Problems solved by technology

[0004] However, the existing technology lacks a systematic and scientific evaluation of the distribution network, lacks a clear understanding of the location and severity of existing and upcoming problems in the distribution network, and cannot provide a good basis for the construction and transformation of the distribution network. According to the basis, there are still many problems in the transformed distribution network, which cannot meet the requirements of the majority of users.

Embodiment 1

[0063] Embodiment 1 of the present invention provides a distribution network evaluation method, the flow of which is as follows figure 1 shown, including the following steps:

[0064] Step S11: Starting from the index of the lowest level in the hierarchical index system of the distribution network, the index of the current level is used as the evaluation index in turn, and the index of the previous adjacent level of the current level is used as the evaluation object, and determined according to the index value of each evaluation index Scores for each evaluation object.

[0065] The highest-level indicator in the above-mentioned indicator system is the comprehensive performance of the distribution network, and the indicator system contains at least two levels of indicators, that is, there is only one indicator at the highest level in the indicator system. If there are multiple top-level indicators in the obtained index system, a top-level indicator can be constructed based on ...

Embodiment 2

[0089] Embodiment 2 of the present invention provides a specific application implementation of a distribution network evaluation method.

[0090] The pre-constructed distribution network indicator evaluation system can include four levels of indicators. The first-level indicators are the comprehensive performance of the distribution network, and the second-level indicators include power supply quality, grid structure, equipment level, power supply capacity, intelligence level, and grid efficiency. and comprehensive benefits. The next-level indicators of power supply quality include electrical reliability and voltage quality; the next-level indicators of grid structure include 110 (66) kV grid structure, 35kV grid structure and 10kV grid structure; the next-level indicators of equipment level include 110 (66) kV equipment standardization level, 35kV equipment standardization level, 110 (66) kV equipment age, 35kV equipment age, 10kV equipment standardization level, 10kV equipme...

Abstract

The invention discloses a power distribution network evaluation method and device. The method comprises the following steps: forming a substrate; starting from the index of the lowest level in the level index system of the power distribution network, sequentially taking the index of the current level as an evaluation index, taking the index of the previous adjacent level of the current level as anevaluation object, determining the score of each evaluation object according to the index value of each evaluation index, and taking the index of the highest level in the index system as the comprehensive performance of the power distribution network; and after the score of the highest level index is determined, taking the score of the highest level index as the score of the comprehensive performance of the power distribution network. According to the scheme, comprehensive evaluation can be carried out on the power distribution network containing multiple levels of indexes, analysis and evaluation can be carried out by integrating the mutual relation between different indexes of different levels and the same level, the evaluation result has higher rationality, accuracy and practicability,and supervision, management and scheduling of the power distribution network can be better guided.

Description

technical field [0001] The invention relates to the technical field of data analysis and evaluation, in particular to a distribution network evaluation method and device. Background technique [0002] 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 step by step according to voltage. Features. [0003] In recent years, with the rapid development of urban construction and the continuous improvement of people's living standards, the power load has increased rapidly, and higher requirements have been placed on the power supply capacity of the distribution network. Therefore, the comprehensive evaluation results of distribution network are of great significance to the operation and supervision of distribution network. [0004] However, the existing technology lacks a systematic and scientific evaluation o...
