Decision support for condition-based maintenance of hydropower plants

A system for condition-based maintenance planning is being developed by ABB in cooperation with, Nybro-Bjerck, EFI, Kvωrner Eureka and some of the utility companies in Norway. The project started in 1990 and it will be finished in 1992. The project has been supported by the Norwegian Government and the utility companies’ branch organization, VR. The goal has been to establish the most salient tools and methods necessary for practical implementation of “condition-based maintenance” (CBM) in hydropower plants. For this purpose, it is established a comprehensive computer-based archive and a knowledge-based system for interpretation of measurements and observations.
