Abstract:
    A generator of telescopic double-rotor wind-electricity exciting type is prepared as setting permanent magnet internal rotor (PMIR) on sub-driving shaft of generator and ring form rotor (RFR) on master driving shaft of generator, enabling RFR to rotate around PMIR, setting number of pole-pair on internal winding and external winding at RFR to said internal rotor and stator winding separately to be Pe pair-pole and Pg pair-pole, connecting external and internal winding of RFR to be reverse phase sequence, connecting yawer and rotary speed measurement units on wind master wheel and wind sub-wheel to central control unit.
