1 Symmetrical Component Transform

Function File: V0, V1, V2 = symmetrical (Vabc)

Symmetrical component transform: converts phase voltages (Va, Vb, Vc) into sequence components (V0, V1, V2).

1.1 Description

This function applies the forward symmetrical component transformation using the operator a = exp(j*2*pi/3).

1.2 Inputs

1.3 Outputs

1.4 Example

Vabc = [1; 0; -1];
[V0, V1, V2] = symmetrical(Vabc);

2 Inverse Symmetrical Component Transform

Function File: Vabc = inv_symmetrical (V0, V1, V2)

Inverse symmetrical component transform: converts sequence components (V0, V1, V2) back into phase voltages (Va, Vb, Vc).

2.1 Description

This function applies the inverse symmetrical component transformation using the operator a = exp(j*2*pi/3).

2.2 Inputs

2.3 Output

2.4 Example

V0 = 0; V1 = 1; V2 = -0.5;
Vabc = inv_symmetrical(V0, V1, V2);
