Hybrid simulation of power quality assessment an application for power ground grid in arc furnace systems

Transient behavior in grounding systems related to electric arc furnaces might be studied using an approach to Kron's circuit model to solve Maxwell's differential equations in electromagnetic field theory. This paper presents a circuit model designed using Kron's approach implemented in ATP. The model is suitable to describe accurately the behavior of real complex grounding systems dealing with continuous operation of an electric arc furnace. Some ideas about the behavior of the power quality are evaluated by simulation of the grounding system in ATP.
