Abstract
A photovoltaic inverter, a photovoltaic power generation system and a method for controlling the photovoltaic power generation system are provided. In the method, during an anti-PID operation, only an anti-PID power supply is controlled to operate, and a voltage of a DC bus is boosted by using the anti-PID power supply, so as to suppress the PID effect. During insulation detection, both the anti-PID power supply and a target detection resistor are controlled to operate, voltages to the ground of a position of the photovoltaic inverter to which the target detection resistor is connected under different conditions are obtained by controlling the anti-PID power supply, so as to perform insulation detection by using the anti-PID power supply. Then, an insulation impedance to the ground of the photovoltaic inverter can be calculated.
