Abstract :
In order to introduce the high temperature superconducting fault-current limiters (SFCL) into electric power systems, we need a way to conveniently predict the limiting characteristic in a given situation. The most important physical property dominating the current limiting behavior of the SFCL is the electric field-current density (E-J) characteristics of high temperature superconductors (HTS) which is dependent on temperatures. So we have developed an EMTP/ATP model of high temperature resistive type SFCL using MODELS language based on E ∼ J characteristics of HTS. Real-time circuit current is as an input signal to the SFCL model, and the output of the model is controlled by a TACS-controlled time-dependent resistance. The operating characteristics and limitation behaviors of SFCL have been investigated in detail.
