Average zonal transmission losses
Power Engineer, 2003In April 2004 average zonal transmission losses (AZTL) charging is due to be introduced in England and Wales. In April 2005, the British Electricity Trading and Transmission Arrangements (BETTA) are due to go-live throughout Great Britain without AZTL. The authors analyse the arguments surrounding the introduction of locational loss charging.

Advances in understanding propagation of ‘‘underwater sound’’ are traced from the view expressed in Urick’s 1967 landmark text to our current state through two remarkable transitions. First, propagation in 1967 was an arcane phenomenon with annoying, questionably modelable ‘‘anomalies’’ from spherical spreading which forced extensive global ...

Fractional Transmission Line with Losses
Zeitschrift für Naturforschung A, 2014Abstract In this manuscript, the fractional transmission line with losses is presented. The order of the Caputo derivative is considered as 0 < β ≤ 1 and 0 < γ ≤ 1 for the fractional equation in space and time domain, respectively. Two cases are solved, with fractional spatial and fractional temporal derivatives, and also numerical

Characterization of Transmission Losses
IEEE Transactions on Power Systems, 2011In this paper, characterizing transmission losses according to their origin is carried out. Transmission loss is decomposed into three components. The first is due to the current flow from generators to loads. The second is due to the circulating current between generators.

Nodal unbundling of transmission losses
2003 IEEE Bologna Power Tech Conference Proceedings,, 2004This paper presents a new methodology to evaluate and charge system losses shares among market participants on a nodal basis. The approach is based on the assumption that all power injections take place simultaneously, giving rise to loss responsibilities on an a posteriori basis.

Troposcatter transmission loss subsectoin model
2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017Caused by atmospheric irregularities, tropospheric scatter is the principal mechanism for radio trans-horizon propagation which occurs permanently at frequencies higher/larger than 30 MHz. The study of Tropospheric scatter propagation characteristics is a hot issue. The transmission loss is a vital factor to describe those characteristics for designing

The transmission of sound through walls and barriers is an extremely important topic for noise control engineers. In this chapter we examine the basic principles of how sound passes through walls. The primary physical characteristics that influence sound transmission through walls are studied, including the importance of mass and how the bending ...

Losses in power transmission networks
Electrical Engineering, 1950THE DETERMINATION of transmission-system losses as a function of generating-station loading is of importance to the engineers responsible for the efficient operation of electric power systems. Those responsible for load dispatching have for the most part operated with a good knowledge of generation costs in each individual station, but have had ...

Minimum-Loss Two-Conductor Transmission Lines
IRE Transactions on Circuit Theory, 1958Of all two-conductor transmission lines in which the harmonic mean of the perimeters of the two conductors is fixed, the one having the lowest loss is a conventional round coaxial line. It is conjectured that the same is true of the class having fixed cross section area.

Loss: transmissions, recognitions, authorisations
2003When someone dies and their belongings are dispersed, those who remember them lose the familiar, home, places in which they habitually met. They had set up unconscious habits and previous times – the chair, the arrangement of table settings, the ashtray and vase on the mantelpiece that would be reminders of the ordinary times together have now gone. An
