LOAD FLOW, THREE-PHASE SHORT-CIRCUIT AND DYNAMIC ANALYSIS STUDIES IN ELECTRICAL POWER SYSTEMS

Abstract

INTRODUCTION: The study of load or power flow in electrical systems is essential to design the infrastructure and predict the required voltages, currents and powers. The 2018 IEEE Std 3002.2 standard (IEEE, 2018) allows you to simulate situations that could hardly be safely tested in the real world. In addition, this type of analysis makes it possible to identify problems related to system loss, loading of new equipment, and other occurrences. One of them is the occurrence of faults in electrical systems that result in large variations in the currents and voltage of the three-phase network. Thus, dynamic analyses allow the study of short circuits in these systems while statistical analyses focus on the charge flow. This discussion is based on standardized technical norms to obtain a reliable theoretical basis for the procedures used in academic studies on this important topic of electrical engineering.
