Condition monitoring of pump-turbines
2014At present, new renewables like wind, solar and marine energy are having a strong development. The generation of energy by renewables has the disadvantage that it depends on atmospheric conditions. It means that they can generate energy at any moment independently if this energy is required or not by the consumers.

Numerical Optimization of High Head Pump-Turbines
1996In order to cope with the technical challenges of high head pump-turbines, new methods like simultaneous engineering and numerical studies are required. In this paper the application of simultaneous engineering is shown with an example, as well as typical pump-turbine concepts and design features.

Transient Analysis of Variable-Pitch Pump Turbines
Journal of Engineering for Power, 1967A method of analyzing the transient behavior of a pump turbine with variable-pitch blades is presented. A series of equations that describe the behavior of the unit during the transient period is found by interpolation of the unit’s characteristic. These equations are combined with the method of characteristic solution to the waterhammer equations to ...
