Análise de métricas de desempenho de geradores em uma usina termoelétrica.

Abstract

With the changes in the Brazilian energy matrix that have been occurring in the past few years due to the water crisis, researches in the thermoelectrical field become more and more relevant. In the research described here, from a documentary analysis of the operational registers and environmental reports of a thermoelectric power plant, were developed probabilistic researches of performance metrics of the plant in question. These analysis were divided in: correlation analysis and specific fuel oil consumption and efficiency analysis, where were studied different metrics, with different approaches. The first analysis provides indications that correlation coefficients between the studied performance metrics do not follow a rule, as they vary according to the analyzed engine. The result of the following analysis was that quantities like specific consumption and efficiency have remained nearly constant during the whole analysis period. However, it was not possible to obtain conclusive results, since the environmental performance metrics (atmospheric emissions) database was too restrict. However, the analysis is promising, since that a database ampliation may provide the company a deeper analysis between the performance metrics in the power generation of a thermoelectric plant.
