SynchronousMachineTimeConstantReactance
Synchronous machine detailed modelling types are defined by the combination of the attributes SynchronousMachineTimeConstantReactance.modelType and SynchronousMachineTimeConstantReactance.rotorType. Parameter details: The “p” in the time-related attribute names is a substitution for a “prime” in the usual parameter notation, e.g. tpdo refers to T'do. 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); - SynchronousMachineTimeConstantReactance.ks (Ks); - SynchronousMachineDetailed.saturationFactorQAxis (S1q); - SynchronousMachineDetailed.saturationFactor120QAxis (S12q); - SynchronousMachineDetailed.efdBaseRatio; - SynchronousMachineDetailed.ifdBaseType; - .xDirectSync (Xd); - .xDirectTrans (X'd); - .xDirectSubtrans (X''d); - .xQuadSync (Xq); - .xQuadTrans (X'q); - .xQuadSubtrans (X''q); - .tpdo (T'do); - .tppdo (T''do); - .tpqo (T'qo); - .tppqo (T''qo); - .tc.
