The Mechanism of grey prediction method and its application advantages in safety prediction were described.This method was used to predict the vibration amplitude within the coming 6 hours for a steam turbine.Moreover
the prediction results were examined using correlation degree and posterior error.Results indicated that
this grey prediction method had small posterior error and got a grade I accuracy.We can foreknow the variation trend of vibration amplitude of the steam turbine through this method
so as to take timely countermeasures.Therefore
the operation safety of the power unit was improved.
