The Francis hydro-turbine generator unit (FHTGU) is a typical nonlinear system with the coupling hydraulic, mechanical and electric subsystems. It challenge to understand reasons for its operational failures because major reason involves complex interactions of three Subsystems’ model interaction method normal forms has been well developed investigated, overcoming linear methods used in FHTGU’s...

Abstract The Z’Mutt pumping station, part of the Grande Dixence hydroelectric scheme, is one demonstrators XFLEX HYDRO project. A 5 MW reversible pump-turbine prototype equipped with a full-size frequency converter (FSFC) used to investigate dynamic variable speed operation in and generating mode. Since FSFC always connected electrical grid, full rotational range motor-generator can theoretical...

The state of Cameroon, faced with the situation electricity deficits, is promoting development renewable energies in general and to meet rural electrification needs particular. purpose this work study feasibility MHP Batcheu, show its contribution sustainable locality prove that it a profitable project. After study, appears waterfall Batcheu favourable establishment an installed power 260 kW op...
