In this paper a hybrid active DC line conditioner for fluctuations and ripples reduction in voltage and current of DC power systems is proposed. Malfunctions in operation of equipments and systems which are supplied by low quality distribution power systems are one of the main effects of DC voltage ripple. In the proposed configuration a hybrid system including series and shunt active line ...

The interconnection of transmission, distribution, and generation lines has established a structure for the power system that is intricate. Uncertainties in active flow are caused by changes load growing dependence on renewable energy sources. study presented this paper employs several controlling strategies to reduce frequency variations series-compensated two-area systems. Future systems will...

A subgridding formulation of Agrawal coupling equations of transmission line with branch and distributed electromagnetic excitation is proposed. This algorithm enables us to solve the transmission line system using different temporal and spatial step on different branches. The method is used to calculate the lightning induced over-voltage on the transmission line installed with air gap componen...

Optical phase conjugation is demonstrated to enable simultaneous wide-band compensation of the residual dispersion and the fiber nonlinearities in dispersion-managed fiber transmission lines employing slope-compensating fibers. When the dispersion slope of transmission fibers is equalized by slope-compensating fibers, the residual dispersion and the slope of dispersion slope are compensated by ...

In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

This paper studies the issues of apparent fault loop impedance seen by distance relays protecting a series compensated line with Series Capacitors (SCs) and their Metal-Oxide Varistors (MOVs) installed in the middle of the line. In this paper, SCs&MOVs schemes are equivalented for the fundamental frequency and taken into account in the measurement of the fault loop impedance. Two different appr...

We consider the modulated harmonic wave in discrete series connected Josephson transmission line (JTL). formulate approach to modulation problems for equations based on calculus. check up by applying it Fermi-Pasta-Ulam-Tsingou type problem. Applying JTL, we obtain equation describing amplitude, which turns out be defocusing nonlinear Schr\"odinger (NLS) equation. compare profile of single soli...
