A three-phase wye-connected synchronous generator supplies a network through a transmission line. The network can be modeled as a voltage source with fixed voltage and frequency. The reason we can model the network like this is that it is "large" enough that it can absorb or deliver power while maintaining its voltage constant. A connection to a large network is often also called an "infinite bus" connection. In other words, the power that we exchange with the network is insignificant compared to the rating of the network and so it is virtually impossible for us to change the properties of the network. An intuitive analogy could be: if we pull a few small buckets of water out of the ocean, we are changing the amount of water in the ocean, but it is such an insignificant change as to be ignorable from the point-of-view of the ocean. The four-pole, 60 Hz generator ratings are 40 MVA and 26 kV with a 0.85 p.u. reactance. The field current of the generator can be adjusted to regulate the magnitude of the induced generator voltage between 0.65 to 1.5 times the rated voltage. The network voltage rating is 24 kV.
