AsynchronousMachineDynamics Class
Asynchronous machine whose behaviour is described by reference to a standard model expressed in either time constant reactance form or equivalent circuit form <font color="#0f0f0f">or by definition of a user-defined model.</font> Parameter details: <ol> <li>Asynchronous machine parameters such as <i>Xl, Xs,</i> etc. are actually used as inductances in the model, but are commonly referred to as reactances since, at nominal frequency, the PU values are the same. However, some references use the symbol <i>L</i> instead of <i>X</i>.</li> </ol>

Asynchronous machine whose dynamic behaviour is described by a user-defined model. |
| cim:AsynchronousMachineTimeConstantReactance |
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>). |
| cim: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: <i>Xs</i> = <i>Xm</i> + <i>Xl</i> <i>X'</i> = <i>Xl</i> + <i>Xm</i> x <i>Xlr1 </i>/ (<i>Xm </i>+ <i>Xlr1</i>) <i>X''</i> = <i>Xl</i> + <i>Xm</i> x <i>Xlr1</i> x <i>Xlr2</i> / (<i>Xm</i> x <i>Xlr1</i> + <i>Xm</i> x <i>Xlr2</i> + <i>Xlr1</i> x <i>Xlr2</i>) <i>T'o</i> = (<i>Xm</i> + <i>Xlr1</i>) / (<i>omega</i><i><sub>0</sub></i> x <i>Rr1</i>) <i>T''o</i> = (<i>Xm</i> x <i>Xlr1</i> + <i>Xm</i> x <i>Xlr2</i> + <i>Xlr1</i> x <i>Xlr2</i>) / (<i>omega</i><i><sub>0</sub></i> x <i>Rr2</i> x (<i>Xm</i> + <i>Xlr1</i>) 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). |
