OPAL-RT supports IEC 61850 interfaces to connect to various IEDs via the publishing and subscribing of GOOSE and Sampled Values messages. Using a standard network interface card, this protocol can be easily and rapidly integrated into any simulation model. With the proper user configuration, a driver is initialized on the target simulator at the start of the simulation and begins publishing and subscribing to other IEDs. The IEC 61850 driver makes use of asynchronous threads on dedicated cores in order to achieve high performance.
OPAL-RT supports IEC 61850-9-2LE Sampled Values, as well as Samples Values based on a Substation Configuration Language (SCL) file (IEC 61869-9). Simulators can be used to emulate merging unit or to receive data from real merging unit. GPS time synchronization is performed using IEEE 1588, IRIG-B or 1PPS input signals using an optional time synchronization card (see table below). A complete error injection mechanism is also available for IEC 61850-9-2 (Part number: OP3252) to emulate cyber-security attacks on the network or erroneous transmission.
