Abstract When the potential energy load driven by the motor of the crane mechanism is lowered, or the motor is in the state of regenerative power generation, the generated regenerative energy is consumed through an external braking resistor.Forthe problem ofenergywaste, a technique of applying public DC bus energy feedback variable frequency speed regulation system to the crane is proposed, and the regenerative energy generated by each mechanism is fed back to the power grid through the active inverter device, which solves the waste of energy, has no pollution to the power grid, and improves the control performance of the speed control system.
