The first part in this paper presents the steps of the design for required Static Var Compensator (SVC) system to eliminate power quality problems. The second part will discuss the dynamic model in the form of differential equation used for the EAF. The EAF model is then integrated with the SVC model to demonstrate network dynamic interactions during different operating conditions. Finally, comparison between design and actual power quality performance figures measured for actual steel making plant substation are shown at the end to validate the design values.
