PURPOSE: To obtain an improved control facility for a power generation facility including a plurality of variable speed generators/motors, in which resonance and beating are prevented. CONSTITUTION: A variable speed pumped-storage power generation system including at least two variable speed generators/motors 1a, 1b being operated in parallel is split into at least two groups. Each group is controlled using different physical amounts subjected to feedback control, or different control amounts are employed in the facilities 11a, 9a to be controlled in respective groups, or both methods are combined. |
