Relay protection is a mixture of art and science. Engineers, utilities and companies all have different philosophies about generator protection. This book works through setting a multifunction digital relay for a specific generator from beginning to end. The book also demonstrates PRC compliance. Many books have been written on the theory, principles and application of generator protective relaying. Therefore, the theory in this book is very concise and to the point.
Protection of Wind Turbine Generators Using Microcontroller-Based Applications focuses on the application of microcontrollers in the protection of wind turbine generators. The book looks at the design and implementation of a versatile digital overcurrent (OC), OV/UV, OF/UF, and negative sequence relays, and addresses the dynamic behaviour of a wind-driven induction generator (IG) connected to a power system grid through a transmission line. The transient responses of protective devices associated with the IG are also studied. Modelling of the digital relay for wind turbine generator protection using MATLAB Simulink consider most of the aerodynamic and mechanical effects that can influence instantaneous output voltage, current, and power. Coverage also includes different AC fault types, a detailed theoretical analysis of fault and protection strategy in AC fault, and the different types of fault detection algorithms to maintain power system reliability.
The new edition aims to simplify the math, emphasize the theory, and consolidate the information needed by electrical engineers and technicians who support operations, maintenance, protective relay systems, and betterment projects for generating stations and industrial facilities. It begins with a cursory review of basic electrical phenomenon and then provides additional insights into electrical theory. Single phase and three phase electrical theory is explained in a simplified manner that is not presented in other books. All chapters have been expanded and updated, with the inclusion of an entirely new chapter.

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
