Embodiment Construction

[0094] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0095] Such as figure 1 As shown, a method for evaluating the operation status of an urban distribution network includes the following steps:

[0096] Step 1: Select the distribution network to be evaluated;

[0097] Step 2: Obtain the basic data of the distribution network from the grid system;

[0098] Step 3: Use basic data to calculate various performance indicators of the distribution network;

[0099] Step 4: Calculate the score of each performance index according to the performance index scoring formula;

[0100] Step 5: Multiply the scores of each performance index with the corresponding weight factors and then sum them up to obtain the evaluation score of the distribution network, and determine the operating status of the distribution network based on the evaluation score;

[0101] Divide the evaluation scores into 4 grades, namely "Excelle...

Abstract

Disclosed in the invention is a running state evaluation method of an urban distribution network. According to the method, with combination of actual investigation and expertise, single indexes capable of reflecting a running state of a distribution network comprehensively are selected by following the principles of objectivity, high accuracy, mutual independence, and high operability in a perspective of system engineering; superior indexes which the single indexes belong to are defined based on an analytic hierarchy process method, and an overall and complete index system is established and so on; a scoring formula of the single indexes is determined based on combination with the correlated industrial standard and the expertise by using a fuzzy membership function, and weight factors of all indexes are determined by using a pairwise comparison matrix method; and with running data collected by other systems of the distribution network automatically, scores of all indexes are calculated and then a running state evaluation score of the whole distribution network is provided.

Description

technical field [0001] The invention belongs to the field of distribution network operation analysis and relates to a method for evaluating the operation state of an urban distribution network. Background technique [0002] As a link in the power system that directly faces end users, the power distribution system is directly related to the reliability of power consumption and the quality of power supply for users. For a long time, the country has paid more attention to the construction of the transmission network and neglected the construction of the distribution network, resulting in power distribution. There are many weak links in the power grid, and most of the power outages are caused by the poor operation status of the distribution network. At the same time, the economic rationality of the operating state of the distribution network is also related to the economic benefits of the power sector. To effectively eliminate the weak links in the distribution network, we must ...
