Major changes have occurred in both the composition of energy supply and the choice of technology, especially in activities in which energy intensity has a significant bearing on the costs and competitiveness of goods and services. Presented here, in the context of these changes, are case studies on the macroeconomic evaluation of ethylalcohol programs and the microeconomic evaluation of technologies for irrigation pumping. "Environment and Resource Conservation" During the last decade, a large volume of literature has addressed the two major policy issues concerning energy programs in developing countries: overall energy conservation and provision of energy for rural development needs. Yet, many of these works have been supply-sided without adequate analysis of users' needs and the different option to meet them. Ex-post evaluations of existing field experiences with renewable technologies are still scarce, and many of those which have appeared provide limited insights for planning and implementation in different countries. Socioeconomic Aspects of Renewable Energy Technologies addresses these oversights. A selected number of technologies and topics concerning renewable energy sources for developing countries are discussed, including ethanol and the macro-economic evaluation of ethanol programs; various renewable energy technologies for end-use such was water-pumping for irrigation; and the micro-economic evaluation of these additional technologies.
Computational Electromagnetics is a young and growing discipline, expanding as a result of the steadily increasing demand for software for the design and analysis of electrical devices. This book introduces three of the most popular numerical methods for simulating electromagnetic fields: the finite difference method, the finite element method and the method of moments. In particular it focuses on how these methods are used to obtain valid approximations to the solutions of Maxwell's equations, using, for example, "staggered grids" and "edge elements." The main goal of the book is to make the reader aware of different sources of errors in numerical computations, and also to provide the tools for assessing the accuracy of numerical methods and their solutions. To reach this goal, convergence analysis, extrapolation, von Neumann stability analysis, and dispersion analysis are introduced and used frequently throughout the book. Another major goal of the book is to provide students with enough practical understanding of the methods so they are able to write simple programs on their own. To achieve this, the book contains several MATLAB programs and detailed description of practical issues such as assembly of finite element matrices and handling of unstructured meshes. Finally, the book aims at making the students well-aware of the strengths and weaknesses of the different methods, so they can decide which method is best for each problem. In thissecond edition, extensive computer projects are added as well as new material throughout. Reviews of previous edition: "The well-written monograph is devoted to students at the undergraduate level, but is also useful for practising engineers." (Zentralblatt MATH, 2007)"

The protection which is installed on an industrial power system is likely to be subjected to more difficult conditions than the protection on any other kind of power system. Starting with the many simple devices which are employed and covering the whole area of industrial power system protection, this book aims to help achieve a thorough understanding of the protection necessary. Vital aspects such as the modern cartridge fuse, types of
relays, and the role of the current transformer are covered and the
widely used inverse definite-minimum time overcurrent relay, the
theory of the Merz-Price protection system and the development of
the high-impedance relay system are critically examined. This new
edition has come about in response to the dramatic change from the
use of electro-magnetic relays to electronic and micro-processor
relays which figure in practically all new installations.
Therefore, although the theory and usage are the same, the
application can be much improved owing to the increased range and
accuracy and the added facilities provided with the modern relays.
This book reflects the change and explains the technical
advantages.
Fault-tolerance in integrated circuits is not an exclusive concern regarding space designers or highly-reliable application engineers. Rather, designers of next generation products must cope with reduced margin noises due to technological advances. The continuous evolution of the fabrication technology process of semiconductor components, in terms of transistor geometry shrinking, power supply, speed, and logic density, has significantly reduced the reliability of very deep submicron integrated circuits, in face of the various internal and external sources of noise. The very popular Field Programmable Gate Arrays, customizable by SRAM cells, are a consequence of the integrated circuit evolution with millions of memory cells to implement the logic, embedded memories, routing, and more recently with embedded microprocessors cores. These re-programmable systems-on-chip platforms must be fault-tolerant to cope with present days requirements. This book discusses fault-tolerance techniques for SRAM-based Field Programmable Gate Arrays (FPGAs). It starts by showing the model of the problem and the upset effects in the programmable architecture. to protect integrated circuits against errors. A large set of methods for designing fault tolerance systems in SRAM-based FPGAs is described. Some presented techniques are based on developing a new fault-tolerant architecture with new robustness FPGA elements. Other techniques are based on protecting the high-level hardware description before the synthesis in the FPGA. The reader has the flexibility of choosing the most suitable fault-tolerance technique for its project and to compare a set of fault tolerant techniques for programmable logic applications.

This book investigates the utilization of harmonics in the permanent magnet (PM) or rotor shape to improve the torque density of PM brushless AC machines including three-phase inner rotor and outer rotor machines, five-phase machines, dual three-phase machines, linear machines, by means of analytical, finite element analyses, and as well as experimental validation. The torque density can be improved while the torque ripple remains low in PM shaping utilizing the 3rd harmonic. In this book, the analytical expression of output torque is derived for PM machines with rotor shape using the 3rd harmonic, and then the optimal 3rd harmonic for maximizing torque is analytically obtained. The book compares the PM shape in surface-mounted PM (SPM) machines and the rotor lamination shape in interior PM (IPM) machines utilizing the 3rd harmonic, and it becomes clear that their shaping methods and amount of torque improvement are different. In a five-phase PM machine, the 3rd harmonic can be utilized in both the current waveform and PM shapes to further improve the output torque. For the dual three-phase SPM machines without deteriorating the torque more than 30% when the optimal 3rd harmonic into both the current and PM shape are injected. The harmonics in airgap flux density have significant influence on the cogging torque, stator iron flux distribution, and radial force between the rotor and stator. These effects has been investigated as well in this book.

This book focuses on the introduction of new and modern maintenance management frameworks of assets in the electricity & gas network sector and more specifically, on electricity networks for distribution. The author describes methodologies for developing and implementing maintenance management maturity models, using case studies to show how these have been applied. These maturity models are discussed as part of an overarching, multi-disciplinary organizational maintenance management professionalization framework. This book adds a new dimension to the well-known Reliability Centered Maintenance (RCM) method, by incorporating failure modes via multiple scenarios into business values, by means of statistical risk calculation methods. The author demonstrates a method called Utility Risk Linked RCM, which uses a statistical tool to develop failure models which can be used to predict future failure behavior of assets in relation to corporate business values. This new method is a practical, structured and comprehensive framework for assessing risk based maintenance policies. The book also proposes a condition monitoring framework that can be used as a guide to assist asset managers in identifying the relationship between failure modes, ageing processes to select amongst condition monitoring regimes.

Power Generation from Solid Fuels introduces the different technologies to produce heat and power from solid fossil (hard coal, brown coal) and renewable (biomass, waste) fuels, such as combustion and gasification, steam power plants and combined cycles etc. The book discusses technologies with regard to their efficiency, emissions, operational behavior, residues and costs. Besides proven state of the art processes, the focus is on the potential of new technologies currently under development or demonstration. The main motivation of the book is to explain the technical possibilities for reducing CO2 emissions from solid fuels. The strategies which are treated are: more efficient power and heat generation technologies, processes for the utilisation of renewable solid fuels, such as biomass and waste, and technologies for carbon capture and storage. Power Generation from Solid Fuels provides, both to academia and industry, a concise treatment of industrial combustion of all types of solid, hopefully inspiring the next generation of engineers and scientists.
The re-engineering of power transmission systems is crucial to meeting the objectives of such regulators as the European Union. In addition to its market, organisational and regulatory aspects, this re-engineering will also involve technical issues dealing with the progressive integration of innovative transmission technologies in the daily operation of transmission system operators. In this context, Advanced Technologies for Future Transmission Grids provides an overview of the most promising technologies, likely to be of help to planners of transmission grids in responding to the challenges of the future: security of supply; integration of renewable generation; and creation of integrated energy markets (using the European case as an example). These issues have increased importance because of administrative complication and the fragmentation of public opinion expressed on the build up of new infrastructure. For each technology discussed, the focus is on the technical-economic perspective rather than on purely technological points of view. A transmission-system-operator-targeted Technology Roadmap is presented for the integration of promising innovative power transmission technologies within power systems of the mid-long term. Although the primary focus of this text is in the sphere of the European energy market, the lessons learned can be generalized to the energy markets of other regions. |
