QuasiStatic SM Electrical Excited
Electrical excited synchronous machine with optional damper cage
Description
Connections
Parameters
Modelica Standard Library
The QuasiStatic SM Electrical Excited component models a polyphase synchronous induction machine.
Resistances and stray inductances of the machine refer to an m-phase stator. The symmetry of the stator and the supply are assumed. Rotor asymmetries are modeled resistances and stray inductances in the d- and q-axis.
The following losses are modeled:
heat losses in the temperature dependent stator winding resistances
heat losses in the temperature dependent excitation winding resistance
heat losses in the temperature dependent damper cage resistances
brush losses in the excitation circuit
friction losses
core losses (only eddy current losses, no hysteresis losses)
stray load losses
