/Physical Modeling/Electrical/Passive/Lines/Double-Circuit Transmission Line
Description
Block Double-Circuit Transmission Line simulates two parallel three-phase lines (including double-circuit ones), represented by a U-shaped substitution scheme with concentrated parameters, with the possibility of modeling zero-sequence communication between them. The model of each line takes into account phase active resistances, intrinsic phase inductors, mutual active resistances and inductors between phases, capacitances between phases, capacitances between phases and ground.
Regardless of the assignment method, matrices will be generated in the model , , , which describe three-phase lines and the connection between them:
Values with indexes and These are the intrinsic and mutual active resistances, inductors, and capacitances of lines 1 and 2.
Values with an index — these are mutual active resistances, inductors, capacitances between the phases of one line and the phases of another line. It is accepted that each phase of one line has the same effect on any phase of the other line.
Information about the parameters of the lines, such as mutual inductance, mutual active resistance, formulas for the ratio between natural and mutual values with values of the direct and zero sequence are given in the documentation for the blocks. Coupled Lines (Three-Phase) and Transmission Line (Three-Phase).
Variables
Use the parameter group Initial Targets to set the priority and initial target values for the block parameter variables before modeling. For more information, see Configuring physical blocks using target values.
Three-phase electrical port, corresponds to the negative terminals of the second line.
