Dam turbine

hydraulic

Exploits the hydraulic resources of valleys using modular installations with Kaplan turbines. These installations are based on the construction of a series of micro-dams along the valley, instead of using one large dam, and so minimise the civil works involved. :: GENERAL CHARACTERISTICS The modular installation can hold one or more Kaplan turbines of 250 kW, which each require a flow rate of just 10 m3/s and a 4 metres jump. The pressure head required for optimum operation of these hydraulic pumps can be achieved with a small dam with a metal sluice gate operated by hydraulic systems. :: BENEFITS • Consecutive micro-dams instead of large dams. Reduced medioambiental impact. • A single model of turbine (semi-Kaplan or Kaplan, 250 kW each, in a self-priming siphon configuration) • Minimum civil works • Non-floodable above-water generators • Machinery installation structures with a catwalk, for improved access between opposite banks • The water only rises to the overflow level • Improves water infiltration into the subsoil • Improves fish fauna • It represents a watershed microregulation
