Abstract
A regenerative electric power storage control system for elevators, including: a converter that converts AC electric power to DC electric power; an inverter that converts the DC electric power to the AC electric power, and drives an electric motor that ascends and descends a car; an electric power storage apparatus provided, via an electric power charge and discharge unit, across DC buses located between the converter and the inverter; an electric power charge and discharge control unit to which DC electric power is supplied from an electric power charge and discharge control power supply and that controls the charge and discharge unit. The charge and discharge control unit calculates on a time zone basis electrical energy stored in and electrical energy discharged from the energy storage apparatus during a predetermined period, and based on the calculation result, determines a discharge operation for each time zone posterior to the predetermined period.
