“…The apparent impedances are then calculated by distance relays. An adaptive distance relay is proposed for protecting lines with series compensators in References 29–32. Static synchronous compensator (STATCOM) and static var compensator (SVC) affect the impedances measured by distance relays, so they can lead to over‐reach or under‐reach 33‐38 .…”

This paper proposes an adaptive characteristic for eliminating the adverse effects of fault resistance and static synchronous compensator (STATCOM) on the performance of distance relays in transmission line and collector lines of doubly-fed induction generator (DFIG)-based wind farms in the case of singlephase-to-ground resistive faults. The proposed method improves the performance in distance relaying and maintains the coordination between relay pairs in the transmission line and wind farm collector lines. In this method, an adaptive coefficient that can modify the zone settings of conventional distance relays is added to their characteristic to improve the accuracy and coordination under the mentioned conditions. Using analytical relationships and numerical results from simulations in Matlab/Simulink environment, the efficiency of the proposed method is confirmed.

A hybrid scheme for transmission line protection (HSTLP) using the Stockwell transform (ST), Wigner distribution function (WDF), and alienation coefficient (ACF) is designed. Current signals are analyzed using the ST, WDF, and ACF to compute the Stockwell fault index (SFI), Wigner fault index (WFI), and alienation coefficient fault index (ACFI), respectively. These fault indexes are used to derive a hybrid signal processing fault index (HSPFI), which is implemented for the detection of transmission line fault events. The peak magnitude of HSPFI is compared with a preset threshold magnitude (TH) to identify the fault. The statistical formulation is proposed for fault location on the power transmission line. Fault classification is achieved using the number of faulty phases. A hybrid ground fault index (HGFI) is used to recognize the involvement of the ground during the fault event. This HGFI is determined by processing zero sequence current using ST and WDF. The performance of algorithm is tested by various case studies for fault impedance variation, variable sampling frequency, fault incidence angle variation, reverse power flow on transmission line, highly loaded line, different fault locations online, and noisy conditions. The algorithm is also validated to detect a fault on a practical transmission line of large area utility grid of Rajasthan Rajya Vidyut Prasaran Nigam Limited (RVPN) in India. The algorithm performs better than the Hilbert–Huang transform (HHT)-based protection scheme and wavelet transform (WT)-based protection scheme available in the literature in terms of mean error of fault location, fault location accuracy, and noise level. The proposed protection scheme efficiently detected, classified, and located the faulty events such as single-phase-to-ground fault (SPGF), two-phase fault (TPF), two-phase-to-ground fault (TPGF), three-line fault (TLF), and three-line-to-ground fault (TLGF). Transmission line fault location accuracy of 99.031% is achieved. The algorithm performs well even with a high noise level of 10 dB SNR.

“…Arvind et al presented an adaptive distance protection scheme using the information of shunt injected current by STATCOM connected at midpoint of the transmission line. Global Positioning System (GPS) with fibre optic was used for communicating between the local relay and STATCOM, thereby reducing the time lag for data communication, while Dhenuvakonda et al used phasor measurement unit (PMU) algorithm with static synchronous series compensator (SSSC) connected at the midpoint to analyse its effect on a double circuit transmission line protection scheme.…”

Summary The performance of conventional distance protection schemes is adversely affected by the infeed and outfeed current, which causes distance relay to underreach or overreach. The objective of this paper is to analyse a typical conventional distance scheme and then present a novel method to address the problem of underreach or overreach. An adaptive protection scheme is proposed using radial basis function neural network (RBFNN), which automatically adjusts its relay operational settings based on acquisition of remote end infeed data from the remote substation using remote terminal units (RTUs) connected to the field instruments (current transformers [CTs] and voltage transformers [VTs]). Communication between the local and remote end substation RTUs is through fibre optic. The results of this new technique, using Alaoji (in Nigeria) 132‐kV subregional network, are presented based on NEPLAN and MATLAB software simulations, which show significant improvement.
