Fuzzy Diagnostic Systems of Rotating Machineries, Some ELETRONORTE´s Applications

This work reports the project of an expert predictive system used for on line diagnosis of problems in electric equipments used in energy generation and transmission power plants. Some times, the use of corrective maintenance increases the production costs and reduces the resource availability in electric power plants. Detailed observation of the behavior of complex equipments along the time allows fast and reliable identification of an anomaly. In some cases, the anomalous behavior lead to production discontinuities in the plant, a common situations when obsolete preventive maintenance methods are used. Using the tool described in this work, these situations are avoided and the maintenance costs are reduced. The diffusion of this type of paradigm in generation and transmission power plants allows a cheaper energy with more quality to the final consumer.
