Automated Real-Time Simulator Testing of Protection Relays

This paper describes the results of a project to develop a proof-of-principle working example of automated hardware-in-loop testing of protection schemes on an RTDS real-time simulator. The paper describes the test system configured to demonstrate automated closed-loop testing of the relays in a simple protection scheme, and presents the results of a typical set of such tests. The development of the script file to automate the tests is also discussed.
