  • Simscape / Electrical / Sources

  • Controlled Voltage Source (Three-Phase) block

Description

The Controlled Voltage Source (Three-Phase) block represents an ideal three-phase voltage source that maintains the specified voltage regardless of the current through it.

To choose the input type of this block, set the Input type parameter to Instantaneous or Sinusoidal magnitude and phase shift. If you select Instantaneous, this block works only in time simulation mode. If you select Sinusoidal magnitude and phase shift, this block works in both time and frequency-time simulation modes. For more information, see Frequency and Time Simulation Mode.

To access the implementation with an expanded, three-phase port, double-click the block and set the Modeling option parameter to Expanded three-phase ports.

Ports

Input

Parameters

expand all

Whether to model composite or expanded three-phase ports.

Composite three-phase ports represent three individual electrical conserving ports with a single block port. You can use composite three-phase ports to build models that correspond to single-line diagrams of three-phase electrical systems.

Expanded three-phase ports represent the individual phases of a three-phase system using three separate electrical conserving ports.

Type of physical signal input. Choose between:

  • Instantaneous — The output voltages, [va vb vc], are equal to the values of the input port S.

  • Sinusoidal magnitude and phase shift — The output voltages are equal to:

    va=(2Vt3)sin(2πFrated+ph)vb=(2Vt3)sin(2πFrated+ph2π3)vc=(2Vt3)sin(2πFrated+ph+2π3)

Rated electrical frequency. The value of this parameter must be equal to the value of the rated electrical frequencies of other sinusoidal sources in your model, if present.

Dependencies

To enable this parameter, set Input type to Sinusoidal magnitude and phase shift.
