Abstract

The present invention provides a method for evaluating the reliability of power supply of important power users based on AHP. The method includes: establishing an evaluation structure for evaluating the reliability of power supply of important power users by using AHP according to evaluation indicators; determining candidate power supply modes; calculating The evaluation indicators of the evaluation criteria in the index layer and perform index scoring on the evaluation indicators; carry out weight distribution on the evaluation indicators under the evaluation criteria and the evaluation criteria of the criterion layer; score the evaluation criteria to determine the classification of the power supply mode value. This method is suitable for analyzing the reliability evaluation of power supply mode of important power users in power distribution system and the reliability evaluation of power distribution system including important users.

Description

technical field

[0001] The invention relates to a method in the field of power distribution system reliability evaluation, in particular to a method for evaluating power supply reliability of important power users based on analytic hierarchy process. Background technique

[0002] Power system reliability assessment began in the late 1960s. Initially, it mainly focused on the power generation and transmission system, because the configuration of power generation and transmission equipment is relatively concentrated, the one-time investment is large, and the construction period is long. Equipment failure or outage will bring serious and extensive negative effects to society and the environment. However, in fact, the power distribution system, which is the terminal link of the power system to the user, has the greatest impact on the user's power supply performance, because related surveys show that about 80% of the user's power outages are caused by the failure of the power dis...

Embodiment Construction

[0072] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0073] The present invention provides an important power user power supply reliability evaluation method based on AHP, such as figure 1 as shown, figure 1 For the flow chart of power supply reliability assessment for important power users, according to the analytic hierarchy process, from the four aspects of reliability, adaptability, economy and power quality, a comprehensive comprehensive analysis system consisting of four levels: plan level, index level, criterion level and target level is constructed. For the evaluation system architecture, the weight distribution of each index is determined in a bottom-up manner by using the 9-digit scale method and expert experience. On this basis, the detailed scoring results of 14 typical power supply modes are given in order to provide the necessary theoretical basis for engineering appli...
