Class: AsynchronousMachineEquivalentCircuit
The electrical equations of all variations of the asynchronous model are based on the AsynchronousEquivalentCircuit diagram for the direct- and quadrature- axes, with two equivalent rotor windings in each axis.
_Equations for conversion between equivalent circuit and time constant reactance forms: _
_Xs = Xm + Xl _
_X' = Xl + Xm x Xlr1 / (Xm + Xlr1) _
_X'' = Xl + Xm x Xlr1 x Xlr2 / (Xm x Xlr1 + Xm x Xlr2 + Xlr1 x Xlr2) _
_T'o = (Xm + Xlr1) / (omega0 x Rr1) _
_T''o = (Xm x Xlr1 + Xm x Xlr2 + Xlr1 x Xlr2) / (omega0 x Rr2 x (Xm + Xlr1) _
_Same equations using CIM attributes from AsynchronousMachineTimeConstantReactance class on left of "=" and AsynchronousMachineEquivalentCircuit class on right (except as noted): _
_xs = xm + RotatingMachineDynamics.statorLeakageReactance _
_xp = RotatingMachineDynamics.statorLeakageReactance + xm x xlr1 / (xm + xlr1) _
_xpp = RotatingMachineDynamics.statorLeakageReactance + xm x xlr1 x xlr2 / (xm x xlr1 + xm x xlr2 + xlr1 x xlr2) _
_tpo = (xm + xlr1) / (2 x pi x nominal frequency x rr1) _
tppo = (xm x xlr1 + xm x xlr2 + xlr1 x xlr2) / (2 x pi x nominal frequency x rr2 x (xm + xlr1).

constant that, when multiplied by the angular velocity of the rotor poles with
respect to the magnetic field (frequency), results in the damping torque. This
value is often zero when the sources of damping torques (generator damper windings,
load damping effects, etc.) are modelled in detail. Typical value = 0.

MW x s. For a motor, it includes the motor plus its mechanical load. Conventional
units are PU on the generator MVA base, usually expressed as MW x s / MVA or
just s. This value is used in the accelerating power reference frame for operator
training simulator solutions. Typical value = 3.
