Abstract

The invention discloses a troubleshooting method and device of a power transmission line. The troubleshooting method comprises the following steps: acquiring real-time data of a plurality of pieces of power distribution equipment by a control power distribution terminal; acquiring real-time data from the power distribution terminal and saving the real-time data as historical data; screening out fault data from the historical data according to a predetermined parameter; recording the fault data. The real-time data collected and acquired from the power distribution equipment is stored to form the historical data, the fault data is screened out from the historical data and recorded, and automatic troubleshooting in the power transmission line is realized, so that the troubleshooting efficiency of a fault in the power transmission line is improved, and further the fault in the power transmission line is timely and effectively maintained.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and device for troubleshooting a power transmission line. Background technique [0002] Hundreds of power distribution equipment are installed in the existing transmission line, and these power distribution equipment can have different functions (on-off, power transformation, etc.) in the transmission line, so as to support the operation of the entire transmission line. Therefore, the failure of one or some power distribution equipment in the transmission line will affect the entire transmission line, resulting in the failure of normal operation in the transmission line. When the power distribution equipment fails, it is necessary to manually check the faults of these power distribution equipment one by one, and judge the cause of the failure, and then repair the power distribution equipment according to different failure reasons. However, sometimes it cannot be repaired in ...
