Control method, system and equipment for potential energy recovery of crane equipment and storage medium

The invention relates to a control method, system and equipment for potential energy recovery of crane equipment and a storage medium, and relates to the technical field of potential energy recovery, and the method comprises the steps that a control module configures a potential energy recovery voltage upper/lower limit based on a braking chopping voltage upper/lower limit, and the braking chopping voltage upper limit is larger than the potential energy recovery voltage upper limit; the braking chopping voltage lower limit is smaller than the potential energy recovery voltage lower limit; when it is detected that the real-time voltage of the direct-current bus of the frequency converter is larger than the potential energy recovery voltage upper limit, the control module adjusts and controls the DCDC module to charge the energy storage module through the current loop based on the preset charging current; and when the real-time voltage of the direct-current bus of the frequency converter is detected to be small
