However, it has many applications: A hydroelectric plant is capable of converting hydropower into electricity. Using the associated activities, Hydropower generation is introduced to students as a common purpose and benefit of constructing dams. For example, for a site with a maximum power output of 49.7 kW, the Annual Hydro Energy Production is calculated as follows: AEP=49.7 (kW) X 8760 (h) X 0.5 =217,686 (kWh). Based on the results of a preliminary site, investigation, a project developing 150-m gross head would be technically feasible. For example, there is a lack of hydrological data in the countries making it difficult to give comprehensive and updated overviews (); therefore, regional expertise in hydro resource assessments is poor. A 485-m penstock will also be required. Let's suppose a design discharge of 20 cumecs is delivered by a mild steel penstock of length 320m to the hydraulic turbines. Consider a typical hydro system. 1666 0 obj <>stream In order to connect the project, with the central-grid, approximately 6 km of 110 kV transmission line will have to be.
