“…The simulation for fault detection and mitigation based on the RFCL is based on the transmission line presented in the Simulink model of Fig. 1 were performed not by estimating the parameters of the RFCL as previously done [17], but by varying the component parameters and the short circuit current level so that the critical fault-clearing time can be estimated. The procedure for fault detection is presented first, and then the appropriate mitigation is presented next.…”

This research work proposed an improved Resonant Fault Current Limiting (RFCL) protection scheme to reduce the impact of three-phase short-circuit faults in a power system sub-transmission network. The model used an interpolator-extrapolator technique based on a Resonant Fault Current Limiter (RFCL) for automating the procedure of predicting the required reactor value that must be in resonant circuit to limit the short-circuit current values to permissible values. Using the developed model, short-circuit fault simulations on the three phases of the transmission line (Phase A-C) were performed in the MATLAB-SIMULINK environment. Simulation results were obtained by varying the resonant inductance (reactor) parameter of the RFCL circuit for each of the phases to obtain permissible short-circuit current levels and the values used to program a functional interpolator-extrapolator in MATLAB; the resonant values were typically set to values of inductance equal to 0.001H, 0.01H and from 0.1H to 0.5H in steps of 0.1H. Simulation results revealed the presence of very high short-circuit current levels at low values of the resonant inductor. From the results of simulations, there are indications that the RFCL approach is indeed very vital in the reduction of the short circuit current values during the fault and can safeguard the circuit breaker mechanism in the examined power system sub-transmission system. In addition, lower fault clearing times can be obtained at higher values of inductances; however, the clearance times start to converge at inductance values of 0.1H and above.

“…Similarly, few literatures are available on the impact of FCLs and possible remedial measures for the performance of the distance relay. In [18], the impact of resonant FCL on protection and stability is addressed, and associated parameters are estimated. In [19, 20], the impact of superconducting FCL (SFCL) on the performance of distance relay is evaluated by analytical and through simulation studies.…”

“…In paper, methods of determining location and design of superconducting fault current limiter (SFCL) have been proposed, which helps to recover system voltage of the DIFG system. Many FCL like current limiting reactors, superconducting FCL, solid state FCL, and hybrid FCL are engaged with the FRT to make the DFIG system connected during the fault . The application of the current‐limiting reactor is to introduce the reactor in series with the line for limiting the fault current.…”

Summary For enhancing the fault ride through (FRT) capability of doubly fed induction generator (DFIG), the major concern is to remain connected with the grid for maintaining the grid code. For improving this entity, saturated core fault current limiter (SCFCL)‐based protection system has been used in the DFIG system for protecting it from the fault current during fault conditions. The main features of transformer‐type three‐limb SCFCL is that the Alternating Current (AC) coils embedded across the two limbs, and the Direct Current (DC) coils embedded across the other remaining limb. The main features of SCFCL is that the core is saturated during normal operating condition, and during the fault condition, high current generates sufficient magnetic flux in the AC coil, which drives each core out of the saturation. Because of this, SCFCL operates in high‐permeability zone and increases the impedance of the AC coil, which limits the fault current. In this paper, the above behaviour of SCFCL under normal and faulty condition has been analysed by simulated mathematical modelling and verifying it with the experimental setup. In addition to conserve good FRT performance, the fault consequences in DFIG system such as rotor current, DC link voltage, and torque fluctuations are analysed. Also, the simulation result justifies the efficacy of SCFCL compared with the other conventional schemes.
