Embodiment Construction

[0034] like figure 1 The urban power grid comprehensive evaluation system of the present invention based on AHP and Delphi method as shown in -2, wherein the power grid comprehensive evaluation system should at least include: basic data collection, establishment of hierarchical structure, calculation and scoring of individual indicators, comprehensive scoring and problem analysis and so on.

[0035] (1) Basic data collection

[0036] 1) Geographical wiring diagram of current medium voltage distribution network

[0037] The drawing is completed with the current road network map as the background, including the location of each substation, the main line, the direction of the large branch, the position of the subsection switch, the contact switch, and the name of the main line.

[0038] 2) One-line diagram of each line

[0039] It should include the connection relationship of each node of the line, the type and length of each segment of the wire, the location, capacity, and mo...

Abstract

The utility model discloses a present city power network comprehensive evaluation system based on analytical hierarchy process and Delphi method. The system classifies and layers the characters of the city power network and then forms an integrated system including a plurality of layers according to the relationships and the differences between the characters of the city power network. The endmost character of the system is first evaluated, and then calculation is performed one layer after another according to definite calculation methods, finally a comprehensive and integrated evaluation of the city power network is obtained. The higher the comprehensive score, the better the whole situation of the city power network; namely, the construction technology rationality, the operation safety, the power supply quality and the operation economy of the power network all reach to a high level.

Description

technical field [0001] The invention relates to an analysis method for the current power grid in urban power grid planning, which uses the analytic hierarchy process to divide the urban power grid according to the characteristics, establishes the hierarchical structure of various characteristics, and uses the Delphi method to synthesize the opinions of various experts to give the evaluation standards and the characteristics of each characteristic. its weight to get the final evaluation result. It belongs to the technical field of urban power grid planning. Background technique [0002] Before the widespread application of electronic computers, the staff of the livelihood section of the power sector or each station area used manual manual description of equipment installation sites, recording equipment operating conditions, and management of the distribution network. In this case, the workload of statistics and sorting out the basic data of the distribution network is alread...
