Abstract
Provided, in parallel to an electromagnetic pump in a power supply system, is an electromagnetic pump compensation power supply mechanism (10) that will perform a power-factor improving function as a synchronous machine during normal operation of a plant. The electromagnetic pump compensation power supply mechanism (10) is provided with an exciter stator permanent magnetic apparatus (45) that can switch an exciter between a non-excited state and an excited state. The exciter stator permanent magnet apparatus (45) comprises exciter stator permanent magnets (15a), springs (16) that apply force to the exciter stator permanent magnets (15a) towards positions facing an exciter rotor winding (15b), and electromagnetic solenoids (20) that make the exciter stator permanent magnets (15a) move to positions not facing the exciter rotor winding (15b) in resistance to the force applied by the springs (16).
