Resumo
O atendimento comercial aos clientes de uma empresa de distribuição de energia elétrica (DEE) tem como principais ordens de serviços: o religamento de consumidores, corte de fornecimento, atendimento de clientes novos, solicitações dos clientes, entre outros. Para cumprir as ordens de serviços comerciais, as empresas de DEE possuem um grupo de viaturas e equipes de manutenção, localizadas em diversos pontos da cidade, prontas a atender as ordens de serviços comerciais. Os despachos dinâmicos de viaturas para o atendimento das ordens de serviços nas redes de DEE estão dentro da classe de problemas chamados “Alocação Generalizada” e podem ser modelados como problemas de programação linear inteiro-misto (PLIM), e dependendo das ordens de serviços, o número de viaturas e as restrições do problema podem ser considerados de grande porte. O presente trabalho desenvolve uma metodologia para a automação dos despachos dinâmicos com deslocamento de viaturas e suas equipes para o atendimento das ordens de serviços. O objetivo desta metodologia é hierarquizar o conjunto de ordens de serviços e atribuí-las a todas as viaturas disponíveis, segundo os critérios considerados pela empresa de DEE no período de trabalho diário e horas extras se fossem necessárias, abrangendo assim a maior quantidade de atendimentos possíveis com a consequente diminuição do tempo de duração das interrupções e a melhora do indicador coletivo DEC (Duração Equivalente de Interrupção por Unidade Consumidora) de acordo com as metas estipuladas pela Agência Nacional de Energia Elétrica (ANNEL). A metodologia proposta foi testada na área de concessão da Rede de Energia Caiuá na cidade de Presidente Prudente para dois casos básicos, considerando um 50% de ocorrências emergenciais e obtendo-se no primeiro caso...
The comercial attendance to clients of a company distribution of electrical energy (DEE) has as main service orders: reconnection of consumers, cutting the supply, new clients attendance, request from clients, among others. To meet the orders of commercial services the DEE companies have a group of vehicles and maintenance equipment, located at defferent points of the city, ready to meet the orders of commercial service. The dynamics dispatches of vehicles to the attendance of the orders of services in networks of distributions of electric power are within the general allocation problem and can be modeled as a linear programming problem mixed integer (PLIM) and depending on the services orders, the number of vehicles and the constraints of the problem can be considered large scale. The present work develops a methodology for automation of dynamic dispatch with displacement of vehicles to meet the orders from commercial services. The objective of this methodology is the set of hierarchize orders of commercial services and assign them to all vehicles available, according to the criteria considered in the daily work period and overtime if the were necessary (in case of emergencies attendance) so as to cover the most possivel amount of attendances with the consequent reduction of time duration of the interruptions and improving the collective indicator DEC (equivalent duration of interruption per consumer unit) according to the targets stipulated by the national electric energy agency (ANEEL). The proposed methodology was tested in the concession area of the power grid Caiuá in the city of Presidente Prudente for two basic cases, considering one 50% emergency occurrences and obtaining in the first case a total number of attendances, covering all emergency attendances, generating minimal expense to the concessionary. In the second case... (Complete abstract click electronic access below)
