Anti-colony-algorithm-based distribution network fault positioning method

Abstract

The invention discloses an anti-colony-algorithm-based distribution network fault positioning method. The method comprises: an anti colony algorithm evaluation function is constructed; and fault positioning is carried out by using an anti colony algorithm. When the anti colony algorithm is used for carrying out fault positioning, the evaluation function serves as a basis of an evaluation solution performance; and the good performance expresses the selected path is short. When equipment with the fault in the distribution network is diagnosed, a hypothesis is found and all uploaded RTU or FTU information can be explained well; and thus deviation of the corresponding FTU or RTU information and actual uploaded information is minimized by finding the hypothesis, thereby realizing fault positioning of the distribution network.

Description

technical field [0001] The invention relates to the field of distribution network fault location, in particular to a distribution network fault location method based on an ant colony algorithm. Background technique [0002] The distribution network fault location system is a real-time online processing system. Most of the fault information comes from the outdoor FTU communication device. The working environment is harsh and the temperature difference range is large, and most of them are installed on the power line column or in the distribution cabinet. It must withstand high voltage, current, lightning and other interference factors; the distribution network has many and scattered communication points, it is difficult to use the same communication method to solve the problem, in practical applications, generally adopt mixed communication methods, coupled with loose switch nodes , FTU's own misjudgment and other factors, the possibility of interference or loss of distribution...

[0002] The distribution network fault location system is a real-time online processing system. Most of the fault information comes from the outdoor FTU communication device. The working environment is harsh and the temperature difference range is large, and most of them are installed on the power line column or in the distribution cabinet. It must withstand high voltage, current, lightning and other interference factors; the distribution network has many and scattered communication points, it is difficult to use the same communication method to solve the problem, in practical applications, generally adopt mixed communication methods, coupled with loose switch nodes , FTU's own misjudgment and other factors, the possibility of interference or loss of distribution network fault information must exist

For the distribution network fault location matrix algorithm, when the uploaded information of each FTU is wrong, misjudgment often occurs, resulting in the expansion of the scope of the accident, the extension of the power outage, and the direct reduction of the reliability of the power supply.
