Abstract :
This article presents a model to represent double three-phase transmission lines, including the frequency dependence of longitudinal parameters, achieved through phase/mode transformation. The proposed model uses a single real transformation matrix for the entire frequency range, 10 Hz to 10 kHz. The model includes the frequency dependence in digital programs, such as ATP and MICROTRAN, using ideal transformers. This model is applied to three types of line transposition and nontransposed line, called the quasi-mode transmission line model. It is employed for an actual double three-phase transmission line in MICROTRAN program. Some transient simulations are performed, such as energization and fault analysis
