Based on Distribution System Reliability evaluation state labeling section

The present invention relates to the field of power system state labeling, in particular to a distribution network based on the reliability evaluation state labeling section, wherein the method is based on binding segment and distribution network for the reliable failover assessment state labeling, enumeration failures of each section, for each segment of the fault, all segments of the state flag and its internal components, save the result to the tag structure of the vector data corresponding to the faulty zone; the said method comprising the steps of :( a) based on the reliability evaluation state flag preprocessing section; (ii) calculates the reliability index cycle. Since the present invention is less than the number of the distribution network segment feeder section, only the process at the first depth based searches search line segment, and then through all of the sections for each segment fault, to avoid the each line segment tedious process of failures must traverse all feeders segments, reflecting efficiency.
