Redundant generic object oriented substation event (GOOSE) messages with live and test power system data

A method comprising:

• receiving, via a subscribing intelligent electronic device (IED), a first Generic Object Oriented Substation Event (GOOSE) message over a first GOOSE connection and a second GOOSE message over a second GOOSE connection, wherein the first GOOSE message comprises a live message associated with live power system data and the second GOOSE message comprises a test message associated with test power system data, wherein the first GOOSE message and the second GOOSE message comprise data corresponding to the same type or types of electrical protection logic signals;
• based on the first GOOSE message, performing, via the subscribing IED, a protective action comprising providing one or more control signals to trip a circuit breaker during a test;
• and
• based on the second GOOSE message, providing one or more test result signals to one or more testing devices during the test.

A method, comprising:

• receiving, via a subscribing IED, a first Generic Object Oriented Substation Event (GOOSE) message comprising live power system data, a second GOOSE message comprising test power system data, and a third GOOSE message comprising the live power system data, wherein the first GOOSE message and the third GOOSE message are received over a first GOOSE connection, and wherein the first GOOSE message and the second GOOSE message comprise data corresponding to the same type or types of electrical protection logic signals;
• based on the first GOOSE message, performing a protective action comprising providing one or more controls signals to trip a circuit breaker during a test;
• based on the second GOOSE message, providing one or more test result signals to one or more testing devices during the test;
• waiting to receive an expected fourth GOOSE message within a time period following receipt of the second GOOSE message, wherein the second GOOSE message was received over a second GOOSE connection, and wherein the expected fourth GOOSE message is expected to be received over the second GOOSE connection;
• and
• sending, via the subscribing IED, an alarm signal to an operator when a time delay between reception of the second GOOSE message and the expected fourth GOOSE message exceeds a preset time duration in the subscribing IED.
