  • Computer-readable recording medium storing transformer coupling phase determination program, transformer coupling phase determination apparatus, and transformer coupling phase determination method
    Patent number: 11815536
    Abstract: A recording medium stores a program for causing a computer to execute a process including: specifying, based on simulation data, related to an operation of a power distribution facility including power distribution lines and one or more transformers coupled to a phase corresponding to two of the power distribution lines, a correlation relationship between a phase current flowing through the transformer and a line current flowing through power distribution line; generating a scatter diagram indicating a degree of correlation between the phase current and each line current; calculating a probability density at each position in the scatter diagram; and determining, based on a position in a case where actual data of the phase current and the line current in the operation of the power distribution facility is plotted in the scatter diagram and a calculation result of the probability density, a coupling phase of the transformer in the actual data.
