To improve the accuracy of secondary virtual circuit faults,a precise positioning method for secondary virtual circuit faults in switch operation boxes based on digital twin technology is proposed.Based on the current positioning requirements,first clarify the fault characteristics of the secondary virtual circuit.Then,a multi-component approach is adopted to break the coverage limitations of traditional positioning methods,design a multi-component self checking alarm BPA positioning structure,and construct a secondary virtual circuit fault positioning model for the digital twin switch operation box.Finally,an evidence-based test processing method is used to achieve fault positioning.The test results indicate that for the selected 6 test areas,the number of false positives for fault location of the new method is controlled below 5,indicating that with the assistance of digital twin technology,the new method has more application value.
