Fault trip-out rapid studying and judging method for massive power grid signals

The invention provides a fault tripping rapid studying and judging method for massive power grid signals, and the method comprises the steps: building an equipment signal monitoring engine through a finite state machine in advance, and capturing a to-be-monitored signal of equipment in the massive power grid signals; obtaining D5000 system alarm information, obtaining measurement information of telemetering and telesignalling, and obtaining topological information of a PMS equipment management system interface; and the equipment signal monitoring engine is adopted to monitor equipment signals, and in combination with the D5000 system alarm information, the measurement information of the telemetering and telesignaling and the topological information of the PMS equipment management system interface, three types of accidents of line faults, main transformer faults and switch tripping are identified, and the power failure range is determined. According to the method, the fault tripping risk can be quickly identif
