Probabilistic-statistical analysis of the maximum electrical load of apartment

Abstract

This paper presents the analysis of distribution of a random variable of the maximum electrical load of the apartment in apartment building during the weekday in the winter season. Results of actual measurements of electrical load at the entrance to the apartment on weekdays were processed and analyzed during the research. Typical time intervals, when the maximums of electrical load were observed, were highlighted based on the obtained data. Hypotheses of distribution law of a random variable of the maximum electrical load were proposed for those intervals. In the next stage of work the results of determination of the distribution law were checked with Pearson's chi-squared test. As the result of the survey, the numerical characteristics of distribution law of the maximum electrical load were presented, as well as the time intervals, when those maximums were observed.
