SSN simulation of a WideBand Line Model (With Full Phase Domain Fitting of Frequency Dependent Parameters)

Abstract

The circuit shows the capability of ARTEMiS-SSN solver to make the real-time simulation of a WideBand line model within Simulink and SimPowerSystems. In the demo, a 25 km 3-ph cable (equivalent to 6 phase line considering the sheath) is energized with an open end. The sheath is grounded with 10 Ohms resistors at both ends. See the ‘Demo Validation against EMTP-RV’ section at the end of this document for more information on this test case. The WD-line model was fitted with a total of 14 poles for the characteristic admittance Yc(w) and 36 for the 6 propagation functions H1(w) to H6(w). Real-time simulation with 2 cores of a 3.3 MHz i7 Intel target (one core for each end of the line) shows that this line can be simulated at a 25 microseconds time-step.
