This book was released on 2015-06-18 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transient response of the voltage on the secondary is investigated with following changes in the model. Two instants of switching are considered. Instrument transformers are the integral components of power systems .Capacitive Voltage Transformers (CVTs) are widely used for protection, metering and control applications. The work presents the modeling of CVT by its equivalent circuit. A 420kV CVT is considered with a line to ground fault on the primary side. Another kind of transient response called ferro resonance is also studied. Three types of ferro resonance suppression circuits (FSCs) are considered to dampen the behavior due to ferro resonance The parameters of these FSCs are discussed. The impedance, power characteristics of these FSCs with variation of frequency are studied. Furthermore, using metal oxide varistors are used to improve the performance of the FSCs.The two switching instants in presence of FSC are also evaluated .The effect of FSCs on the transient response of CVTs are presented in this work. The effect of magnetizing current of intermediate voltage transformer on the transient response is also simulated.

Download or read book Transient Analysis of Power Systems written by Juan A. Martinez-Velasco and published by John Wiley & Sons. This book was released on 2015-01-27 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simulation of electromagnetic transients is a mature field that plays an important role in the design of modern power systems. Since the first steps in this field to date, a significant effort has been dedicated to the development of new techniques and more powerful software tools. Sophisticated models, complex solution techniques and powerful simulation tools have been developed to perform studies that are of supreme importance in the design of modern power systems. The first developments of transients tools were mostly aimed at calculating over-voltages. Presently, these tools are applied to a myriad of studies (e.g. FACTS and Custom Power applications, protective relay performance, simulation of smart grids) for which detailed models and fast solution methods can be of paramount importance. This book provides a basic understanding of the main aspects to be considered when performing electromagnetic transients studies, detailing the main applications of present electromagnetic transients (EMT) tools, and discusses new developments for enhanced simulation capability. Key features: Provides up-to-date information on solution techniques and software capabilities for simulation of electromagnetic transients. Covers key aspects that can expand the capabilities of a transient software tool (e.g. interfacing techniques) or speed up transients simulation (e.g. dynamic model averaging). Applies EMT-type tools to a wide spectrum of studies that range from fast electromagnetic transients to slow electromechanical transients, including power electronic applications, distributed energy resources and protection systems. Illustrates the application of EMT tools to the analysis and simulation of smart grids.

Download or read book Fault Location on Power Networks written by Murari Mohan Saha and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fault Location on Power Lines enables readers to pinpoint the location of a fault on power lines following a disturbance. The nine chapters are organised according to the design of different locators. The authors do not simply refer the reader to manufacturers’ documentation, but instead have compiled detailed information to allow for in-depth comparison. Fault Location on Power Lines describes basic algorithms used in fault locators, focusing on fault location on overhead transmission lines, but also covering fault location in distribution networks. An application of artificial intelligence in this field is also presented, to help the reader to understand all aspects of fault location on overhead lines, including both the design and application standpoints. Professional engineers, researchers, and postgraduate and undergraduate students will find Fault Location on Power Lines a valuable resource, which enables them to reproduce complete algorithms of digital fault locators in their basic forms.

Available in PDF, EPUB and Kindle. Book excerpt: This book builds on the cutting edge research presented in the previous edition that was the first of its kind to present the technology behind an emerging power systems management tool still in the early stages of commercial roll-out. In the intervening years, synchrophasors have become a crucial and widely adopted tool in the battle against electricity grid failures around the world. Still the most accurate wide area measurement (WAMS) technology for power systems, synchronized phasor measurements have become increasingly sophisticated and useful for system monitoring, as the advent of big data storage allows for more nuanced real-time analysis, allowing operators to predict, prevent and mitigate the impacts of blackouts with enhanced accuracy and effectiveness. This new edition continues to provide the most encompassing overview of the technology from its pioneers, and has been expanded and updated to include all the applications and optimizations of the last decade.
