Implementação de um sistema de proteção, automação e controle virtualizado para subestações digitais baseado na Norma IEC-61850

Abstract

This document addresses the evolution of information technologies in the transformation of power substations, considering the increase in renewable sources and the complexity of the modern electrical grid. To meet these challenges, the concept of Centralized Protection, Automation, and Control (Virtual PAC) was adopted, based on smart grids and the IEC 61850 Standard. Virtual PAC involves the virtualization of protection and control devices in the substation, making them hardware-independent, thus achieving greater flexibility and cost reduction in maintenance. The contributions of this work include the design and implementation of the PAC system described above, with a focus on creating virtual IEDs that perform protection and automation functions, as well as a virtual simulator/controller for basic a testing the standard’s protocols. The results showed response times with low latencies similar to physical equipment, indicating promising expectations for this new virtual approach.
