Application of visualization technology based on SVG in on-line relay settings verification system

As more and more electric power automation system integrated to dispatch automation platform, standardization of power graphics system and graphics sharing technology is one of the most important field of research of power automation system. The problems encountered in graphic modeling of on-line relay settings verification for protective relay are analyzed. A scheme which exports graphic files from protection relay setting coordination system, fault information system with the format of scalable vector graphics then the files are imported into the given value online checking system is presented. The goal seamless link between power automation systems is reached. Based on the requirements analysis of graphical interaction and data visualization in on-line relay settings verification for protective relay, by the way of realizing intercommunication between of.net and JavaScript, the graphics in on-line relay settings verification system can be dynamically refreshed. The proposed method has been successfully app
