Abstract

Abstract:

Quantitative analysis of carbon emission due to power transmission and transformation project construction is the premise and basis of green low-carbon implementation of the project. Based on quantification framework and data processing method according to the GHGP standards, a common hierarchic quantization model and a boundary optimization model for power transmission and transformation engineering construction are developed in this paper, in addition, the behavior of carbon emission from transmission and transformation project construction is analyzed and optimized through hierarchical quantification based on the sub-projects, material flow and energy flow activities by taking a certain 500 kV substation project as an example. The results show that the full-scale distribution characteristics of carbon emission is obtained through the quantification model, the carbon emission from civil and architectural engineering works accounts for 93.02% of the total carbon emission. Compared to energy flow, the carbon emissions from material flow activities accounted for 90.28% of the total emissions, of which the carbon emissions from cement and its products and steel consumable materials accounted for 81%. When the carbon emission significance threshold is set to 0.002% ~ 0.018% of the total emissions, 90% of the unit data flow of power transmission and transformation engineering construction can be excluded from the quantification boundary. When renewable concrete and recycled steel are used in the construction of power transmission and transformation projects, significant emission reduction can be generated.

Key words: civil and architectural engineering works, installation engineering works, material flow, energy flow, the quantification of carbon emission
