Embodiment 1

[0043] Such as figure 2 As shown, the test is scored according to the standard, and several smart meters of the same batch or model are tested, and the test results are compared and scored. The scoring results replace the expert scoring system in the traditional QSPM matrix and become an improved QSPM matrix, which combines the evaluation system with the standard test results, increasing the objectivity and scientificity of the evaluation system.

[0044] In order to verify the validity of the method proposed in the present invention, actual experimental calculations were carried out. The experiment was carried out in a provincial metering center. A total of 10 smart meters of the same model, manufacturer or batch were randomly selected as samples, and the score was calculated using the improved QSPM matrix smart meter comprehensive evaluation method, and the scoring results were compared with the actual use of the metering center. verify.

[0045] A total of 10 experts inc...

Abstract

The invention discloses a method of intelligent electric meter modeling test comprehensive evaluation and analysis of an improved QSPM matrix. The method comprises the steps of 1, determining multiple modeling test accuracy influence factors of an intelligent electric meter according to modeling test requirements of GB / T 17215; 2, conducting multiple times of importance rating on the multiple influence factors of the intelligent electric meter according to practical using condition to obtain a weight coefficient; 3, introducing a grey theory and fuzzy mathematics to conduct deduction and calculation on a matrix, combining the weight coefficient to conduct calculation, and finally obtaining an intelligent electric meter evaluation score of the modeling sample. The method of intelligent electric meter modeling test comprehensive evaluation and analysis of the improved QSPM matrix has the advantages that the improved quantitative strategy plan matrix is adopted to classify the influence factors of the intelligent electric meter quantitatively, and the grey theory and fuzzy mathematics are introduced to conduct final comprehensive evaluation of performance indexes of the intelligent electric meter; a quantitative, diversified and comprehensive management evaluation basis is provided for a unit of measurement to conduct accuracy evaluation of the intelligent electric meter.

Description

technical field [0001] The invention relates to the technical field of comprehensive evaluation management of smart electric meters, in particular to an improved QSPM matrix smart electric meter type test comprehensive evaluation and analysis method. Background technique [0002] As a terminal measuring instrument for power products, smart meters play an extremely important role in power grid construction. GB / T17215 gives the requirements for the type test and performance parameters of smart meters, and clearly stipulates the range of accuracy changes of smart meters under the influence of environmental temperature, voltage, current, frequency, harmonics, radiation disturbance and conduction disturbance. . Manufacturers of smart meters need to strictly produce in accordance with standard requirements, and must pass the calibration inspection of authoritative quality supervision units. However, due to the large number of manufacturers and the uneven quality, there will stil...
