Non-outage operation detection method for power distribution network

Abstract

The invention discloses a non-outage operation detection method for a power distribution network, belonging to the technical field of power distribution. The non-outage operation detection method forthe power distribution network comprises steps as follows: arranging a temperature detection module, an electric field intensity detection module, a humidity detection module and a particulate detection module in each power distribution network operation detection sub-area; setting a temperature collection interval time value, an electric field intensity collection interval time value, a humiditycollection interval time value and a particulate collection interval time value in each power distribution network operation detection sub-area; setting a temperature interval threshold value, an electric field intensity interval threshold value, a humidity interval threshold value and a particulate interval threshold value in each power distribution network operation detection sub-area; and judging whether a power distribution circuits in the corresponding power distribution network operation detection sub-area is in fault. Through detection and analysis on the temperature, the electric field intensity, the humidity and the particulate concentration in the power distribution network, the method can determine the fault condition of the power distribution network without outage, has characteristics of high detection efficiency and high accuracy and is suitable for generalization and application.

Description

technical field [0001] The invention belongs to the technical field of power distribution, and in particular relates to a non-stop power-off inspection method for a power distribution network. Background technique [0002] With the advancement of science and technology and the rapid development of the economy, the society's demand for electricity has increased rapidly. However, with the continuous development of the distribution network cable process, the distribution network line structure is becoming more and more complex, and there are many branch lines. The requirements for the stability and reliability of power grids are getting higher and higher, and at the same time, users' requirements for power quality and services are also constantly improving. [0003] At present, manual inspection is mostly used for the maintenance of distribution lines, which requires a large number of line inspection and inspection personnel, and the current cable laying locations are diverse, ...

AI Technical Summary

Problems solved by technology

[0003] At present, manual inspection is mostly used for the maintenance of distribution lines, which requires a large number of line inspection and inspection personnel, and the current cable laying locations are diverse, and it is difficult to directly inspect them, and for the distribution network in operation The road, often adopts the mode of troubleshooting, only when the equipment is abnormal, the corresponding part is maintained and repaired

When a fault occurs, the repair time is long, which increases the power outage time, and the network structure of the distribution network makes the upper distribution point fail and the power outage will cause the overall paralysis of the lower-level electrical equipment, which reduces the user experience.

Therefore, in the prior art, in the process of distribution network operation inspection, not only the operation inspection time is long, the efficiency is low, the power outage time is long, and the distribution network operation inspection process is not timely and effective.
