Abstract

In this paper, an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks. In this paper we are increasing the levels of inverter. If we increase the level then the efficiency will be improved and also accuracy will be improved. One good solution is, combining the fault current limiting technologies with DC breaking topologies. The application of resistive Superconducting Fault Current Limiter (SFCL) on various types of HVDCCB and can estimate the effects of combining fault current limiters on conventional DC breakers. the simulation work done for resistive SFCL and added to the DC breakers and verify its interruption characteristics and distributed energy across HVDC CB. The major advantage is that the output waveform is more close to sinusoidal and harmonics can be reduced if higher the number of the level, approximately sin wave. From the results of simulation work, maximum fault current, interruption time and dissipated energy stress on the HVDC CB could be decreased by applying SFCL. By using the simulation results we can analyze the proposed method.
