Description

technical field [0001] The invention relates to the technical field of data conversion, in particular to a GIS-based distribution network line loss data collection method and a related device. Background technique [0002] The distribution network refers to a mesh power supply line network composed of multiple power supply lines, which is a large-scale power supply line. Optimizing the economic operation of the distribution network refers to rationally adjusting the load current and operating voltage of the power supply network to minimize the load on the transformer at the power supply end of the power grid and minimize the line loss of the power grid, thereby reducing the total loss of the entire power supply line. Through effective theoretical line loss calculation, it is possible to reasonably adjust the working voltage and current of the transformer at the power supply end based on the actual power demand of the power consumption place, so as to achieve the purpose of r...
