Power output joint debugging device of photovoltaic inverter

The invention relates to a power output joint debugging device of a photovoltaic inverter. The power output joint debugging device of the photovoltaic inverter is provided with two input ends and one output end. The input ends are connected with an output and a gate counting point of the photovoltaic inverter of a photovoltaic power station respectively, and are respectively used for detecting active and reactive momentary values or stage total quantity output by the photovoltaic power station and the actual power factor and the active and reactive momentary values or stage total quantity of the gate counting point. The output end is connected with the photovoltaic inverter in the photovoltaic power station. The power output joint debugging device of the photovoltaic inverter generates an adjusting instruction for the inverter, and the output of the inverter is changed according to the adjusting instruction so that the power factor of the gate counting point can meet the requirement for grid connection. The electrical parameters such as the power factor of the gate counting point are analyzed and are combined with the electrical parameters of the output of the inverter, and the output adjusting instruction is given to the photovoltaic inverter, so that the power factor of the gate counting point is within the acceptable range. An SVG device and a large value capacitor are not required, and the power output joint debugging device of the photovoltaic inverter has the economical efficiency of popularization and application.
