This paper presents a life cycle assessment-based carbon emission analysis method for a 110 kV integrated energy station. Life cycle carbon emission calculation of the transformer equipment, solar photovoltaic system, energy storage system, and charge station in the integrated energy station is carried out. Result shows that carbon emissions in the operation and maintenance phase account for the largest proportion, and carbon emissions mainly come from the transformer equipment. The analysis results are helpful for designers to take corresponding measures to realize the low-carbon living and the low-carbon operation of the integrated energy station.
