The prediction of power distribution transformer faults frequency based on high-order Markov

摘要

The accurate prediction of power distribution transformer faults frequency would bring certain economic benefits for electronic companies' production run, in order to avoid outer factors affecting prediction results, high-order Markov is applied to prediction. Firstly we make some preprocessing for the historical series of faults frequency to eliminate their outlier; Then we do the clustering, dividing the historical data into five classifications, next use high-order Markov model to forecast faults frequency and analysis the deviation.
