Description
Block Bergeron Line (Three-Phase) simulates a three-phase power transmission line using the traveling wave method, taking into account the finite propagation time of an electromagnetic wave between the ends of the line. The line is modeled in Clark coordinates and is set by the length and linear parameters of the forward and zero sequences.
In contrast to the focused RLC model, Bergeron Line (Three-Phase) It takes into account the propagation delay between the ends of the line, which makes it possible to reproduce the dynamics of extended lines and the associated electromagnetic transients.
A specialized block is used to divide the power system model into parallel computing segments. Connector Bergeron Line (Three-Phase).
