Abstract
This paper focuses on the application of high-temperature superconducting (HTS) cables in ultra-high voltage direct current (UHVDC) transmission, investigating the main sources of DC transmission losses and the mechanism of energy consumption during the transmission process. It analyzes the role of HTS cables in reducing line resistance losses, minimizing energy attenuation, and improving transmission efficiency. By comparing the technical characteristics of conventional cables and HTS cables, the paper demonstrates the advantages of HTS cables in long-distance and high-power transmission scenarios, and proposes targeted loss suppression measures, including optimizing the performance of cable materials, improving cooling systems, and enhancing the overall operational stability of the system. HTS cables can significantly reduce energy losses, providing technical support for the efficient, safe, and green development of UHVDC transmission.
Key words： High-temperature superconducting cable; Ultra-high voltage direct current (UHVDC) transmission; Loss suppression; Transmission efficiency
