Desenvolvimento de Quadro de Transferência Automática para Suprimento de Serviços Auxiliares e Emergenciais de Subestações de Alta Tensão

Abstract

A solution project was developed to manufacture an automatic transfer board capable of controlling and switching three different energy sources to supply auxiliary and emergency services for high voltage substations. Aiming to meet the provisions of Module 3 of the PRODIST (Network Procedures), established by ANEEL, in addition to the provisions of Module 2 of the ONS network procedures, which establish the need for redundant sources for auxiliary substation services and the way in which these requirements must be met. Traditional solutions result in significant expenses with materials for implementation, as well as maintenance and working time. A literature review was carried out seeking to obtain more robust and effective solutions. Justifying the implementation of a system with an automated module. The result was the project to build a frame optimized in terms of cost, dimensions and functionalities, considerably reducing spending on materials, number of components, as well as working hours. The QTA presented is capable of controlling and switching three different energy sources to supply auxiliary and emergency services to high voltage substations.
