- Abstract
- Abstract: With increasing of the need for electrical engineering, some acts for enlarging the capacity of generation, transmission, and distribution shoud be done that due to raise of the amount of short circuit fault current. For reducing it some solutions can be performed that one of most effective and practical way is fault current limiter (FCL). Between all of these devices saturated-core fault current limiter (SCFCL) has an especial importance. For this type of FCL different topologies with the goal of reducing in final cost of it have been introduced. In this thesis, with regarding to this matter 2 new topologies are introduced. Also, a new method with 6 major constraints for designing of SCFCL is presented. In addition, for optimizing of the design an object function is introduced. For investigating of method 2 SCFCLs are designed base on the method and for 2 new topologies. For analyzing of the magnetic flux density in the core of SCFCL just first topology is simulated with finite elements method (FEM) in COMSOL Multiphysics software. Finally, for avalidating of the method 2 constructed SCFCL in Power System Network Simulator Laboratory of University of Tehran is installed and tested. Keywords: Fault Current, Fault Current Limiter (FCL), Saturated-Core Fault Current Limiter (SCFCL), Finite Elements Method (FEM), COMSOL Multiphysics Software.
