Simulation model for a novel superconducting fault current limiter

A simulation model for a novel superconducting fault current limiter is presented. The components of the novel fault current limiter are melt cast processed BSCCO 2212 tubes with shunt coils wound around them, which are connected in parallel. The simulation model is based on the electrical and thermal equivalent circuits of a component. A corresponding system of state space differential equations describes these equivalent circuits, which are coupled through several variables. MATLAB is used to solve the state space differential equation system, incorporating the material properties of the bulk BSCCO 2212 as well as the copper coil. Through a comparison of the simulation results and measured data the introduced model is validated. With the simulation model, the design of the components for a fault current limiter can be further improved.
