Abstract: Analysis was made to the application and its advantages and disadvantages of stator variable frequency speed control method in pumping station. Introduction was made to the feasibility of application for AC excitation motors with a large amount of application in wind power generation in pumping station. This paper studied the application prospect of inner feed-back speed control method which has been successfully applied in tap water supply plants in pumping station. During the building and rebuilding of large-size and mediumsize pumping stations, new type of speed control method was actively popularized, so as to reach investment saving, energy saving and lifting pumping station technology goals.
Key words: pumping station; variable frequency speed control; AC excitation motor; inner-feedback speed control
