This paper shows a solution for controlling shortcircuit currents of a power electronic based Fault Current Limiter (FCL). A model for control design of three-phase short-circuit currents will be presented. A way of limiting the maximum aperiodic short-circuit current is derived with special regards to the stability of the entire system. Control designs of singleand two-phase shortcircuit curre...

Smart grid is the most significant topic in power system due to numerous benefits. integration of distributed generation. DG plays an important role different configurations either connected mode or islanded mode. Multiple will result fault currents this may lead damage existing protective devices. In paper Fuzzy used optimally locate and Jaya a new optimization technique adapted size Fault cur...

The fault current levels through the electric devices have a significant impact on failure probability. New fault current results in exceeding the rated capacity of circuit breaker and switching equipments and changes operation characteristic of overcurrent relay. In order to solve these problems, SFCL (Superconducting Fault Current Limiter) has rising as one of new alternatives so as to improv...

The experimental results of the use of a liquid lithium limiter on FTU are presented. To avoid droplet generation by JxB forces we have adopted a limiter with a capillary porous system configuration. Lithization of the vacuum vessel is performed by exposing lithium limiter to the plasma boundary for three subsequent plasma discharges after that it is extracted. Strong reduction of the recycling...
