Metodologia para a inclusão dos indicadores coletivos de continuidade no planejamento da rede de distribuição

Abstract

This work deals with the proposal of a new methodology to group reliability information and network topology with the objective of proposing works to adapt indicators of continuity to the limits established by Agência Nacional de Energia Elétrica (ANEEL). Thus, a series of steps is proposed that begins with obtaining data from the system topology and the registry of interruptions in the service, then an analysis is made of the main causes of the problems and finally evaluate works that can solve them. Also, the main interventions in a distribution system are presented and the impact of each intervention is measured on the reliability of the system, affecting the value of the reestablishment time and the number of clients affected. Finally, a case study is done of a typical rural feeder that does not present overload in the equipment nor undervoltage, being, a priori, outside the plan of works of the distributor. However, it presents Duração Equivalente de Interrupção por Unidade Consumidora (DEC), equal to 32,22 h, and Frequência Equivalente de Interrupção por Unidade Consumidora (FEC), equal to 10,71, above the limits (26,00 h and 13,00, respectively), requiring intervention in the system. It is proposed the installation of two switches in points marked by the proposed methodology, which represent 79,60 % of the DEC and 57,78 % of the FEC, adjusting these indicators to the limit stipulated by ANEEL over the 3-year horizon, reducing the DEC to 21,00 h and FEC to 6,36.
