Research and application of distribution line information model and automatic mapping display technology based on SVG

In view of the existing distribution line information storage is not unified, the formation of the diagram is not clear, the protection configuration chaos and so on. This paper presents a standard information model based on the electric quantity of distribution lines. Based on this model, an automatic mapping and display method of distribution lines is proposed. On this basis, a set of auxiliary decision-making software for hierarchical protection configuration of distribution lines is developed based on scalable vector graphics (SVG) software mapping technology. The automatic optimization of distribution line protection configuration is realized. The effectiveness and practicability of the technology are verified by the software operation, manual calculation and field application.
