Pitch System
Repeated Angle Errors Traced to Pitch Encoder Failure
"Kavaken identified a pitch control malfunction that was causing notable production loss. The root cause was traced to a faulty pitch encoder, which was replaced by the OEM, restoring normal operation."
The Impact
30 MWh production increase
The Issue
A malfunction was detected in the pitch control system, with repeated 'angle monitoring' errors affecting blade A and leading to turbine stops. The issue resulted in energy loss until the root cause was identified and resolved.
The Action
Kavaken flagged a pitch system anomaly linked to angle monitoring errors and reported significant production loss. After confirming the persistence of the issue, the OEM (Enercon) replaced the faulty pitch encoder. Following the intervention, the turbine returned to normal operation with no further errors observed.
