This book provides a comprehensive practical treatment of the modelling of electrical power systems, and the theory and practice of fault analysis of power systems covering detailed and advanced theories as well as modern industry practices. The continuity and quality of electricity delivered safely and economically by today''s and future''s electrical power networks are important for both developed and developing economies. The correct modelling of power system equipment and correct fault analysis of electrical networks are pre-requisite to ensuring safety and they play a critical role in the identification of economic network investments. Environmental and economic factors require engineers to maximise the use of existing assets which in turn require accurate modelling and analysis techniques. The technology described in this book will always be required for the safe and economic design and operation of electrical power systems. The book describes relevant advances in industry such as in the areas of international standards developments, emerging new generation technologies such as wind turbine generators, fault current limiters, multi-phase fault analysis, measurement of equipment parameters, probabilistic short-circuit analysis and electrical interference. *A fully up-to-date guide to the analysis and practical troubleshooting of short-circuit faults in electricity utilities and industrial power systems *Covers generators, transformers, substations, overhead power lines and industrial systems with a focus on best-practice techniques, safety issues, power system planning and economics. *North American and British / European standards covered

"In a world of huge, interconnected networks that can be completely blacked out by disturbances, POWER SYSTEM PROTECTION offers you an improved understanding of the requirements necessary for prompt and accurate corrective action. P. M. Anderson, a noted expert on power systems, presents an analytical and technical approach to power system protection. His discussion shows how abnormal system behavior can be detected before damage occurs, and points to effective control action to limit system outages. Advance your knowledge of power system protection through a better understanding of: Protective devices and controls Protection concepts Transmission protection Apparatus protection System aspects of protective systems Reliability analysis of protective systems POWER SYSTEM PROTECTION is expressly written for practicing engineers and advanced graduate-level student engineers who need a comprehensive resource on the principles of power system behavior. This essential reference work provides new and advanced concepts for understanding system performance."

The development of power semiconductors with greater ratings and improved characteristics has meant that the power industry has become more willing to develop new converter configurations. These new configurations take advantage of the higher controllability and switching frequencies of the new devices. The next few years will decide which of the proposed technologies will dominate future power transmission systems. Flexible Power Transmission is a comprehensive guide to the high voltage direct current (HVDC) options available, helping the reader to make informed decisions for designing future power transmission systems. The book includes: An excellent reference for professional power engineers, Flexible Power Transmission is also a useful guide for power system researchers as well as lecturers and students in power systems and power electronics disciplines. a full description of the principles and components in existing converter technology, as well as alternative proposals for self-commutating conversion; A review of the state of power semiconductors suited to HVDC transmission and present proposals for multi-level HVDC transmission. a detailed overview of the flexible HVDC methods for improving controllability and increasing power transfer capability in electrical power systems. up-to-date information on thyrisistor-based HVDC technology. coverage of new pulse width modulation (PWM) transmission technology and multi-level voltage source conversion (VSC) and current source conversion (CSC).

Los motores de aviación son un pilar fundamental sobre el que se asienta la seguridad en vuelo, y el propio vuelo en sí. Gracias a ellos la humanidad ha podido cubrir distancias enormes en corto tiempo, ha permitido el acercamiento de culturas y pueblos, y por tanto ha sido un agente imprescindible en el fenomeno de la globalizacion.En muy poco tiempo pensemos que la aviacion tiene poco mas de un siglo de existencia este sector de la industria aeronautica ha sufrido una enorme transformacion, logrando que los motores de aviacion alcancen prestaciones excepcionales con el minimo peso, y cumpliendo una fiabilidad en vuelo muy superior a la que se exige en otras industrias. Si a ello unimos las exigencias de compromiso con el medio ambiente y otras de tipo economico, tales comoun bajo consumo de combustible, es facil suponer que estos motores se hayan visto sometidos a profundas transformaciones tecnologicas para alcanzar esos logros.En esta nueva obra de la coleccion Cuadernos Aena, su autor, Alberto Garcia Perez, ingeniero aeronautico y periodista, nos presenta perfectamente estructuradas todas las disciplinas que confluyen en el diseño de un motor desde su fabricacion, mantenimiento, la aerodinamica, la mecanica, etc. y que contribuyen a un comportamiento optimo del mismo en todo momento. Una obra que aporta una vision de conjunto de una actividad tan a menudo excesivamente especializada.Indice de la publicacion:1.

El ruido se ha convertido en las sociedades modernas en uno de los agentes más preocupantes de contaminación ambiental. El presente trabajo intenta contribuir al conocimiento del fenómeno que denominamos ruido con el objeto de facilitar la eleccion y aplicacion de las soluciones constructivas mas adecuadas. Sus paginas recogen una serie de temas que, sin duda resultaran de utilidad a los estudiantes que cursan materias que incorporan el aislamiento acustico en sus programas docentes y a todos aquellos agentes que en su practica profesional tengan que dar respuesta a las exigencias que plantea la presencia del ruido en los edificios.

Este libro pretende dar a conocer las cavidades existentes, tanto naturales como artificiales y los abrigos con arte rupestre de la comarca de Cuencas Mineras. Todas las cavidades aquí presentadas están acompañadas de su respectivo plano topográfico, ficha técnica, acceso y descripción de la cavidad, ilustrado todo ello con fotografías que dan una idea de sus características.Al final del libro se incluye un pequeño glosario para un mayor entendimiento de aquellos que sean profanos en la materia. Los accesos se han descrito con minuciosidad, además de información específica de GPS; para ello se han incluido tanto las coordenadas U.T.M. como las sexagesimales.
