The invention discloses a statistics and display method for the accuracy of busbar small current grounding open line sequences. Specifically, a busbar small current grounding monitoring table is addedunder the SCADA application of an OPEN3000 system of a dispatching master station, and all busbars needing to be monitored are defined in the table; a busbar grounding open line result analysis tableis deployed on the OPEN3000 system side of the dispatching master station, and the table is a three-area synchronous table; a busbar small current interface program is deployed under an SCADA serverto perform grounding line judgment; grounding lines are searched for, busbar grounding open line results are subjected to statistics, and the busbar grounding open line result analysis table is updated; and when busbar grounding is restored, accuracy statistics when the grounding lines correspond to different sequences is carried out. According to the method, an original statistics and display mode for the accuracy of suspicious grounding open line sequences is broken through; the after-event analysis is facilitated by storing the open line results in the specific table; and the display is performed in a webpage form, so that the analysis and positioning by a monitor are facilitated.
