Production of Energy from Renewable Sources

Hydroelectric - Hydro Screw/Coclee type
AIS Supply features Electricals and automation

A characteristic of the hydraulic screw is its simplicity, above all. Hydraulic screw works using gravity. In other words the water is driven to flow down inside the chambers from the highest to the lowest level, usually in a relatively slow way. Compare with conventional turbine systems, the hydrodynamic screw can be installed easily without modifying the natural river bed. Less excavation work compared to the same head and less building structures required. With AIS solution it is possible to install several screws in parallel and the power can reach 1 MW.

Power range 10kW to 2 MW
Scope of Supply MV cabinet and transformer (if required)
Inverter board
Supervision and Control Software
Available Technical Solutions Soft Starter No regulation of generator rpm, output frequency and voltage.
Inverter + Bypass for 1 screw Inverter + Bypass for 1 screw; upstream water level control if needed, or generator direct connection to the grid, power factor compensation. Output frequency and voltage regulation.
Inverter + By-pass for 2 screws (or more) As above, but using one inverter for two screws, power factor compensation. Output frequency and voltage regulation.
