Zusammenfassung:	PROBLEM TO BE SOLVED: To operate a facility including an electric motor stably.SOLUTION: A power supply device includes a variation power supply including a hydraulic power generation device, and power generation amount of which varies depending on the natural environmental conditions, a non-variation power supply other than the variation power supply, a power supply section for supplying power, supplied from the variation power supply and non-variation power supply, to an electric motor, and a controller controlling to supply power, generated by the hydraulic power generation device, preferentially out of the power being supplied from the variation power supply and non-variation power supply via the power supply section.SELECTED DRAWING: Figure 3 【課題】電動機を備える設備を安定的に動作させる。【解決手段】電源装置は、水力発電装置を含み、発電量が自然環境条件に依存して変動する変動電源と、電源のうち変動電源以外の非変動電源と、変動電源及び非変動電源から供給される電力を電動機に供給する電力供給部と、電力供給部を介して変動電源及び非変動電源から電動機に供給される電力のうち、水力発電装置によって発電された電力を優先させて供給する制御を行う制御装置とを備える。【選択図】図３
