Power transmission line patrolling strategy method based on lightning fault insulation recovery characteristic

The invention relates to a power transmission line patrolling strategy method based on a lightning fault insulation recovery characteristic. The flashover damage situation and the insulation characteristic recovery situation of an insulator are analyzed according to monitoring information generated at a fault moment, and finally a line patrolling strategy is provided. The method mainly comprises the following steps: firstly, acquiring the monitoring information at the fault moment; secondly, analyzing the characteristic according to the acquired monitoring information, and determining a fault position and the type of the fault; then determining the insulation damage degree and the insulation recovery performance of each fault; finally providing the line patrolling strategy according to the damage degree and the insulation recovery performance of the insulator. According to the power transmission line patrolling strategy method, the corresponding line patrolling strategy is provided based on the lightning fault insulation recovery characteristic at first, so that the power failure time is shortened to the maximum extent, and the safe operation of a power grid is guaranteed; meanwhile, the safety of a patroller is guaranteed, and the line patrolling efficiency is improved. The implementation process of the method is clear, and the method is put into the actual application of engineering; a good economical effect and social benefits are achieved.
