A single phase PSCad electric arc furnace model

Electric Arc Furnaces (EAFs) are among the larger loads imposed upon the electrical grid. The size of these loads, when combined with the stochastic nature of the electric arc, and the poor reaction of the grid to such loads, makes the EAF worthy of study in general and modeling in particular. The present work develops a model of an EAF that is designed as a custom component for use with the PSCad modeling software but can be used equally well in real-time simulation systems. The model is single-phase, allowing multiple instances to be connected in any configuration so that unbalanced situations can be easily simulated. The model is completely documented so that it can be duplicated with no additional information.
