IEC 61850-9-2 Sampled Values
Our IEC 61850 interface connects seamlessly to various IEDs, supporting the publishing and subscribing of GOOSE and Sampled Values messages. Using a standard network interface card, this protocol integrates quickly into any simulation model. With proper configuration, the driver initializes on the target simulator at the start of the simulation, establishing instant communication with other IEDs. To maintain high performance, the IEC 61850 driver operates with asynchronous threads on dedicated cores.

We support IEC 61850-9-2LE Sampled Values and IEC 61850 Sampled Values formats, as well as Sampled Values based on Substation Configuration Language (SCL) files (IEC 61869-9). Simulators can emulate a merging unit or receive data from a real merging unit, allowing full support for Sample Values IEC 61850 use cases. GPS time synchronization is available through IEEE 1588, IRIG-B, or 1PPS signals using an optional time synchronization card (see table below). An error injection mechanism for IEC 61850-9-2 (Part number: OP3252) is also available, allowing emulation of cyberattacks or transmission errors.

About IEC 61850
IEC 61850 is a standard for designing electrical substation automation systems, enabling rapid communication of events (GOOSE) and data samples (Sampled Values) over Ethernet frames. Built on Substation Configuration Language (SCL), this standard provides consistent naming and object modeling for data exchange at both device and substation levels. Sampled Values allow fast transmission of voltages, currents, and status information between transformers, transducers (CT, PT), and primary power system equipment.

FAQ
Find the answer to your questions
What are IEC 61850 Sampled Values and how do they work in real-time simulation?
EC 61850 Sampled Values are data messages used to transmit analog measurements like current and voltage in substations. Our IEC 61850-9-2 interface allows real-time publishing and subscribing of these Sample Values using standard network interface cards, enabling integration into any simulation model.
Does OPAL-RT support IEC 61850-9-2LE and other IEC 61850 Sampled Values formats?
Yes, we support IEC 61850-9-2LE Sampled Values and Sampled Values IEC 61850 formats based on Substation Configuration Language (SCL) files, including those aligned with IEC 61869-9 standards. This ensures flexibility for different substation configurations.
How can simulators emulate merging units using IEC 61850 9-2?
Using the IEC 61850-9-2 driver, our simulators can emulate a merging unit or receive Sampled Values IEC 61850 data from a physical merging unit. This supports advanced substation testing and validation within real-time simulation environments.
What role does substation configuration language play in IEC 61850 Sampled Values integration?
Substation Configuration Language (SCL) defines consistent naming and object models, essential for integrating IEC 61850 Sampled Values in simulations. We use SCL files to streamline the configuration and ensure accurate data exchange in virtual substations.
Is error injection available for IEC 61850 Part 9 LE simulations?
Yes, we offer an error injection mechanism (Part number: OP3252) for IEC 61850 Part 9 LE testing. This feature enables emulation of cyberattacks or transmission errors, enhancing the reliability and robustness of Sample Values IEC 61850 simulations.
