The University

A basic inductive type high temperature superconducting fault current limiter prototype has been built and tested at the Department of Electrical Engineering of the University of Tokyo. The experimental static V-I characteristics shows a change in the impedance of the device when its limiting current is reached. A circuit model of the fault current limiter is developed by means of a non linear inductor with memory. A good agreement is obtained between numerical and experimental V-I characteristics. Dynamic characteristics are numerically studied by means of the circuit model.

In this paper, the influence of superconducting fault current limiter (SFCL, flux-coupling type) on power system transient stability is studied in detail. The influence of SFCL to transient stability of power system is studied using a model of single generator infinite bus system, different transient stability calculation results gotten with and without SFCL and with model system in different fault conditions are compared. The results show that the SFCL can effectively reduce the transient swing amplitude of rotor and extend the critical clearance time, and the application of SFCL in the power system can help to enhance its transient stability.
