Failure modes and effects analysis system deployment in a wind turbine at high uncertain wind environment

This paper presents the results for the Failure Modes and Effects Analysis (FMEA) performed for the Wind turbines (WT) located in a high uncertain wind environment. The FMEA was carried out for Wind Turbine System (WTS) and its sub assemblies to check the design reliability of twenty numbers of 250 kW WTs, located in Muppandal, India, over the span of 15 years. The WTs situated in high windy region have different kinds of modes of failure than the low wind region. The reliability software tool used to analyze this study is Reliasoft's Xfmea Version 5.1.1. The results show that considerable improvements in the reliability of WTs are obtained by modifying and redesigning some WT components, by implementing redundancy system for the yaw system and sensors, effective monitoring mechanism for brake system and gear system and proper preventive maintenance of all WT components.
