the method comprises the steps that equipment hidden dangers of all equipment in a power station are divided into low-level hidden dangers and high-level hidden dangers, the low-level hidden dangers and the high-level hidden dangers correspond to basic scores, the discovered equipment hidden danger scores are displayed through first display scores obtained by multiplying the discovered times of the equipment hidden dangers and the basic scores, the equipment class-I obstacle scores are displayed through second display scores corresponding to the shutdown maintenance times of the power station, different maintenance times correspond to different scores, the defects of all the equipment in the power station are classified, the defects of different classes correspond to different scores, and the defect classification scores are displayed through third display scores corresponding to the defects of different classes;
wherein, the defect ring ratio: the ring ratio is the comparison between the number of the defects generated in the current month and the number of the defects generated in the previous month, namely the defect ring ratio increase number, reflects the development trend of the defect number, and is determined according to the following formula I:
the formula I is as follows:
eliminating the defect rate: reflecting the defect management condition of each unit device, and determining according to the following formula two:
the formula II is as follows:
and (3) discovering the potential hazard score of the equipment: the first display score for discovering equipment hidden danger is determined by the following formula three:
the formula III is as follows:
the equipment class obstacle score is displayed through a second display score corresponding to the shutdown maintenance times of the power station, the lower the score is, the more the equipment class obstacle is, and the second display score is determined by the following formula four:
the formula four is as follows:
number of occurrence of repeated defects: the defects with similar positions, phenomena and types in the defects generated in the current month and the defects generated in the last 3 months are repeated defects, a deduction system is adopted, score display is carried out through display equipment, and the fourth display score of the number of the repeated defects is determined by the following formula five:
the formula five is as follows:
and classifying the defect classification scores, namely dividing factors and factor scores of the defects of the equipment according to the defect occurrence reasons, and determining the factor proportion according to the following formula six: formula six:
then, the formula seven is used:
determining a third display score, wherein
A third display score;
factor specific gravity;
a factor score; k is an adjustment coefficient, k = 2.5;
representing each factor, the display score is the defect classification.
