Description:
Electrical Engineering Understanding FACTS Concepts and Technology of Flexible AC Transmission Systems
The Flexible AC Transmission System (FACTS) a new technology based on power electronics offers an
opportunity to enhance controllability, stability, and power transfer capability of ac transmission systems.
Pioneers in FACTS and leading world experts in power electronics applications, Narain G. Hingorani and
Laszlo Gyugyi, have teamed together to bring you the definitive book on FACTS technology. Drs. Hingorani
and Gyugyi present a practical approach to FACTS that will enable electrical engineers working in the power
industry to understand the principles underlying this advanced system. Understanding FACTS will enhance
your expertise in equipment specifications and engineering design, and will offer you an informed view of
the future of power electronics in ac transmission systems. This comprehensive reference book provides
in–depth discussions on:
- Power semiconductor devices
- Voltage–sourced and current–sourced converters
- Specific FACTS Controllers, including SVC, STATCOM, TCSC, SSSC, UPFC, IPFC plus voltage regulators, phase
shifters, and special Controllers with a detailed comparison of their performance attributes
- Major FACTS applications in the U.S.
Understanding FACTS is an authoritative resource that is essential reading for electrical engineers who want
to stay on the cusp of the power electronics revolution.
