Abstract
The invention discloses a feeder health degree calculation method and system. The feeder health degree calculation method comprises the following steps: S1, obtaining basic data for calculating the health degree of a feeder, wherein the basic data is obtained from a power grid system related to the feeder; S2, selecting a to-be-analyzed feeder line and querying a weight value of each influence factor influencing the health degree of the feeder line; S3, for each influence factor, calculating the influence level of the influence factor in feeder health degree calculation according to the basicdata and a preset rule; and S4, calculating the health degree of the feeder according to the weight value of each influence factor and the influence level of each influence factor in the calculation of the health degree of the feeder. According to the invention, the computer system is used for obtaining the feeder data from each power system, distributing the weight values for the influence factors influencing the health degree of the feeder according to the influence values, automatically calculating the influence levels corresponding to the influence factors according to the feeder data, calculating the health degree of the feeder according to the preset rules, and carrying out rapid and automatic analysis, so that the timeliness is strong and the accuracy is high.
Description
technical field [0001] The present invention relates to the field of power distribution systems, and more particularly, to a method and system for calculating feeder health degree. Background technique [0002] The feeder health degree is to analyze the health degree of the feeder under certain conditions. The lower the value of the health degree, the more ideal the operating state of the feeder is. Modern society has higher and higher requirements for the power supply reliability of the power grid. It is very important to find the weak links in the power grid in time and take corresponding pre-control measures, which is related to the safe and stable operation of the power grid. Among them, the traditional feeder health depends on manual analysis, which has poor timeliness, low efficiency, and insufficient accuracy. At present, there is no similar method in the field of grid system operation to realize computer automatic scanning analysis. Contents of the invention [...
