Abstract

The invention discloses a power distribution network transformer carbon footprint analysis method based on life cycle evaluation, which is based on a life cycle evaluation method, takes a transformer with the capacity of 200kVA as an example, calculates the carbon emission and the total energy demand of the whole life cycle, and further analyzes the carbon emission in each stage. Research finds that the carbon emission with the highest proportion is the operation stage and accounts for 99.03% of the whole life cycle, the waste recovery stage effectively reduces the influence of the carbon emission on the environment, the technology in the production and manufacturing process is improved, more energy-saving and efficient devices are adopted, and the carbon emission can be effectively reduced. Sensitivity analysis shows that the silicon steel sheets have obvious influence on carbon emission in the life cycle of the power distribution network transformer, and the higher the silicon steel sheets are, the lower the carbon emission is.
