Research on Predictive Maintenance for Hydropower Plant Based on MAS and NN

As the development of the electrical power market, the maintenance automation has become an intrinsic need to increase the overall economic efficiency of hydropower plants. A Multi-Agent System based model for the predictive maintenance system of hydropower plant within the framework of Intelligent Control-Maintenance-Management System is proposed All maintenance activities, form data collection through the recommendation of specific maintenance actions, are integrated into the system. In this model, the predictive maintenance system composed of four layers: Signal Collection, Data Processing, Diagnosis and Prognosis, and Maintenance Decision-Making. Using this model a prototype of predictive maintenance for hydropower plant is established. Artificial Neural-Network is successfully applied to monitor, identify and diagnosis the dynamic performance of the prototype system online.
