The protection of series compensated lines, in particular with capacitors located at the end of the line, present many difficulties. The satisfactory setting of line and capacitor protections requires time domain simulations including the protection model. In most complicated cases, the connection of the real protections to digital or analogical simulators becomes necessary. Using this approach...

آنتن های زیادی با سطح مقطع استوانه ای وجود دارند که در کنار یا روی آنها تعدادی عنصر تابنده با طول محدود وجود دارند. این ساختارهای تقریبا استوانه ای را می توان با روش ‏‏‎s2ds(spectrum of two dimensional solutions)‎‏ تحلیل نمود. به این ترتیب که با استفاده از تبدیل فوریه نسبت به محور استوانه (محور ‏‎z‎‏ )، مسئله الکترومغناطیس سه بعدی اینگونه آنتن ها را می توان بصورت عکس مسائل دو بعدی با تغییرات ها...

In the present paper, a new scheme for damping torsional modes in a series compensated power system has been developed. The proposed scheme, utilizes the effectiveness of combined active power and frequency (C.A.P.F.) SVS auxiliary controller in co-ordination with an induction machine damping unit coupled to the T-G shaft. Studies are conducted on the first IEEE benchmark model. The damping sch...

Accurate and robust fault location algorithm for parallel lines compensated with one three-phase bank of series capacitors in each the line is presented. The algorithm is categorized as one-end fundamental frequency based technique which offsets the series compensation effect and the reactance effect resulting from the remote end infeed under resistive faults as well as takes the countermeasure...

We address the problem of on-line sprite-based video coding in cases where scene segmentation is not available a priori or transmission of such segmentation information cannot be afforded due to low bit rate requirements. We propose an on-line segmentation method that can be integrated into an MPEG4 online sprite based video codec. The proposed method uses macroblock types as well as motion com...
