The article discusses the application of modern business analytics tools to the analysis of operating modes of an alternating current power supply system, using the example of an electrified section of an AC railway with phase-by-phase measurement of instantaneous voltage and current values obtained from solving a system of differential equations. The analysis of the power supply system’s operating modes is justified by selecting analytical platforms such as Power BI, which has deep integration with Microsoft products, Tableau, known for its powerful data visualization capabilities, and Qlik, which employs an associative data model, allowing users to interact with data without the need to predict analysis methods. The AC railway power supply system under consideration includes traction substations and non-traction loads powered by the "two-wire-rail" (TWR) lines, as well as the external power supply system from which traction substations receive electricity. Based on the obtained instantaneous current values, Matlab՚s computer algebra tools were used to calculate the voltages at the nodes of the power supply system. Power components and integral indicators were calculated in the QlikView environment, which is used for processing a large volume of numerical data and visualizing it. The interactivity of switching between visualizations and the associative data model in QlikView allowed time savings when analyzing large amounts of information in the form of instantaneous voltage and current values obtained by solving hundreds of differential equations using numerical methods. Using a script with Qlik՚s own data processing language enabled the derivation of integral energy characteristics by applying standard data aggregation functions and principles for determining effective values for alternating current circuits.
