An information system for monitoring and diagnosing performance of thermoelectric power plants is a tool to assist in the management of maintenance activities. Therefore, this thesis aims to develop an information system for monitoring and diagnosing thermodynamic performance in a thermoelectric power plant equipped with internal combustion engines, this system can be implemented in an application in MS Windows. In this work, the reference condition is established at ISO conditions based on tests conducted at the plant in operation, and additional technical information. Consequently, for the diagnosis, the actual condition is corrected to ISO conditions. Nevertheless, beyond the reference state defined, for increased reliability of the results was considered another basis for comparison on the basis of information from the manufacturer. Moreover, as the central thermal motogeradoras has 20 equal units, the information system developed proved practical to compare the operating parameters between any two units, seeking an independent analysis of the quality of the reference model.
