Abstract

In this paper, the failure number of hydroelectric power equipments in the whole life is predicted based on Crow-AMSAA Reliability Growth model. Considering influence of preventive maintenance to failure rate, service age reduction factor E is introduced to adjust service year of equipment and the maintenance cost model of hydroelectric equipments in the life cycle is derived. The optimal preventive maintenance period with minimum operation cost has been found. A new method to determine the cycle of the timed preventive maintenance for hydroelectric equipments has been proposed in this paper, which will be useful for maintenance management of electric power equipment.
