Aplicação e análise de metodologia de posicionamento eficiente de dispositivos de proteção e manobra em rede aérea de média tensão

Abstract

The search for quality electric energy is growing more and more over the years as a result of the development of new technologies. The electricity distributors need their supply system to be protected against faults in order to meet their consumers and the requirements established in the distribution network procedures (PRODIST), since the concessionaires must present quality indicators within the standards imposed by ANEEL to in the electricity market. For the protection of medium voltage aerial networks, use is made of protection and maneuver equipment that enable the system to operate in a way that improves its reliability. The arrangement of these equipments along the medium voltage aerial network is essential for reducing the number of clients affected due to faults, and consequently reducing the FEC indicator. As a result, there is a need for efficient installation systems for protection and maneuvering equipment. In this context, the objective of this work is to apply a maximum feeder performance (DMA) methodology for the efficiency of the protection and maneuvering (DPM) systems of a medium voltage (MV) air network. The proposed methodology covers the development of an algorithm in Python programming language, considering the number of protected client parameters and fault detection in a feeder segment. The results obtained through the developed algorithm will be used to perform a comparison between the arrangement of devices proposed by the concessionaire and the proposal in this work, in order to present an efficient allocation system for the protection and maneuvering equipment obtained with higher speed. The obtained results will present a reduction of the FEC indicator.
