The invention discloses a tower crane variable frequency driving system and a control method for the tower crane variable frequency driving system, and relates to the field of tower crane control. The tower crane variable frequency driving system comprises a tower crane control system, a frequency converter module, an energy storage system and an energy storage module, and the frequency converter module comprises a frequency converter control unit, a main driving system and a driving unit of the energy storage system, the energy storage module comprises a super capacitor and a DC/DC bidirectional direct current converter connected with the direct current bus and the super capacitor, and the tower crane control system is configured to control the energy storage module and the energy storage system to store the electric energy of the direct current bus when the voltage rise of the direct current bus caused by the operation of the main driving system exceeds a preset threshold value. The tower crane variable-frequency driving system is based on a common direct-current bus technology, and regenerative braking energy is stored in a super capacitor and an energy storage system by combining the super capacitor and the energy storage system, so that waste of regenerative braking energy is avoided, and the influence of thermal pollution is reduced.
