The C37.118 Master driver allows the simulator to connect to one or many Phasor Measurements Units (PMUs), typically operating as C37.118 Slaves to stream phasor data. The simulator connects with the PMU, requests the configuration and sends a command to begin the data transmission. The received data is available for computation and analysis within the simulation model. The C37.118 communication protocol has been implemented according to the IEEE Std C37.118.2-2011 standard. Three communication protocols are supported: TCP only, UDP only or TCP/UDP.
