DeepGen IV

Alstom developed a second generation 1MW tidal turbine, with a nacelle consisting of a 3-bladed, upstream pitch controlled rotor with an epicyclic gearbox, induction generator, frequency converter and transformer. The turbine exports grid compliant power at 6.6kV via a three-phase wet mate connector mounted in the base of the turbine. The 22m long nacelle is installed onto a separate seabed-mounted foundation and weighs less than 150 tons. This tidal stream turbine has a number of notable features: First, it is simple, and easy to transport. Its buoyancy means that it is easily installed and retrieved in a single tidal cycle using small vessels, reducing installation and maintenance costs. Secondly, it has an intelligent nacelle. Thrusters rotate the nacelle to reflect the direction of the tide. Thirdly, with its efficient blades, turbine blade pitching can be altered to control load on the turbine and optimize use of the tidal conditions locally.
