The wind is a renewable energy resource that can never be exhausted and which avoids pollution. This makes it one of the most environmentally sound energy options available.;Applied to water pumping, the wind has been central in the stimulation of many rural economies, such as the Great Plains in the United States, the Australian outback, and Argentina, and there is still great potential for future development of the wind-pumping resource. However, the scarcity of appropriate information on the technology, economics and potential has restricted dissemination in the developing world. "Windpumping: A Guide for Development Workers" overcomes this problem by taking the reader through every aspect of this topic in a systematic way.;The appendix includes a list of international suppliers and manufacturers of windpumping equipment, together with a summary of their products and services.

The simulation of electromagnetic transients is a mature field that plays an important role in the design of modern power systems. Since the first steps in this field to date, a significant effort has been dedicated to the development of new techniques and more powerful software tools. Sophisticated models, complex solution techniques and powerful simulation tools have been developed to perform studies that are of supreme importance in the design of modern power systems. The first developments of transients tools were mostly aimed at calculating over-voltages. Presently, these tools are applied to a myriad of studies (e.g. FACTS and Custom Power applications, protective relay performance, simulation of smart grids) for which detailed models and fast solution methods can be of paramount importance. This book provides a basic understanding of the main aspects to be considered when performing electromagnetic transients studies, detailing the main applications of present electromagnetic transients (EMT) tools, and discusses new developments for enhanced simulation capability. Key features: * Provides up-to-date information on solution techniques and software capabilities for simulation of electromagnetic transients. * Covers key aspects that can expand the capabilities of a transient software tool (e.g. interfacing techniques) or speed up transients simulation (e.g. dynamic model averaging). * Applies EMT-type tools to a wide spectrum of studies that range from fast electromagnetic transients to slow electromechanical transients, including power electronic applications, distributed energy resources and protection systems. * Illustrates the application of EMT tools to the analysis and simulation of smart grids.

Electricity is highly desired by low-income households, but is all too often only obtained by the richer people in developing countries. The tremendous sacrifices and high payments that low-income households are often prepared to make to obtain even small amounts indicate the importance that they attach to electricity. Low-cost Electrification looks at why, in most developing countries, efforts to provide electricity to poor households have had only limited success, and recommends some appropriate solutions. This Working Paper draws on the experience of experts involved in low-cost electrification and evidence collected from six developing countries. It presents a complete review of the problems faced by poor users which include high connection costs, high costs of house wiring, and houses failing to meet standard requirements; as well as a review of the constraints faced by power utilities such as high capital costs and high revenue-collection costs. The paper suggests a number of new and practical approaches, and ways to implement them, which can make electrification more economic for the utility, and spread the benefits of electrification more equitably across the social spectrum.

The advance of variable speed drives systems (VSDs) engineering highlights the need of specific technical guidance provision by electrical machines and drives manufacturers, so that such applications can be properly designed to present advantages in terms of both energy efficiency and expenditure. This book presents problems and solutions related to inverter-fed electrical motors. Practically orientated, the book describes the reasons, theory and analysis of those problems. Various solutions for individual problems are presented together with the complete design process, modelling and simulation examples with MATLAB/Simulink on the companion website. A key focus of Variable Speed AC Drives with Inverter Output Filters is to examine the state variables estimation and motor control structures which have to be modified according to the used solution (filter). In most control systems the structure and parameters are taken into account to make it possible for precise control of the motor. This methodology is able to include modifications and extensions depending on specific control and estimation structures. Highly accessible, this is an invaluable resource for practising R&D engineers in drive companies, power electronics & control engineers and manufacturers of electrical drives. Senior undergraduate and postgraduate students in electronics and control engineering will also find it of value.
