AsynchronousMachineTimeConstantReactance

Class Description

Parameter details: <ol> <li>If <i>X'' </i>=<i> X'</i>, a single cage (one equivalent rotor winding per axis) is modelled.</li> <li>The “<i>p</i>” in the attribute names is a substitution for a “prime” in the usual parameter notation, e.g. <i>tpo</i> refers to <i>T'o</i>.</li> </ol> The parameters used for models expressed in time constant reactance form include:

• RotatingMachine.ratedS (<i>MVAbase</i>);
• RotatingMachineDynamics.damping (<i>D</i>);
• RotatingMachineDynamics.inertia (<i>H</i>);
• RotatingMachineDynamics.saturationFactor (<i>S1</i>);
• RotatingMachineDynamics.saturationFactor120 (<i>S12</i>);
• RotatingMachineDynamics.statorLeakageReactance (<i>Xl</i>);
• RotatingMachineDynamics.statorResistance (<i>Rs</i>);
• .xs (<i>Xs</i>);
• .xp (<i>X'</i>);
• .xpp (<i>X''</i>);
• .tpo (<i>T'o</i>);
• .tppo (<i>T''o</i>).
