Available in PDF, EPUB and Kindle. Book excerpt: Energy is the mainstay of industrial societies, and without an adequate supply of energy the social, political and economic stability of nations is put into jeopardy. With supplies of inexpensive fossil fuels decreasing, and climate change factors becoming more threatening, the need to conserve energy and move steadily to more sustainable energy sources is more urgent than ever before. The updated Second Edition of this successful handbook includes chapters from leading experts on the economics and fiscal management of energy, with a focus on the tools available to advance efficiency and conservation measures. Updated coverage of renewable energy sources, energy storage technologies, energy audits for buildings and building systems, and demand-side management is provided. The appendix of the handbook provides extensive data resources for analysis and calculation.

Download or read book Assessing the Energy Efficiency of Pumps and Pump Units written by em. Dr.-Ing Bernd Stoffel and published by Elsevier. This book was released on 2015-04-10 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assessing the Energy Efficiency of Pumps and Pump Units, developed in cooperation with Europump, is the first book available providing the background, methodology, and assessment tools for understanding and calculating energy efficiency for pumps and extended products (pumps+motors+drives). Responding to new EU requirements for pump efficiency, and US DOE exploratory work in setting pump energy efficiency guidelines, this book provides explanation, derivation, and illustration of PA and EPA methods for assessing energy efficiency. It surveys legislation related to pump energy efficiencies, provides background on pump and motor efficiencies, and describes the concept of Energy Efficiency Index (EEI) for circulators and single and multi-pump systems. The first book to cover Europump- sponsored research on energy efficiency in pumps, including coverage of new EU guidelines implemented in January 2015 Discusses Product Approach (PA) and Extended Product Approach (EPA) to assessing energy efficiency Derives and explains the Minimum Efficiency Index (MEI)

Download or read book Induction Machines Handbook written by Ion Boldea and published by CRC Press. This book was released on 2020-05-26 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Induction Machines Handbook: Steady State Modeling and Performance offers a thorough treatment of steady-state induction machines (IM), the most used electric motor (generator) in rather constant or variable speed drives, forever lower energy consumption and higher productivity in basically all industries, from home appliances, through robotics to e-transport and wind energy conversion. Chapter 1 offers a detailed introduction from fundamental principles to topological classifications and most important applications and power ranges from tens of W to tens of MW. Then individual Chapters 2 and 4 deal in detail with specific issues, such as Magnetic, electric, and insulation materials Electric windings and their mmf Magnetization curve and inductance Leakage inductances and resistances Steady-state equivalent circuit and performance Starting and speed control methods Skin and on-load saturation effects Field harmonics, parasitic torques, radial forces, noise Losses Thermal modeling Single-phase induction machine basics Single-phase induction motors: steady-state modeling and performance Fully revised and updated to reflect the last decade’s progress in the field, this third edition adds new sections, such as Multiphase and multilayer tooth-wound coil windings The brushless doubly fed induction machine (BDFIM) Equivalent circuits for BDFIM Control principles for doubly fed IM Magnetic saturation effects on current and torque versus slip curves Rotor leakage reactance saturation Closed-slot IM saturation The origin of electromagnetic vibration by practical experience PM-assisted split-phase cage-rotor IM’s steady state The promise of renewable (hydro and wind) energy via cage-rotor and doubly fed variable speed generators e-transport propulsion and i-home appliances makes this third edition a state-of-the-art tool, conceived with numerous case studies and timely for both academia and industry.

Download or read book Reluctance Electric Machines written by Ion Boldea and published by CRC Press. This book was released on 2018-07-20 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric energy is arguably a key agent for our material prosperity. With the notable exception of photovoltaic generators, electric generators are exclusively used to produce electric energy from mechanical energy. More than 60% of all electric energy is used in electric motors for useful mechanical work in various industries. This book presents the modeling, performance, design, and control of reluctance synchronous and flux-modulation machines developed for higher efficiency and lower cost. It covers one- and three-phase reluctance synchronous motors in line-start applications and various reluctance flux-modulation motors in pulse width modulation converter-fed variable speed drives. FEATURES Presents basic and up-to-date knowledge about the topologies, modeling, performance, design, and control of reluctance synchronous machines. Includes information on recently introduced reluctance flux-modulation electric machines (switched- flux, flux-reversal, Vernier, transverse flux, claw pole, magnetic-geared dual-rotor, brushless doubly fed, etc.). Features numerous examples and case studies throughout. Provides a comprehensive overview of all reluctance electric machines.
