Description

technical field [0001] The invention belongs to the technical field of energy saving and loss reduction of distribution network, and in particular relates to a system and method for energy saving and loss reduction of distribution network based on big data. Background technique [0002] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. It is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some auxiliary facilities, etc., and plays an important role in distributing electric energy in the power network. The section of the power system from the step-down distribution substation (high voltage distribution substation) to the user end is called the power distribution system. The power d...

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the current manual calculation of the loss reduction rate caused by the new construction of each substation requires statistics of power generation and load conditions for a month, and the workload is very large; at the same time, the traditional power saving The loss reduction assessment method does not take into account the impact of external objective factors such as weather and location on power equipment. As far as power lines are concerned, most of them are directly exposed to the external environment. Traditional methods generally ignore the impact of external influences on power equipment evaluation calculations. For the line, there will be a certain deviation
