The quality of electric power supply is based on safety, reliability, the accuracy and constancy of electric parameters (frequency, sign shape, amplitude), and economic distribution of the produced power, keeping the losses as low as possible. One of the results of the growing user demand for electric power, is the growth of the fault currents. Handling these high current faults is an ever-growing challenge.

For many problems of modern time power engineering, superconductivity can provide an alternative solution. One of the most developing areas of superconductive devices, are the fault current limiters (FCL). FCLs already exist in many different forms. One of the most common types is the high temperature superconductive inductive type fault current limiter (HTS FCL). In my thesis work I deal with only this specific type of current limiter.

The aim of my work is to create a computer code that can be used during the design above-mentioned FCL units. The program helps defining the basic parameters of the iron core and copper winding, and creates a 2D model for further finite element (FEM) simulation.

A designer program like this can make further researches (either by student or by faculty tutors) easier, which researches can result in the up-speeding of the industrial introduction of superconductive devices, or the appearance of new types and ideas.
