Research And Implementation Of Dynamic Display Technology On Monitoring And Controlling Information In Distribution Network

With the construction of the smart grid, the information level and the scale of the distribution network are becoming huger. Along with the development of various information systems, monitoring systems, collectors, and other technologies, a large amount of data is generated in the distribution network. Dispatchers of the distribution network need a dynamic display system which can provide efficient information processing, accurate data processing and vivid data display. According to the requirements, the key technologies are analyzed and studied respectively in this paper.Firstly, the paper analyzes the business requirements of the distribution network monitoring information dynamic display system, and come to the conclusion that the system needs seven functions including data collection, system management, graphics management, data analysis, concurrent user session management, fault tolerance service and log service. Then according to the functional module of the system, the overall architecture of the system is designed and the three key issues-the establishment of the graphic data model, circuit analysis algorithm and the system model-are put forward. This paper makes a detailed study of these three problems. Based on the CIM model, the component and topological relationship of the electrical connection is modeled, and the graphic design of the components is completed by SVG technology. Then, according to the model, the software is completed, that is the dynamic display system of the distribution network monitoring information. Finally, on the basis of the traditional display technology, the switch status of the electrical wiring diagram are detected and the abnormal switch status are automatically corrected. In this paper, a scalable distribution network monitoring information dynamic display system is implemented, which can quickly draw electrical wiring diagrams and can also dynamically update them. This system can also quickly detect the abnormal status of the switches in the wiring diagram. Especially, the switch abnormal status detection algorithm expands the single function of the display technology, and also enhances the correctness and reliability of the information display, which is of great significance.
