Description

The Line Voltage Sensor (Three-Phase) block represents an ideal three-phase line voltage sensor. The block measures the line-line voltages of a three-phase system and outputs a three-element physical signal vector. Each element of the physical signal output vector is proportional to the voltage between the phases as follows:

• Element 1: V_ab = V_a - V_b

• Element 2: V_bc = V_b - V_c

• Element 3: V_ca = V_c - V_a

where V_a, V_b, and V_c are the absolute a-, b-, and c-phase voltages.

Note

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

Ports

Output

V — Three-elements vector

physical signal

Three-element physical signal vector output port associated with the voltages between the phases

Conserving

Parameters

Modeling option — Whether to model composite or expanded three-phase ports

Composite three-phase ports (default) | Expanded three-phase ports

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.
