Research of Typical Line Loss Rate in Transformer District Based on Data-Driven Method

Line loss rate plays an important role in evaluating the economic operation of power systems. Line loss management is one of the key management contents of power companies. Based on the existing power information system, marketing system, Production Management System (PMS) and other collection operation data, the mechanism and characteristics of the line loss of massive transformer districts are explored, and the classification criteria of the transformer district are formulated according to the different characteristics. Then, the typical transformer district is selected from the same type of transformer districts, and the line loss rate of the typical transformer district is taken as the benchmark value.
