Study of the Sizing of the Small Hydroelectric Power Station of the Gueeni Site on the Kokoulo River in Pita (Republic of Guinea)

In the Republic of Guinea, the supply of electrical energy is still a major issue throughout the country, especially in rural areas. However, the hydroelectric energy potential of Guinea is enormous, 6000 MW, with a very dense hydrographic network (1165 rivers), which originates mainly in Fouta-Djalon. To date, only 5% of this potential has been developed and only benefits nearly 10% of the Guinean population. This study is part of this component for the improvement of electricity supply in isolated areas of the country. Its objective is to assess the hydropower potential and determine the electromechanical parameters of the Gueeni waterfall equipment on the Kokoulo River in Pita. The main results obtained are: river water flow (9.781 m3/s), gross head (31 m), net head (28.264 m), hydraulic power (3000 kW), net power ( 2700 kW), the type of turbine (Kaplan), the rotational speed of the turbine (586.58 rpm), the number of poles of the generator (10), the electrical power (2160 kW), the apparent power of the transformer (2700 kVA) and valve closing time (1.1 seconds). These results represent important elements for the establishment of the small power plant at the Gueeni site. Keywords: Small power plant, Electromechanical equipment, Hydroelectricity, Pita, Guinea
