Implantação do Sistema de Rejeição de Cargas (SRC) no Sistema Elétrico de Potência (SEP) da Hydro Alunorte

Abstract

The study presents the implementation of a Load Rejection System (LRS) at Hydro Alunorte to preserve internal power generation and partial production during external power failures. The LRS, using frequency relays, automatically sheds non-priority loads, ensuring the continuity of utilities (water, steam, and compressed air) and minimizing financial losses. The system was successfully tested in real events, demonstrating its effectiveness.
