quality in Industrial Networks

Original language description

The paper describes a mathematical model of the electric arc furnace in the time domain, which is designed to develop measures to improve the power quality. The model is based on a combination of Cassie and Mayer model of the arc, where Cassie model is applicable for large currents and Mayer model applies to small currents. Variable arc lengths act as excitation parameters in the model. The second part of the model focuses on the description of the furnace transformer secondary winding connected in delta and the furnace circuit. The whole system is described as a system of differential equations which solution is obtained values indicating the power quality. The model clearly states problems with higher harmonics of voltage and flicker effect. This model can be useful for designing of control algorithms of FACTS devices, where the device activity and dynamics could be simulated. As an example, the kit for improving power quality in industrial distribution network with electric arc furn
