AMSC Windtec offers the SeaTitan wind turbine. The generator installed in the SeaTitan wind turbine incorporates high temperature superconductor (HTS) rotors instead of the currently used copper rotors. Using of HTS technology enables the generator to remain compact, light in weight, effective and cost efficient when compared to largecopper generators.
SeaTitan Wind Turbine
The generators employed in SeaTitan incorporate direct drive technology and do not require a gear box for execution. The integration of the generator in the turbine allows the generator to remain dissociated from the load carrying components thus reducing the chances of deformation. Moreover, the channeling of generator torque directly from the stator to the mainframe increases the power production. The HTS wires utilized in the SeaTitan wind turbine offered by AMSC Windtec contain zero DC electrical resistance, has higher temperature tolerance, requires less cooling, and 100 times more powerful than copper wires of the same proportions. The 10 MW upwind type of wind turbine incorporates a rotor with 170 m diameter and three blades. The rotor is installed over a tower measuring 120 m in height. The cut in wind speed of this turbine is 3.5 m/s, and produces the maximum power at 12.5 m/s with 10 rpm speed. For operational safety, this wind turbine stops its operations when the wind speed goes beyond 25 m/s.
The SeaTitan wind turbine operates conveniently in -10 to 40°C ambient temperature and can survive the temperature ranging from -20 to 50°C. For efficient stopping of the turbine blades, this wind turbine incorporates blade pitching power control.
