摘　　要：针对电梯节能问题,通过控制超级电容的充放电,把电梯制动及势能所产生的能量进行储存,并在曳引设备电机电动状态时把超级电容储存的电能用直流恒流恒压的方法回送变频器直流母线,实现了不影响电网,且能高效回收利用的电梯节能控制。应用测试结果表明,该系统比原有系统节能38%以上,有应用的经济价值,亦可作为相近行业的技术参考。In view of the lift energy conservation problem, the energy generated from the lift braking and potential en- erg＇y is stored by controlling charge-discharge of the super-capacitor and then sent back to DC bus of the transducer with the method of DC constant current with the traction gear motor at the power-driven state, which can realize lift energy-saving control without affecting power grid and with high-efficient recycling. The application test result shows that the system can save more than 38% of energy than original system. The system has practical economic value, providing technical reference for similar industries.
