Three-Phase Synchronous Machine Control

This example shows how to control and initialize a Synchronous Machine (SM). The test circuit shows the SM operating as a generator. The terminal voltage is controlled using an AVR and the speed is controlled using a governor.

To view the SM machine base values and initial conditions, right-click the Synchronous Machine Round Rotor (standard) block and select 'Electrical' and then 'Display Base Values', 'Display Associated Base Values', or 'Display Associated Initial Conditions'. The overall model is initialized to start in periodic steady state to supply a load of 250 MW/15 Mvar.
