Análisis de corto circuito considerando cargas

Abstract

Short circuit analysis is usually simplified neglecting shunt connections including system loads. If under particular conditions, system loads cannot be neglected, the superposition principle can be used, adding pre-fault currents to fault currents. The analysis presented in this paper considers system loads. Internal voltages and Th6venin methods are used in the short-circuit analysis and are illustrated in a line-to-ground fault problem. Loads are represented by two different methods under node voltages fluctuations, as constant impedances and constant current loads.
