Description

technical field

[0001] The invention belongs to the field of low-carbon power research in distribution networks, and in particular relates to an empirical method for quantifying loss reduction of energy-saving transformers based on power loss conversion. Background technique

[0002] Global warming is one of the greatest challenges facing human society today. According to the latest United Nations scientific assessment report on global climate change, the total cost of climate change will cause a loss of about 5% of global GDP. my country is a big carbon emitter, a large part of which comes from the energy sector, especially the power industry. In order to cope with global climate change, it is imperative to reduce network loss in the power grid.

[0003] The distribution capacity of China's distribution network is huge, and the distribution loss reaches 15% to 20%, and in some areas it even reaches 30%. The transformer loss in the distribution network accounts for 30% to...
