Description

The Phase Voltage Sensor (Three-Phase) block represents an ideal three-phase voltage sensor. It measures the voltages across the three-phase ports ~1 and ~2 and outputs a single three-element, physical signal vector. Each element of the physical signal output vector is equal to the voltage in the respective phase.

Note

You must connect the Phase Voltage Sensor (Three-Phase) block in shunt or in parallel with the three-phase element. For more information on how to use this block, see Build and Simulate Composite and Expanded Three-Phase Models.

Examples

Three-Phase Bridge Cycloconverter

Three-Phase Bridge Cycloconverter

A three-phase bridge cycloconverter. The cycloconverter consists of 36 thyristors and has the capacity to lower the frequency of the input voltage. The Control subsystem implements the cycloconverter RMS voltage control. It also provides pulse generation for the firing of the thyristors. The Visualization subsystem contains scopes that allow you to see the simulation results. The simulation time, t, is 1 second. The load increases when Load1 switches on at t = 0.75 seconds.

Parameters

Since R2026a

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.

Programmatic Use

To set the block parameter value programmatically, use the set_param function.

Parameter: port_option
Values: "ee.enum.threePhasePort.composite" (default) | "ee.enum.threePhasePort.expanded"

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"ee_lib/Sensors & Transducers/Phase Voltage Sensor (Three-Phase)"

Example: add_block("ee_lib/Sensors & Transducers/Phase Voltage Sensor (Three-Phase)","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
