Sistemas multi-agentes aplicados a prote??o adaptativa de linhas de transmiss?o com três terminais

摘要

This paper discusses the adaptation of the settings of distance relays for three-terminal lines employing agents. Agents are software processes capable of searching for information in networks, interacting with pieces of equipment and performing tasks on behalf of their owners (relays). Results illustrating the performance of the adaptive method proposed, compared to conventional fixed settings, are presented. It is shown that the digital relays and agents acting within a communication structure can alter adaptive settings to ensure correct performance over a wide variety of operation conditions. The proposed relaying scheme can also be utilized for transferring the trip of the first zone, clearing over the entire line.
