abstract
The use of protective relaying scheme in mitigating the causes and risks of wide area disturbances was discussed. Better detection and control strategies through the concept of wide area disturbance protection offer a better management of the disturbances and significant opportunity for higher power transfers. A major component of the system-wide disturbance protection is the ability to receive system-wide information and commands via the data communication system and to send local information to the SCADA center. It is estimated that the advanced measurement and communication technology in wide area monitoring and control, FACTS devices, and new paradigms may provide better ways to detect and control an emergency.
