TECHNICAL FIELD
[0001] The present application relates to the technical field of basic carbon emission calculation of power transmission line construction, and more particularly to a basic carbon emission calculation method for overhead power transmission line construction. BACKGROUND
[0002] The power transmission line is used to realize the connection of the power transmission line by the transformer to the power transmission line through the circuit breaker and other control devices. The power transmission line is divided into overhead power transmission line and cable line in structure. The carbon emission refers to the greenhouse gas emission generated in the production, transportation, use and recycling of a product. Whether it is an overhead power transmission line or a cable tunnel line, a certain amount of carbon emission will be generated in the construction process. Therefore, how to accurately calculate and utilize the carbon emission value required for construction is an important link in the process of power grid management.
[0003] The patent with the application publication number CN119623834A discloses a basic carbon emission calculation method for overhead power transmission line construction. The effective calculation method for the basic carbon emission of the overhead power transmission line construction is proposed by combining the emission factor method with the characteristics of the power transmission line foundation engineering. The method is applied to the carbon emission calculation of the slab-column foundation and the excavated foundation, and the potential energy-saving and emission-reducing links and modes are explored.
