Condition Evaluation System of Low Pressure Metering Box Based on AHP-Grey Fixed Weight Clustering

Abstract

The invention relates to a low-pressure metering box state evaluation system based on AHP- grey fixed weight clustering, composed of several acquisition terminals for acquiring evaluation index information of low-pressure metering box state; at least one evaluation end, configured to obtain an expert scoring value of the evaluation index according to the evaluation index information; a processingend which is used for realizing the information transmission between the obtaining end and the evaluating end, and obtaining the health status of the low-pressure measuring box to be evaluated by adopting the method of combining AHP and gray clustering based on the expert scoring value of the evaluating index; wherein the processing end obtains the end and evaluates the end respectively through the network. Compared with the prior art, the invention has the advantages of high reliability of the evaluation result, realizing automation process and the like.

Description

technical field [0001] The invention relates to the technical field of low-voltage metering box state detection, in particular to a low-voltage metering box state evaluation system based on AHP-gray fixed weight clustering. Background technique [0002] In recent years, with the continuous improvement of distribution network automation level and society's requirements for power supply reliability, low-voltage metering boxes, as an important part of electric energy metering, are the basis for ensuring electric energy trade settlement between power companies and customers. Accurate measurement and sound structure are correct. Measurement prerequisites and guarantees. If an abnormal event of the metering device occurs, it will seriously affect the company's high-quality service level, cause disputes with customers, cause complaints or news events, etc. Therefore, its own operating status has an extremely important impact on the quality of power metering work. [0003] The proj...

Problems solved by technology

The sample low-voltage metering box involves more than 20 manufacturers. The material of the box body includes metal, plastic and glass fiber reinforced plastics. The number of meters ranges from single meter to nine meters. Covering indoor and outdoor, the operating locations are not only near the Yangtze River Estuary and coastal areas, but also chemical and steel factory areas. From residential buildings, to commercial areas, and to industrial areas, it basically covers all power supply areas in Shanghai. It is found that the low-voltage metering box is in operation. There are still the following problems: (1) In order to facilitate the adjustment of structure and performance, the current low-voltage metering boxes mostly adopt modular design. Once problems occur in the process of assembly and wiring, it is easy to bring safety hazards; During the long-term operation and maintenance process, the keyholes, hinges, and lock noses of the low-voltage metering box door are broken, fallen off, deformed or damaged, which will not only easily cause economic disputes, but also affect the power grid and personal safety; (3) the low-voltage metering box often Installed at the entrance of corridors and shafts, preventing electricity theft and accidental electric shock of passing pedestrians has always been a difficult problem to ensure the safe and reliable operation of metering equipment
