A method for evaluating the rescue priority level of power line post-disaster based on AHP

In recent years, various natural disasters occurred frequently, such as earthquake, typhoon, etc. These disasters constitute a great threat to the safe and stable operation of the power grid, at the same time, it also puts forward higher requirements for the rescue work of the power line post-disaster. For this reason, this paper puts forward a method for evaluating the rescue priority level of power line post-disaster based on analytic hierarchy process (AHP). This method improves the traditional analytic hierarchy process (AHP), and based on this, by application of cask theory, constructing a hierarchical structure model for rescue priority evaluation, constructing the judgment matrix, calculation of the evaluation index weigh, consistency check, dimensionless of evaluation index, calculation of rescue priority value, determination of rescue priority and a series of work, complete the evaluation of rescue priority level of power line post-disaster. This method provided decision support for rescue of power line post-disaster, greatly improved the efficiency of post-disaster rescue work, minimize the loss of economy, it is of great significance to safe operation of power grids.
