The invention discloses a transformer area user relationship error correction method based on correlation analysis, and belongs to the technical field of electric power. At present, a good method forjudging suspected errors of a transformer-user relationship does not exist, and obviously, the requirements of customer marketing management under metering big data cannot be met. According to the method, the correlation coefficient of the daily electricity consumption/transformer area total meter electric quantity and the transformer area line loss rate is calculated, if the daily electricity consumption/transformer area total meter electric quantity of the user is in negative correlation with the transformer area line loss rate, suspected transformer area relation errors of the user are preliminarily judged, and finally on-site checking is conducted on a transformer user relation error list. According to the method, a user list of incorrect transformer-user relationship is obtained through a big data analysis method by using user electricity consumption data and transformerarea line loss rate data; the objective of accurately positioning the user with the incorrect transformer-user relationship is achieved, the judgment accuracy rate of the incorrect transformer-user relationship reaches 70% or above, meanwhile, the line loss rate of a transformer area is correct and calculable,and technical support is provided for lean marketing management.
