Projeto de automação de sistemas elétricos conforme norma IEC 61850

Abstract

The first automation systems used in electrical substations usually consisted of different manufactures and generations. That made integration and communication difficult between the systems, since the majority had specific protocols and in many cases owners. The IEC 61850 standard aims to standardize communication between systems and devices in electrical substations and the main objective is to ensure interoperability between IEDs (Intelligent Electronic Devices) from different manufacturers. However, the standard is not simply a new protocol. The standard specifies the IED, the network architecture, how the information should be stored and available, services available, and defines various aspects such as speed, new features and others providing a true universe of possibilities to the user. It can be noticed that there is lack of knowledge of the IEC 61850 standard requirements by most professionals. In this work will be analyzed the main possibilities suggested by the standard in order to provide professionals to acquire knowledge that allows them to develop projects in accordance with the requirements defined in the standard. Among the points defined by the standard, special attention will be given to: system planning, data models, protocols and message types, programming language and system architecture. At the end of this work will be presented the main conclusions which highlight the standard benefits and the main points of the standard that must be studied and considered in the project development.
