According to the traction elevator system, when accidental power failure occurs, a group control system of the traction elevator system drives one elevator through a unique standby power source, and a synchronous motor of a rising no-load elevator works in a generator mode and supplies power to other elevators so that other elevators can be rescued. The traction elevator system comprises a standby power supply; the power supply management system is electrically connected with the standby power supply and the driving system of each elevator; the group control system is in communication connection with the control system of each elevator; the communication control system is in communication connection with and controls the standby power supply, the group control system and the power supply management system; the communication control system is configured to enable a motor of one elevator in the multiple elevators to be in a generator mode through the group control system in the no-load ascending stage of the elevator, and the communication control system controls the power management system. A power management system is caused to power a drive control system of another of the plurality of elevators with power from the motor in the generator mode.
