SAE SeaGen-S 2MW

The SeaGen-S 2MW tidal generation system evolves the highly successful 1.2 MW SeaGen-S device that was operational in Strangford Lough for 8 years. The SeaGen-S tidal consists of a twin 1 MW tidal turbine trains mounted each end of a crossbeam which in turn is supported by a surface piercing tubular steel tower. The cross beam can be raised, as required above the sea surface to maintain the drive trains, avoiding the cost and delay associated with expensive marine vessels.
The horizontal axis rotors use an active blade pitching system which limit structural forces during high flow conditions. This allows the use of blades that are highly efficient over a range of tidal speeds, from average cut-in speeds of about 1 m/s to rated flow achieved at about 2.5 m/s. Energy capture is further enhanced by variable speed operation which allows the turbine to operate at its optimum tip speed ratio (all the way up to up to rated power) and also minimizes the dynamic loads on the transmission system.
