Method for overhauling GOOSE in digital substation

The invention discloses a method for overhauling a GOOSE in a digital substation, relating to a method for overhauling a digital substation. Since the devices in the traditional substation transmit signals by hardwiring, the overhauling method thereof is not suitable for the digital substation. The method of the invention comprises: a GOOSE sender device is connected with a GOOSE receiver device through a network; the overhauling state of the sender device is detected, and the overhauling state information of the sender device is loaded into the test bit of a GOOSE message; the receiver device receives the GOOSE message transmitted by the network, analyzes the test bit in the message to obtain the overhauling state of the sender device, simultaneously detects the overhauling state thereof, and compares the overhauling state thereof with the overhauling state of the sender device; if the overhauling states of the receiver device and the sender device are consistent, the GOOSE data are judged to be valid data; and if not, the GOOSE data are judged to be invalid data. The invention has the advantages that the GOOSE network connection is not needed to be disconnected, the GOOSE message sent thereby does not influence devices which operate normally, and the function overhauling and debugging of the device GOOSE in the digital substation can be flexibly and reliably finished.
