摘要
A method for defect pre-warning of a power device may comprise processing measurement data regarding components of the power device based on predetermined severity criteria, to obtain severities of monitoring indexes related to defects of the components. Weights of the monitoring indexes with respect to the defects are determined based on effectiveness of the monitoring indexes for the defects. A defect probability that at least one of the components has each of at least one of the defects is estimated based on the severities and the weights. Some embodiments may achieve more reliable defect probability estimation and in some embodiments defective component probability and/or device healthy may be estimated. Based on the reliable information, it may facilitate to arrange the maintenance before defects involve into a fault and assess a risk of power device operation and control, thereby improving reliability of the power device.
