The inverse-time characteristics of overcurrent relays are defined in this standard. Operating equations and allowances are provided in the standard. The standard defines an integral equation for microprocessor relays that ensures coordination not only in the case of constant current input but for any current condition of varying magnitude. Electromechanical inverse-time overcurrent relay reset characteristics are defined in the event that designers of microprocessor based relays and computer relays want to match the reset characteristics of the electromechanical relays.

Die rationelle Energieverwendung im Bereich wärmetechnischer Systeme hat im mittel europäischen Raum einen hohen Stellenwert, da bei der überwiegenden Anzahl der Haus halte und Gewerbebetriebe der Energieverbrauch zur Wärmeerzeugung den größten An teil am Gesamtenergieverbrauch hat. Das Ziel des vorliegenden Bandes ist es, dem Leser die Vorgehensweise 'zur Beurteilung wärmetechnischer Systeme und energiesparender Maßnahmen zu vermitteln. Schwerpunktmäßig werden die Heiz- und Raumlufttechnik im Umfeld des Menschen behandelt, während das Gebiet der Prozeßwärme für die indu strielle Anwendung aus Gründen des Umfanges nur ansatzweise erörtert werden konnte. Der Anspruch dieses Buches liegt auf einer Ebene, welche bewußt nicht die Einzellösung hervorhebt, da sich das Optimum eines Gesamtsystems noch längst nicht einstellen muß, wenn die Teilsysteme optimiert sind. Das Verständnis der Verzahntheit des vorliegenden Gebietes mit anderen Fachgebieten ist deshalb eine wesentliche Voraussetzung für ko ordinierte Maßnahmen zur rationellen Energieverwendung. Diesem Umstand wird durch zahlreiche qualitative Systembetrachtungen und Zahlenbeispiele Rechnung getragen. Im ersten Abschnitt werden die speziellen Grundlagen der Heiz- und Raumlufttechnik be handelt. Dazu zählen Kenntnisse über technische Funktionsabläufe und die Behaglich keitsanforderungen des Menschen, zu deren Aufrechterhaltung diese Anlagen gebaut werden. Anlagentechnische Maßnahmen zur Energieeinsparung müssen sich immer an der Erfüllung der Behaglichkeitsanforderungen messen lassen. Weiterhin gehört es auch zu einer wirkungsvollen Energieberatung, Maßnahmen an gebäudetechnischen Anlagen als Teilmaßnahme am Gesamtsystem Gebäude zu verstehen, weil durch den Umfang der Systemverbesserung (energetisch-ökonomisch) letztlich die Rangfolge der durchzuführen den Maßnahmen bestimmt wird.

This highly experienced author sets out to build a bridge between two inter-disciplinary power engineering practices. The book looks into two major fields used in modern power systems: intelligent systems and the signal processing. The intelligent systems section comprises fuzzy logic, neural network and support vector machine. The author looks at relevant theories on the topics without assuming much particular background. Following the theoretical basics, he studies their applications in various problems in power engineering, like, load forecasting, phase balancing, or disturbance analysis.

Power outages have considerable social and economic impacts, and effective protection schemes are crucial to avoiding them. While most textbooks focus on the transmission and distribution aspects of protective relays, Protective Relaying for Power Generation Systems is the first to focus on protection of motors and generators from a power generation perspective. It also includes workbook constructions that allow students to perform protection-related calculations in Mathcad® and Excel®. This text provides both a general overview and in-depth discussion of each topic, making it easy to tailor the material to students' needs. It also covers topics not found in other texts on the subject, including detailed time decrement generator fault calculations and minimum excitation limit. The author clearly explains the potential for damage and damaging mechanisms related to each protection function and includes thorough derivations of complex system interactions. Such derivations underlie the various rule-of-thumb setting criteria, provide insight into why the rules-of-thumb work and when they are not appropriate, and are useful for post-incident analysis. The book's flexible approach combines theoretical discussions with example settings that offer quick how-to information. Protective Relaying for Power Generation Systems integrates fundamental knowledge with practical tools to ensure students have a thorough understanding of protection schemes and issues that arise during or after abnormal operation.

More than 75 case studies are presented, shedding light on design and relay setting calculations for the protection and control of power system elements. Logically organized, Protection and Control for Power Systems begins with an introduction to power system relaying functions and their implementation. Moving on, it deals with system faults, relay transducers, relay DC tripping circuits, and system grounding. Subsequent chapters discuss protection and control systems for transformers, generators, lines and cables, buses, breakers, distribution systems, phase angle regulating transformers, shunt capacitors and shunt reactors. Drawing on the author's half century of experience, the text enables engineers and other readers to utilize techniques and calculations in the application of protection and control for power system. It documents material published for the first time covering the philosophy of setting ground time over-current protection for transmission lines, supported by actual power system case studies. Additionally, protection of phase angle regulating transformers is covered in detail using real world numerical relaying applications. The book presents power system protection and control details, how they are applied, set and designed for most power system elements. Topics like symmetrical components, fault calculations, relay input devices, relay design and relay setting calculations are fully addressed. It further outlines the basics of protection and control for power system elements utilizing actual system case studies involving the protection system methods. This use of case studies and problems provides insights into protection and control engineering not usually presented in a single text. The emphasis on relay system design application and relay settings calculations are a central theme. Aimed at students, the book is ideal for undergraduate and graduate students seeking to sharpen and enhance their power system protection and control background. It conveys the basic principles of system protection and control and includes more than 90 problems to reinforce these principles. For these reasons, Protection and Control for Power Systems can greatly benefit students and young engineers who require a better understanding of the basics of protection and control engineering. Experienced protection engineers will also find the book beneficial as a solid reference guide.

This book builds on the cutting edge research presented in the previous edition that was the first of its kind to present the technology behind an emerging power systems management tool still in the early stages of commercial roll-out. In the intervening years, synchrophasors have become a crucial and widely adopted tool in the battle against electricity grid failures around the world. Still the most accurate wide area measurement (WAMS) technology for power systems, synchronized phasor measurements have become increasingly sophisticated and useful for system monitoring, as the advent of big data storage allows for more nuanced real-time analysis, allowing operators to predict, prevent and mitigate the impacts of blackouts with enhanced accuracy and effectiveness. This new edition continues to provide the most encompassing overview of the technology from its pioneers, and has been expanded and updated to include all the applications and optimizations of the last decade.
