Connector Bergeron Line (Three-Phase)

Block Connector 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.

The block allows you to divide the model of the power system into parallel calculated segments. To do this, copy the block and connect the two blocks together using the external blocks Unit Delay with a delay equal to the simulation step.

When data is exchanged between parallel calculated segments, there is naturally a delay of one calculation step. If the physical propagation time of the wave along the line is not less than the simulation step, Connector Bergeron Line (Three-Phase) allows you to accurately account for this delay as part of the line dynamics. Due to this, dividing the network into computing segments does not create additional artificial delays and does not change the simulated electromagnetic processes.

In contrast to the focused RLC model, Connector 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.

If it is necessary to take into account the physical properties of the model, but the division into parallel calculated sections is not required, it is enough to use the block Bergeron Line (Three-Phase).
