This paper proposes the unique wind turbine system, which is composed of the tandem wind rotors and the peculiar generator with the inner and the outer rotors, and discusses the wonderful advantages of the system. The large-sized front wind rotor and the small-sized rear wind rotor drive respectively the inner and the outer rotors of the generator, in keeping the rotational torque counter-balancing. Such operating conditions enable to make the cut-in wind speed slower and to keep the frequency/output constant irrespective of the wind speed, without the conventional breaking and/or the pitch control mechanism.
