Název projektu:
PS : FP7 CoMoTav Condition Monitoring of Wind Turbines (11 GB 41n7 3MGC)
Popis:
An East of England based research centre requires one large company and two SMEs to complete the consortium for their project which is due to be submitted to the Research for SMEs call in December. The aim of the project is to develop a condition monitoring system for wind turbines. Three partners are required, as described in Technical Specifications field.
This research project seeks to promote the growth of the renewable energy sector in the EU using current and novel technology of condition monitoring and maintenance. Recent research has shown that condition monitoring systems have the potential to provide increased lifecycle earnings for the owners of wind farms through increased availability and decreased maintenance costs. Achieving this goal will require updating condition monitoring and maintenance systems with innovative detection and corrective technologies beyond existing levels.
Increasing vibration and noise levels is an indication that wind turbine machinery are not working properly or working under abnormal conditions. Monitoring of noise and vibration levels is required as an indicator of the health' of machinery in order to schedule maintenance. Detailed analysis of spectral content can be used to diagnose root causes such as, for example, unbalance etc&
Though some noise reduction can be achieved by increasing the damping (adding foam and damping materials), this approach can in general only provide rather limited reductions. If significant attenuations are required it will be necessary to consider the characteristics of the various sources, the propagation paths (both structure-borne and air-borne), sound radiation mechanisms and to introduce modifications where they are most effective.
Passive isolation systems based on pneumatic springs have been used successfully for other applications but have problems with low frequency vibrations (0.5-8Hz) where mechanical resonances cause amplification of the vibration rather than cancellation. However, wind turbine components and machinery require specific effective anti-vibration solutions to achieve maximum performance.
The research aims to:
1. Identify noise location in the machinery based on source localisation using acoustic measurements.
2. Increase the efficiency of the turbine using acoustic measurements
3. Improve the energy capture capability at different wind speeds thereby increasing energy extraction.
4. Correlate active flow control measurements with the acoustic noise pressure control in order to enhance the acoustic level especially for low frequencies.
5. Reduce vibration in the turbine machinery using active vibration for components inside the nacelle.
In addition, correlation of the acoustic noise localisation using accelerometers and acoustic emission sensors located in the gearbox, generator, low and high speed shafts will be developed. The successful development of the different aims will result in the overall noise cancellation which results in low noise impact on the environment and high reliability of the wind turbine machinery and structures.
Technical Specifications / Specific technical requirements:
The proposal is currently under development and is due to be submitted to the Research for SMEs call under the Capacities programme on 6th December 2011. The project duration has been set at 2 years. Further information about project and partner funding will be discussed directly with interested parties.
Three partners are required, all of which are listed below:
- A Large company, end user of wind turbines, for testing/end user role.
- An SME company with expertise in condition monitoring and data acquisition systems focused in dynamic systems and vibrations (i.e. rotatory machinery), to help in the developing of the device and in the data acquisition system.
- An SME company specialized in NDT inspection with experience in vibration analysis, to provide their expertise in the interpretation of results, and to provide guidance in the needs from the inspector point of view. Experience in wind turbine inspection would be desirable.
