Arc Flash Study in large scale industrial plant with internal generation and complex interconnected network

This Poster present a comprehensive and hierarchical procedure for Arc Flash Study in complex large scale industrial plants with internal generation. All steps of study including Model development, Model validation, arc flash study and result analysis and debugging tips in each stage are discussed in details. In model development the equipment and important parameters which can affect the study are deliberated. In addition, significant points and challenges regarding load flow and short circuit study which are required to validate the developed model are covered. Then parameter, standards and setting which are necessary to be taken into account for the Arc Flash Study are introduced. Finally, the result analysis approaches and all the possible mitigation methodologies to decrease the incident energy in high category switchgears are presented.
