    Abstract: The lifting device used in large mines has some obvious disadvantages of low control accuracy, poor timing performance and large power consumption. To solve these problems, the paper combines frequency control method with super-capacitor energy storage technology to improve the energy-saving of electrical system of the lifting device. With the adoption of super-capacitor energy storage technology,this design can recover and store the electric energy from the motor braking while improving control accuracy and timing performance. In some special cases, the power stored by the super-capacitor is also released to ensure the normal running of the system. The results show that the improved design of the lifting device not only increases control accuracy and timing performance under frequency control condition, but also realizes the storage and reasonable application of braking energy to meet the energy-saving requirement of the system through using the super-capacitor.
    Key words: lifting device; frequency control; energy recovery; super-capacitor; vector control
