Power transmission line fault and abnormal discharge monitoring system and method

Abstract

The invention discloses a power transmission line fault and abnormal discharge monitoring system. The system comprises a monitoring terminal which is used for collecting waveforms, dividing the collected waveforms into a power frequency waveform, a discharge current waveform and a fault traveling wave current waveform, forming a machine code, and transmitting the machine code back to a data center in a wireless mode; the data center which is used for receiving the waveform information returned by the monitoring terminal, restoring original waveform data through an analysis means, storing the original waveform data in a corresponding table structure, processing and analyzing the original waveform data, and storing an analysis result; and a front-end display system which is used for reading data contents in the data center table structure and visually displaying the data contents. The technical problems that in the prior art, an infrared imager, a laser range finder and the like are adopted for troubleshooting on site, video visualization monitoring has the defects of small monitoring area, large flow consumption and high cost, and manual inspection is low in instantaneity, large in workload and the like are solved.

Description

technical field [0001] The invention belongs to the transmission line monitoring technology, in particular to a transmission line fault and abnormal discharge monitoring system and method. Background technique [0002] The environment of transmission lines is complex, and various external factors often lead to line tripping accidents. Such external factors that cause line tripping include instantaneous tripping faults caused by lightning strikes, external breaks, etc., as well as tree barriers, For gradual faults caused by insulator pollution, metal fitting floating discharge, etc., there is an essential difference in the time it takes for the two to develop to fault tripping, such as tree barriers, insulator contamination, fittings floating discharge, etc. There is a long pre-discharge process, which usually takes several days to more than ten days depending on the cause of the trip accident. [0003] For the monitoring of instantaneous faults of transmission lines, the di...
