Wind turbine blades condition assessment based on vibration measurements and the level of an empirically decomposed feature

Reliability assessment of generic geared wind turbines by GTST-MLD model and Monte Carlo simulation

“…However, depending on the wind turbine system, more sensors may exist. For example, accelerometers can be installed to measure the vibration created by a component like the low speed shaft, the gearbox, the high speed shaft or the generator [15].…”

“…Reliability models focusing on specific components or subassemblies have been developed, including Miner's rule approach [10e12], neural networks [13], 3D finite element formulations [14,15], non-homogeneous Poisson processes [16] and Markov processes [17e19]. They allow reliability assessment to be performed at the component/subassembly level but not at the wind turbine system level.…”

Feasibility study on a strain based deflection monitoring system for wind turbine blades

“…And a three bladed wind turbine vibration is examined to determine the presence of cracks using accelerometers [8]. Fleming et al [9] calculated the parameters of the blade model to know the structural dynamic response of the blade.…”

Study of Autoregressive (AR) Spectrum Estimation Algorithm for Vibration Signals of Industrial Steam Turbines

“…When faults occur to a turbine, the spectral energy distribution of its vibration signal often changes. Therefore, spectral analysis of the vibration signal can provide efficient reference for the fault diagnosis [7]. In this study, we investigated AR power…”
