The C37.118 master I/O interface allows connecting to one or many Phasors Measurements Units (PMUs) which are typically operating as C37.118 slaves to stream phasor data. 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.
With the proper user configuration, a driver is initialized on the target simulator at the start of the simulation and connects with all configured PMUs, requesting the configuration and sending a command to begin data transmission. The received data is available for computation and analysis within the simulation model. Three communication protocols are currently supported: TCP only, UDP only or TCP/UDP. It is the user's responsibility to select the communication protocol that matches the PMUs configuration. More details can be found in Annex F of the IEEE Std C37.118-2-2011 document.
Data transferred from the master driver to the model includes phasor data, analog data, digital data, frequency deviation from nominal frequency, the frequency rate of change and timestamp.
Communications protocols can be configured in the I/O Interface Configuration tool that can be opened from HYPERSIM Ribbon Options.
