Visual realization method of second safety defense line on-line monitoring of electric power system

The invention discloses a visual realization method of second safety defense line on-line monitoring of an electric power system and aims at solving the problems that operation state real-time monitoring results of a region stable control system is not visual, and the analysis is inconvenient. The configuration of a second safety defense line of the electric power system and the key information such as the communication state, the control mode, the key fault, the control quantity and the like of the control system in the current operation state are provided for dispatching operation personnel in a layered correlation visual display mode, the dispatch operation personnel can fast know the communication state and the control mode of the region stable control system, the maximum control cost value in the current operation state of the electric network, the key fault, the electric network safe stability after the control and the like only through observing the geographical wiring patterns of the electric power system or icons in different shapes and different colors on the stable control system layered structure patterns and numbers for representing the control quantity. The comprehensiveness of the on-line monitoring of the second safety defense line is ensured, and the on-line monitoring pressure of the dispatching operation personnel is obviously reduced.
