Abstract :
By its very definition, as applied to power system protection, wide-area measurement systems (WAMSs) are a synergistic combination of relays, measuring instruments, control equipment, automation equipment, monitoring equipment, and communication employed to encompass extensive system elements as opposed to the more traditional view of individual equipment or point-to-point protection. The increasing world-wide application of digital devices and high-speed wideband communication and global positioning systems (GPSs) plus the growing acceptance of adaptive relay protection philosophy and practice have dramatically altered the fundamental role of power-system protection.
