Abstract

The invention provides a line loss management method and system based on topology rectification, a storage medium and equipment. The method comprises the following steps: establishing a topology structure diagram according to an equipment distribution relation in a line single line diagram; calculating a theoretical line loss rate of the line according to the topological structure diagram, the equipment parameters and a pre-trained forward-backward substitution load flow calculation model; judging whether the theoretical line loss rate of the line is higher than the standard line loss rate; and if yes, returning to modify the topological relation and the equipment parameters in the topological structure diagram, and recalculating the theoretical line loss rate of the line until the theoretical line loss rate of the line is not higher than the standard line loss rate. According to the line loss management method and system based on topology rectification, the storage medium and the equipment, whether the theoretical line loss rate of the line is higher than the standard line loss rate or not is judged, and the topological relation and the equipment model are repeatedly corrected until the theoretical line loss rate of the line is not higher than the standard line loss rate, so that the theoretical line loss of the line is reduced, and the economic and energy-saving effects are achieved.

Description

technical field [0001] The invention relates to the technical field of theoretical line loss calculation of distribution lines, in particular to a line loss management method, device, storage medium and equipment based on topology correction. Background technique [0002] With the rapid development of my country's economy, the pace of development of my country's electric power industry has gradually accelerated. Power distribution systems generate line losses during operation. Line loss refers to the energy loss dissipated in the form of heat energy, that is, the active power consumed by resistance and conductance. Among them, the theoretical line loss is the line loss obtained by theoretical calculation according to the parameters of the power supply equipment, the operation mode of the power network at that time, the power flow distribution and the load situation. [0003] The line loss of the power distribution system is not converted into useful energy and is wasted. ...
