this paper proposes a new method for transmission loss allocation. the share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. then, it is applied to the total network transmission lines. in the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introduced...
A new PMU-based fault detection/location algorithm for multi-terminal transmission lines is proposed in this paper, which works on the basis of synchronized voltage and current phasors received from PMUs installed in various terminals. The Clark transform (for transposed transmission lines), Eigen-values and eigenvectors theory (for un-transposed ones) are used to decouple 3-phase differential ...
Examining cables using many conductor transmission line theory has shed light on the modes supported by various cable types. However, so far disregards fundamental surface wave mode whose lateral confinement increases with frequency and hence is expected to play an important role in high applications. To address this issue, we propose extension which incorporates waves uncoated, cylindrical wir...

A theory for the electromagnetic radiation from unbalanced transmission lines is developed. It is shown that radiation results from the convection current that develops in unbalanced transmission lines where the resistances of the lines are unequal. The process that leads to the generation of the nonlinear convection current in unbalanced transmission lines is explained. It is proved that the c...
there are some problems with estimating the time required for the manufacturing process of products, especially when there is a variable serving time, like control stage. these problems will cause overestimation of process time. layout constraints, reworking constraints and inflexible product schedule in multi product lines need a precise planning to reduce volume in particular situation of lin...
