Distance characteristics for incremental quantities
arXiv:2604.16668
summary
The paper derives distance relay characteristic equations using incremental phasor quantities and a circuit model, showing that under the assumption of stationary sources the characteristics depend only on the incremental remote current and not on real‑time source voltages or injections.
Abstract
We derive distance relay characteristics in terms of incremental phasors. We use a circuit model of the network to estimate the incremental remote current. If we assume that all sources are stationary, i.e., remain periodic shortly after a fault, then the incremental remote current, and thus the characteristics, do not depend on the real-time voltages or current injections of the sources.
