Initialize Synchronous Machines and Controllers

In Simscape™ Electrical™ software, you can specify steady-state power and voltage values for a synchronous machine. Based on the values you specify, the machine block calculates the initial field circuit and rotational input values required to achieve this steady state. Starting a machine at steady state prevents undesired transient effects in your simulation.

Calculate the required power and voltage characteristics of your load circuit.
In the Initial Conditions tab of the dialog box, set Specify initialization by to Electrical power and voltage output.
Enter the required power and voltage values and click OK.
Right-click the machine block and select Electrical > Display Associated Initial Conditions.
Simscape Electrical Power Systems calculates the field circuit and rotational port values required to start the machine in steady state and displays them in the MATLAB^® Command Window.
Use these values to input parameters to the blocks connected to the field circuit and rotational ports of the synchronous machine.

Note

If you set Specify initialization by to Mechanical and magnetic states, Simulink^® does not calculate the associated initial conditions fro the machine.
