Abstract:

Abstract:Concerning such characteristics as the large tonnage,the high hoisting height and the fast amplitude of upstream and downstream water level,the Three Gorges Project ship lift is currently the largest ship lift in terms of its technical difficulty and scale in the world.This paper gives an overview of safety system and its application in the Three Gorges Project ship lift,followed by the analysis of system equipment selection,fault classification and control flow.It is concluded that the application of safety system ensures the stable operation of the Three Gorges Project ship lift and greatly improves the overall system reliability as well.

Key words: Keywords:Three Gorges Project ship lift, safety system, control flow, fault classification, equipment selection
