Low-voltage power distribution network topological structure identification method based on time sequence electric quantity data

The invention relates to a low-voltage power distribution network topological structure identification method based on time sequence electric quantity data, which is technically characterized by comprising the following steps of: acquiring three-phase electric quantity data of a gateway meter of a multi-sky court area and electric quantity data of a user meter through an electricity consumption information acquisition system to construct a time sequence electric quantity data analysis matrix Z; obtaining a regression analysis matrix D by calculating the time sequence electric quantity data analysis matrix Z, arranging the regression analysis matrix D according to values of elements in the regression analysis matrix D, and judging the topological relation of the power distribution network according to the arranged regression analysis matrix D. According to the method, which item of the transformer supplies power to the electrical load of each household in the low-voltage transformer area can be quickly identif
