Generator at fixed power angle
Diagram of PowerAngle

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This example is a first step on the way 'from voltage source to generator model'.

Lower part of example (for comparison with and interpretation of upper part):
simplest generator description as a "voltage behind reactance".

Upper part: 3-winding generator model, isotrope with x_d = x_q.
The power-angle is artificially fixed. The correspondence is:

  Vgen1.alpha0 ~ powerAngle.delta
  Vgen1.v0     ~ exciter.v_f

In both cases the terminal voltage is fixed by the bus voltage. The results should coincide.
