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 to assign different IP addresses to each slave/outstation instance even if a single physical network interface (i.e., ethernet port) is used.
About IEEE C37.118
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.
