Projeto de uma subestação com geração fotovoltaica e grupo gerador-motor em edifício comercial conectado à rede da ENEL-GO

Abstract

Following the publication of regulatory resolution 482 by the National Electric Energy Agency (ANEEL) in 2012, general conditions were established for smaller electricity producers to connect to the distribution network, allowing them to take advantage of the compensation system and enabling the consumer to generate their own renewable energy. This opened up space for a significant expansion of photovoltaic generation systems, making electricity more accessible and resulting in an increase in these installations, which must be connected to medium and high voltage systems according to resolution 414 from ANEEL. To make this type of connection possible, the implementation of electrical substations is necessary. Given the above, this work is a project for a substation connected to the medium voltage level of the distribution network and installed within the credit compensation system, powered by a photovoltaic generator unit connected in conjunction with a generator-motor group. The protection project for the equipment in this electrical substation is also included, an item of utmost importance for the safety of those served by this installation and for the healthy operation of the distribution system. The project was necessary to adapt the substation to its new operating routine with two other sources of generation. The project was developed in accordance with all regulatory norms that govern the subject and in compliance with the state of the art in the literature.
