Research and Application of Elevator Energy-Saving Devices with Super Capacitor to Store Energy

摘要

For the problems of complex control and harmonic interference when elevator's regenerative braking energy feed back to the grid, The paper presents an energy saving program. Renewable energy is stored with super capacitors and used locally. The paper analyzes the basic operating principle of the super-capacitor energy storage device and power operation curves in different conditions. The elevator energy consumption experiments are completed in five typical working conditions. Experimental results show that super capacitor energy storage device of the elevator is stable and has a good energy saving effect.
