Abstract :
The use of a PC-based system to record the speed of the shaft on five of Utah Power & Light´s largest steam turbine-generator units is described. This quantity will be fed to special protective relays. The relays are designed to detect mechanical resonance with natural frequencies below 60 Hz, called subsynchronous resonance.<>
