High-timeliness low-voltage transformer area line loss prediction method

The invention discloses a high-timeliness low-voltage transformer area line loss prediction method, which comprises the steps of transformer area electric quantity data extraction, acquisition failure user missing daily electric quantity transverse change value calculation, longitudinal change value calculation, weight factor calculation, acquisition failure user daily electric quantity complementation and transformer area comprehensive line loss rate calculation to realize T-1 low-voltage transformer area line loss prediction. According to the method, for transformer area acquisition abnormity, in combination with data such as a list of users failed in acquisition and historical electricity consumption of the users, the daily electricity quantity of the users failed in acquisition is fitted and complemented, the electricity quantity influenced by acquisition failure is estimated, transformer area daily line loss trial calculation is carried out, and a T-1 transformer area line loss early warning and predicti
