Application of multiple resistive superconducting fault-current limiters for fast fault detection in highly interconnected distribution systems [PDF]

, 2013
Superconducting fault-current limiters (SFCLs) offer several benefits for electrical distribution systems, especially with increasing distributed generation and the requirements for better network reliability and efficiency.

DC-bus power quality for UAV systems during generator fault conditions [PDF]

5th IET International Conference on Power Electronics, Machines and Drives (PEMD 2010), 2010
High-voltage DC-bus power quality is examined experimentally and by computer simulation during a short-circuit fault across the phase terminals of a five-phase, permanent magnet fault-tolerant generator. The DC-bus transients are seen to exceed the limits in MIL-STD-704F [1] and a control algorithm is proposed for a supercapacitor-based energy storage ...

Impact of large-scale photovoltaic-energy storage power generation system access on differential protection of main transformer under symmetrical faults

Frontiers in Energy Research, 2023
The low voltage ride-through (LVRT) requirements demand large-scale photovoltaic (PV) power generation system remain connected to the grid during faults. It results in considerable impact on the characteristics of fault current.
