Fault diagnosis and positioning method for tripping and closing monitoring

The embodiment of the invention provides a fault diagnosis and positioning method for tripping and closing monitoring, and belongs to the technical field of power grids. The fault diagnosis and positioning method comprises the steps of judging whether a protection device starting signal is received or not; when it is judged that the protection device starting signal is received, obtaining an action MMS signal; judging whether the action MMS signal is received or not; and under the condition of judging that the action MMS signal is received, acquiring a tripping and closing GOOSE signal. The invention provides a fault diagnosis and positioning method for tripping and closing monitoring. A tripping and closing GOOSE signal, an intelligent terminal tripping and closing reverse correction GOOSE signal, a recovery confirmation signal and a circuit breaker position GOOSE signal are monitored through a tripping and closing monitoring reference template, and the fault diagnosis and positioning are carried out through
