Download or read book Protective Relaying for Power Generation Systems written by Donald Reimert and published by CRC Press. This book was released on 2017-12-19 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, according to the improvement of industries, and the growth of the population, the need for high-quality energy is felt more and more. One of the significant challenges in designing distributed power networks is providing reliable protection with the target of decreasing blackouts. This goal can be achieved by detecting faults in the power system and action to correct or remove the faults. In most cases, taking correct and quick remedial action to protect the power system is done by tripping. Generally, the protective relaying equipment is responsible for tripping in a power system. In this thesis, various types of remedial action schemes for power system performance enhancement using protective relaying are studied in detail. The concept of power system protection consists of protection components, and their functionality is illustrated. Furthermore, several types of protective relays, and their general operating and design considerations are briefly investigated. Several protective relays such as analog overcurrent relay, digital overcurrent relay, and digital under-over frequency relay are investigated, modeled, and simulated in this thesis. To study the power system frequency response, the System Frequency Response (SFR) model is derived and simulated in MATLAB Simulink environment, and the effect of some parameters of a generator on the system's frequency response is examined. Additionally, a new method to model power system frequency response is proposed based on the factorial design method using the Design of Expert. The actual system and the final model are simulated, compared, and validated. The result shows that the model based on the proposed method can be used to estimate the system frequency response. The concept of load curtailment (load shedding) and its different methods are discussed. A conventional underfrequency load shedding relay is simulated in MATLAB software to show how load shedding relays can enhance power system performance. The significant factors which affect power system stability are identified. To show the effect of significant factors on power system stability, a standard IEEE 9-Bus and the IEEE 10-Generator 39-Bus New England Test System are simulated in the PowerWorld. Finally, the concept of autoreclosing is studied in detail. An autorecloser relay is designed, simulated, and examined in MATLAB Simulink, and the proposed relay's units are explained. Optimal autoreclosing methods are also presented in this thesis.

Download or read book Calculations of Protective Relay Settings for a Unit Generator Following Catastrophic Failure written by Jaime Anthony Ybarra and published by . This book was released on 2011 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: After a catastrophic failure of a unit generator system the major components may need to be replaced. Many times exact replacement of the failed or damaged components may not be possible. In such a case components with electrical characteristics as close to the original may be used. Therefore new protective relay settings must be calculated. In this thesis, we will examine a type of generator protection relays, evaluate new settings and develop a one-line diagram for a 25 MVA generator system. A methodology for the development of a safe and reliable protections scheme for a unit generator system is also presented.

This book was released on 2012 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication describes the characteristics of the electrical grid system that are required for the connection and successful operation of a nuclear power plant, as well as the characteristics of a nuclear power plant that are significant for the design and operation of the electrical grid system. It addresses the issues to be considered when a nuclear power plant is being planned and describes the information exchange necessary between the developer of a nuclear power plant and the organization responsible for the electrical grid. The particular issue of a large nuclear unit connected with a small system is also discussed. A new topic introduced in this publication is the need for cyber security of the grid system near the nuclear power plant. Several case studies of Member States experience in developing new nuclear units and about grid events during operation are included.
