Abstract: A new model of
distribution system is presented,whereby the feeder switches are regarded as the vertexes
of a graph and the feeder lines are regarded as the arcs. Several data structures are
defined to describe the distribution system such as net-base matrix, arc matrix and load
matrix, etc. Based on the proposed data structure, the transforms of
base-to-shape,vertex-to-arc, and arc-to-vertex are discussed together with the process of
detection and isolation of fault sections,load balancing, optimum rest oration and
dispatching simulation.
