Examples
There are three types of source control modes for the Voltage Source Model 1: Fixed, External and Auto.
Fixed Control: The magnitude, frequency and phase angle of the voltage source are specified internally through Source Values for Fixed Control Dialogs. The base voltage and base frequency specified in the Configuration Dialog are not meant for controlling.
External Control: This option provides external input connections for specifying magnitude, frequency and phase values. You can connect a slider to this input for a convenient runtime manual adjustment, or use a control system output for dynamic adjustment. The external input signals must be in the following units:
Magnitude: kV, Line to Line, RMS
Frequency: Hz
Phase Angle: Degrees or radians, depending on the External Phase Input Unit setting in the Configuration dialog.
Auto Control (3-Phase Only): In this mode, the voltage magnitude can be adjusted automatically so as to regulate the voltage at a selected bus and/or adjust the source phase angle internally to regulate the real power leaving the source. The following diagram shows how the source is connected to allow automatic voltage control:
Configuration: Source Control | Auto and Enable Automatic Voltage Control? | Yes
