Power distribution network immunity influence factor index weight calculation method and system

Abstract

The invention provides a power distribution network immunity influence factor index weight calculation method and system. The power distribution network immunity influence factor index weight calculation method comprises the steps of obtaining power distribution network immunity influence factor index values in a pre-constructed index system; calculating an index integral row vector of each layer in the pre-constructed index system by adopting an improved analytic hierarchy process based on the power distribution network immunity influence factor index value; determining a power distribution network immunity influence factor composite weight of each layer based on the index integral row vector of each layer; wherein the index system is constructed by taking the power distribution network immunity influence as a first-level index layer, taking the index which influences the power distribution network immunity as a second-level index layer, and taking the influence factor of the index which influences the power distribution network immunity in the second-level index layer as a third-level index layer. According to the method, the improved analytic hierarchy process is adopted to calculate the composite weight of the power distribution network immunity influence factors of each layer, so that the calculated index weight is more accurate.

Description

technical field [0001] The invention relates to the field of intelligent distribution networks, in particular to a method and system for calculating the weights of factors influencing immunity of distribution networks.
