This accurate prediction in the preface to the Third Edition of the Protective Relay Application Guide (PRAG), 1987, has been followed by the rapid development of integrated protection and control devices. The change in technology, together with significant changes in Utility, Industrial and Commercial organisations, has resulted in new emphasis on Secondary Systems Engineering. In addition to the traditional role of protection & control, secondary systems are now required to provide true added value to organisations.
When utilised to its maximum, not only can the integration of protection & control functionality deliver the required reduction in life-time cost of capital, but the advanced features available (Quality of Supply, disturbance recording and plant monitoring) enable system and plant performance to be improved, increasing system availability.
The evolution of all secondary connected devices to form digital control systems continues to greatly increase access to all information available within the substation, resulting in new methodologies for asset management. In order to provide the modern practising substation engineer with reference material, the Network Protection & Automation Guide provides a substantially revised and expanded edition of PRAG incorporating new chapters on all levels
of network automation. The first part of the book deals with the fundamentals, basic technology, fault calculations and the models of power system plant, including the transient response and saturation problems that affect minstrument transformers.
The typical data provided on power system plant has been updated and significantly expanded following research that showed its popularity. The book then provides detailed analysis on the application of protection systems. This includes a new Chapter on the protection of a.c. electrified railways. Existing chapters on distance, busbar and generator protection have been completely revised to take account of new developments, including
improvements due to numerical protection techniques and the application problems of embedded generation. The Chapter on relay testing and commissioning has been completely updated to reflect modern techniques. Finally, new Chapters covering the fields of power system measurements, power quality, and substation and distribution automation are found, to reflect the importance of these fields for the modern Power System Engineer.
The intention is to make NPAG the standard reference work in its’ subject area - while still helping the student and young engineer new to the field. We trust that you find this book invaluable and assure you that any comments will be carefully noted ready for the next edition.برچسب ها:Book electrical protection systems in English electrical protection systems Articles of electrical protection systems electrical protection systems equipment electrical protection systems networks electrical protection systems for electric motors purchasing of electrical protection systems electrical protection systems Book Conservation Network electrical electrical protection and power plants Posts Articles in Home
