OpenIPSL.Electrical.Machines.PSSE.GENCLS OpenIPSL.Electrical.Machines.PSSE.GENCLS

Classic generator model that can also represent an infinite bus

Information

Synchronous machine represented by 'classical' modeling (see also [PSSE-AGV2], chapter 15).

Parametrization

This model changes its behavior depending on the value of the parameter H:

  1. H=0: The model behaves like an infinite bus where the voltage and frequency, specified by v_0 and fn, are kept constant. P and Q are then calculated accordingly (i.e., the initial values P_0 and Q_0 have no influence on the behavior of the model).
  2. H>0: "Classical Generator" model with physically-meaningful parameters, e.g., H=5 in a 100 MVA base. The parameters P_0 and Q_0 are used to specify the fixed active and reactive power injected or absorbed by the model. The parameters v_0 and fn can be used to specify the initial voltage and frequency.
  3. H>>0: By making H very large, e.g., H=1e6 in a 100 MVA base, the speed of the machine will not undergo any changes, and consequently will set the frequency f at the bus to a fixed value (i.e., fn). The parameters P_0, Q_0, v_0 and fn have the same function as in case 2.
Applications
  1. H=0: Infinite bus
  2. H>0: Can be used to model a generation facility when only limited information is available, this is the simplest model possible to represent a synchronous machine's electro-mechanical dynamics.
  3. H>>0: Can be used to model the connection to a "stiff grid".
