Remote control of tennessee valley authority´s Raccoon Mountain pump-storage plant

Compared to the remote control of a conventional generation only plant, the problems encountered with controlling a pumped-storage generating plant are unique and, certainly, more challenging. The fact that the Raccoon Mountain powerhouse and switchyard are separated by approximately 1-1/2 miles (2.44 km), makes the configuration of the data acquisition and supervisory control remote terminals more complex. Two computers are used, one at the powerhouse and one at the switchyard. This configuration eliminates huge quantities of very expensive control cabling between the two structures and provides a more reliable and efficient operation.
