4.0 MW Offshore Wind Turbine from General Electric

General Electric offers 4.0 MW Offshore Wind Turbine. This wind turbine model is built utilizing a permanent magnet generator providing efficient power generation even at low level wind speeds.

The offshore wind turbine incorporates two main bearings for the purpose of transferring the axial and bending loads to the bedplate from the rotor for increased reliability. To suit the offshore working environment this wind turbine model incorporates slow speed mechanism in place of costly gear boxes.

The 4.0 MW Offshore Wind Turbine provided by General Electric incorporates a rotor with a diameter measuring 110 m and the rated capacity factor of this rotor is 52%. This rotor offers a sweep area of 9,567 m2 and it is lubricated automatically resulting in low operating expenses. The cut-in wind speed of this wind turbine is 3.0 m/s and the cut out wind speed is 25 m/s. The rated wind speed of this turbine is 14 m/s. The full power modular converter with three threads incorporated in the turbine has low weight breakers providing high level performance and needing low level of running expenses.

The bed plate yaw system incorporated in the Offshore Wind Turbine model aids in continuous wind tracking for increased power production. This model does not deploy yaw brakes and does not have any hydraulic systems thus providing higher reliability and lower operating expenses.
