Abstract-Hydroelectricity as a renewable energy to respond the increasing population and environment crisis is widely used in the world. With the Hydro Turbines/Generators (HTG) being more and more complicated, the maintenance play a more and more important role in the production management in the hydro power plant. Many researches had concentrated on the predictive maintenance for the HTG in recent years. From the perspective of data-driven, this paper reviews and summarizes the key techniques regarding data acquisition, data processing, data analysis and data mining for the predictive maintenance of HTG. Especially, it place emphasis on the data-driven models for the diagnostics and prognostics. Finally, the paper concludes the current practices and presents a future research work.

This paper presents age estimation and optimal cost preventive maintenance of carbon brush in slip ring using Weibull distribution in statistical analysis. Carbon brush is used in Sirikit hydro power plant which is electrographite brush type. Weibull distribution can find mean time to failure, failure rate, reliability with few number of the length measurement of carbon brush. It has been applied to find optimal cost preventive maintenance which reduces unnecessary planned maintenance and also increases reliability of system. These results are assessed, analyzed and compared to carbon brush maintenance guide line of Sirikit hydro power plant in Electricity Generating Authority of Thailand (EGAT) which also can apply with other power plants of EGAT.
