Impressive work Nothing else matters Impressive work Nothing else matters The model shows how to use the thin strip approximation for the superconducting coated conductors to speed up calculation. The model simulates the magnetisation of a 2G HTS stack. The T formulation is used for m …
Modeling and simulation of termination resistances in superconducting cables
by administrator on Mar 15, 2024 1:13:58 PM
The models presented here are used to simulate termination resistances which are largely responsible for the uneven distribution of currents in superconducting cables [1]. For this purpose, four different models are presented. The first is a 0D stationary model, where time enters as a …
Superconducting fault current limiter (SFCL) connected to a power system
by administrator on Mar 15, 2024 1:08:33 PM
The model can be implemented in any power system simulator (e.g., Matlab/Simulink, EMTP, PowerFactoy, etc.) for transient analyses of short circuit currents. Here one presents the method applied to MCP-BSCCO-2212 SFCL devices. The method however has already been extended to SFCL based …
Parameter-free method to extract the Jc(B,θ) field-dependence from in-field current–voltage characteristics of HTS tapes
by administrator on Mar 15, 2024 1:00:34 PM
The method presented here allows computing the critical current density (Jc) of superconducting materials from its in-field experimentally measured critical current (Ic). This is particularly important for applications like HTS cables for power transmission and fault current limiters, …
2-D electro-thermal model for simulating non-uniform quench in 2G HTS coated conductors
by administrator on Mar 15, 2024 12:57:24 PM
The model calculates the time evolution of the electric potential and the temperature in a 2G HTS CC when a transport current is applied in presence of a low Jc region (defect) in the tape. The heat generated at the defect location creates a normal zone that propagates along the tape. …
Full 3-D time-dependent electromagnetic model for Roebel cables
