DETERMINATION OF THE CHARACTERISTICS OF THE ELECTROMECHANICAL EQUIPMENT OF THE MICRO HYDROELECTRIC POWER PLANT AT THE GUEENI SITE ON THE KOKOULO RIVER

Abstract

When setting up a small hydroelectric power plant in isolated sites, the choice of electromechanical equipment remains a very important factor. This study is part of this dynamic. Its main objective is the determination of characteristics and the choice of electromechanical equipment for the micro hydroelectric power plant at the Gueeni site on the Kokoulo River in Pita in Guinea, with a variable hydrological regime. The methodology adopted is based on knowledge of the hydraulic parameters and the hydroenergetic characteristics of the site (hydraulic power, net power). Based on these elements, we determined with great precision; the type of turbine (Kaplan), with a rotation speed (586.58 rpm); the specific speed (47 rpm); the number of generator poles (10); the electrical power of the plant (2160 kW), the apparent power of the transformer (2700 kVA) and valve closing time (1.1 s). This study is part of the dynamic of evaluating the hydroenergetic potential of small developable waterfalls in isolated areas of Guinea
