Information

1. Purpose of model

Simple model of a cable with consideration of resistance and inductive reactance per unit length. Computes losses and voltage drop depend on typical cable types and specified length.

2. Level of detail, physical effects considered, and physical insight

L3E (defined in the CodingConventions) - Quasi-Stationary model of transmission line as a concentrated element. Active- and (inductive) reactive power (losses) are regarded. Cable capacitance is neglected. When checkbox simpleModel is activated: calculation based on nominal grid voltage instead of actual voltage at power ports.

3. Limits of validity

Limited by length due to neglecting of cable capacitance, esp. at medium and high voltage. When checkbox simpleModel is activated: limited by voltage drops of about 20 % of nominal grid voltage.

4. Interfaces

Two ApparentPowerPort for each terminal.
