An Optimization-based Protection Strategy in Active Distribution Network using Double Dual-Setting Directional Overcurrent Relays to Increase DG Penetration [PDF]

open access: yesInternational Journal of Research and Technology in Electrical Industry, 2023
Coordination between protection devices is one of the important issues in any protection scheme of an electrical power system. The tendency to increasingly use distributed generation has jeopardized the selectivity of overcurrent relays in active ...

Overcurrent and Directional Overcurrent Protection for Microgrid

open access: yesAndalasian International Journal of Applied Science, Engineering and Technology, 2023
Microgrids will become common in future electrical distribution networks. Numerous operating modes that occur in microgrids make the development of protection schemes and settings challenging.  This paper aims to develop a simple protection scheme for the Microgrid IEC Benchmark without any expensive equipment such as communication apparatus.

Influence of the converter transformer valve-side bushing fault on commutation reactance protection and improvement scheme [PDF]

open access: yesArchives of Electrical Engineering, 2023
Commutation reactance is an important component in the voltage-source converter- based high-voltage direct current (VSC–HVDC) transmission system. Due to its connection to the converter, when there is a fault occurring on the valve-side bushing of a ...

Analysis and hardware testing of cell capacitor discharge currents during DC faults in half-bridge modular multilevel converters [PDF]

open access: yes, 2015
This paper focuses on the behaviour of the cell capacitor discharge currents during DC faults in half-bridge modular multilevel converters. Active switches, not designed for fault conditions, are tripped to minimize discharge currents effect on the ...
