This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this thesis is to develop a new digital-relaying algorithm for theprotection of the generator in case of loss of its field current. In order to establish this goal the following steps are followed:-Firstly a study of the main protection requirements of an electric generator was done in order to form a common understanding about the most essential protection devices used for this purpose. Loss of field protection of asynchronous generator was given more attention, with special concentration onthe disadvantages of the conventional relaying method based on the applicationof a mho distance relay.-Secondly a study of the operational characteristics of the generator during steady and transient states were done. These studies focus on the reactive power output from the generator, and its characteristics during loss of field.-Thirdly attention is directed to the study of the traditional method used to protect.generators in case of loss of field with concentration on its disadvantages inorder to overcome them in the planned new relaying algorithm. The traditionalmethod uses an offset mho distance relay , which measures the impedance of thegenerator seen at its terminals and compares it to the setting values of the relay .-Then the new algorithm based on the direction of the reactive power flowthrough the generator was introduced. This algorithm measures the movingaverage of the total reactive power output of the generator over a complete cycle of the system frequency and compares it to its setting values.-In the last section a computer simulation study was performed on a representative power system to test the response of this new algorithm for actual loss of field, and for other abnormal operating conditions.-, Finally a collection of conclusions and suggested recommendations were given at the end of this thesis.

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 592 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 2011-07-28 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital Signal Processing in Power System Protection and Control bridges the gap between the theory of protection and control and the practical applications of protection equipment. Understanding how protection functions is crucial not only for equipment developers and manufacturers, but also for their users who need to install, set and operate the protection devices in an appropriate manner. 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.
