Modelagem de uma rede elétrica de alta tensão no PS SIMUL

Abstract

This work aims to model part of a high-voltage power system using the PS SIMUL software, with the purpose of comparing the short-circuit values at the buses of interest with those calculated by the ANAFAS program, developed by CEPEL, which is considered a benchmark and reference for validation. The research encompasses the analysis of the power system to be represented, including the collection of parameters for all components, such as transmission lines, transformers, and generating sources. The PS SIMUL software was chosen due to its application in practical testing of protection networks, allowing the simulation of different types of short-circuits in modeled systems. The modeled system is located in the states of São Paulo and Paraná, comprising transmission lines of 230 kV and 88 kV, with lengths ranging from 50 km to 100 km. Performing the short-circuit study enables the design and parameterization of efficient protection schemes, as well as the specification of suitable equipment for substations and network facilities, contributing to operational safety and continuity of electricity supply. The comparison of results between the two software tools showed error rates ranging from 0.01% to 41.1%. The highest deviations were observed in short-circuits involving more than one phase, highlighting the need for greater detail and understanding of the system components in order to achieve more accurate results.
