Detailed model of a synchronous machine with round rotor.
Machines
There are two different models for the Round Rotor Synchronous Machine, which are mathematically equivalent. The standard model can only be used with the continuous state-space method. The discretizable model can be used with both the continuous and the discrete state-space method.
The machine is modeled in the rotor reference frame. It operates as a motor or generator; the sign of the mechanical torque determines the mode of operation (positive for motoring, negative for generating). All electrical variables and parameters are viewed from the stator side. In the component icon, phase a of the stator winding and the positive pole of the field winding are marked with a dot.
