Zusammenfassung:The invention provides a power distribution network defect positioning method and device based on security domain sag visualization, and is suitable for the field of power distribution network security domains. Carrying out first concave boundary identification on the security boundary of the security domain through full-dimensional observation, carrying out second concave boundary identification on the security boundary of the security domain through Monte Carlo two-dimensional observation, and carrying out mutual verification on the concave boundary identified for the first time and the concave boundary identified for the second time to determine a target concave boundary; directly observing the local part of the power distribution network based on the target recess boundary; and determining the power distribution network defect based on the target sag boundary. According to the method, for a given power distribution network, through combination of full-dimensional indirect observation, Monte Carlo two-dime
