The invention relates to an elevator control system and an operation method thereof, in particular to a multi-tractor synchronous control system and an operation method thereof. The multi-tractor synchronous control system is quick in emergency response, high in safety and high in speed. A first sensor module is arranged on a power module and connected with the control system. The power module comprises an alternating-current power source and a rectifier module, and the alternating-current power source is connected with the rectifier module which is connected with the control system. The first sensor module comprises a first current sensor and a first voltage sensor, and the first current sensor is arranged at an output end of the rectifier module and connected with the control system. Operating speed of an elevator car can be effectively increased to save waiting time, reliability of the system is improved, the number of tractor braches can be regulated at any time according to load conditions, and accordingly high efficiency and energy saving are realized.
