Electric energy meter manufacturer evaluation method based on multiple evaluation indexes

Abstract

The invention discloses an electric energy meter manufacturer evaluation method based on multiple evaluation indexes, which relates to an evaluation method. The invention comprises the following steps: acquiring the original data of the electric energy meter and determining an evaluation index; Calculating each index value of the electric energy meter, construct the index matrix, forming the decision matrix; Calculating the information entropy and Spearman grade correlation coefficient of each index value of watt-hour meter, determine the objective weight of the quality evaluation index according to CRITIC method, processing the decision matrix and obtain the watt-hour meter supplier evaluation matrix; Calculating the positive ideal solution and negative ideal solution of the watt-hour meter supplier, and calculating the Euclidean distance from each watt-hour meter supplier to the positive ideal point vector and the negative ideal point vector. Calculating the relative approximation degree between each watt-hour meter supplier and the ideal solution, and determine the quality level of each watt-hour meter supplier from high to low. The technical scheme provides an objective and scientific basis for the electric energy meter quality evaluation and supervision of the power grid company.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an evaluation method for electric energy meter manufacturers based on multiple evaluation indexes. Background technique [0002] The electricity consumption information collection system plays an important technical support role in business applications such as power transaction settlement, power analysis, and demand side management. As an important part of the electricity consumption information collection system, the energy meter directly affects the quality of the user's electricity consumption information. The data quality and application level, the accuracy of electricity metering by power users, and the safe, stable and economical operation of the system are even directly related to the reliability of power supply. The quality assessment of electric energy meters is one of the important means to ensure and improve the quality of electric energy meters, and it is a key link in t...
