Mv Electrical Network Maintenance Strategy: a New Management Approach

Today’s power electric distribution networks in Morocco are operated in a market sector or liberation is gradual. Managers the public electricity distribution networks are required to provide a number of reliability criteria, while minimizing the total cost spent for efforts made in ensuring the assets and maintain facilities in a proper condition to avoid degradation of the infrastructure. Nevertheless, the availability of this energy for a national emergent economy is very critical, seen the geographical extent of the heritage of strategic assets of networks throughout the country. However the network implements important technical assets that were built and developed over time that we can’t their reserve all the same attention. The MV network asset maintenance activities need to be prioritized as budget and planned maintenance work time is often limited for all work to be carried out. Therefore we must identify that need priority action for reduces the number of operations while not compromising safety and efficiency and focus efforts on the minority elements which cause the majority of the harmful effects of the maintenance. However, the purpose of this paper is to present the deployment of an efficient management in order to establish a policy of optimizing maintenance resources, and to develop an approach for prioritizing maintenance work, to optimize spending, and improve the Key Performance Indicators (KPI’s) of quality of electricity supply (System Average Interruption Duration Index (SAIDI), System Average Frequency Duration Index (SAIFI) and Energy Not Supplied (ENS)). A statistical methodology is adopted to develop a systematic approach based on a multicriteria prioritization matrix, in the objective to optimize the operational management of the maintenance works.
