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.
Co-simulation is the cooperative simulation of a system model through different software packages. Collaborative simulation, as such, spans more physics domains and offers more insight than single-domain engines alone. Therefore, the collective composition of its parts enables multi-domain, multi-physics simulation results. ETAP CoSim™ enables ETAP simulation engines to collaborate and interact. For example, the ETAP Time Domain Power Flow can co-simulate with ETAP Harmonic Analysis to assess harmonics distortion over time. ETAP CoSim platform also enables ETAP and 3rd party tools to co-simulate and solve large, complex, and multi-disciplinary system models—collectively via an efficient API surface. The ability to co-simulate with third-party software extends existing software capabilities into the multi-physics domain and greater situational awareness. This solution presentation will introduce the concepts of co-simulation and the flexible ETAP CoSim platform. The presentation will also highlight commercial use-cases of Phasor and Electromagnetic co-simulation using emtCoSim™ and Controller Hardware-in-the-Loop (CHIL).
Learn how ETAP Transient Stability program and Electromagnetic Transients Program (eMT) are combined in eMTCoSim mode to provide hybrid simulations of Phasor and Transients domains to collectively solve large, complex, and multi-disciplinary system models with higher fidelity.
