Influence of DC Component Time Constants on Asymmetrical Fault Interruption of 126 kV SF6 Circuit Breakers

IEEE Transactions on Power Delivery, 2023
Recently, the time constant of the DC component of short-circuit current exceeds the standard time constant of the circuit breakers (CBs) significantly in high voltage power systems. This may cause severe economic losses due to interrupting faults.

A Phasor Estimation Algorithm Robust to Decaying DC Component

IEEE Transactions on Power Delivery, 2021
Phasor measurement is widely used in fault detection and localization of power systems. To improve the phasor measurement accuracy when the fault signal contains the decaying dc component (DDC), this article proposes a half-cycle DFT (HCDFT)-based phasor

Removal of System and CT Decaying DC Component in Fault Signal Using Selective Interval Integration

IEEE Transactions on Power Delivery, 2022
The fundamental current component at the secondary side of current transformer (CT) is often accompanied with decaying direct current (DC) component produced by the system and the CT.

A Novel Sub-Cycle-Based Method for Estimation of Decaying DC Component and Fundamental Phasor

IEEE Transactions on Instrumentation and Measurement, 2021
Accurate estimation of the fundamental phasors of voltage or current is a challenge to power system engineers. It becomes even more challenging when the decaying dc component (DDC) is present in the signal.
