Research on remote visual operation and maintenance of substation GIS equipment based on digital modeling

At present, the loading speed of model scene is slow in the visual operation and maintenance process of substation GIS equipment, which leads to poor visual operation and maintenance effect. In order to solve this problem, a remote visual operation and maintenance method of substation GIS equipment based on digital modeling is proposed. According to IEC61850 standard, the digital modeling of substation AC charging pile, DC charger and other main equipment is completed. The multi tree hybrid structure is generated by using the model data organization and dynamic operation and maintenance method, and the ground object model of substation is constructed to improve the loading speed of the model. The remote visual operation and maintenance of substation GIS equipment is realized by using the map model mapping technology. The experimental results show that the method can effectively improve the loading speed of the model scene, the average loading frame rate is 42 frame/s, and has good visual operation and maintenance effect and strong practical application.
