Abstract
A power plant that is capable of attaining downsizing and reduction of manufacturing costs and enhancing the degree of freedom in design thereof. In the power plant, a first rotating machineincludes a first rotorhaving a predetermined plurality of magnetic poles, a statorthat generates a predetermined plurality of armature magnetic poles to thereby generate a rotating magnetic field, and a second rotorhaving a predetermined plurality of soft magnetic material elements. The ratio between the number of the armature magnetic poles, the number of the magnetic poles, and the number of the soft magnetic material elements is set to 1:m:(1+m)/2 (m≠1.0). One of the rotorsandis mechanically connected to an output portionof a heat engine, and the other of the rotorsandand a rotorof a second rotating machineare mechanically connected to driven parts DW and DW. Further, in starting the heat engine, when the rotational speed of the output portionis not lower than a first predetermined value NEST, the heat engineis started in a state where the rotational speed of the output portionis not increased.
