modelPIline
PI transmission line, 3-phase dq0
Extends from Ports.Port_p_n (AC two port, 3-phase), Partials.LineBase (PI- and T-line base, 3-phase dq0).
Information
Transmission line modelled as discretised telegraph-equation, 'π-elements'.
The line of total length len is divided into elements of length delta = len/ne.
It is composed of ne interior elements of length delta. Therefore it contains ne+1 nodes. Each element corresponds to a series resistor-inductor with values R and L corresponding to its length. A shunt parallel capacitor-conductor is linked to each node.
The minimum of ne is 1.
