Pagination - ISBN de l'édition imprimée de référence : 0412562707Langues : Anglais (eng) Mots-clés : Telecommunications engineering signal channels analogue cpmmunications high frequence transmission lines antennasmicrowave telephony television packer swiched satellite Index. décimale : 621.38 Résumé : Telecommunication engineering is concerned with the transmission of in- formation between two distant points. Intuitively we may say that a signal contains information if it teils us something we did not already know. This definition is too imprecise for telecommunications studies, and we shall devote a section oftbis chapter to a formal description ofinformation. For the present it is sufficient to say that a signal that contains information varies in an unpredictable or random manner. We have thus specified a primary characteristic of the signals in telecommunications systems; they are random in nature. These random signals can be broadly subdivided into discrete signals that have a fixed number of possible values, and continuous signals that have any value between given Iimits. Whichever type of signal we deal with, the tele- communication system that it uses can be represented by the generalized model of Fig. 1. 1. The centrat feature of this model is the transmission medium or channel. Some examples of channels are coaxial cables, radio links, optical fibres and ultrasonic transmission through solids and liquids. It is clear from these examples that the characteristics of channels can vary widely. The common feature of all channels, however, is that they modify or distort the waveform of the transmitted signal. In some cases the distortion can be so severe that the signal becomes totally unrecognizable. In many instances it is possible to minimize distortion by careful choice of the transmitted signal waveform.sommaire:signals and channels-analogue modulation theory-discrete signals-noise in analogue communications systems-noise in digital communications systems-high-frequency transmission lines Telecommunications engineering [texte imprimé] / J.

Nombre de pages de l'édition imprimée : 306 pagesLangues : Français (fre) Mots-clés : Smart grid communication technologies channels information security sensing measurement control automation technology management system transmossion power electronic energy storage Index. décimale : 621.38 Résumé : Electric power systems worldwide face radical transformation with the need to decarbonise electricity supply, replace ageing assets and harness new information and communication technologies (ICT). The Smart Grid uses advanced ICT to control next generation power systems reliably and efficiently. This authoritative guide demonstrates the importance of the Smart Grid and shows how ICT will extend beyond transmission voltages to distribution networks and customer–level operation through Smart Meters and Smart Homes.
Smart Grid Technology and Applications:
Clearly unravels the evolving Smart Grid concept with extensive illustrations and practical examples.
Describes the spectrum of key enabling technologies required for the realisation of the Smart Grid with worked examples to illustrate the applications.
Enables readers to engage with the immediate development of the power system and take part in the debate over the future Smart Grid.
Introduces the constituent topics from first principles, assuming only a basic knowledge of mathematics, circuits and power systems.
Brings together the expertise of a highly experienced and international author team from the UK, Sri Lanka, China and Japan.
Electrical, electronics and computer engineering researchers, practitioners and consultants working in inter–disciplinary Smart Grid RD&D will significantly enhance their knowledge through this reference. The tutorial style will greatly benefit final year undergraduate and master s students as the curriculum increasing focuses on the breadth of technologies that contribute to Smart Grid realisation.In Wiley online library Titre de l'écran-titre (visionné le 31 juillet 2012) .sommaire:the smart grid-information and communication technologies-data communication-communication technologies for the smart grid-information security for the smart grid-information security for the smart grid-sensing,measurement,control and automation technologies-distrubution automation equipment-distribution management systems-transmission system operation-power electronics and energy storage-power electronic converters-power electronics in the smart grid-power electronics for bulk power flows-energy storageNote de contenu : In Wiley online library Titre de l'écran-titre (visionné le 31 juillet 2012) -index Smart grid : technology and applications [texte imprimé] / J.
