The document discusses challenges in protection relay testing for future power grids. It summarizes a presentation given by Etienne Leduc on using real-time simulators for complex protection relay testing scenarios that are difficult to test with traditional approaches. The presentation covered how real-time simulators can provide closed-loop testing of detailed electromagnetic transient models, complex protection schemes, and the effect of relays on the grid. It also provided an overview of OPAL-RT's protection testing solutions including software, hardware, and services.

Recorded data from field Limitations
• Open loop
• Fixed V/I and ramp up
• No data alteration/loss
This is a good and proven method for
most “traditional” and “easy” cases
