発明の名称 (英語) WIND GENERATOR SYSTEM UPDATE
発明の概要(英語) A wind generator system (1) comprises: a windmill (10); an induction motor (20) coupled to the rotary shaft of the windmill (10); a power convertor (30) for supplying the induction motor (20) with an excitation current; a heat medium circulation mechanism (40) for circulating a heat medium which receives heat generated by the induction motor (20); a heat accumulator (50) for accumulating the heat of the heat medium; a thermal generator (60) for converting the heat of the heat medium accumulated in the heat accumulator (50) into electricity; and an armature control unit for controlling an excitation current in accordance with the power demand from a power system (100). The armature control unit performs either one or both of a power generation mode control for operating the induction motor (20) as a power generator, and a heat generation mode control for operating the induction motor (20) as a heat generator.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, fuel cell power generation system using renewable energy and attention, as one example, the rotational energy of the wind turbine generator into electrical energy with the wind power generation system has been known. Most recently, the rotation energy of the wind turbine by utilizing the heat generated by induction heating (eddy current) is converted into thermal energy and heat generation at the receiver, the heat of the heat power generation system that converts wind energy into electrical energy has been proposed (for example JP-2011-102576 Publication (Patent Document 1) and Japanese Patent Laid-Open Patent Publication 2012-43728 (Patent Document 2) the reference).
Also, for example Japanese Patent Laid-Open Patent Publication 2003-120505 (Patent Document 3) and Japanese Patent Laid-Open Patent Publication 2004-63930 (Patent Document 4) is, in the power generation system using renewable energy, a technique for enhancing power generation efficiency, and a technique to make effective use of power has been proposed. Patent Document 3 is, in the wind turbine generator, wind turbine due to the loss of the generator shaft coupling utilizing waste heat to drive the turbine, the turbine to the generator shaft coupling can be recovered as electric power for power generation, a technique for enhancing the efficiency of the device has been proposed. On the other hand, in Patent Document 4, in the power generation system using natural energy, the power generator (solar power generation, wind power generation) generated in the surplus of the electric power converted to heat in a heat storage means and is charged into (water heater), thermal energy is effectively utilized as a power generation technology has been proposed.
