A new method for short-circuit fault location is proposed. The based on instantaneous signal measurement and its first second derivatives, which are the novel elements of current approach. derivatives allow associating a precise time stamp to occurrence fault. Due retardation phenomena, difference between times in registered two detectors can be used locate We offer several mathematical models ...

This paper deals with the application of artificial neural networks (ANNs) to the fault detection and location in extra high voltage (EHV) transmission lines for high speed protection using one terminal line. The neural fault detector and locators have been trained with different sets of data available from a selected power network model and simulating different fault scenarios (fault types, fa...

This paper analyses two different approaches of fault distance location in a double circuit transmission lines, using artificial neural networks. The single and modular artificial neural networks were developed for determining the fault distance location under varying types of faults in both the circuits. The proposed method uses the voltages and currents signals available at only the local end...

the study area locates between an active fault system of north anatolian in turkey and active alborz and zagros mountain ranges in iran. the total shortening concluded from arabia-eurasia collision with a rate of 22 mm/year across the ne persia is partitioned  into  two  fault  systems,  right-lateral  strike slip  movements  in  the  turkish-iranian  plateau  like  north tabriz fault system an...

Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does...

This article describes an emulation-based method for locating stuck-at faults in combinational and synchronous sequential circuits. The method is based on automatically designing a circuit which implements a closest-match fault location algorithm specialized for the circuit under diagnosis (CUD). This method allows designers to perform dynamic fault location of stuck-at faults in large circuits...

Advanced Fault Diagnosis Techniques and Their Role in Preventing Cascading Blackouts. (December 2006) Nan Zhang, B.S., Tsinghua University, China; M.S., Tsinghua University, China Chair of Advisory Committee: Dr. Mladen Kezunovic This dissertation studied new transmission line fault diagnosis approaches using new technologies and proposed a scheme to apply those techniques in preventing and mit...

[1] Double-difference locations of 8000 earthquakes from 1969–2002 on the Parkfield section of the San Andreas Fault reveal detailed fault structures and seismicity that is, although complex, highly organized in both space and time. Distinctive features of the seismicity include: 1) multiple recurrence of earthquakes of the same size at precisely the same location on the fault (multiplets), imp...
