摘要： In one embodiment, a flywheel power generating facility includes a flywheel power generator including a flywheel for storing rotational energy, and configured to convert the rotational energy into electric power to supply the electric power to a test facility. The generating facility further includes a driving motor configured to rotate the flywheel, and a power supply device configured to supply electric power to the driving motor. The generating facility further includes a detector configured to output a signal related to the rotation of the flywheel, and a controller configured to control operation of the driving motor, based on the outputted signal. The controller controls the operation of the driving motor so that the driving motor provides accelerating torque to the flywheel while the supply of the electric power to the test facility is stopped and while the electric power is supplied to the test facility.
