NEPLAN EMT Calculation
The EMT calculation is available in two different simulation frames, DQ0 and ABC.
The EMT mode is used for fast electromagnetic transient simulation, where the electrical model quantities are described by their instantaneous values. The ABC mode is more flexible and can be used in case of asymmetrical or unbalanced network conditions. EMT-ABC is the preferable solution for inrush currents and switching studies. The DQ0 mode can be used in case of balanced systems with balanced or unbalanced faults.
