High-Efficiency 1.5MW Doubly-Fed Wind Turbine for Sustainable Energy

  The motor is a 1.5MW doubly-fed wind turbine, supporting 1.5MW variable-speed doubly-fed wind turbine, suitable for inland regional wind farms, and its improved type can be used in low wind speed, high altitude, coastal regional wind farms, and its performance meets the special requirements of low temperature rise, anti-salt spray, and low noise. The motor is installed in the nacelle, the rotor shaft at the drive end is linked to the gearbox through a coupling to receive mechanical power, the stator is connected to the grid and the rotor is connected to the grid through a four-quadrant converter. It can operate within a speed range of +/-36.7% of the synchronous speed to achieve the conversion of mechanical energy into electrical energy.
        As a key component of the wind turbine, it mainly includes, welded chassis, core winding assembly, insulated end caps, three-phase wire-wound rotor, slip-ring brush holder assembly and slip-ring chamber, stator and rotor junction boxes, sensors and auxiliary junction box device, lightning protection device, encoder and so on.
