Description

The focus of this paper describes the designing procedure of Small hydro power plant implemented in Restelica River, Kosovo. For normal operation of the Small hydro power plant, there must be done measurements of the river basin annually water flow, hydraulic net head of water, to calculate sustainability of water flow, flow duration curve, flow rate, configuration units depending on flow rate etc. The choice of the turbines was made depending on head and flow rate of water from which has resulted in the installation of different turbines that have fit better those conditions. The head losses in penstock are estimated to be in the percentage (%) of the hydraulic gross head, depending on the length of the penstock, its diameter, sustainability of flow rate and its velocity. Since the water flow, it's not stable enough for production 3.018 MW electricity from one turbine, in this case, are proposed to installing three different turbines. This paper aims to determine the best efficiency of Small hydro power plants SHPP Restelica 1,2 and 3, with three turbines during operation depending on rated discharge per unit. If we rely only on the gross level of water drop in the respective turbine, then for all three power plants, Restelica 1, 2 and 3, it follows that the most favorable turbines will be those of Francis. But when optimizing a particular type of turbine for a particular location, one must also consider the amount of water that will pass through the turbine in question.

Keywords:

Francis turbine, efficiency, biodiversity, water flow, water head, power, sustainability.
