Research on Wind Turbine Blade Monitoring Based on FBG Strain Sensors
نویسنده
چکیده
As an clean renewable energy source wind energy is highly regarded by various countries in the world. Wind turbine blade is one of the most important components in wind turbine. It is the key component for receiving wind energy. As turbine size steps up and the size of modern turbine blade increases, condition monitoring and maintenance of blades become more important. Strain detection is one of the most effective methods to monitor blade condition. Sensitivity for EMC and lightning and zero drift of conventional strain gauges bring a lot of trouble. In this paper, a fibre Bragg grating sensor system is used for blade monitoring. The system overcomes the shortcomings. It is dainty, reliable, convenient to multiplex and so on.

Damage Detection Based on Static Strain Responses Using FBG in a Wind Turbine Blade
The damage detection of a wind turbine blade enables better operation of the turbines, and provides an early alert to the destroyed events of the blade in order to avoid catastrophic losses. A new non-baseline damage detection method based on the Fiber Bragg grating (FBG) in a wind turbine blade is developed in this paper. Firstly, the Chi-square distribution is proven to be an effective damage...
متن کاملField Deployable Fiber Bragg Grating Strain Patch for Long-Term Stable Health Monitoring Applications
A fiber Bragg grating (FBG) strain patch specially adapted for long-term and high-strain applications has been developed and characterized. The design concept for the patch is based on a glass-fiber reinforced plastic (gfrp) carrier material. The developed concept for the FBG integration into the carrier material was derived from reliable integration procedure of FBG sensors into composite stru...
متن کاملOn the development of a sliding mode observer-based fault diagnosis scheme for a wind turbine benchmark model
This paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. The methodology is based on a modified sliding mode observer (SMO) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. The faults are reconstructed using the equivalent output err...

متن کاملAcoustic condition monitoring of wind turbines: tip faults
As a significant and growing source of the world’s energy, wind turbine reliability is becoming a major concern. At least two fault detection techniques for condition monitoring of wind turbine blades have been reported in early literature, i.e. acoustic emissions and optical strain sensors. These require off-site measurement. The work presented here offers an alternative non-contact fault dete...
