CONTROL DEVICE OF HYBRID DRIVE TYPE ELEVATOR

摘要

PROBLEM TO BE SOLVED: To suppress efficiently the total power consumption of a whole elevator system by using the electric storage devices of different elevators in common to one another.

SOLUTION: A control device of a hybrid drive type elevator includes a power accumulation changeover device 62 which is interposed between an electric storage device 30a installed in an elevator 10a and an electric storage device 30b installed in another elevator 10b and adjusts the voltages of the power supplying lines of the two elevators 10a and 10b to the same level. A power accumulation integrated control device 61 installed in a group control device 60 judges the surplus or the lacking condition of the electric power from the voltage variation in the power supplying lines and performs the charge/discharge control to the electric storage devices 30a and 30b integrally. This allows suppressing efficiently the total power consumption of the whole elevator system by using the electric storage devices 30a and 30b of the elevators 10a and 10b in common to one another.
