PINO GOMEZ, Joel et al. Maintenance importance of mechanical elements and faults in steam turbines: Data history analysis. Energética [online]. 2017, vol.38, n.2, pp. 106-114. ISSN 1815-5901.

Fault diagnosis in steam turbines is a very important task in power industry maintenance due to its influence on the reliability of power stations. However, research papers that specifically are referred to the determination of the most critical mechanical components and faults in steam turbines cannot be found. This work is focused to determine the most important components and faults in steam turbines in a Cuban power plant. For this purpose, the analysis of history data, since 1999 to 2014, of three 100 MW steam turbines was accomplished. The main achievement of this work was the definition of the most important components and faults, and that was attained by defining a new index (called as "importance" index), which intends to overcome limitations imposed by the specific characteristics of available data

Palavras-chave : steam turbines; mechanical elements; faults.
