Abstract

The invention discloses an intelligent distribution-network fault location method based on an angle analysis weighted algorithm, and relates to the technical field of intelligent location methods. Themethod comprises the following steps that 1) maintenance time lengths required by different types of distribution network faults are analyzed and classified according to historical data, and the different types of faults are assigned with weights respectively; 2) an angle analysis method is used to locate the external boundary range of a transformer area of the distribution network fault; 3) a monitor is used to monitor the distribution network fault in real time; 4) a monitoring console weighs the analyzed fault data according to the weights in the step 1); and 5) tasks are distributed to distribution network tour inspectors according to the total fault value of the transformer area in the step 4). All faults of the transformer area are counted in a weighted manner, and the total fault value of the transformer station is generated, so that the total maintenance time length required by the faults in the transformer areas can be obtained, and the tasks are distributed to the tour inspectors according to the weights of different faults.

Description

technical field [0001] The invention belongs to the technical field of intelligent positioning methods, in particular to an intelligent positioning method for distribution network faults based on an angle analysis weighting algorithm. Background technique [0002] In the power system, the station area refers to the power supply range or area of ​​the transformer. It is a term for the operation and management of electric power economy. The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. It is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some auxiliary facilities, etc., and plays an important role in distributing electric energy in the power network. [0003] At present, after the...
