“…The settings of this operating characteristic cover 80% of line length as first zone (zone-1). Conversely, second (zone-2) and third zone (zone-3) cover 120% of the total line length and 100% of the adjacent line length, respectively [41]. The operating region of the quadrilateral relay for zone-1, zone-2 and zone-3 has been decided by K 1 , K 2 , and K 3 , respectively.…”

“…9a shows the case that B-C fault occurs at 60% of line 1 with R f = 10 Ω. The reach values for quadrilateral characteristic are adopted from [30]. As seen, in the case of HSFCL does not exist in transmission line, both quadrilateral and mho characteristics detect the occurrence the fault.…”

“…Still, it demands synchronized measurements from all line terminals, which increases considerably the protection infrastructure's complexity compared to solutions that use data from only one terminal. Reference [8], on the other hand, presents an algorithm that has an adaptive complex-plane characteristic that is not affected by the fault resistance, but like the other adaptive zone methods, it also needs robust real-time processing.…”

This paper presents a distance protection method based on estimating the resistances and inductances seen by the relay using a least-squares (LS) approach combined with the application of Bayesian inference (BI) to determine fault probabilities in the protected zone over time. The use of BI in the presented algorithm increases the security and reliability of the LS-based line protection approach, which, although fast, may yield impedance estimates with numerical inaccuracies and therefore configures a solution capable of detecting faults internal to the protected zone rapidly and dependably. The authors tested the proposed algorithm using data sets obtained from transmission line fault simulations performed in Alternative Transients Program (ATP), which considered noisy measurements, current transformer (CT) saturation, capacitive-coupling voltage transformer (CCVT) transients, switching onto fault, close-in faults, frequency variations, uncertainties in the line’s parameters, and power swings. Furthermore, the authors tested the presented method against measurements recorded by field protection equipment during seventy-nine actual fault events on four existing 500 [kV] lines. The results indicate that the proposed algorithm is a fast, secure, and reliable distance protection solution and that using BI to the LS-based distance protection approach increases security while maintaining fast fault detection.
