The changing structure of the electric utility industry has had a significant impact on power system design and operation. In particular, the incorporation of flexible a.c. transmission system (FACTS) devices and high voltage direct current (HVDC) links into conventional computational programs presents new challenges in power system modelling. Responding to these changes, Computer Modelling of Electrical Power Systems, Second Edition presents modern analysis tools for the design and improvement of power system performance. This fully revised and updated edition features: * The incorporation of HVDC and FACTS devices in power flow and system stability with detailed descriptions of the relevant algorithms. * Extensive coverage of the EMTP (electromagnetic transient program) method - a key development in power system simulation. * The use and impact of personal computers in power system simulation, with emphasis on efficient computational techniques for interactive work. Practising engineers involved in the power system industry will value this timely update of a classic reference. Researchers and advanced electrical engineering students will appreciate the clear treatment of the latest analytical techniques.Jos Arrillaga is the author of 'Computer Modelling of Electrical Power Systems', published 2001 under ISBN 9780471872498 and ISBN 0471872490.
