We’ve had the weirdest problem
lately. The wind turbine starts making a clanking noise and then when wind dies
off it won’t start again without taking the tower down. Once the tower is down, everything seems good
with breaks off blades turn freely. Once
back up and running a while, clanking/scrapping noise comes back. Strange thing this is that you would think
clanking would be worse at high speed rotation, but it seems to be less
frequent or loud at high speeds.
For a few days were were getting a blank white screen on the HMI too, but power cycling it seemed to fix it for while.
Anyone have any ideas what it could be causing this noise?
Scott said if it was the bearings the noise would track with the speed of
rotation, but it does not. Each time we
take it down, it looks okay in side. After being down it works again for a while.
Right now the HMI shows all is well, it is tracking wind,
breaks are off, but the blades will not turn at all no matter what the wind
speed is.
We’ll take it down again when we get a chance and we’ll
video tape the clanking noise.
December results were
terrible due to this issue.
