Zusammenfassung:The invention discloses a power distribution network ground fault monitoring judgment and network type protection self-healing method, particularly relates to the technical field of power distribution network ground fault monitoring, and comprises a power distribution network ground fault monitoring and automatic removal technology and a network type protection self-healing control technology. The power distribution network grounding fault monitoring and automatic removing technology comprises the following specific technical steps: step 1, single-phase grounding faults are judged according to different line conditions; step 2, aiming at transient characteristics and steady-state characteristics of a single-phase earth fault in different grounding modes; according to the invention, when a line has a grounding fault in the use process, the power distribution line without a single-phase grounding fault is prevented from being powered off to cause interruption of normal power supply, so that the influence on the
