Abstract: In the operation and maintenance phase of the pump and sluice project, it involves a large number of tasks of maintaining electromechanical equipment, for which the traditional way is that according to the scheduled maintenance plan in advance, the maintenance management personnel carry out maintenance and repair work of all kinds of equipment by inquiring the two-dimensional drawings, documents, and other piles of data of the equipment. However, it is time consuming and difficult to manage effectively. Against the drawbacks above, under the premise of considering the characteristics of maintenance management of electromechanical equipment in pump and sluice project, this paper fully analyzed the basic information of maintenance management activities, and point out the limitation of the traditional management method and its breakthrough direction.Then combined with BIM technology and IFC standard system, and established a new information model of maintenance management of electromechanical equipment in pump and sluice project. Finally, a maintenance management platform was designed for electromechanical equipment, which provides systematic support for the maintenance and management of electromechanical equipment of hydropower stations based on its 3D visualization function and comprehensive maintenance knowledge database.
