Problems solved by technology

[0004] The present invention aims at the problems of subjective uncertainty and objective limitations of existing distribution network evaluation methods, and proposes a distribution network evaluation method based on a combined evaluation method, and applies the combined evaluation method to distribution network evaluation. A set of multi-attribute and multi-objective distribution network evaluation system is established. The system evaluates the advantages and disadvantages of multi-regional distribution network according to the size of the combined evaluation value. The distribution network evalu...

Embodiment Construction

[0024] The steps of the distribution network evaluation method based on the combined evaluation method are as follows:

[0025] (1) Collect distribution network data, conduct statistical analysis, and divide the entire evaluation area into several small areas according to the nature and jurisdiction of the distribution network;

[0026] In the actual distribution network evaluation process, if the distribution network in a large area is evaluated as a whole, the weak area of ​​a certain index may be ignored, which will affect the conclusion of the distribution network evaluation. Therefore, the evaluation area can be divided into several small areas according to the nature and jurisdiction of the distribution network, and the current status of each sub-grid can be comprehensively evaluated to find out the weak links of the distribution network in the entire evaluation area.

[0027] (2) Analyze the various indicators of the evaluation project, and establish the index system st...

Abstract

The present invention relates to a distribution network evaluation method based on a combined evaluation method. The combined evaluation method is applied in distribution network evaluation, the prior comprehensive evaluation methods are applied comprehensively, and then the results of various kinds of evaluation methods with deviation are combined, so the distribution network evaluation method considers subjective and objective factors and has the advantages of various kinds of evaluation methods and has considerable reference function for concrete distribution network valuation at field, and the distribution network evaluation method can become the reliable and practical evaluation method for the distribution network planning personnel to evaluate and can greatly improve the standard of the prior distribution network planning comprehensive decision work. At the same time, the distribution network evaluation system can solve a series of practical problems in the distribution network evaluation very well, can direct and arrange scientific and reasonable distribution network constructing and rebuilding projects in practical evaluation and planning work and ensures the reliable and economical operation of the distribution network, thereby bringing great economic benefit.

Description

technical field [0001] The invention relates to a method for evaluating urban power grids, in particular to a method for evaluating combinations of urban power distribution grids. Background technique [0002] The distribution network evaluation is aimed at the distribution network in different stages of history, current situation, renovation and planning, combined with the management, operation and construction level of the distribution network, as well as the national economic development and municipal planning of the area where the distribution network is located, using modern system analysis Theory, formulate corresponding distribution network evaluation methods, evaluation standards and operating specifications, and form a unified and standard evaluation system and specifications. On this basis, carry out systematic and scientific analysis and evaluation of distribution network at different stages, and the comprehensive evaluation results obtained can provide detailed a...
