The invention discloses an energy-saving operation system for elevator for restraining a total power of a plurality of elevators at each time span and reducing adverse influence to passengers (reduce declining of service quality of operation) and controlling the operation of the elevators. The invention herein comprises a power profile calculation apparatus (203) based on at least one of the following information, such as direction of the elevator car, calls in elevator hall, calls in elevator car, number of passengers, and passage flow in the building, for calculating the time-dependent behavior of usage power value of each elevator. The invention herein also comprises a power restraining value calculation apparatus (204, 205, 211) which gives a total power restraining value which is below a valve value based on a total power profile calculation, and calculates the total power restraining value which serves the power restraining value of each elevator. Each elevator consequently operates energy-saving running based on power restraining value of each elevator. |
