Abstract [en]

The deregulation of electric markets as well as the introduction of renewable sources of energy such as wind and wave power in several countries has lead to a demand for different operating patterns of hydro power plants. Hydro plants are more frequently operated away from best efficiency, at part-load or full-load, and with an increased number of start-ups and shutdowns. These new market conditions involve new constraints for the hydro machines, which can lead to an overall un-optimised utilisation. An example of this is Sweden, where hydro plants mainly operate Francis and Kaplan turbines built between 1950 and 1970. As a result, an extensive period of renovation has started in the country. New machines need to be designed to take into account the new market conditions.
