Diagnostic Of A Thermal Power Plant Turbo-Alternator Group

Abstract In thermal power plants, Turbo-Alternator Groups (TAG) are classified as vital machinery, whose unavailability leads immediately to a waste of electricity production. They can also be a fault isolation that may result in grave accidents threatening directly the safe operation of the machine as well as the personnel safety. The inspection service is the most efficient solution to decrease the probability of such an accident; particularly the vibratory monitoring which can detect mechanical and electrical defects at a precautionary age. In this article, we present various vibration analysis techniques that we have applied to the TAG of the thermal central plant, in order to perform an effective diagnosis.
