Power line discharge detection system for unmanned aerial vehicle line patrol and discharge positioning method

Abstract

The invention relates to a power line discharge detection system for unmanned aerial vehicle line patrol. The system comprises an unmanned aerial vehicle airborne discharge detection system and a computer operation display system. The unmanned aerial vehicle airborne detection system is used for rapid discharge detection of a power transmission line and local recording of data; the computer operation display system performs reading, analysis operation, data storage and visual display on the recorded data. The power line discharge detection method comprises the following steps that: a photomultiplier in an ultraviolet detection module performs swing detection; when the power transmission line discharges, multiple groups of signals can be detected in one swing period; and when the detectionsignal intensity is maximum in one swing period, the current swing angle of a turntable, the detection position obtained by a position information acquisition module and the voltage of the detection signal are recorded in a data recording module. The power line discharge positioning method comprises the following steps: importing data in the data recording module into the computer operation display system for positioning operation, and outputting successfully located discharge point position information. The system and methods have the characteristics of high detection speed, low omission ratio, accurate positioning and high inspection efficiency.

Description

technical field [0001] The invention belongs to the technical field of transmission line discharge detection, and in particular relates to a power line discharge detection system and a discharge positioning method for unmanned aerial vehicle line inspection. Background technique [0002] In the current society, electric energy has been popularized in all walks of life and has become the main energy source of human society. my country's power supply and demand presents an obvious imbalance between the east and the west. The State Grid solves the problem of power balance by extensively erecting high-voltage lines and other transmission facilities. Power transmission facilities are affected by various factors such as the environment, and discharge phenomena will occur. On the one hand, the discharge phenomenon indicates that there is a fault in the transmission facility, and on the other hand, it will aggravate the deterioration of the transmission facility.
