A network topology-based method for analyzing power grid faults

Abstract

The application provides a network topology-based power grid fault analysis method, and relates to the technical field of fault analysis, comprising: in response to the selection of a monitoring node in a power grid topology digital space by an analysis terminal, taking the sensor data corresponding to the corresponding monitoring node as a drill data source, injecting the simulation fault value set by the analysis terminal, determining a plurality of fault influence areas based on the electrical position of the drill data source and the simulation fault value, remotely operating the power grid equipment in the fault influence areas, and obtaining the action feedback state of the power grid equipment; determining the load transfer device switching reserve line transfer access point according to the path planning strategy and the fault influence area, updating the power grid topology digital space in combination with the action feedback state, obtaining the fault treatment digital space, and sending the fault treatment digital space to the analysis terminal for display. The application adjusts the switching distance and the equivalent conversion of the remaining length of the cross-voltage level section, so that the arrangement of the transfer access point adapts to the power grid structure mixed with different voltage levels.
