Hydro turbine


Hydro turbines produce electricity using the potential and kinetic (renewable) energy from the falling/flowing water. The energy performance of a hydro power plant is influenced by a number of factors. For example, these may include resource and design elements such as the type of project (run-of-river vs. reservoir), the gross head, the maximum tailwater effect, the drainage area, the specific run-off, the mean and residual flow, as well as the percentage of time the firm flow is available and the flow-duration curve. Other factors also include the type of turbine, the design flow, the number of turbines, the number of jets for impulse turbines and the turbine efficiency. The energy performance of a hydro power plant will also be influenced by the maximum hydraulic losses, miscellaneous losses (e.g. transformer losses, parasitic electricity losses), generator efficiency and hydro plant availability. Refer to the Small Hydro System Description schematic for more information.

Software & Data
The RETScreen Software Hydro Power Model can be used worldwide to evaluate the energy production and savings, costs, emission reductions, financial viability and risk for central-grid, isolated-grid and off-grid hydro power (hydroelectric) projects, ranging in size from large dams with multi-turbines to small and mini hydro installations using weirs to small scale single-turbine micro hydro systems. The model addresses both run-of-river and water storage (reservoir) developments, and it incorporates sophisticated formulae for calculating efficiencies of a wide variety of hydro turbines, such as Kaplan, Francis, Propeller, Pelton, Turgo and Cross-flow models. In RETScreen, hydrological data are specified as a flow-duration curve, and costs can be estimated using an advanced formula costing method tool. The software (available in multiple languages) also includes product, project, hydrology and climate databases, and a detailed user manual.
