Problems solved by technology

FMEA is exhaustive and can reliably solve reliability criteria (including load point, feeder and system reliability criteria). However, when the system structure is complex, on the one hand, due to the large number of components to be analyzed, the method will become very complicated. On the one hand, the load level of important power users is high, and the boundary conditions and factors that need to be considered when selecting a power supply mode are complex. The direct application of the distribution network power supply mode selection theory cannot reflect the characteristics of important users thems

Embodiment Construction

[0073] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0074] 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...

Abstract

The invention provides an important power user power supply reliability estimation method based on an analytic hierarchy process. The method comprises steps: according to an evaluation index, the analytic hierarchy process is used for building an evaluation structure for evaluating reliability of important power user power supply; candidate power supply modes are determined; an evaluation index in an evaluation rule in an index layer is calculated, and index scoring is carried out on the evaluation index; weight allocation is carried out on the evaluation index in the evaluation rule and the evaluation rule in the rule layer; and the evaluation rule is scored, and a score of the power supply mode is determined. The method of the invention can be applied to analysis on reliability evaluation on the power supply mode for the important power user in a distribution system and reliability evaluation on an important user distribution system.

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...
