OPAL-RT's C37.118 slave I/O interface allows instantiating multiple C37.118 slave sessions that can be used to report data to a C37.118 master, which is typically a PDC (Phasor Data Concentrator). It has been implemented according to the IEEE Std C37.118.2-2011 standard. Using a standard network interface card, this protocol can be easily and rapidly integrated into any simulation model. This driver provides an asynchronous TCP/IP communication interface and an IP aliasing mechanism, allowing assigning different IP addresses to each slave/outstation instance even if a single physical network interface (i.e., Ethernet port) is used. |

C37.118 is the IEEE Standard for Synchrophasor Measurements for Power Systems, which defines synchrophasors, frequency, and rate of change of frequency (ROCOF) measurement under all operating conditions. It specifies methods for evaluating these measurements and requirements for compliance with the standard under both steady-state and dynamic conditions. |

Product Selection Guide
C37.118 Slave requires software license OP3271, which comes with 50 data points. Visit this page more information on data points.
If additional data points are required, then they may be added via product OP3050.
Since real-time simulators come with one available Ethernet port, if additional physical Ethernet ports are required on the real-time simulator, these can be added via a kit.
Note that for applications requiring many Ethernet ports,the OP4510 and OP4512 simulators are not recommended.
C37.118 Slave can be added to real-time simulators without the need for additional hardware.
A time synchronization module to maintain high-precision sync and time-stamping may be required depending on the application. For more information on precision timing, please this page: Precision Timing Synchronization.
