Distribution feeder one-line diagram generation: a visibility representation

摘要

An algorithm to automatically generate an aesthetically 'pleasing' and 'readable' one-line diagram of a radial distribution feeder is presented. Readability is sought to be achieved by using the visibility representation where buses and transmission lines are drawn as axis-parallel horizontal and vertical lines, respectively. In addition to this choice, a set of layout specifications for enhancing the readability of the distribution system has been proposed. It is assumed here that only the edge-list of the network is available and geographical information regarding locations of the nodes is unavailable. Using this limited input, the proposed algorithm determines the lengths and positions of lines that represent the buses and transmission lines of the network such that the proposed layout specifications are satisfied. Results of application of the algorithm on practical feeders are provided to illustrate its effectiveness.
