Wind turbine vibration monitoring based on finite-element (FE) simulation
The design of wind turbines evolved over time, with the scope of becoming less expensive and producing energy more efficiently. This paper deals with a FEM model for the representation of vertical axis wind turbine (VAWT) functioning for diagnostic and monitoring studies, which can provide fundamental data that can optimize the design of the monitoring system and an improvements in fault diagnosis related to vibration effects. In particular in this paper will discuss a monodimensional VAWT model, in order to reduce the computational time and, at the same, by using low computational resources to analyze several load cases. Growing usage of wind turbines has made maintenance a priority, and diagnosing potential faults is crucial to maintaining the turbine's desired availability. The simulation data obtained by the proposed approach allows to optimize condition monitoring and fault diagnostic techniques by the analysis of the wind turbine behavior before the real use on the field with both time and costs reduction.
