The invention relates to the fields of industrial automatic control system device manufacturing, intelligent basic general equipment, AI + buildings and the like in the high-end equipment manufacturing industry, in particular to an elevator power generation braking intelligent device and a traction driving elevator comprising the same. The elevator power generation braking intelligent device comprises an excitation module and a power load module. The master control circuit is used for controlling the access switch group to access the excitation module and the power load module to the three-phase asynchronous motor when the out-of-control state of the elevator is monitored, and the excitation module provides excitation current for the three-phase asynchronous motor; a rotor of the three-phase asynchronous motor rotates due to out-of-control of the elevator, and the three-phase asynchronous motor enters a power generation state and outputs electric energy outwards; the electric load module consumes electric energy and generates braking torque for the out-of-control elevator. According to the principle of asynchronous power generation of the three-phase asynchronous motor, the rotating speed of the motor is limited by controlling the output electric energy consumption of the motor, and a novel elevator braking mode is provided.
