With an increasing demand for distributing accurate time, preferably accessible in real time, better techniques for time transfer is needed. The inevitable variations in the time transfer delay must be detected and compensated for, if an absolute precision better than μs-level is needed, for transmission distance exceeding a few km. This is usually solved through two-way transfer, where the tra...

This paper proposes an optimal transmission expansion planning (TEP) which is based on determining share of each line in merchandizing surplus (MS) of system, determining by Independent System Operator (ISO). The more share of a line in MS of system denotes the priority of a line for expansion. The procedure of determining MS of each line in a power system is based on determining the MS share o...

In the present paper, the problem of externally excited exponential transmission line hasbeen solved analytically in frequency domain using a simple approach. Then steplines approximationas a first order approximation for the problem of externally excited nonuniform transmission lines ingeneral and exponentially tapered transmission line (ETL) as a special case has been presented.Finally the tw...

Series-compensated transmission lines can lead to a sub-synchronous resonance (SSR) phenomenon at high compensation levels, where the system lacks stability. Gate-controlled series capacitor (GCSC) is widely used damp SSR. Here, an effective and new methodology for damping SSR presented. The proposed method aims alleviate based on estimating both frequency maximum value of voltage magnitude sig...

We analytically study the shock wave in Josephson transmission line (JTL) presence of ohmic dissipation. When resistors shunt junctions (JJ) or are introduced series with ground capacitors, is broadened. JJ, remains sharp, as it was absence In all cases considered, do not influence propagation velocity. an alternative to wave—an expansion fan—in framework simple approximation for dissipationles...
