Implementation analysis of an elevator energy regenerative unit (EERU) for energy saving in a building

Abstract

In recent years, several processes have been taken to reserve power with a goal towards energy savings without deficiency in performance. In this, paper we improve and implement an existing invertor drive unit to achieve remarkable energy savings in elevator systems. Operation of an elevator can be classified into two modes, which are Motoring mode and generating mode. We design an energy-regenerative unit for an elevator system, which is able to feed electricity back into a power grid.
