Zusammenfassung:	A method for generating current and voltage for a photovoltaic power generation system is provided, including: detecting an original current of an MPPT unit; in a case that the original current is greater than or equal to a preset current, controlling the adjustment module to reduce the original current of the MPPT unit; scanning the MPPT unit to determine a scanned current and a scanned voltage of the MPPT unit; obtaining an adjustment current and an adjustment voltage of the adjustment module; adjusting the scanned current and the scanned voltage according to the adjustment current and the adjustment voltage; and generating a current-voltage curve according to the adjusted scanned current and the adjusted scanned voltage. Thus, an overcurrent protection function of the MPPT unit is not triggered in a case of a large current, and thereby a complete current-voltage curve of the photovoltaic power generation system can be obtained.
