A standards-based approach for Auto-drawing single line diagram of multivendor smart distribution systems

This paper presents a technique for the auto-drawing of single line diagram (SLD) of multivendor distribution systems. SLDs are used in electric power system visualization, which is very important for the control and monitoring of distribution systems for fault location, identification, separation, and service restoration. The task of auto-drawing an SLD for distribution systems has been made complicated due to the introduction of distributed generations and multivendor distribution systems. This paper proposes an algorithm for auto-drawing SLD, based on a ternary tree and collision avoidance algorithm. In addition, a standards-based approach is suggested for incorporating different distribution system planned and run by different vendors. Initially, client converts the distribution system diagram to a standard model, which is then sent to the server. The server draws the SLD by using the auto-SLD drawing algorithm and sends it back to the client, which can be verified by the client.
