RESUMO

This research presents the development of an adaptive digital distance protection system by a multi-agent system (MAS). This MAS will work in a distributed way, with expert entities (agents) inserted in specific places and acting efficiently in the solution of local problems. With the application of the MAS, the distance relays will have desirable characteristics, which are difficult to be reached by conventional techniques. Among the deficiencies observed in conventional protection systems, there is the insensitivity to the dynamics of the electrical power system due to changes in operating conditions. So, there is the necessity of a protection system which is more flexible, selective and effcient to assure reliability and continuity in the electricity supply. To improve these characteristics, several computational simulations were done using alternative transients program (ATP) to generate the desirable adaptive operation curves. These curves, when inserted into a database, will represent the expected changes in the operating conditions of an electrical system. For the implementation and validation of this approach, several tests were done with the purpose of comparison of this approach (using MAS) to the traditional philosophy of distance protection. The results obtained are promising and demonstrate a highly satisfactory degree of accuracy and reliability of the proposed method.
