Desenvolvimento de dashboard para estudos de proteção e seletividade em cabines primárias

Abstract

Electrical energy is essential in modern life, because it enables technological advancement and connects us globally. However, it is subject to several anomalies that can interrupt the distribuition of this energy. To overcome this, there are protection systems for the purpose of acting in a coordinated and selective manner to guarantee the intefrity of the equipment that makes up the electrical installation and isolate only the faulty componente of the network. In this context, this work presentes a tool created from Microsoft Excel, to assist in the study of protection and selectivity in primary cabins, generating coordinate charts of some protection functions for the purpose to verify the coordination of the substation’s protection equipment with the power distribution company. The interface allows the user to enter data and simulate different scenarios. Besides, it is possible export a resume of the results in .docx format, making it possible to insert data into descriptive and technical reports for Project submissions at power distribution company. To validate the developed tool, a case study was carried out with a 500 kVA substation for the purpose to verify the coordination of the equipment according to the data provided.
