Overview
An advanced RT-LAB / ARTEMiS example using the IEEE 123-node distribution feeder to demonstrate Compensated Stublines and SSN-based network decoupling for real-time simulation.
This advanced example demonstrates the IEEE 123-node distribution feeder using ARTEMiS Compensated Stublines and SSN. Four Compensated Stublines are used to replace selected pi-lines and decouple the complete circuit into three independent sets of equations, each solved with SSN.
The original pi-lines replaced by Compensated Stublines have lengths between approximately 700 and 1000 ft. The replacement stublines use a one-time-step propagation delay and preserve the same total inductance, which corresponds to an equivalent line length of roughly 14 km at a 50 µs simulation time step. The Compensated Stubline technique is used to minimize the error that would otherwise be introduced by the increased equivalent capacitance of the stubline model.
