System dynamics-based whole life cycle energy consumption and cost analysis of a typical cable project with near-zero consumption construction project

Cable engineering, as a key link in the transmission of electrical energy, involves huge electrical energy consumption during its construction and operation phases. In order to reduce the energy loss and carbon emission of cable engineering, in-depth research on near-zero energy consumption technology in the whole life cycle of cable engineering has been carried out. While addressing the near-zero-energy construction of cable projects, we aim to carry out a study on the whole life cycle cost and carbon emission of the green construction process, which includes the production and transportation of materials and equipment, the construction, installation and commissioning phases, the operation and maintenance phases, and the disposal phase, taking into account the costs of these four phases. By comprehensively analyzing the costs and carbon emissions of each stage and introducing the carbon index to analyze the green economy of the scheme, we can achieve a dynamic balance between minimizing the costs and minimizing the carbon emissions of the cable project in long-term operation, and provide profound and practical support for the realization of the dual-carbon target and the promotion of the energy transition.
