Low-Carbon Technology in Power Transformation Engineering

The goal of “dual carbon” and the goal of building a new power system also put forward new requirements for power transformation engineering. The application of various low-carbon technologies in the whole life cycle of the power transformation engineering and the construction of low-carbon or zero-carbon substation is a research hotspot at present. This paper analyzes the possible low-carbon technology and its carbon reduction benefits from three stages: design and planning, architecture and construction, operation and maintenance. In the design and planning stage, substation location is essential; In the architecture and construction stage, there are low-carbon technologies and energy-saving measures such as prefabricated building and classification and reuse of construction waste; In the operation and maintenance stage, there are various intelligent systems and energy-saving equipment such as the joint inspection system, SF6 gas replacement and low-energy transformer. It is hoped that these low-carbon technologies can provide a reference for future low-carbon power transformation engineering.
