SSN Simulation of a Frequency Dependent Parameter Line (Marti-type)

Abstract

The circuit shows the capability of ARTEMiS-SSN solver to make the real-time simulation of a FD-line (Marti type) within Simulink and SimPowerSystems. In the demo, a 200 km line is energized with an unbalanced RL load (at the end of phase C). The RL load disconnects at 0.2 sec. The FD-line model has 3 modes that are fitted with a total of 11 poles for the characteristic admittance Yc and 6 for the propagation function H. Real-time simulation with 2 cores of a 2.4 i7 Intel target (one core for each end of the line) shows that this line can be simulated at a 6 microseconds time-step with 11+6 poles (Yc and H) and 7 microseconds with 39+67 poles (Yc and H).
