Application of Fault Tree Analysis for Evaluating Reliability: A Case Study of Gear Box of Wind Turbine

  • Navneet Singh Bhangu, Sonia Grover

Abstract

The fault tree analysis is used to evaluate reliability of any system which is comprised of repairable and non-repairable components. A fault tree is a diagrammatic representation of all possible fault events, their logical combinations and their relationship to the system failure. This paper presents the reliability evaluation method for gear box of wind turbine using fault tree analysis (FTA). A case study of 1000 MW capacity project set up under the Suzlon Wind Energy has been presented in this paper. The actual failure data of one year has been collected from this plant. Gear box sub-components connected in series/parallel combination have been considered for calculating reliability. The calculated results for gear box are generally in conformity with statistical data, indicating that most of the failures are caused by several basic factors. The low value of reliability of gear box indicates that gear box is most failure prone component and immediate attention/maintenance technique is required to mitigate faults and enhance reliability.
