To generate electricity having a frequency that coincides with the frequency of the electricity of a power system by a windmill of the low number of revolutions while omitting as much as possible the use of a gear and a frequency converter.
This wind power plant comprises first to n-th windmill rotors and first to n-th generators that output first to n-th multiphase AC voltages. The i-th generator comprises stators to which the i-th to first multiphase voltages are fed from the i-th to first generators, a rotor that rotates integrally with the i-th windmill rotor, and a voltage output mechanism. Each of the stators comprises a stator winding that generates a rotating magnetic field rotating in the direction reverse to the rotative direction of the rotor by using the i-th to first multiphase AC voltages. The rotor 7-i comprises a rotor conductor with which the rotating magnetic field crosses. The rotor conductor and the stator winding function as induction machines.
