Fault Coordination Control for Converter-Interfaced Sources Compatible With Distance Protection During Asymmetrical Faults

IEEE Transactions on Industrial Electronics, 2023
In this article, distinctive fault characteristics of converter-interfaced renewable energy sources (CIRESs) will result in the misoperation of traditional distance relays. To handle this issue, a new fault coordination control method is proposed to ensure the correct operation of distance relays.

Signals Passing Through Asymmetric Faults in Transmission Lines

IEEE Sensors Journal, 2021
Unexpected results have been seen in multiple papers involving spread spectrum time domain reflectometry (SSTDR) measurements on twin lead cables with one line containing a fault. A small portion of the signal is able to transmit past the fault, reflect off the end of the cable, return back through the fault, and be recorded by the SSTDR.

Induction Machine Emulation under Asymmetric Grid Faults

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
Machine emulation is the concept of developing a virtual machine in real time with power-hardware-in-the-loop (PHIL) technology. This process of emulation allows testing the variable speed drive or drive inverter or the performance of grid without using a real machine.

Fast generator protection against internal asymmetrical faults

IEEE Transactions on Power Apparatus and Systems, 1977
An on-line digital computer technique for the protection of a generator against internal asymmetrical faults is described in this paper. The proposed technique relies on the detection of a second harmonic component in the field current at the onset of a fault in the armature winding.
