5.1 Wind Turbine Troubleshooting
5.1.1 Wind Turbine Vibration
Wind turbine vibration is mainly caused by the following factors:
1) The blades mounting bolts get loose and need to be tightened;
2) The surface of blades gets frozen and needs to be removed;
3) The blades have been distorted, defected and need to be replaced.
4) The tower is not strong enough or guy rope gets loose, and needs to be reinforced or tightened;
5) The wind turbine operates lacking phase, need to check if the three-phase output voltage is balanced or not by testing with multimeter.
IMPORTANT:
Turbine operation should be stopped as soon as abnormal vibration happened till problems solved to avoid personnel or
machine damaged.
5.1.2 Wind Turbine Insensitive to Adjust Rotor Direction
1) HYE wind turbine mainly adopts tail yawing to adjust the blades direction, if it is not sensitive to adjust blades direction, reasons may be: the
turbine alternator shaft is damaged, or the tower is out of plumb.
2) The tower flange is not matching with the flange on turbine, which cause the interference to adjust the wind turbine facing direction.
check
①
if the flange is provided by HYE or in accordance with HYE flange drawing; check if the flange
②
on turbine is loose, and if the axis of
rotation fall into the tower.
3) The wind turbine is in a swinging or seeking status: the wind
①
turbulence caused by natural factors is normal; improperly located,
②
if
turbulence is caused by buildings, wind turbine should re-locate another good position.
