Shunt FACTS devices are used for controlling transmission voltage, power flow, reducing reactive losses, and damping of power system oscillations for high power transfer levels. In this paper the optimal location of a shunt FACT device is investigated for an actual line model of a transmission line having series compensation at the center. Effect of change in degree of series compensation on th...

in our present paper, we present the effectiveness of the controller's electrical power f low Universal (unif ied power f low controller UPFC) w ith the choice of a control strategy. To evaluate the performance and robustness of the system, w e proposed a hybrid control combining the concept of neural networks with conventional regulators vis-à-vis the changes in characteristics of the transmis...

we present a detailed analysis of the static tuning characteristics of three section tunable distributed bragg reflector (dbr) laser. the analysis is based on the transfer matrix method (tmm), transmission line and scattering theory. the key feature of the analysis is the use of modified oscillation condition. with the exact oscillation condition, the static tuning characteristics such as thres...

Time domain reflectometry (TDR) is a measurement technique based upon transmission line theory. The solutions of transmission line equations are reformulated in terms of independent physical properties, instead of coupled per-unit-length circuit parameters. The complete TDR response is effectively modeled by a non-uniform transmission line using the non-recursive ABCD matrix approach. Approache...

In this paper we consider two different approaches for statistical power line channel modeling. The first method follows a top-down approach where the channel transfer function is obtained from an analytical expression whose parameters are drawn from certain statistics. The second method is less conventional and follows a bottom-up approach where the transfer function is computed using transmis...

in this paper, shielding effectiveness (se) of a perforated enclosure with imperfectly conducting walls is evaluated. to this end, first, an accurate numerical technique based on method of moments (mom) ispresented. in this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. then, the impedance boundary condition on the imperfectly conductin...
