Single real transformation matrix application for asymmetrical three-phase line transient analyses
(2008-12-01)
Single real transformation matrices can change the Z and Y matrices into diagonal ones for transposed three-phase lines. Considering non-transposed non-symmetrical three-phase lines, the errors between the Clarke's matrix ...
Correction procedure applied to a single real transformation matrix -Untransposed three-phase transmission line cases
(2006-12-01)
Clarke's matrix has been used as an eigenvector matrix for transposed three-phase transmission lines and it can be applied as a phase-mode transformation matrix for transposed cases. Considering untransposed three-phase ...
