Abstract: The 350MW supercritical and condensing steam turbine generator rotor of HEC is currently being manually extracted using a sliding plate method. The entire process requires the coordination of two cranes for lifting and moving, while the rotor of the generator still needs to be manually pulled and hoisted using a chain block towards the excitation end. The fixed points on both sides of the site and the rotor excitation end are secured using chain blocks, and multiple manual chain block operators follow instructions from the on-site commander to perform the extraction. This manual operation is inefficient and poses difficulties for the commanding personnel, especially during critical stages of the rotor extraction where excessive pulling or crane movement can cause significant vitions and potential damage to the equipment by collision between the rotor and stator components.This paper analyzes the issues present in the current traditional rotor extraction process of steam turbine generators and proposes the design of an automated rotor traction device. This device effectively addresses the aforementioned practical problems by reducing the need for crane lifting and movement, minimizing operational risks, reducing the number of required personnel, improving maintenance and inspection efficiency, shortening the overhaul period, and increasing the economic benefits of the power plant.
