This paper presents a procedure to obtain patterns from propagating signals in a SSSC FACTS device. The acquired patterns are suitable for neural network relay protection schemes for Fault Detection (FD), Phase Classification (PC) and Fault Zone Estimation (FZE). By considering two fault scenarios, the patterns are obtained through digital simulations which include effects of transducers and no...

The three-phase power transformer in the transmission or distribution substations represents one of essential devices on electric networks. Losing this devise cause a disconnection utility to large number electrical loads. robust protection system must be designed protect device during abnormal operations. A complete for poly-phase Karbala networks (East substation) is modeled and simulated, ad...

The paper presents the performance of a novel distributed bus differential protection scheme, which utilizes independent multi-principle advanced protection algorithms, including differential percent slope, delta phase directional comparison, rate of change of differential (ROCOD) currents, delta phase directional comparison on neutral current differential, and a check zone to secure the electr...

In this paper, we propose a novel decode-and-forward dual-relay selection technique based on Alamouti space time coding for twoway wireless relay networks (TWRNs). The twoand the threephase TWRN protocol are used in the first and second version of the proposed technique, respectively, to exchange the information symbols of the communicating terminals. In order not to waste any power for transmi...

When working with explosive materials, the worker’s hands are usually the most exposed body part and highly endangered by fragmentation effects. Several kinds of protective gloves are available. Existing standards describe testing procedures for the testing of protective gloves for mechanical risks, but seem to not realistically simulate fragmentation effects. An experimental setup was develope...

This paper studies the effectiveness of relaying for interference mitigation in an interference-limited communication scenario. We are motivated by the observation that in a cellular network, a relay node placed at the cell-edge observes intercell interference that is correlated with intended receiver’s interference. A relaying link can effectively allow their antennas to be pooled together for...

Protection history and practice has long had two relays applied for protection of one line or piece of primary equipment. The traditional approach for these relays may be to use two relays with different or identical schemes or manufacturers. There are issues of human usage and common mode failure that are considered when making a choice of how to best select these two relays. In the case of el...

Cooperative communications by pooling available resources—for example, power and bandwidth—across the network, is a distributed solution for providing robust wireless transmission. Motivated by contemporary applications in multi-hop transmission and ad hoc networks, the classical three-node relay channel (RC) consisting of a source–destination pair and a relay node has received a renewed attent...

This paper deals with fault location on three-terminal power line. The fault locator is considered as associated with the line protective relay, which communicates with the relays from the remaining line terminals and receives from them the phasors of measured threephase currents. Three subroutines of the fault location algorithm are formulated and an issue of selecting the subroutine, which is...
