Summary:The invention provides a rapid power tracking method for a photovoltaic cell panel. The method comprises the steps that a power instruction needed by a load is obtained, an original tracking loop is shielded, a voltage set value needing to be adjusted for tracking is calculated, the voltage set value of original tracking is set to be a recalculated voltage set value, and the voltage set value is put into the tracking loop again after a bus is stable. According to the rapid power tracking method for the photovoltaic cell panel, the active power adjusting speed of a photovoltaic inverter is increased, and the input is rapidly tracked to the required power value. 本发明提供了一种光伏电池板快速功率跟踪的方法，获取负载所需功率指令，屏蔽原跟踪环路，计算跟踪需要调节的电压给定值，将原跟踪的电压给定值设置为重新计算出的电压给定值，至母线稳定后重新投入跟踪环路。本发明所述的光伏电池板快速功率跟踪的方法提高了光伏逆变器的有功调节速度，使输入快速跟踪至需要的功率值。
