Optimization of fault current limiter placement using etap software

Due to the increasing power demand, the security and safety of power systems have become major challenges. Distributed energy resources have been established for solving the problem. The fault current may exceed the capacity of circuit breakers (CBs); leading to damage to CBs and even cascading incidents such as blackouts. A fault current limiter (FCL), which can be used to reduce the current surges, has attracted considerable attention from utilities. Penetration of distribution generation is inevitable one. So that to ensure the safety of the circuit breakers, super conducting fault current limiters are modeled to limit the fault current well within the limit.IEEE 30 bus system has taken as a test system for fault current limiters operation by study performed in Electrical Transient Analyzer Program.
