Research on Carbon Emission Accounting Method and System for UHV Substation Full Life Cycle

As an important hub for large-scale, long-distance power transmission, the construction, operation and maintenance of UHV substations involve energy consumption and carbon emissions. It is necessary to quantitatively measure the carbon emissions of UHV substations throughout their life cycle to provide basic data support for the formulation of an overall emission reduction strategy. This paper first clarifies the carbon emission boundaries and characteristics of UHV substations from design, transportation, construction, operation to decommissioning. Based on this, a comprehensive and accurate carbon emission accounting method is constructed, covering carbon emission calculation models in many aspects such as energy consumption, material use, and transportation process. At the same time, At the same time, we designed and implemented a full life cycle carbon emission accounting system for UHV substations, and the effectiveness of the system is verified in terms of response time, reliability, and robustness through experimental applications. The research results verify the applicability of the UHV substation life cycle carbon emission accounting method constructed in this paper, which can process, convert and calculate the carbon emissions of UHV substations throughout their life cycle, provide a scientific basis and strong technical support for energy conservation and emission reduction of UHV substations, and help the green and low-carbon development of the power grid engineering.
