Introduction to FACTS Controllers

Demystifies FACTS controllers, offering solutions to power control and power flow problems

Flexible alternating current transmission systems (FACTS) controllers represent one of the most important technological advances in recent years, both enhancing controllability and increasing power transfer capacity of electric power transmission networks. This timely publication serves as an applications manual, offering readers clear instructions on how to model, design, build, evaluate, and install FACTS controllers. Authors Kalyan Sen and Mey Ling Sen share their two decades of experience in FACTS controller research and implementation, including their own pioneering FACTS design breakthroughs.

Readers gain a solid foundation in all aspects of FACTS controllers, including:

• Basic underlying theories

• Step-by-step evolution of FACTS controller development

• Guidelines for selecting the right FACTS controller

• Sample computer simulations in EMTP programming language

• Key differences in modeling such FACTS controllers as the voltage regulating transformer, phase angle regulator, and unified power flow controller

• Modeling techniques and control implementations for the three basic VSC-based FACTS controllers—STATCOM, SSSC, and UPFC

In addition, the book describes a new type of FACTS controller, the Sen Transformer, which is based on technology developed by the authors. An appendix presents all the sample models that are discussed in the book, and the accompanying FTP site offers many more downloadable sample models as well as the full-color photographs that appear throughout the book.

This book is essential reading for practitioners and students of power engineering around the world, offering viable solutions to the increasing problems of grid congestion and power flow limitations in electric power transmission systems.
