This paper deals with a continuously degrading turbine runner due to cavitation that is inspected at fixed time intervals. The degradation of the system modelled gamma process. focused on comparing influence maintenance parameters long-time cost criterion. A case study, based simulated paths, shows there exists set minimize costs.

This article presents a study on the performance characteristics of Francis turbine operating with various guide vane openings to determine best point based unit quantities. The were specified width between vanes at their exit, i.e., 10 mm, 13 16 and 19 mm. characteristic curves turbine—head versus speed, torque discharge efficiency speed—were obtained input power openings. From these data, plo...
