Interactive transient analysis of unsymmetrical faults in industrial plants

Abstract

This paper describes an interactive graphical program for the calculation of symmetrical and unsymmetrical faults in industrial networks, like the ones found in oil refineries. The load of these networks comprises a large number of induction motors, special consideration is therefore given to their simulation, including an efficient method for aggregation. Sample results from studies performed on a realistic system are presented and general conclusions are drawn.
