Utility overhauls its communications backbone: Georgia Transmission Corp. incorporates frame-relay technology into its SCADA system

摘要

In today's environment, a utility must have a reliable supervisory control and data acquisition (SCADA) system to monitor and control its transmission network, and to track the real-time system load. The traditional SCADA system consists of remote terminal units (RTUs) in the substations, a SCADA master station at the headquarters and a telecommunications network connecting the two. If any part of this system fails for an extended period of time, the economic consequences to a utility are devastating. With this in mind, Georgia Transmission Corp. (GTC), Tucker, Georgia, U.S., needed a reliable and effective method to protect its entire SCADA network.
