Abstract

The present invention is a power generation system comprising a power generator and a flywheel apparatus. The flywheel apparatus has a frame, a flywheel section and an exciting section. The flywheel section has an input unit having the input shaft, first and second flywheel units having the output shaft, and first and second drive units for transmitting the rotary force of the input unit to the first and second flywheel units. The exciting section increases the flywheel effect of the flywheel section.
