Microgrids are able to dispatch power distribution systems with the advancement of electronics-based inverters. As per IEEE-1547-2018 standards, Microgrid has maintain voltage 0.88 < V 1.1 p.u (per unit) and frequency 58.8< f_0 61.2 Hz detect un-intentional faults in less than 2 seconds bring into islanding mode seamlessly. Unless these detected is islanded, system stability cannot be maintaine...

Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The crystal structure of the Ni(II) complex has been determine...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...

Using PSPICE a resonant dc-dc converters operating at constant frequency was simulated. The paper concentrates on the working of a half bridge topology employing ZVS techniques. The operation of converter with LC filter in the output is discussed. The design and fabrication was done on a 5V, 50W converter using MOSFET to validate the performance of the converter. The converter has illustrated l...

Due to the increased integration of distributed generations in networks, their development and operation are facing protection challenges that traditional systems incapable addressing. These problems include variations fault current during various modes, diverse network topology, high impedance faults. Therefore, appropriate reasonable detection is highly encouraged improve dependability networ...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

Unsymmetrical dimethylhydrazine (UDMH) is very toxic and hard to decompose in traditional ways. In this paper, the gasification of unsymmetrical supercritical water was studied a batch reactor under different conditions. The hydrogen production process UDMH metal containers multiphase reaction process. effects temperature, alkaline catalysts, residence time, oxidation on were systematically stu...

the nnw-trending dena fault, with 140 km length, cuts the major structures of zagros fold-thrust belt in borujen region. the fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. this study presents a new interpretation for the kinematics of dena fault based on field evidence....
