Description

The purpose was to develop advanced condition monitoring techniques dedicated for wind turbine drive train and DC-link capacitors.

The novelty of this project is that it uses less number of transducers to accomplish the condition monitoring of the whole wind turbine drive train and partial power electronic control system.

It is hence simpler and more cost-effective in contrast to conventional condition monitoring techniques designed for wind turbines.

  • Research the energy flow of wind turbines (WT), analyse the impacts of various drive train and DC-link capacitor faults, and predict their symptoms
  • Assess existing NDT approaches for capital cost, reliability, and efficiency, identify the desired WT CM approaches
  • Perform tests to collect the desired CM signals under varying loading and operational conditions
  • Perform theoretical research to identify signatures dedicated for CM WT drive train and DC-link capacitor
  • Investigate the CM signals obtained, develop signal processing and data interpretation techniques dedicated for CM WT drive train & DC-link capacitors
  • Verify the developed techniques on Narec’s drive train test rigs
  • Further demonstration of the techniques on real WTs
  • Development of business plan defining Narec’s commercial consultancy product and embedding of the new capability within Narec
