Abstract：According to unsatisfactory actuality of adjustable-speed drive system in mine hoists, a new speed adjusting scheme using AC double-fed motor system with duel PWM converter was put forward to replace the traditional scheme. This adjustable-speed drive system' s structure graph was given, then the strategy of vector control oriented by stator field was adopted and the control system' s model was designed. It can realize high technical standards such as none speed static difference, good following performance and unity power factor at the stator side under weight load. Taken hoist of 660 V grade as an example, all sorts of this system' s working situation during one lifting cycle was simulated in detail by Matlab. The simulation results prove that this scheme is applicable.
