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. …
