Woelfel

Functions:

Optimization of operation

  • Measurement of vibration stress and output of warning messages when threshold values are exceeded (ISO 10816-21/VDI 3834)
  • Frequency distribution of RMS values (e.g. annual cycle)
  • Wind farm monitoring to locate heavily loaded turbines
  • Monitoring of natural frequencies (tracking, long-term monitoring and trend analysis) to verify structural integrity
  • Unbalance indicator for aerodynamic unbalance and mass unbalance (for wind farm monitoring)

Lifetime prognosis

  • Lifetime prognosis for each tower segment
  • Classification of stresses according to operating conditions
  • Lifetime consumption trend
  • Valid statements for the lifetime extension of the turbine (also in case of retrofit)

Performance

  • Energy self-sufficient monitoring function (recording up to 3 months without energy supply)
  • Connection to the Wölfel monitoring portal MIC.Tower
  • Interface for external sensors (three-channel sensors)
  • Frequency range: 0.1 – 10 Hz
  • Measuring range: ± 2 g
