Abstract

The invention discloses a power distribution network data edge calculation model which comprises the following steps: (1) collecting state data of distribution network equipment to obtain a data set; (2) determining a clustering number K value; (3) determining a clustering radius-Euclidean distance; and (4) updating the clustering center and iterative output. The invention also discloses a power distribution network data distribution network equipment defect elimination auxiliary system and a defect elimination method based on an edge calculation model. The device is embedded and installed on power distribution network equipment, so that the dramatic increase of information can be relieved, the pressure of background data processing can be relieved, the background data processing time can be shortened, and the data processing rate of a power distribution network system can be improved. Related information such as primary and secondary wiring diagrams of the power distribution network equipment is stored in the system, the loss rate of the information is reduced, the defect elimination efficiency and accuracy of operation and maintenance team personnel are improved, and the defect elimination time cannot be delayed due to different models of the power distribution network equipment and different wiring modes.

Description

technical field [0001] The invention belongs to the technical field of electric power defect elimination assistance, and in particular relates to a defect elimination auxiliary system for distribution network equipment based on edge computing, and also relates to a defect elimination method of the defect elimination auxiliary system. Background technique [0002] With the continuous development and progress of the society, the demand for electricity from industry, commerce and residents has risen sharply, and the construction of the power grid is also developing rapidly. higher and higher requirements. On the one hand, the sharp increase of information uploaded by distribution network equipment has caused information transmission delay, time and bandwidth to increase, seriously affecting the data processing rate of the distribution network system; , The low data processing rate of the distribution network system will lead to prolonged working hours and high psychological pr...
