| relay logic books: Digital Protective Relays Vladimir Gurevich, 2017-12-19 Digital (microprocessor-based) protection relays (DPR) are dominating the global market today, essentially pushing all other types of relays out of the picture. These devices play a vital role in power operations for fields ranging from manufacturing, transportation, and communication to banking and healthcare. Digital Protective Relays: Problems and Solutions offers a unique focus on the problems and disadvantages associated with their use, a crucial aspect that goes largely unexamined. While there is already a massive amount of literature documenting the benefits of using digital relays, devices as sophisticated as DPR obviously have faults and drawbacks that need to be understood. This book covers these, delving into the less familiar inner workings of DPR to fill a critical literary void and help decision makers and specialists in the field of protection relays find their way out of the informational vacuum. The book provides vital information to assist them in evaluating relay producers' claims and then choose the right product. Tearing away the informational curtain that exists today, this book: Describes construction of functional modules of existing relays Analyzes drawbacks and problems of digital relays Details specific technical problems and their solutions Assesses dangers of intentional destructive electromagnetic intrusions Discusses alternative (non-microprocessor-based) protection relays, and problems related to international standards Focusing on practical solutions, this book explains how to correctly choose digital relays and ensure their proper use while avoiding the many problems they can present. The author avoids mathematics and theory in favor of more practical, tangible information not easily found elsewhere. Setting itself apart from other books on the subject, this volume shines a light into the long hidden black box of information |

He uses a show-not-tell approach that employs nearly 1300 illustrations and reveals valuable insight based on his extensive experience in the field. The book begins with the basic principles of relay construction and the major functional parts, such as contact and magnetic systems. Then, it devotes individual chapters to the various types of relays. The author describes the principles of function and construction for each type as well as features of several relays belonging to a type that operate on different principles. Remarkably thorough and uniquely practical, Electric Relays: Principles and Applications serves as the perfect introduction to the plethora of electric relays and offers a quick-reference guide for the experienced engineer. |
| relay logic books: Air Logic Control for Automated Systems Rudy Wojtecki, 1999-06-18 As industrial processes become more and more automated, Air Logic Control (ALC) becomes increasingly important. As the use of ALC becomes more widespread, the need for designers, engineers, and technicians with a working knowledge of ALC technology grows significantly. Air Logic Control for Automated Systems provides the means for anyone involved with control systems to acquire the knowledge and skills they need to implement and maintain ALC for automated manufacturing. The author focuses on the two types of ALC most often encountered: fluidics and Moving Parts Logic (MPL). He provides a thorough background on the subject, including the properties of compressible fluids, the fundamentals of pneumatics, and the fundamentals of logic systems, then delves into both moving parts and non-moving parts concepts and components. He discusses signal transmission, communications, electrical and electronic devices, plus the symbology, schematics, and flow diagrams related to ALC, and offers a complete overview of ALC system design. With this background established, the author presents three case studies of increasing complexity: a press control system, a parts sorting system, and a bottle filling system. These studies each offer a different approach to problem-solving and together they illustrate the alternative methods available in practice. Air Logic Control for Automated Systems thus offers technicians, engineers, and designers the foundation for understanding ALC. Armed with this knowledge, they are equipped to handle any number of implementation, programming, maintenance, and troubleshooting tasks with confidence. |

After introductory chapters related to protection technology and functions, Digital Signal Processing in Power System Protection and Control presents the digital algorithms for signal filtering, followed by measurement algorithms of the most commonly-used protection criteria values and decision-making methods in protective relays. A large part of the book is devoted to the basic theory and applications of artificial intelligence techniques for protection and control. Fuzzy logic based schemes, artificial neural networks, expert systems and genetic algorithms with their advantages and drawbacks are discussed. AI techniques are compared and it is also shown how they can be combined to eliminate the disadvantages and magnify the useful features of particular techniques. The information provided in Digital Signal Processing in Power System Protection and Control can be useful for protection engineers working in utilities at various levels of the electricity network, as well as for students of electrical engineering, especially electrical power engineering. It may also be helpful for other readers who want to get acquainted with and to apply the filtering, measuring and decision-making algorithms for purposes other than protection and control, everywhere fast and on-line signal analysis is needed for proper functioning of the apparatus. |
