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:
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 on DPRs, giving users a valuable tool to help them anticipate possible problems, something sorely lacking in the literature.

The book has been updated to remove complex and abstract technical thought and replace it with practical information that will be essential for students and general readers alike. It builds on basic principles such as simple circuits and switches, going on to explain how basic components can be used to form versatile digital systems, which can be combined and programmed to create new functional systems. It also covers microprocessor technology and microcontroller chips, showing how to program microcontrollers for learners wishing to explore this new technology.
Practical Electronics employs the 'Breakthrough Method' to help you advance quickly at any subject, whether you're studing for an exam or just for your own interst. The Breakthrough Method is designed to overcome typical problems you'll face as learn new concepts and skills.
- Problem: "I find it difficult to remember what I've read."; Solution: this book includes end-of-chapter summaries and questions to test your understanding.
- Problem: "Lots of introductory books turn out to cover totally different topics than my course."; Solution: this book is written by a university lecturer who understands what students are expected to know.
A Guide to Relay Protection Power Supply for Engineers and Technicians
The first chapter reviews the electronics and primary elements of the system, including transistors, thyristors, optocouplers, logic elements, and relays, and their principles of operation. This background gives staff who service relay protection power supply systems the necessary electronics knowledge to help them work more effectively with the equipment. The next chapters of the book then cover built-in digital protection relay power supplies, battery chargers, accumulator batteries, uninterruptible power supply, and characteristic features of auxiliary DC systems at substations and power plants. The final chapters discuss questions and problems that engineers and technicians may face. These include insulation problems, issues in auxiliary DC power supply such as voltage dips, and electromagnetic disturbances such as blackouts, spikes, and surges. The author also explains how to address them.
Suitable for beginners and experienced engineers alike, the book is written for those who work with relay protection systems and with AC and DC auxiliary power systems in power plants and substations. It combines theory and practical recommendations to provide a valuable reference on power supply devices and systems.
Explores developments in the creation of smarter, more flexible protective systems based on advances in the computational power of digital devices and the capabilities of communication systems that can be applied within the power grid Examines the regulations related to power system protection and how they impact the way protective relaying systems are designed, applied, set, and monitored Considers the evaluation of protective systems during system disturbances and describes the tools available for analysis Addresses the benefits and problems associated with applying microprocessor-based devices in protection schemes Contains an expanded discussion of intertie protection requirements at dispersed generation facilities
Providing information on a mixture of old and new equipment, Protective Relaying: Principles and Applications, Fourth Edition reflects the present state of power systems currently in operation, making it a handy reference for practicing protection engineers. And yet its challenging end-of-chapter problems, coverage of the basic mathematical requirements for fault analysis, and real-world examples ensure engineering students receive a practical, effective education on protective systems. Plus, with the inclusion of a solutions manual and figure slides with qualifying course adoption, the Fourth Edition is ready-made for classroom implementation.
Electronic Devices on Discrete Components for Industrial and Power Engineering answers the question above with a resounding “Yes!” by describing ten original automatic devices based exclusively on modern discrete components. The book reveals that devices based on high-voltage transistors and thyristors as well as miniature vacuum and high power gas-filled reed switches are actually much simpler to implement and more reliable than traditional devices. By identifying elementary functional modules and the basic working principles of semi-conductor devices, the text allows for the construction of complete automatic devices. It also contains an extensive reference section that includes information on modern high-voltage bipolar, FET and IGBT transistors, thyristors and triacs, as well as reed switches.
