Free Download Power Transmission by Direct Current by Erich Uhlmann English | PDF | 1975 | 397 Pages | ISBN : 3642660746 | 37.5 MB The direct current transmission scheme linking the island of Gotland to the main land of Sweden by means of a submarine cable under the Baltic Sea is the first commercial realisation of a modern technique for the transmission of electrical energy. It is certainly not accidental that this pioneering initiative was allotted to the Gotland scheme. Various viewpoints may be presented regarding this, but the essential factor relates to the circumstances that permitted the magnitude ofthe transmitted power to be given a value which would not have been technically or economically feasible for any other project. The power, on the one hand, was sufficiently small to justify the risk associated with such a new venture, for it fell within limits acceptable both to ASEA as the manufacturer and to the Swedish State Power Board as the customer. On the other hand, the power was large enough to demonstrate the technical and economic characteristics of the new system and to provide the opportunity of gaining invaluable experience that could be applied to future large-scale transmission systems. In 1954 a team under the direction of Dr. Uno Lamm successfully commissioned the Gotland scheme, representing the culmination of many years of intensive development work.  Free Download Power Transmission and Control in Power and Vehicle Machineries by Yunhua Li, Nariman Sepehri English | 2024 | ISBN: 3725824495 | 328 Pages | PDF | 31 MB  Free Download Faouzi Derbel, "Power Systems & Smart Energies " English | ISBN: 3110591170 | 2020 | 142 pages | PDF | 5 MB The book presents selected, extended and peer reviewed papers from the International Multiconference on System, Automation and Control held Leipzig in 2016. These are complemented with solicited contributions by international experts. This volume is devoted to power electronics in renewable energy systems as well as to hybrid renewable energy systems.  Free Download Power System Dynamics and Stability by Da Xie, Yanchi Zhang English | 2024 | ISBN: 3725821631 | 288 Pages | PDF | 32 MB  Free Download Power System Dynamic Modelling and Analysis in Evolving Networks by Babak Badrzadeh, Zia Emin English | EPUB (True) | 2024 | 893 Pages | ISBN : 3031478207 | 160.2 MB This Green Book is an essential resource for power system engineers seeking comprehensive information on contemporary power system dynamic modelling and analysis. With today's rapid adoption of inverter-based resources and the resulting changes in power system dynamics, this book compares conventional power systems with evolving power systems characterized by high shares of grid-connected and distributed inverter-based resources. It covers dynamic phenomena, analysis methods, simulation tools and enablers required for secure and reliable system planning and operation.  Free Download Power Quality Enhancement Using Custom Power Devices by Arindam Ghosh , Gerard Ledwich English | PDF (True) | 2002 | 474 Pages | ISBN : 1402071809 | 36.6 MB Also addressed are other power electronic devices for improving power quality in Solid State Transfer Switches and Fault Current Limiters. Applications for these technologies as they relate to compensating busses supplied by a weak line and for distributed generation connections in rural networks, are included. In depth treatment of inverters to achieve voltage support, voltage balancing, harmonic suppression and transient suppression in realistic network environments are also covered. New material on the potential for shunt and series compensation which emphasizes the importance of control design has been introduced.  Free Download Power Management of Digital Circuits in Deep Sub-Micron CMOS Technologies by Stephan Henzler English | PDF (True) | 2007 | 197 Pages | ISBN : 1402050801 | 4.5 MB In the deep sub-micron regime, the power consumption has become one of the most important issues for competitive design of digital circuits. Due to dramatically increasing leakage currents, the power consumption does not take advantage of technology scaling as before. State-of-art power reduction techniques like the use of multiple supply and threshold voltages, transistor stack forcing and power gating are discussed with respect to implementation and power saving capability. Focus is given especially on technology dependencies, process variations and technology scaling. Design and implementation issues are discussed with respect to the trade-off between power reduction, performance degradation, and system level constraints. A complete top-down design flow is demonstrated for power gating techniques introducing new design methodologies for the switch sizing task and circuit blocks for data-retention and block activation. The leakage reduction ratio and the minimum power-down time are introduced as figures of merit to describe the power gating technique on system level and give a relation to physical circuit parameters. Power Management of Digital Circuits in Deep Sub-Micron CMOS Technologies mainly deals with circuit design but also addresses the interface between circuit and system level design on the one side and between circuit and physical design on the other side.  Free Download Power: Entailment, status, and social mobility (14th-17th centuries) by Ana Rita Rocha English | 2024 | ISBN: 9789892626659 | 364 Pages | PDF | 2.9 MB  Free Download Power Electronics and Actuators by Dong Jiang English | 2024 | ISBN: 372582861X | 318 Pages | PDF | 49 MB  Free Download Postmodernism and the Ethics of Theological Knowledge (Routledge New Critical Thinking in Religion, Theology and Biblical Studies) By Justin Thacker 2007 | 154 Pages | ISBN: 0754661857 | PDF | 1 MB This book establishes the necessary integration of theological knowledge with theological ethics. It does this as a response to the postmodern critique of Christianity, as exemplified in Rorty and Lyotard. They argue that any claim to know God is necessarily tyrannical. Contemporary responses to such postmodern thinking often fail to address adequately the ethical critique that is made. This book redresses that balance by suggesting that our knowedge of God and love of the Other are so intimately connected that we cannot have one without the other. In the absence of love, then, we simply do not know God. Justin Thacker proposes that an effective theological response to postmodernity must address both knowledge and ethics in an integrated fashion as presented in this book. |
