The intelligent control system of substations faces several challenges, such as the long information collection time and low control efficiency. In order to solve these problems, this paper designs an intelligent management and control system of substation based on threedimensional (3D) model. Users can flexibly access the relevant information of substations by using 3D model built in 3D Max. On the basis of the 3D model, multiple tasks, including semantic Schema information design, implicit geometric design, and so on, can be achieved to accomplish the intelligent management and control system of substations according to CityGML standard. The experimental results show that the information acquisition time of the proposed system is significantly reduced, and management and control efficiency and quality are improved. Hence the proposed system can be further applied in practice.
