Embodiment 1

[0042] A method for analyzing the distribution network operation status of a power grid, such as figure 1 shown, including the following steps:

[0043] (1) Obtain operating parameters from the distribution network management system. Parameters and parameter systems are the basis for comprehensive evaluation. Whether the parameter selection calculation is scientific and whether the parameter system setting is reasonable is directly related to the quality of project evaluation; safety, reliability and economy are The basic requirements for grid power supply; at the same time, there should be a margin for future grid development, so the operating parameters include:

[0044]The eigenvalue of the rationality of the current situation of the power grid. The essence of the eigenvalue of the rationality of the current situation of the power grid is the reflection, evaluation and specification of the value and significance of technical practice activities based on certain standards an...

Embodiment 2

[0060] On the basis of the description in Example 1, according to the 1-9 reciprocity scaling theory, the parameters of the same layer are compared in pairs to obtain a quantified judgment matrix.

[0061] Assuming that there are n parameters involved in the comparison, each parameter is compared with other parameters for a total of n-1 pairwise comparisons, and the comparison result between the i-th parameter and the j-th parameter is recorded as a ij , plus the result of comparison with itself a ii , can form an n×n square matrix, called the judgment matrix.

[0062] In the process of forming the judgment matrix above, the 1-9 reciprocity scale theory can be used for quantification, as shown in the table below. For example, there are three parameters to be compared, which are parameter 1, parameter 2 and parameter 3 respectively. According to the expert system analysis, the superiority of parameter 2 relative to parameter 1 is "strong", and according to the 1-9 scale table...

Abstract

The invention relates to a distribution network operating state analysis method for a grid. The method comprises the steps of obtaining operating parameters from a distribution network management system and establishing a corresponding layer structure according to characteristic values; according to a 1-9 reciprocity scale, making a pairwise comparison to the parameters on the same layer to obtain a quantified judgment matrix and judging the consistency of the judgment matrix by adopting a random CR (Consistency Ratio); after the matrix consistency is checked, solving a weight vector of the matrix according to 1-9 scale reciprocal judgment matrix; on the basis that the weights of the parameters of all bottom layers are obtained, performing upward calculation layer by layer to obtain the comprehensive operating state of the entire grid. The distribution network operating state analysis method for the grid has the advantages that the true data of the bottom layer can be directly extracted, the comprehensive baseline assessment of high-voltage and medium-voltage distribution networks can be quickly finished through scientific assessment system to obtain the macro parameters and main characteristics of the distribution networks, the problems in the distribution networks are automatically found, the severity and the specific positions of the problems are quantitatively described, the enterprise leads are helped to adjust the strategy in time and the quick coping capacity of enterprises is improved.

Description

technical field [0001] The invention relates to a distribution network operation state analysis method of a power grid, and relates to the field of distribution networks. Background technique [0002] The scale of the power grid is developing rapidly, and grassroots technical personnel have more and more basic data of the power grid, but senior leaders and their think tanks (development planning, planning, planning, biotechnology, etc.) cannot obtain processed and refined information for decision-making , this information gap can be resolved through the implementation of the evaluation system. [0003] The distribution network, also called the distribution network, refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or to various users according to the voltage host. The distribution network is composed of overhead lines, cables, towers, distribution...
