eMTCoSim offers a hybrid simulation comprising EMT and phasor domains. This gives the best of both domains: the solution of larger networks with phasors and added fidelity where needed.
ETAP has developed accurate signal processing algorithms (waveform to phasor data conversion) to accurately map instantaneous EMT data as phasors. This conversion extracts the fundamental power components from the electromagnetic transient domain and injects them into the phasor domain resulting in a fast, easy-to-use, feature rich, and robust co-simulation solver.
