Electric Power Systems

Now comprehensively updated, this classic text provides an essential foundation in power systems engineering. The emphasis on practical analysis and modelling, so successful in previous editions, is retained while extensive theory and complex mathematics are avoided. The fourth edition considers new possibilities for energy storage, reviews the effect of electromagnetic fields on human health and explores the impact of privatization on planning, operation and distribution issues. Features of the fourth * Extended coverage of power system components including 2-axis concepts, Flexible a.c. Transmission (FACT) devices and modern switchgear * A new chapter on power system economics and management providing guidance on pricing and markets in the light of recent infrastructure changes * Examination of substations detailing digital protection methods, reliability, security and emergency control * Discussion of system stability and the prevention of voltage collapse * New problems and end of chapter worked examples designed to assist the learning process * Introduction to optimization and optimal power flow calculations * New sections on monitoring and control with SCADA, state estimation and Energy Management Systems (EMS) plus an update on h.v.d.c. transmission Offering enhanced, clear and concise explanations of practical engineering applications, this updated edition will ensure that Electric Power Systems continues to be an invaluable reference for senior undergraduates in electrical engineering.

Electric power systems are going through a period of dramatic change with the need to reduce environmental impact, provide a secure supply of power to an increasing world population while aging infrastructure and equipment in many established systems needs replacing. Today's student has to understand both the large amount of plant and equipment that is in use as well as the possibilities offered by new technologies.

Now comprehensively updated and revised, the fifth edition of this classic textbook provides a modern foundation in power systems engineering. The emphasis on practical analysis, modeling and fundamental principles, so successful in previous editions, is retained together with broad coverage of the subject while avoiding complex mathematics. Throughout, the worked examples and computer simulations used to explain concepts and calculation techniques have been modernised, as have all figures.

Features of the fifth edition:

• Examples of the use of power system simulation programs illustrating fundamental principles
• Revised chapters on load flow, systems stability and electrical transients
• Extended coverage of developments in HVDC including the use of voltage source converters
• A new chapter on power system economics
• Examination of substations and Gas Insulated Switchgear
• Extensive worked examples and end-of-chapter problems to facilitate learning

For instructors and teachers, solutions to the problems set out in the book can be found on the companion website.

Offering enhanced, clear and concise explanation of practical applications, this updated edition will ensure that Electric Power Systems continues to be an invaluable resource for senior undergraduates in electrical engineering.
