Abstract :

The need to establish power plants to supply the required electricity of the country has been rising dueto increasing demand levels as well as the lack of governmental resources. Furthermore, the availabletraditional attitude in performing and conducting power plant projects has made government seek amodern attitude. This paper tries to use the topics that have been employed in automotive industry of thecompany for many years to detect and analyse failure reasons as well as the solutions that are suggestedto prevent and improve them. The present study has used Failure Mode & Effects Analysis along withData Envelopment Analysis to evaluate 17 failure modes of South Esfahan Power Plant. Severity,Occurrence and Detection are 3 failure factors considered in this study. Failure mode dealing with Scalingon rotor and diaphragms blades has the highest importance with the highest Risk Priority Number,Severity and its first grade.
