Abstract

A traction elevator system is analytically simulated in this paper, driven by an induction motor, in order to study possible energy saving modes of operation in terms of returning energy to the DC link of the drive system during regenerating braking with two possible methods, i.e. with supercapacitors or with a Flywheel driven by a permanent magnet motor. The efficiency of the two proposed methods is investigated and useful conclusions are extracted.

飞轮与超级电容器在电梯节能中的比较
本文对感应电机驱动的曳引式电梯系统进行了解析仿真,研究了两种可能的运行方式,即超级电容器驱动或永磁电机驱动的飞轮驱动,在再生制动时将能量返回到驱动系统的直流环节,从而研究了可能的节能运行方式。研究了这两种方法的效率,并得出了有用的结论。
