This file contains the definition for 4 types of lines, their configurations and the conductors associated with these lines.
The line is one of the major parts of the method used for solving a powerflow network. In essense the distribution network can be seen as a series of nodes and links. The links (or lines as in this file) do most of the work, solving a series of 3 dimensional matrices, while the nodes (defined in node.cpp) are containers and aggregators, storing the values to be used in the equation solvers.
In general, a line contains a configuration that contains a spacing object, and one or more conductor objects, exported as phaseA_conductor, phaseB_conductor, phaseC_conductor, and phaseN_conductor. The line spacing object hold information about the distances between each of the phase conductors, while the conductor objects contain the information on the specifics of the conductor (resistance, diameter, etc...)
Line itself is not exported, and cannot be used in a model. Instead one of 3 types of lines are exported for use in models; underground lines, overhead lines, and triplex (or secondary) lines. Underground lines and overhead lines use the basic line configuration and line spacing objects, but have different conductor classes defined for them. The overhead line conductor is the simplest of these with just a resistance and a geometric mean radius defined. The underground line conductor is more complex, due to the fact that each phase conductor may have its own neutral.
Triplex lines are the third type of line exported. A special triplex line configuration is also exported which presents 3 line conductors; l1_conductor, l2_conductor, and lN_conductor. Also exported is a general insulation thickness and the total diameter of the line. The conductor for triplex lines is much the same as the overhead line conductor.
All line objects export a phase property that is a set of phases and may be set using the bitwise or operator (A|B|C for a 3 phase line).
