Rapid power restoration channel selection method and system for power transmission line fault

The invention provides a power transmission line fault rapid power restoration channel selection method and system, and the method comprises the steps: screening an emergency standby line of each power transmission line, building a fault rapid power restoration channel database of the power transmission lines according to a corresponding mapping relation, and finally calculating the score of each power restoration channel in the database according to a preset rule. Therefore, when the power transmission line fails, a good power restoration channel can be selected under the condition that the length of a T-connection wire of the line and a wire crossing object are considered, and the situation that the power restoration channel is determined in a manual on-site investigation and analysis discussion mode in a traditional method is avoided. The time efficiency of acquiring part data of the line is too low, and the first-aid repair time is too long. 本发明提供了一种输电线路故障快速复电通道选取方法及系统，通过筛选出每条输电线路的应急备用线路并根据对应的映射关系建立输电线路的故
