Performance check of wind turbines

Site: medium size wind farm in Belgium

Procedure:

  • combination of analyses of SCADA data and a nearby wind measurement
  • comparison to reanalyses data, met station data and aj production indices

Results:

  • inconsistencies related to the power curve could be detected

Re-assessment of energy production

Site: medium size wind farm in Northern Germany; the real energy production is much lower than calculated in the original assessment report

Procedure: profound analysis of SCADA data

Results:

  • A lower long term mean wind resource must be assumed when

Re-assessment of wake losses

Site: small wind farm in Germany; the client assumes distinctly higher wake losses than calculated in the original assessment report

Procedure: profound analysis of SCADA data, adapted model calculations

Results:

  • The wind rose of the met station data used in
