GovCT1

General model for any prime mover with a PID governor, used primarily for combustion turbine and combined cycle units.

_This model can be used to represent a variety of prime movers controlled by PID governors. It is suitable, for example, for the representation of: _

    _

  • gas turbine and single shaft combined cycle turbines
    • _

    _

  • diesel engines with modern electronic or digital governors
    • _

    _

  • steam turbines where steam is supplied from a large boiler drum or a large header whose pressure is substantially constant over the period under study
    • _

    _

  • simple hydro turbines in dam configurations where the water column length is short and water inertia effects are minimal.
    • _

Additional information on this model is available in the 2012 IEEE report, Dynamic Models for Turbine-Governors in Power System Studies, 3.1.2.3 pages 3-4 (GGOV1).
