AsynchronousMachineTimeConstantReactance

Class Description

Parameter details:

  1. If X'' = X', a single cage (one equivalent rotor winding per axis) is modelled.
  2. The “p” in the attribute names is a substitution for a “prime” in the usual parameter notation, e.g. tpo refers to T'o.
The parameters used for models expressed in time constant reactance form include: - RotatingMachine.ratedS (MVAbase); - RotatingMachineDynamics.damping (D); - RotatingMachineDynamics.inertia (H); - RotatingMachineDynamics.saturationFactor (S1); - RotatingMachineDynamics.saturationFactor120 (S12); - RotatingMachineDynamics.statorLeakageReactance (Xl); - RotatingMachineDynamics.statorResistance (Rs); - .xs (Xs); - .xp (X'); - .xpp (X''); - .tpo (T'o); - .tppo (T''o).

Attributes

Name Type Description
tpo Seconds Transient rotor time constant (T’o) (> AsynchronousMachineTimeConstantReactance.tppo). Typical value = 5.
tppo Seconds Subtransient rotor time constant (T'‘o) (> 0). Typical value = 0,03.
xp PU Transient reactance (unsaturated) (X’) (>= AsynchronousMachineTimeConstantReactance.xpp). Typical value = 0,5.
xpp PU Subtransient reactance (unsaturated) (X'') (> RotatingMachineDynamics.statorLeakageReactance). Typical value = 0,2.
xs PU Synchronous reactance (Xs) (>= AsynchronousMachineTimeConstantReactance.xp). Typical value = 1,8.
