This paper presents a new approach for locating fault in transmission line using intelligent control relaying. Fault must be detected at its inception by issuing an output signal indicating this condition. Neural network approach for locating fault can be posed as a pattern-recognition to recognize pure sinusoidal signals as indicators of a normal system condition; abrupt changes of amplitude, ...

This paper presents a novel approach to fault detection, faulty phase(s) identification, faulty section estimation, and fault location determination for a multi-ended transmission line in Egypt based on artificial neural networks. In order to perform this approach, the protection task is subdivided into different neural network modules for fault detection, fault classification as well as fault ...

Previous research has shown that Rasmussen’s abstraction hierarchy, which consists of both physical and functional system models, provides a useful basis for interface design for complex human—machine systems. However, very few studies have quantitatively analysed how people allocate their attention across levels of abstraction. This experiment investigated the relationship between attention al...

The necessity of using several components in multilevel inverters jeopardizes the reliability their operation. Hence, aim this article is to propose a novel single-phase fault-tolerant topology based on switched-capacitor concept ensure robustness converter occurrence fault. proposed single-source steps up input voltage seven times with simple control strategy. Fault tolerance achieved by consi...

[1] The role of phyllosilicate fabrics in fault gouge is a poorly understood component of the mechanical and hydrologic behavior of brittle fault zones. We present 90 fabric intensity measurements using X-ray texture goniometry on 22 natural clay-rich fault gouges from low-angle detachment faults (Death Valley area detachments, California; Ruby Mountains, Nevada; West Salton Detachment Fault, C...

Modern manufacturing facilities are large scale, highly complex, and operate with large number of variables under closed loop control. Early and accurate fault detection and diagnosis for these plants can minimise down time, increase the safety of plant operations, and reduce manufacturing costs. Fault detection and isolation is more complex particularly in the case of the faulty analog control...

Tectonic implications of subcrustal, normal faulting earthquakes in the western Shikoku region have been investigated in sorme detail, mainly based on the faulting mechanism of the Bungo channel earthquake of August 6, 1968 (M=6.6, h=45km) and its aftershocks. A synthetic study of the focal mechanism solution, spatial distribution of aftershocks, seismic waves observed in the near and far field...

The 11 March 2011 Mw9.0 Tohoku-Oki earthquake was recorded by an exceptionally large amount of diverse data offering a unique opportunity to investigate the details of this major megathrust rupture. Many studies have taken advantage of the very dense Japanese onland strong motion, broadband, and continuous GPS networks in this sense. But resolution tests and the variability in the proposed solu...

Self–repairing digital systems have received increased attention as the modern systems are becoming more complex and fast. For systems operating in harsh and/or hostile environments even a single failure event can result in huge loss and disastrous effects. Availability of a system can be increased by making it capable of detecting and recovering from faults, i.e. make it fault tolerant. In thi...
