Hi, I need to make a classical simulation of synchronous machine conected to an infinite bus. I´m using the simulink model of synchronous machine (pu), my problem is how to simulate the infinite bus. At first sight I thought that was simply put an eletrical source, but is not working once the terminal voltage of infinite bus (eletrical source) is not constant.
Best regards.

Hint: The characteristic of an infinte bus is its unlimited power capability and thus represents a voltage source with zero internal impedance.
