Intelligent electric energy meter reliability comprehensive evaluation model in typical environment

Abstract

The invention belongs to the technical field of intelligent electric energy meter reliability comprehensive evaluation, and provides an intelligent electric energy meter reliability comprehensive evaluation model in a typical environment, which comprises the following steps: (1) constructing an intelligent electric energy meter reliability comprehensive evaluation index system in the typical environment; (2) calculating the weight of each index in the intelligent electric energy meter reliability comprehensive evaluation index system in a typical environment by adopting an analytic hierarchy process; and (3) carrying out comprehensive evaluation analysis by adopting a gray weighted correlation method. According to the method, an analytic hierarchy process is adopted to establish an intelligent electric energy meter reliability comprehensive evaluation index system in a typical environment and calculate the index weight of the index system, and a gray weighted correlation analysis method is utilized to comprehensively evaluate the reliability of intelligent electric energy meters of manufacturers in the typical environment. Experiments show that the evaluation model is used for comprehensive evaluation of the reliability of the intelligent electric energy meter in a typical environment, and the evaluation result is objective and accurate.

Description

technical field [0001] The invention belongs to the technical field of comprehensive evaluation of the reliability of smart electric energy meters, and specifically proposes a comprehensive evaluation model for the reliability of intelligent electric energy meters in a typical environment. Background technique [0002] In the actual environment, the environmental conditions faced by the smart energy meter are changeable, and the product problems are easily exposed in the long-term operation under the conditions of high cold, high altitude, high humidity, high salt spray, and high dry heat. Carry out the type test (full performance) of the electric energy meter in accordance with the domestic technical standards, and it is difficult to find potential quality defects in a typical environment during the test process, because of the large number of factors involved in the fault induction process. Therefore, it is necessary to establish a set of reliability evaluation system of s...

AI Technical Summary

Problems solved by technology

Because the single AHP is too subjective, there are deficiencies and defects in evaluating the reliability of smart energy meters in typical environments. The evaluation results are relatively one-sided, and it is impossible to fully evaluate the reliability of smart energy meters in typical environments.
