Abstract: A power generating system includes a control device, a first current detection device detecting a load alternating electric current, and a second current detection device detecting a direct current of the direct current power converted by a first converter. The control device obtains a first integrated value by integrating a direct current component corresponding to a positive electric current positioned at a positive side relative to a zero-crossing of the load alternating electric current among the direct current of the direct current power converted by the first converter and detected by the second current detection device by time, obtains a second integrated value by integrating a direct current component corresponding to a negative electric current by time, and detects a direct current component included in the load alternating electric current on the basis of a degree of a difference between the first integrated value and the second integrated value.
