A digital substation and a virtual loop remote self-checking method of a relay protection device thereof, the method comprising: selecting an operation and maintenance master station as a third party to participate in testing, and simulating a smart device or a bay layer device to generate a test message; the operation and maintenance master station sends the test message to the relay protection device, and sends a virtual loop test remote control command; after the relay protection device receives the test message file and receives the virtual loop test remote control command, a remote signaling change of the relay protection device is generated, and the relay protection device uploads the incoming state change to the operation and maintenance master station through a station control layer network for checking; a test result judgment comprises: the operation and maintenance master station obtains the relay protection device change signal through the station control layer network for checking, judges whether the incoming point number and the incoming change state meet the expectation, and forms the test result. The application realizes the rapid self-checking of the virtual loop function of the newly-built and reconstructed relay protection device in the digital substation, thereby improving the reliability and efficiency of the test.
