There are several reasons why the wind turbine generator can fail, including wind loading, weather extremes, and thermal cycling. Mechanical or electrical failure of the bearings, excessive vibration, voltage irregularities, and cooling system failures can lead to excessive heat and fire. Fault Tree Analysis (FTA) is a graphical tool to explore the causes of system-level failures. As shown in the attached diagram, a vessel operation fault tree analysis is an instrument that can measure either directly or indirectly the volume of a substance that is passing through a specific location in a set period of time. Instead of creating a vessel operation Fault Tree Analysis diagram from scratch, try using EdrawMax’s pre-built templates for FTA that can make the entire designing process extremely effective.
