Abstract:
    A exciting control system of wind-driven generator is prepared as setting wind master wheel with stator on master driving shaft of wind motor and setting wind sub-wheel used for driving permanent magnet external rotor on sub-driving shaft of wind motor, utilizing double-rotor structure of brushless double-feed motor rotor and rotary permanent magnet external rotor to realizing variable speed and variable frequency operation of generator set for reducing half of generator number of pole-pair comparing to the same capacity generator with single rotor.
