Improve power system performance in critical applications, validate protective relay performance, and optimize relay settings at our model power system testing laboratory. SEL will create a Real Time Digital Simulator (RTDS) model of your power system, distributed energy resources (DERs), and loads. Protective relays are then physically wired to the RTDS to simulate realistic conditions. This system allows us to test over 1,000 fault cases in less than 24 hours. This level of testing provides the equivalent of many years of operating history.
Thank you, SEL team, for the successful RTDS testing. It turned out better than expected, identifying and fixing several relay setting problems on four 500 kV lines faster than we anticipated.
