the oudna field part of the offshore northeastern tunisia, straddles between two structural domains, the tunisian atlas to the north and the pelagian sea to the south. the study of this field has confirmed adequate petroleum system in fahdene formations (albian-cenomanian) and birsa (serravallian) resulting from the combination of several sedimentary, tectonic and thermal factors. to do this, w...

in current paper, geometrical relationship between the longitudinal faults of a zone of the folded zagros, surrounding asef mountains (north of shiraz) that follow the northwest-southeast structural trend (eg. zarghan, katah and sadra faults) has been studied. a western and southern zone of zagros mountain chain called folded zagros has a length of about 1375 km and a width between 120 and 250 ...

This paper presents a new approach for Loss of Excitation (LOE) faults detection in Hydrogenerators using Adaptive Neuro Fuzzy Inference System. The proposed scheme was trained by data from simulation of a 345kV system under various faults conditions and tested for different loading conditions. Details of the design process and the results of performance using the proposed technique are discuss...

Power transmission and distribution lines are the vital links that achieve the essential continuity of service of electrical power to the end users. Transmission lines connect the generating stations and load centers. As the generating stations are far away from the load centers they run over hundreds of kilometers. Hence, the chances of fault occurring in transmission lines are very high. Sinc...

western parts of the chaharmahal and bakhtiyari province (ardal county) due to containing high mountains, deep valleys and small intermountain plains as well as the placement in the path of the nomads have long been of interest to humans. the nomadic communities of the mountainous regions of chaharmahal va bakhtiyari culturally interacted with the lowland areas of fars and khuzestan's plai...

This paper describes a new, high-speed protection for EHV transmission lines. The presented scheme also performs well on series compensated lines. The High speed distance protection (ZMFPDIS) function is a six zone full scheme protection with three fault loops for phase-to-phase faults and three fault loops for phase-to-earth faults for each of the independent zones, which makes the function su...
