Protection Systems with IEC 61850
The IEC 61850 standard forms the basis for communication in electrical substations and enables new approaches like system digitalization.
In Digital Substations, different communication services are present: power system quantities are conveyed via Sampled Values and the devices exchange their statuses via GOOSE messages. Signaling to the SCADA system happens via Client/Server communication (MMS).
Our protection testing solutions for Digital Substations connect to the devices under test with these protocols. Testing is performed as established with conventional protection relays.

Protection Testing with GOOSE
GOOSE messaging is widely used for real-time communication of status information within Digital Substations. With our CMC test sets and Test Universe software, you efficiently test protection relays based on GOOSE communication.

Protection Testing with Client/Server Communication (MMS)
In Digital Substations, Client/Server communication is used for information exchange between SCADA and IEDs. Our CMC test sets and Test Universe software check the IEDs with all their attributes, verify correct signaling, and reveal all Client/Server events on the network.

Protection Testing with Sampled Values
Sampled Values represent current and voltage values of the electrical power system within the network of Digital Substations. Our CMC test sets and Test Universe software simulate these power system quantities to test protection devices in accordance with the IEC 61869-9 standard.

System-Based Protection Testing in IEC 61850 Substations
Complex protection scenarios in Digital Substations are most efficiently tested with a system-based approach. With RelaySimTest, one CMC test set imitates up to four merging units to simulate realistic events in the power system and detects hidden errors in the settings, logic, and design of the protection system.
