FAST DECOUPLED SIMULATION OF LARGE POWER ELECTRONIC SYSTEMS USING NEW2-PORT COMPANION LINK MODELS

Algorithms of novel two-port companion link models for fast decoupled simulation are presented, The link models enable a large circuit to be broken down into many small subcircuits for easy circuit formulation and fast simulation, The proposed link algorithms are demonstrated in a converter-fed de transmission system with a transmission-line length equivalent to 1000 km, Simulation and experimental results from a lab oratory setup have confirmed the validity of the link models, Proposed simulations are also found to be faster and more accurate than PSpice simulations in the example.
