Based on the author s twenty years of experience, this book shows the practicality of modern, conceptually new, wide area voltage control in transmission and distribution smart grids, in detail. Evidence is given of the great advantages of this approach, as well as what can be gained by new control functionalities which modern technologies now available can provide. The distinction between solutions of wide area voltage regulation (V-WAR) and wide area voltage protection (V-WAP) are presented, demonstrating the proper synergy between them when they operate on the same power system as well...

This handbook offers the whole knowledge of high voltage substations from their design and construction to the maintenance and the ongoing management, the entire asset life-cycle. The content of the book covers a range of substation topologies: Air-Insulated, Gas-Insulated and Mixed Technology Switchgear Substations together with the essential secondary systems. Additionally specialized substations such as ultra high voltage (UHV), offshore substations for wind power plants and the use of gas insulated lines are included.

The book includes topics, providing information for increased...

Coordinate measuring machines (CMMs) have been conventionally used in industry for 3-dimensional and form-error measurements of macro parts for many years. Ever since the first CMM, developed by Ferranti Co. in the late 1950s, they have been regarded as versatile measuring equipment, yet many CMMs on the market still have inherent systematic errors due to the violation of the Abbe Principle in its design. Current CMMs are only suitable for part tolerance above 10 μm. With the rapid advent of ultraprecision technology, multi-axis machining, and micro/nanotechnology over the past twenty...

This course approaches PLC training from a generic viewpoint. Most PLC platforms have many things in common; before beginning the study of a particular brand of PLC, it is important to learn the things that are common to all platforms. This book does this, pointing out some of the exceptions and different ways of doing things along the way. Resources used in the preparation of this course include information from many of the major PLC manufacturers. Software examples are primarily drawn from Allen-Bradley RSLogix5000 and Siemens Step 7.

The use of plastics in agriculture - to increase crop output, improve food quality and improve sustainability - has grown substantially in both quantity and the range of applications. Many of the early researchers that conducted field research in the use of plastics in agriculture have either retired or are deceased. These early pioneers in plasticulture research, the basis of plant production using plastics, were very creative and persistent in discovering uses of plastics in agricultural applications.

A Guide to the Manufacture, Performance, and Potential of Plastics in...

This book is for all those who are looking for a non-conventional mathematical model of electrical network systems. It presents a modern approach using linear algebra and derives various commonly unknown quantities and interrelations of network analysis. It also explores some applications of algebraic network model of and solves some examples of previously unsolved network problems in planning and operation of network systems. Complex mathematical aspects are illustrated and described in a way that is understandable for non-mathematicians. Discussing interesting concepts and practically...

Dieses bewahrte Lehrbuch gibt einen fundierten Uberblick uber die wichtigsten Maschinenelemente. Der Leser lernt, die Funktionsweise moderner Maschinenteile zu verstehen, sie auszulegen und sicher anzuwenden. Das Buch enthalt die aktuellen Berechnungsverfahren; es ist auf das Wesentliche konzentriert, gleichzeitig aber anwendungs- und praxisorientiert. Die 18. Auflage wurde vollstandig uberarbeitet. Die bewahrte Gliederung wurde beibehalten, der Inhalt jedoch sprachlich und technisch auf den neuesten Stand gebracht. So wurden neben der Umstellung auf die neue Rechtschreibung alle Normen...

Electron Spin Resonance in Food Science covers, in detail, the ESR identification of the irradiation history of food products and beverages to investigate changes that occur during storage, with an aim of improving hygienic quality and extending shelf-life with minimal tempering in nutritional profile.

The book also includes ESR studies on the interaction of food items and packaging materials, along with a section on new approaches in ESR identification of irradiated foods that is followed by a chapter on international legislation relevant to irradiated food.

Christoph Junginger zeigt, dass das etablierte, uber hundert Jahre alte, analytische Berechnungsverfahren zur Bestimmung der Stromverdrangung mit seiner Annahme eines reinen Nutquerfeldes fur hoch ausgenutzte elektrische Maschinen mit flachen Massivleitern nicht ausreicht. Der Autor legt dar, dass es durch zusatzliche Effekte zu einer signifikanten Beeinflussung der resultierenden Stromverdrangung kommen kann. Mit der magnetischen Sattigung, der nebeneinanderliegenden Anordnung von zwei zu verschiedenen Strangen gehorenden Spulenseiten in einer Nut und der Wechselwirkung mit dem...
