NEPLAN RMS Calculation

The RMS calculation is available in two different simulation frames, DQ0 and ABC.

The RMS mode is used for transient stability or electromechanical simulation, where the electrical model quantities are described by their fundamental frequency components. The DQ0 mode can be used in case of balanced systems with balanced or unbalanced faults. RMS-DQ0 is the preferable solution for typical stability studies. The ABC mode however is more flexible and should be used in case of asymmetrical or unbalanced network conditions.
