This paper presents an improved algorithm for fault detection and classification of transmission line fault current signals using MATLAB/SIMULINK. The proposed algorithm presents a fault discrimination method based on the three-phase current and voltage waveforms measured when fault events occur in the power transmission-line network. The algorithm for fault classification employs wavelet multi...

This paper analyses the method to limit fault currents and pre fault bus voltage by the use of Thyristor Controlled phase Shifting transformer (TCPST). The mathematical model of power system equipped with TCPST was systematically derived. The magnitude of the series reactance plays a very important role to limit the short circuit current, as well as TCPST inject a series voltage which reduces t...

The current energetic and economic context brings the need of a proper asset management of power generation facilities and components. This paper is intended to provide a wide view of the state of the art in asset management, with a special focus on fault detection and diagnosis. The different stages involved in asset management are defined and arranged as layers over the supervised process: Ac...

The North Tabriz Fault is seismologically an active fault with current right lateral strike-slip movements. Restricted mafic to intermediate Late Cretaceous igneous rocks are exposed along the North Tabriz Fault. Whole rock samples and clinopyroxene phenocrysts geochemistry were studied in order to characterize the petrogenesis of these mafic rocks and their possible relation to an oceanic crus...

Increase in power generation capacity of electric power systems has lead to increase in the fault current level which can exceed the maximum designed short-circuit ratings of the switchgear. All the equipment therefore must have a short-circuit rating capable to withstand this level. Short-circuit currents contain extremely high energy and can damage electrical equipment. Typically, the circuit...
