This video shows you how to get started working with Digital Twin in RelaySimTest.

It shows a test of the auto-reclosure (ARC) function with RelaySimTest and the Siemens SIPROTEC DigitalTwin and how an existing test plan for a physical protection system can be converted into a test plan for a virtual protection system by simply adding a Digital Twin connection that assigns all protection devices in the topology to the Digital Twin. If you want to test your physical protection system later, you only need to deactivate the Digital Twin connection and perform the test with your conventional test setup.

In RelaySimTest, clear instructions guide you through the process of setting up the test with the SIPROTEC DigitalTwin, including logging into the Siemens Digital Twin environment, importing the SIM files of selected devices generated by DIGSI, uploading the state sequence XML file with the
definition of analog and binary signals, and how to copy the API password to start the test.

As a protection tester, you can now validate your protection system before installing it – by testing with digital twins of protection relays. Digital twins come with many advantages: you do not need any spare IEDs for testing, you have no output power limitations, And you can use an unlimited number of virtual test signals.

With RelaySimTest you can test your protection system effectively and efficiently with digital twins. You can simulate your power system and adapt
this simulation iteratively corresponding to the Trip and Close commands. You can simulate real power system scenarios, replay them on your
virtual protection system and evaluate its behavior. Later, you can reuse your test plan for testing your physical protection system.

The job that you as a protection tester must accomplish usually consists of testing
- protection function parameters and settings,
- individual protection functions,
- complete relays including logic and coordination between protection functions,
- and whole protection systems, including distributed systems.

For these tasks you need to inject steady state signals for a simplified representation of prefault, fault and postfault states, and transient signals for a realistic representation of the evolution of electrical quantities in the power grid. The best way to accomplish these tasks is with two complementary testing approaches and the appropriate pieces of software that we offer: Test Universe and RelaySimTest.

Always use the right tool for the right task to get the most benefit from their strengths. Test Universe focuses on protection functions and verifies accuracy, characteristics, and other settings. RelaySimTest is based on the electric power system for testing the entire protection system, including the simulation of connected CTs and VTs and the interaction with breakers and other IEDs.

Test Universe is based on the relay and its settings and RelaySimTest is based on the power system, or the relevant part thereof.

Test plans include an automatic assessment of relay responses to prefault, fault and postfault states in Test Universe, and a realistic simulation of events in the power grid in RelaySimTest. And the really great thing about RelaySimTest is it allows you to find out if your protection system, with its current settings, actually protects the power grid reliably.

Throughout the protection lifecycle, the combination of these tools enables you to validate your protection system efficiently and with maximum testing quality - in conventional, hybrid and digital substations.

The most important change is the addition of a digital twin connection for testing with a Siemens SIPROTEC DigitalTwin.

Watch this video to see how simple it is to convert a test document from testing with physical to virtual IEDs and vice versa and how RelaySimTest responds to the IEDs actions using its patented Iterative Closed Loop feature.

With software version 4.10, we have improved RelaySimTest in several ways.

The two most important changes include the addition of a new simulation model for an induction motor (or asynchronous motor) and the possibility to simulate infeed events.

With these major additions, you can now test Motor Bus Transfer schemes, Motor protection, or Rate of Change of Frequency (ROCOF) protection using the system-based testing approach.

Besides these big changes, a number of smaller improvements have also been made, including improvements of the Interactive System Simulation and the capabilities of RelaySimTest in terms of testing IEC 61850 protection systems.

RelaySimTest is a software solution for system-based protection testing with OMICRON test equipment that takes a novel, future-oriented approach: the test is independent of relay type and relay manufacturer and the often very extensive parameter settings. Instead, it completely focuses on the correct behavior of the protection system. This is made possible by simulating realistic events in the power system.

RelaySimTest is a software solution for system-based protection testing with OMICRON test equipment. The test approach is independent of relay type, manufacturer, and parameter settings. Instead, RelaySimTest completely focuses on the correct behavior of the protection system by simulating realistic power system events.

The Interactive System Simulation is a completely new test case type, which is available to all RelaySimTest customers with a CMC test set with NET-2 interface or an ARCO 400. No additional license is required. Like the Test Universe module QuickCMC, the Interactive System Simulation can continuously output the current state of the power system simulation. By changing settings, breaker and disconnector positions and adding faults, the output values will change throughout execution. Trip and close commands from the IEDs will also be integrated as breaker open and close events in non-real time.

Like Quick CMC the Interactive System Simulation is a Swiss army knife in your system-based testing workflow. Some of the potential applications we anticipate:
• Wiring, metering, and functional checks especially in setups with multiple test sets
• Training facilities where technicians are trained to operate IEDs under realistic system conditions
• Testing of long running restoration schemes
• Providing realistic system conditions for resilience testing of PAC systems under cyber attacks
