Abstract
Official abstract text for this publication.
A wind power generating system includes: a wind mill, an induction rotating machine coupled to a rotating shaft of the wind mill; a power converting device that supplies exciting current to the induction rotating machine; a heat medium circulating structure that circulates a heat medium that receives heat generated by the induction rotating machine; a heat accumulator that accumulates heat of the heat medium; a thermal power generator that converts, into electric power, the heat of the heat medium accumulated in the heat accumulator; and an armature control unit that controls the exciting current in accordance with electric power demand of an electric power system. The armature control unit performs one or both of power generation mode control in which the induction rotating machine is operated as a power generator and heat generation mode control in which the induction rotating machine is operated as a heat generator.
First claim

1 . A wind power generating system comprising: a wind mill, an induction rotating machine coupled to a rotating shaft of the wind mill; a power converting device configured to supply exciting current to the induction rotating machine; a heat medium circulating structure configured to circulate a heat medium to receive heat generated by the induction rotating machine; a heat accumulator configured to accumulate heat of the heat medium circulating in the heat medium circulating structure; a thermal power generator configured to convert, into electric power, the heat of the heat medium accumulated in the heat accumulator; and an armature control unit configured to control the exciting current in accordance with electric power demand of an electric power system, the armature control unit configured to perform one or both of power generation mode control and heat generation mode control, the induction rotating machine being operated as a power generator in the power generation mode control by controlling to supply reactive current from the electric power system as the exciting current, the induction rotating machine being operated as a heat generator in the heat generation mode control by controlling to supply, as the exciting current, torque current causing slip that generates load torque. 2 . The wind power generating system according to claim 1 , wherein in the heat generation mode control, the armature control unit controls the torque current as direct current or alternating current. 3 . The wind power generating system according to claim 1 , wherein in the heat generation mode control, the armature control unit controls the torque current as alternating current having a frequency allowing for rated torque to stalling torque. 4 . The wind power generating system according to claim 1 , comprising a heat insulation container that contains the induction rotating machine, wherein the heat medium circulating structure circulates the heat medium in the heat insulation container. 5 . The wind power generating system according to claim 1 , comprising a power control unit configured to control electric power to be generated by the thermal power generator, in accordance with the electric power demand of the electric power system.
