Identification method of cable orientation in substations based on label information flow
Cable orientation recognition is an important part of cable maintenance and construction. The accuracy of identification directly affects the safety of personnel and equipment. This paper proposes an identification method of cable orientation in substations based on label information flow. The label code of each substation is determined according to the number of substations in a predetermined area, and the modulated label signal containing substation information is injected into the shielding layer of the outgoing cable through the grounding network of each substation. After the signal is detected on the cable under test, the tag signal injected by each substation is correlated with the detection signal. The substation with the highest correlation result is the substation connected to the end of the cable under test, so the orientation of the cable can be identified without knowing the attribution of the beginning and end of the cable. The experimental test results verify the accuracy and efficiency of the identification method of the cable direction of the substation based on the label information flow.
