Abstract
As a configuration of carrying out a turning operation of a brushless synchronous power generation apparatus, there are provided a synchronous generator, an AC exciter, a rotary rectifier attached to an armature of the AC exciter, and short-circuiting means which three-phase short-circuits armature windings of the AC exciter, wherein the armature windings of the AC exciter are short-circuited, causing the AC exciter to operate as an induction motor, thus rotating the rotor shaft of the synchronous generator.
