Plano de manutenção civil para gerenciamento de pequenas centrais hidrelétricas

Abstract

The lack of maintenance in the civil structures of a small hydroelectric plant can cause failures that prevent the generation of electrical energy. This work addresses the topic of civil maintenance in small hydroelectric plants due to the occurrence of power generation shutdowns in plants located in the state of Minas Gerais due to the lack of preventive maintenance in their structures. The objective of this work is to develop a civil maintenance plan for small hydroelectric plants. To achieve this objective, the energy generation histories of eighteen small hydroelectric plants were analyzed, where data on plant shutdowns that occurred due to lack of maintenance of civil structures were obtained. In addition, a maintenance study focused on reliability was carried out for the plant's civil structures to support the preparation of the civil structure maintenance plan. From this study, a list of activities to be covered by the maintenance plan was created. A civil maintenance plan for small hydroelectric plants was presented.
