“…As pointed, some of previously proposed FCL structures have ac power losses at resonant circuit in the normal condition, because of placing large inductor in the line current path [20,21]. But, the proposed structure in this paper has very low losses in the normal condition, because the inductor is bypassed by the bridge part.…”

“…Resonance type FCLs limit the fault current by using various topologies of series or parallel LC resonant circuits [18][19][20][21][22][23]. Series resonance type FCLs are composed of series connection of a capacitor and a superconducting inductor.…”

“…So, they are not commercially available, especially for third world countries. On the other hand, resonance type FCLs which do not use superconducting inductor and replace it with an ordinary copper coil, make power losses in their structures [20][21].…”

Abstract─This paper proposes a new parallel LC resonance type fault current limiter (FCL) that uses a resistor in series with the capacitor. The proposed FCL is capable to limit fault current magnitude near to pre-fault magnitude of distribution feeder current by placing the mentioned resistor in the structure of FCL. In this way, voltage of point of common coupling (PCC) does not experience considerable sag during the fault. In addition, the proposed FCL does not use superconducting inductor which has high construction cost. Analytical analysis for this structure is presented in detail and simulation results using PSCAD/EMTDC software are obtained to validate the effectiveness of this structure. Also, an experimental setup is provided to show the accuracy of analytic analyses and simulation results.

“…MOV in shunt with capacitor, with frequency tuned LC circuit has been imposed for limiting the fault-current [63]. The influence of SRFCL on enhancement of power quality of distribution system has been analyzed with MOV for good results [64]. A SSFCLs to decrease tall short-circuit current stages is planned by introducing a series impedance when the liability occurs or by turning off semiconductor devices [65].…”

Supplying quality power to consumers have been of great concern for power researchers and utilities since last few decades. Power quality issues include voltage sag/swell mitigation, harmonics reduction, load balancing, voltage flicker elimination, and fault current limiting. Various control strategies have been suggested in the literature for power quality improvement. Custom power devices are quite useful in power quality enhancement. Research on power quality enhancement has mostly concentrated on offline studies. Efforts are required to be made in power quality enhancement of real-time systems. In this paper, a survey has been presented on power quality enhancement techniques in the present scenario. The article also suggests an investigation of the role of smart metering and Phasor Measurement Units (PMUs) for power quality enhancement of real-time systems in intelligent grid architecture.

“…But, by placing a resistor ( sh R ) in series with the capacitor, transient swings of current damp quickly. Some previous structures have ac power losses at resonant circuit in no-fault condition, because of placing large inductor in line current path [9], [10]. But, this structure has very lower losses in normal condition.…”

Abstract-This paper proposes a new parallel LC resonance type Fault Current Limiter (FCL). This structure has low cast because of using dry capacitor and non-superconducting inductor and fast operation. The proposed FCL is able to limit fault current in constant value near to pre-fault condition value against series resonance type FCL. In this way, the voltage of point of common coupling (PCC) will not change during fault. Analytical analysis is presented in detail and simulation results are involved to validate the effectiveness of this structure.
