Fault detection– Cross relation of faults and measurements on hydrogenerator
Faults analysis process:
- Cross correlation of signal vector components in
different operating modes (e.g. Run up, steady state,
partial load etc.)
- Comparison to reference data in different operating
modes
- Change detection
- Fault analysis
