A simulation model is developed which accounts for an orthotropic as opposed to an axisymmetric rotor, i.e., rotors are considered whose stiffness and inertial properties in two mutually orthogonal planes are different. A rotor-fixed formulation is employed to define the rotor’s elastic deflections. Favorable characteristics of this formulation are that (a) the rotor’s inertial and stiffness properties are constant, and (b) the modal coordinates are nonoscillatory during synchronous motion. The validity of the formulation is verified by conducting transient simulations for a rotor having the approximate physical dimensions of a two-pole 500 MW alternator. The simulation model correctly simulates the rotor’s theoretically predicted dynamic behavior.

Transformer-inductor simulation model not only reflects the characteristics of magnetic path and circuit, but also brings in magnetic components that reflected the parasitic capacitance. There are further research, strict derivation and magnetic circuit equivalent for the model in this article. Under the condition of considering hysteresis, saturation effect we can conclude a new modeling and its equivalent, which can make the magnetic curve and characteristic get better fitting. It shows that the transformer-inductance simulation model is easy to spread and use.
