摘要： In a wind-powered thermal power generation system, an induction motor includes a field (rotor) which has a field core coupled to a rotation shaft of the wind turbine and a field conductor, and an armature (stator) which has an armature core arranged on the outer side of the field with a spacing therebetween and an armature winding, and the induction motor is housed in the heat insulating container. A heating medium circulation mechanism circulates, inside the heat insulating container, a heating medium that receives heat generated by the induction motor. A magnetic field control means controls an input current to the armature winding so as to result in slip that produces load torque at the rotor rotating due to rotation of the wind turbine. A power generation portion converts, into electricity, the heat of the heating medium heated by the induction motor.

摘要： The induction heating device that heats a heating medium includes a rotor having a rotation shaft, a heating part disposed to be opposed to the rotor at a distance, a magnetic flux generating part provided at the rotor to generate magnetic flux for the heating part, and a flow passage provided along the heating part to allow the heating medium to circulate. The flow passage has an inlet to supply the heating medium on one side in a direction along the heating part and an outlet to discharge the heating medium on the other side. The distance between the magnetic flux generating part and the heating part is larger on the outlet side than on the inlet side of the flow passage.

摘要： An electric power generation system includes a wind turbine, a conductor rotating as the wind turbine rotates, a heat transfer medium vessel, a magnetic field generator, a heat accumulator, and an electric power generation unit. The magnetic field generator is operated to generate a magnetic field and therein the conductor is rotated and thus heated through induction, and the conductor's heat is transmitted to the water in the heat transfer medium vessel to generate steam which is in turn supplied to a steam turbine and thus drives an electric power generator to generate electric power.
