Abstract

The invention relates to an evaluation method for distribution network reliability, comprising the following steps: (1) transferring evaluation of the distribution network reliability to analysis on the distribution network blackout power factors, and carrying out decoupling treatment on the distribution network blackout power factors; (2) using an analytic hierarchy process (AHP) to establish an evaluation system of distribution network reliability; (3) establishing a comprehensive quantitative model of the distribution network reliability; (4) formulating an evaluation standard of the distribution network reliability; and (5) specifying weight indicators of the distribution network reliability. In the method, the evaluation theory of the distribution network reliability is combined with an actual power grid, so that the evaluation of the distribution network reliability is transferred to the analysis on the distribution network blackout factors and the evaluation system, the evaluation model, the evaluation standards and the evaluation indicator weights of the distribution network reliability are established, thus enabling to reflect the existing reliability level of the distribution network from a plurality angles, thereby playing a huge role in works, such as related decisions, high-reliability power supply area distribution network plans and the like on evaluation of the distribution network reliability, formulation of high-reliability distribution network establishment principle and establishment direction, and the like.

Description

technical field

[0001] The invention belongs to the field of power distribution network, in particular to a distribution network reliability evaluation method. Background technique

[0002] During the operation of power system distribution network, high requirements are put forward for the reliability of distribution network. How to analyze and evaluate the reliability of distribution network has been concerned by various aspects. At present, the evaluation of distribution network reliability mainly includes reliability statistical analysis methods, power supply reliability information analysis, power grid construction analysis related to power supply reliability, analysis of power supply reliability improvement measures, etc. Some of these methods focus on theoretical research However, it is difficult to play a guiding role in practical applications. Some of them only analyze the actual accidents and do not consider the causes of accidents as a whole. Therefore, the existi...
