Electric power systems are facing new challenges. Limitations to building new transmission lines and generating stations are reducing security margins. New generation sources and free energy markets are creating variables and less predictable power flows. Blackouts in different countries confirm the need to seek modern protection, control, and monitoring solution.These modern solutions are the focus of this book.
Modern technology provides the tools to meet new power system requirements with reliable and affordable solutions. Modern relays feature advanced protection functions as well as control, monitoring, and communications functions. Today, relays and meters also include time-synchronized measurment abilities. Modern communications technology provides fiber-optic and low-cost radio links and makes precise time available over wide areas. New devices enhance cybersecurity.
A general objective of this book is to bring together all engineers working on power system operation, planning, asset management, maintenance, protection, control, monitoring, and communications. These engineers solve modern power system problems, benefit from the new tools available, and face the challenges of properly applying these tools. This book is suitable for protection, control, communications, and power system engineers, decision - making personnel of electric utilities and industry, and university students and faculty.
