Abstract: | The energy produced of the water fall is one the most pure; consequently, an ecological solution, preferring anywhere is possible to account the gravitational energy. The great cost price of investments are made up for in fact, of important time of exploitation of the hydro-electric plants, the cost price of maintenance is petty and for fuel are null. Today there is a high competition among he producing firms of turbines for to impose the most performance models. The solution which is proposed in this paper will improve the performances of Pelton turbine |
