Evaluation of CCF of electric energy meter with black screen based on weight adjustment-AHP method
In order to effectively evaluate the CCF of black screen fault of electric energy meter, proposes a common cause failure evaluation method based on dynamic weight adjustment AHP method. This method adopts the deviation weight model of weighted comprehensive decision matrix at the peak time of failure rate, and calculates the influence factor of weight deviation iteratively to obtain the common cause failure The stable and unique deviation weight solves the accuracy problem of experts" artificial judgment weight. Finally, the feasibility and effectiveness of the common cause failure evaluation method are verified by practical cases, which provides a reference for the troubleshooting of black screen of electric energy meter.
