Sequence Analyzer (Phasor)

Compute sequence components (positive, negative, and zero) of three-phase phasor signal

Library

Control and Measurements/Measurements

Description

The Sequence Analyzer (Phasor) block computes the three-sequence phasor components (positive sequence u1, negative sequence u2, and zero sequence u0) of a three-phase phasor signal as follows:

where is the complex operator performing a 2 rotation:

Dialog Box and Parameters

Sequence

Select the sequence components: Positive, Negative, Zero, or all three sequences Positive, Negative, and Zero.

Inputs and Outputs

abc

The three-phase phasor signal [ua ub uc].

mag u

Returns the magnitude of the selected sequence phasor component.

angle u

Returns the angle, in degrees, of the selected sequence phasor component.

Characteristics
