Description

The Programmable Voltage Source (Three-Phase) block models a three-phase voltage source with programmable AC magnitude, frequency, and phase shift. Choose the external mode to specify these quantities by physical input signals M, F, and Phi. You can add harmonics and internal impedance to the voltage source.

For relevant equations, see the Voltage Source (Three-Phase) block.

Variables

Use the Variables settings to specify the priority and initial target values for the block variables before simulation. For more information, see Set Priority and Initial Target for Block Variables.
