Abstract：The anti-misoperation locking logic of substation measurement and control is afected by thecomplex and changeable environment on site，which willead to the diffcultyand lowaccuracyof anti-misoperation locking logic verification.This paper proposes a visual intelligentverification method for anti-misoperation locking logic of substation measurement and control.Firstly，diferent types of substation measurement and control anti-misoperationlocking logic standards areanalyzed.Then，a wide-area modeloflogiccoding for multiplelogicsisconstructed according tothelogicstandards.Finally，themodel isused totransformthelogiccoding format，andthe linearregressionequationof intelligent verification is established.Combined with the data visualization process，the anti-misoperation locking logic verification is realized.The experimental results show thatthefalse locking rate of the substation measurement and control anti-misoperation locking logic is 1% ～6 % ，and the fluctuation is small. The PR curve has excelent balance point and high calibration accuracy，which can meet the operation and maintenance management requirements of substation measurement and control work.
