“…The capability to also accurately capture the temperature gradients around a hot spot is enabled by the use of a static non-uniform spatial grid along the axis. In [55] the same model is applied to investigate the cool-down time of the cable, with various GHe flow rates. The work in [54] is extended also in [56,57] to include a 1D equation for the pressure drop along the GHe cooling channels, the differential form of which is reported in equation ( 13):…”

“…In order to realize the large-scale application of medium-and highvoltage DC networks for ships, it is necessary to overcome the technical bottlenecks, including the design and development of key equipment, grid optimization and safety protection, as well as the development of corresponding specifications and standards systems [103][104][105]. In the selection of key DC equipments (e.g., DC circuit breaker, DC cable, high-voltage high-power converter, and DC current limiter), the current development level of equipment still cannot meet the application-based requirements of medium-and high-voltage DC networks [106][107][108][109]. For example, the current DC network for ships often adopts the E-PP technology.…”

“…In these works, Newton-Raphson and Runge-Kutta methods are used for the steady-state and transient numerical solution, respectively. VEM approach gains ground even in the most relevant studies [140,141] for transient thermal analysis of HTS cables. Finally, recent efforts on the same topic use multi-physics software as COMSOL R [142], 4-C code [143] or thermal network methods (TNM) to determine temperature distribution over superconducting power equipment [144].…”

“…Occurrence of transient over voltages needs to be considered for termination and protection system designs for electric ships using HTS power cables. More recently, in [140] and [141], detailed transient thermal analysis of HTS dc cables was presented and system contingencies in which the system undergoes a transition that may lead to quenching were studied. It is shown that transient models for several potential contingencies are useful tools for design, operational protocol, and managing HTS cable systems potentially serve several critical loads.…”
