Fault diagnosis and prognosis capabilities for wind turbine hydraulic pitch systems [PDF]
Mechanical Systems and Signal Processing, 2023 Wind energy is the leading non-hydro renewable technology. Increasing reliability is a key factor in reducing the downtime of high-power wind turbines installed in remote off-shore places, where maintenance is costly and less reactive. Defects in the pitch system are responsible for up to 20% of a wind turbine downtime.Thus, monitoring such defects is ...

Friction Estimation for Condition Monitoring of Wind Turbine Hydraulic Pitch System
IFAC-PapersOnLineFaults and wear in hydraulic pitch actuators of wind turbines significantly contribute to downtime of remote of-shore wind farms. This study presents a method for estimating incipient friction in the hydraulic actuator, which is directly associated with faults and wear in the pitch system.
