Abstract :
This paper seeks to revise the concepts related to the overexcitation relaying in synchronous generators for hydro power plants and its coordination with the V/Hz limiter of the automatic voltage regulator (AVR). The methodology for the ANSI 24 protection function set up in hydro power plants is revisited. Finally, problems faced during the commissioning of a power plant in Brazil is discussed.
