Metering equipment operation quality evaluation method based on CRITIC and ideal point method

Abstract

The invention discloses a metering equipment operation quality evaluation method based on a CRITIC and an ideal point method, and relates to the field of electric power. At present, the operation quality evaluation of metering equipment cannot give consideration to the simplicity and accuracy of calculation. According to the technical scheme, firstly, five evaluation indexes for measuring the quality of the electric energy metering equipment are defined based on operation monitoring big data of the electric energy metering equipment in an electric power information acquisition system, and thefive evaluation indexes comprise the load acquisition availability rate, the data acquisition integrity rate, the average fault-free working time, the operation abnormity alarm frequency and the operation fault rate index; then, objective weight of an electric energy metering equipment quality evaluation index is determined by adopting a CRITIC method based on entropy weight and a Spearman level correlation coefficient, and an electric energy metering equipment quality evaluation model is constructed based on an ideal point method; according to the technical scheme, the operation quality of the electric energy metering equipment can be quantitatively evaluated, the advantages and disadvantages of the electric energy metering equipment can be reasonably evaluated, and the simplicity of calculation and the accuracy of evaluation are considered.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a measurement equipment operation quality evaluation method based on CRITIC and the ideal point method. Background technique [0002] The power consumption information collection system plays an important technical support role in business applications such as power transaction settlement, power analysis, and demand-side management. Electric energy metering equipment such as energy meters and collection terminals are important components of the power consumption information collection system. It directly affects the data quality and application level of the power consumption information collection system, as well as the safe, stable and economical operation of the system, and even directly affects the reliability of power supply and the accuracy of power consumption metering by power users. The quality assessment of electric energy metering equipment is one of the important means to...
