Download or read book Improving Backup Protection Using Sampled Values for Generating Stations written by Sruthi Chilukuri and published by . This book was released on 2017 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluation of relay misoperations provides an opportunity to improve the design of backup protection schemes. Existing generator station backup protection schemes use distance protection (21) or voltage controlled/restrained overcurrent protection (51V) elements for clearing phase faults that are not cleared by either line protection or generator protection. Many schemes also use transformer ground overcurrent protection (51NG) for backup protection for ground faults on the system. Since generator protection can respond to faults with fault resistance accurately only when there is no remote infeed from the other terminals, designing a secure backup protection for a generating station during remote infeed conditions is a challenge. Apart from the remote infeed, fast response of automatic excitation controllers also affects the current seen by the generator protection relay. Considering these effects, different vendors have different approaches for setting the 21 element. In order to analyze these recommendations, this thesis studies the performance of backup protection schemes applied at a thermal power station connected through a breaker and half scheme using Real Time Digital Simulator (RTDS) simulations. This thesis proposes a new approach to enhance the performance and coverage of backup protection schemes by using the IEC 61850 standard by using measurements from multiple VT locations in the same relay to enhance protection security.. In addition to that, this thesis also address the challenges associated with the existing generator breaker failure protection schemes based on breaker auxiliary contacts and undercurrent elements and proposes a solution using a synchronism check element which uses sampled values. These two techniques can be used in existing generating station protection schemes to improve the reliability and security of these schemes.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers power systems cybersecurity. In order to enhance overall stability and security in wide-area cyber-physical power systems and defend against cyberattacks, new resilient operation, control, and protection methods are required. The cyberattack-resilient control methods improve overall cybersecurity and stability in normal and abnormal operating conditions. By contrast, cyberattack-resilient protection schemes are important to keep the secure operation of a system under the most severe contingencies and cyberattacks. The main subjects covered in the book are: 1) proposing new tolerant and cyberattack-resilient control and protection methods against cyberattacks for future power systems, 2) suggesting new methods for cyberattack detection and cybersecurity assessment, and 3) focusing on practical issues in modern power systems.
