Projeto de subestação para conexão de usina de minigeração distribuída em sistema de média tensão

Abstract

In 2012, ANEEL published the normative resolution 482 which established the general conditions for small energy producers to connect to the distribution networks and, later on, created the compensation system, which allowed captive consumers to produce their own energy from a renewable source. The purpose of this resolution was to encourage the use of renewable sources. With it and the several incentives created for distributed generation systems, there was a significant increase of these systems, with a focus on photovoltaic solar generation, including for mini-generation systems, with powers greater than 75 kW, which must be connected to medium or high voltage systems, according to ANEEL’s resolution 414. To enable the connection of mini-generation systems and make the voltage compatible with the levels adopted in the distribution, it is necessary to implement electric power substations. In the face of this environment, this work consists of the development of a Project for an input power substation for the connection of a photovoltaic solar plant to the distribution network, in order to monitor the development and growth of these new initiatives, related technologies and current regulations, providing the contribution to the development of minimum knowledge of these systems and energy substations for application with distributed generation, in order to maintain the integrity and continuity of these systems and their users and operators.
