Automatic Generation of Distribution System One-line Diagrams

Automatic generation of distribution system diagrams is an important aid for the distribution system planner and operator alike for easy visualization of the system. Since a Radial distribution system has a tree structure, what we need to develop is essentially a tree drawing algorithm. In addition,we aim to generate a distribution system graph that is aesthetically pleasing. We define a new set of aesthetics that are suitable for a graphical representation of the distribution system. The graph drawn keeping in mind the proposed aesthetics ensures that laterals are placed either perpendicular or parallel to one another .The node distances are suitably adjusted so that the branches do not cross each other.In addition the layout of the graph is such that smaller sub-graphs are always laid out on either side of the larger sub-graph.These factors enhance the appearance of the graph.
