The floating wind turbine platform also includes a tower having mounted in vertical alignment over one of the columns, a turbine rotor coupled to an electrical generator mounted proximate to the upper end of the tower, main beams interconnected to the stabilizing columns, and water-entrapment plates attached to the lower ends of the stabilizing columns. The floating wind turbine platform further includes a ballast control system including an alignment sensor configured to detect a rotation of the tower, and a controller coupled to the alignment sensor for directing a transfer of the ballast from an internal volume of one column to another column upon the alignment sensor detecting rotation of the tower to adjust a vertical alignment of the tower.

摘要： Wind turbine rotational system having several drives and a central control system (CCS), each drive comprising a motor, an electronic converter and an actuator. The CCS sends speed and torque setpoints to the electronic converters which drive the motors according to said setpoints. Operation of the system comprises: designating a drive as master and the other drives as slaves; designating, for each slave, one of the drives as reference drive; the CCS determining master speed and torque setpoints, and sending them to the master; the CCS obtaining real torque of the master; CCS obtaining real speed of each reference drive; and the CCS sending to each slave a slave speed setpoint equal to the master speed setpoint, and a slave torque setpoint equal to the real torque of the master plus a variable offset based on a difference between the master speed setpoint and the real speed of its reference drive.

摘要： A wind compressor system having one or more wind turbines and a plurality of wind compressors located proximate the one or more wind turbines. The wind compressors optimize the energy created by the wind turbines by redirecting and converging the wind from the wind compressor to the wind turbines. Each of the wind compressors comprises an obstruction having a size and shape adapted to converge the wind currents by means of a Venturi effect toward the one or more turbines thereby increasing the velocity and force of the wind hitting the wind turbine. A plurality of transporters coupled to the wind compressors. The transporters configured to move at least one wind compressors to a location that maximizes the force of the wind encountered by the turbine.
