PROGRAMA PARA CÁLCULO DE CORRENTE DE CURTO-CIRCUITO

Abstract

A Electric Power System - SEP is a complex mesh consists of a Generation Network, Processing, Transmission and Distribution of Electric Energy and aims to engage the operation, control, maintenance, management and other operational processes and related uses this energy produced by sector, through different processing procedures, transmitted at high voltage and distributed under the most diverse operational forms. With size and characteristics indicating that it unique worldwide, the system of production and transmission of electricity in Brazil is a large hydrothermal system, with a strong predominance of hydroelectric plants and multiple owners who require high standard of technical competence, synergy between the teams and the definition of guidelines and strategies. Given these facts, the power electric system is susceptible to electrical failures caused by many reasons, these failures commonly called "short circuit" or "faults" that occurs most often in transmission lines due to their exposure and extension. This work aims to solve the problem of a three-phase short circuit that occurs in bar 2 and a Phase-Earth short circuit in bar 4, and thus get all the nodal tensions inherent in each bar after the fault occurrence. Once all the necessary information, the work was completed with the development of an algorithm to perform calculations quickly and effectively short-circuit current using the method of symmetrical components in three-phase systems in transmission lines after the entry of network parameters to be analyzed.
