Book Description

Optical Fiber Current and Voltage Sensors is the first book to provide a complete, comprehensive and up to date treatment of the domain of fiber optic and polarimetric sensors, covering fundamental operating principles, characteristics, and construction. Written by one of the most recognised experts in polarimetric sensing, Optical Fiber Current and Voltage Sensors begins by covering the fundamentals of polarized light, as well as essential sensor components. The author then goes on to outline various sensor types and their applications, with a focus on sensors for electric phenomena. The chapters then lay out the demands that sensors need to meet, the technical obstacles and limitations which need to be considered. The book also covers comparisons to corresponding traditional instruments, as well as covering alternative non-conventional sensors. This book will be of interest to a broad audience of prospective readers ranging from graduate research students, to researchers in physics and engineering fields, to industry professionals active in the field who wish to learn about the technology and/or are interested in the development of new commercial solutions based on polarimetric-type fiber sensing as well as their use for high voltage current and voltage sensing.

Book Description

This book offers a vision of the future of electricity supply systems and CIGRE’s views on the know-how that will be needed to manage the transition toward them. A variety of factors are driving a transition of electricity supply systems to new supply models, in particular the increasing use of renewable sources, environmental factors and developments in ICT technologies. These factors suggest that there are two possible models for power network development, and that those models are not necessarily exclusive: 1. An increasing importance of large networks for bulk transmission capable of interconnecting load regions and large centralized renewable generation resources, including offshore and of providing more interconnections between the various countries and energy markets. 2. An emergence of clusters of small, largely self-contained distribution networks, which include decentralized local generation, energy storage and active customer participation, intelligently managed so that they operate as active networks providing local active and reactive support. The electricity supply systems of the future will likely include a combination of the above two models, since additional bulk connections and active distribution networks are needed in order to reach ambitious environmental, economic and security-reliability targets. This concise yet comprehensive reference resource on technological developments for future electrical systems has been written and reviewed by experts and the Chairs of the sixteen Study Committees that form the Technical Council of CIGRE.

Book Description

Automatic Control in Power Generation, Distribution, and Protection covers the proceedings of the IFAC Symposium, held in Pretoria, Republic of South Africa on September 15-19, 1980. The book focuses on the methodologies, technologies, processes, and approaches involved in the adoption of automatic control in power generation, distribution, and protection. The selection first elaborates on decentralized and centralized automatic generation control; digital control methods for power station plants based on identified process models; and power generating unit mechanical and electrical system interaction during power system operating disturbances. The text then ponders on modern trends in power system protection; control of power generation and system control with emphasis on modern control theory; and electronics in future power systems. The manuscript takes a look at a specification for an operator load flow program in an energy management system; minimum MVAR generation as an effective criterion for reactive power dispatching; and influence of inaccurate input data on optimal short-term operation of power generation systems. The secondary voltage control of EDF network, directional protection for digital processor use, and securing high availability of protection relays and systems are also discussed. The selection is a dependable reference for readers interested in the application of automatic control in power generation, distribution, and protection.

Book Description

A multidisciplinary reference of engineering measurement tools, techniques, and applications "When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science." — Lord Kelvin Measurement is at the heart of any engineering and scientific discipline and job function. Whether engineers and scientists are attempting to state requirements quantitatively and demonstrate compliance; to track progress and predict results; or to analyze costs and benefits, they must use the right tools and techniques to produce meaningful data. The Handbook of Measurement in Science and Engineering is the most comprehensive, up-to-date reference set on engineering and scientific measurements—beyond anything on the market today. Encyclopedic in scope, Volume 3 covers measurements in physics, electrical engineering and chemistry: Laser Measurement Techniques Magnetic Force Images using Capacitive Coupling Effect Scanning Tunneling Microscopy Measurement of Light and Color The Detection and Measurement of Ionizing Radiation Measuring Time and Comparing Clocks Laboratory-Based Gravity Measurement Cryogenic Measurements Temperature-Dependent Fluorescence Measurements Voltage and Current Transducers for Power Systems Electric Power and Energy Measurement Chemometrics for the Engineering and Measurement Sciences Liquid Chromatography Mass Spectroscopy Measurements of Nitrotyrosine-Containing Proteins Fluorescence Spectroscopy X-Ray Absorption Spectroscopy Nuclear Magnetic Resonance (NMR) Spectroscopy Near Infrared (NIR) Spectroscopy Nanomaterials Properties Chemical Sensing Vital for engineers, scientists, and technical managers in industry and government, Handbook of Measurement in Science and Engineering will also prove ideal for academics and researchers at universities and laboratories.

Book Description

Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment. Following the successful first edition, this second edition of Power System Harmonics maintains the practical approach to the subject and discusses the impact of advanced power electronic technology on instrumentation, simulation, standards and active harmonic elimination techniques. Features include: A new chapter on modern digital instrumentation techniques. Added sections on active filters and modern distorting devices such as FACTS devices, multilevel conversion, current source, voltage source inverters and turn-OFF-related power electronic devices. References to international standards for harmonics and inter-harmonics. Numerical examples of technique application. Offering a comprehensive understanding of power systems, this book is an asset to power engineers involved in the planning, design and operation of power system generation, transmission and distribution. Researchers and postgraduate students in the field will also benefit from this useful reference.
