Embodiment

[0018] A fault area positioning system based on transmission line transient wave recording technology, including an acquisition module, a control module and a power distribution master station, and the acquisition module, the control module and the power distribution master station are connected through wireless communication;

[0019] The acquisition module is installed on the overhead power distribution line. Under the low-power operation state, the real-time wave recording method is used to store the transient waveform of the transmission line in a large-capacity cycle in the memory chip, and to judge when a fault occurs, and The collected and captured single-phase ground fault and short-circuit fault information is uploaded to the control module by means of wave recording data window interception; the control module is installed on the transmission tower to receive and process the collected information uploaded by the collection module , and upload the collected information...

Abstract

The invention discloses a fault area positioning system based on a power transmission line transient wave recording technology. An acquisition module, a control module and a power distribution main station are connected in a wireless communication mode; the acquisition module is installed on an overhead distribution line and uploads acquired and captured single-phase earth fault and short-circuitfault information to the control module. The control module is installed on a power transmission tower, receives and processes the collected information, and uploads the collected information to the power distribution main station. The power distribution main station carries out fault detection and positioning and transmits fault information to the operation and maintenance personnel mobile terminal. The current state of the line is recorded, the fault state information is uploaded and processed in time, a user can be quickly and accurately informed of the fault type and the generation reason,and the operation reliability of a power grid is improved.

Description

technical field [0001] The invention relates to the technical field of transmission lines, in particular to a fault area positioning system based on transmission line transient wave recording technology. Background technique [0002] DC transmission has unique advantages in long-distance and large-capacity transmission. In recent years, HV / UHV DC transmission has developed rapidly in China. Thousands of kilometers of direct current transmission lines have to cross complex terrains such as forests, mountains and rivers, which will undoubtedly bring various difficulties to line inspection work after line failures. Therefore, quickly and accurately locating the fault area of ​​the transmission line is of great significance for the rapid elimination of the line fault, the restoration of power supply, and the safety and stability of the AC and DC system. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention p...
