Fault current limiting dynamic voltage restorer for power quality improvement in distribution system (case study: air force feeder)

Journal of Electrical Systems and Information Technology
Air force distribution feeder, or R1-G4, in Bahir Dar substation is affected by total harmonic distortion from nonlinear loads, voltage sag from short-circuit faults that occurred on the system, and voltage swell.

Coordinated Source-Grid fault current limiting strategy in HVDC grids based on fault severity and quantitative limitation demand

International Journal of Electrical Power & Energy Systems
Reliable fault current limitation is critical in high-voltage direct current (HVDC) grids due to the fast dynamics and low fault tolerance of power electronic equipment, as well as the high cost of DC circuit breakers (DCCBs). To address these challenges,

New Series Resonance Type Fault Current Limiter

, 2011
This paper proposes a new topology for fault current limiter (FCL) that is based on series LC resonance circuit. The proposed FCL uses a high speed switch to put an inductor in series with a capacitor and make resonance condition between them.

An effect of fault current limiter to distributed generator shaft torque increase under voltage sag

, 2007
Voltage sags originated at the transmission level can have a very adverse effect on distributed generators running at distribution levels. A fault current limiter (FCL) can be an effective means to limit the voltage sag impact.
