SIMULATION OF IGBT BASED SOLID STATE FAULT CURRENT LIMITER USING MATLAB/SIMULINK

Owing to the surge in demand for electrical energy and increase in penetration of Diesel Generators, an increase in the fault level of the power system is being observed. The employment of the FCL (Fault current limiter) has been one of the most efficient techniques for the control of fault current in recent times. This paper introduces and describes a solid-state fault current limiter which is controlled by an Insulated Gate Bipolar Transistor (IGBT). The complete design and analysis have been discussed. The simulation is done with MATLAB/Simulink software.
