متن کاملInvestigation of Various Condition-Monitoring Techniques Based on a Damaged Wind Turbine Gearbox
The National Renewable Energy Laboratory presented an investigation of various wind turbine drivetrain condition monitoring (CM) techniques at the 7 International Workshop on Structural Health Monitoring held in 2009. The study contained in this report is a continuation of the 2009 paper and focuses on results obtained by various CM techniques from a damaged Gearbox Reliability Collaborative te...
متن کاملDynamic Analysis of Wind Turbine Gearbox Components
Abstract: This paper studies the dynamic response of a wind turbine gearbox under different excitation conditions. The proposed 4 degree-of-freedom (DOF) dynamic model takes into account the key factors such as the time-varying mesh stiffness, bearing stiffness, damping, static transmission error and gear backlash. Both the external excitation due to wind and the internal excitation due to the ...
متن کاملUse of the Teager-Kaiser energy operator for condition monitoring of a wind turbine gearbox
This paper deals with the condition monitoring of a wind turbine gearbox under varying operating conditions, which cause nonstationarity. The gearbox vibration signals are decomposed into a set of monocomponent signals using the Empirical Mode Decomposition (EMD) method. The Teager-Kaiser Energy Operator (TKEO) in combination with an energy separation method is also presented as an alternative ...
متن کاملCondition Monitoring of a Wind Turbine Gearbox using the Empirical Mode Decomposition Method and Outlier Analysis
Wind turbines are subject to variable aerodynamic loads and extreme environmental conditions. Wind turbine components fail frequently, resulting in high maintenance costs. For this reason, gearbox condition monitoring becomes important since gearboxes are among the wind turbine components with the most frequent failure observations. The major challenge here is the detection of faults under the ...
