Description

technical field [0001] The invention relates to a power grid information prediction system and method, in particular to a power grid theoretical line loss data prediction system and prediction method. Background technique [0002] The central task of the power grid enterprise is to ensure the safe, reliable, economical and high-quality operation of the power grid. Line loss rate is an important technical and economic index reflecting the management level of power grid enterprises. . Through the calculation of theoretical line loss, the economy of distribution network structure and operation mode can be identified, the components with excessive loss in the power grid and their causes can be identified, and whether the actual line loss is true, accurate, reasonable, and the actual line loss rate and technology (theoretical ) line loss rate difference, to determine the degree of unknown loss, to clarify the status quo of distribution network operation and management.
