Influence of the vortex rope location of a Francis Turbine on the hydraulic system stability

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Philippe Allenbach, Basile Kawkabani, Sébastien Alligné

Hydroelectric power plants are known for their ability to cover variations of the consumption in electrical power networks. In order to follow this changing demand, hydraulic machines are subject to off-design operation. In that case, the swirling flow lea ...

A Low-Rate Identification Method for Digital Predistorters Based on Volterra Kernel Interpolation

A novel identification and digital predistortion scheme of weakly nonlinear passband systems such as RF power amplifiers (PA) is presented. It is well known that for the identification of weakly nonlinear systems, despite the spectral regrowth, it suffices ...
