Comparative Analysis and Research on Carbon Emission of Substation Cast-In-Place and Prefabricated Building Based on Carbon Emission Model

In order to help the ' carbon peak, carbon neutrality ' dual carbon target, the power industry, as a major carbon emitter, is actively promoting the construction of a new power system. For substation projects, the construction of green zerocarbon substations is an important trend for future development, and it is also the only way for the corresponding national sustainable development strategy. It is of great scientific significance to promote the modular construction of substation assembly by quantifying and comparing the carbon emissions of cast-in-place buildings and prefabricated buildings in substations. Through the analysis of the carbon emission sources of cast-inplace buildings and prefabricated buildings in substations and the research of construction technology and transportation vehicles, the carbon emission model of substation building stage is established. Based on the model, two substation distribution equipment buildings with different construction methods are selected and their carbon emissions in the materialization stage are calculated. The calculation results show that in the materialization stage, the prefabricated building can reduce carbon emissions by 99.33 kg per unit building area compared with the cast-in-place building. This research result provides a theoretical basis for the promotion of green construction technology in substations.
