Popis: Анализируются данные, полученные в результате поверки трехфазных счетчиков электрической энергии с помощью среды визуального программирования Orange. Для визуализации данных и их взаимосвязей построены диаграммы рассеивания, «ящик с усами» и гистограммы. Использованы модели машинного обучения, описывающие зависимости исходных параметров, выполнена оценка качества моделей
As you know, the metrological service of the power company constantly verifies electric energy meters. A series of measurements is carried out with one device in the mode of active and reactive power. As a result, the relative error of the working meter is determined, which is compared with the permissible error. Based on the results of the comparison, a conclusion is made about the suitability or unsuitability of this measuring instrument for use.I analyzed the data obtained as a result of checking three-phase electric energy meters using the Orange visual programming environment. To visualize the data and their relationships, scatter diagrams, a box with a mustache and histograms were constructed. Machine learning models describing the dependencies of the initial parameters were also used, and the quality of the models was evaluated. The tests were carried out for several months. A sample was used for the analysis, which included the results of 9854 measurements on 170 samples of nine types of meters from two manufacturers.
