Desenvolvimento de um gateway configurável para conversão de dados de equipamentos modbus de subestação de média tensão

Abstract

Substation automation is essential to ensure the efficient and safe operation of the electrical system, in addition, obtaining and analyzing accurate and real-time data from substations is essential for strategic decision-making. A configurable gateway will allow access and efficient conversion of ModBus equipment data, providing valuable information for operators and engineers in the management and maintenance of the electrical system. This work is based on the IEC 61850 and IEC 60870-5 standards, in which the IEC 61850 aims to establish standards for communication and automation of electrical power systems, defining a set of communication protocols, often used in substations for communication between devices and systems. The IEC 60870- 5 standard aims to specify the communication protocols for supervision and control systems in substations in general, which is used for data acquisition and remote control of substation equipment. Part 101 of the IEC 60870-5 standard provides detailed guidelines on how the ModBus protocol should be implemented to ensure reliable and efficient communication in substations. It describes message formats, the structure of data packets, transmission modes, error detection and correction methods, and other relevant technical.
