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: <ul> <li>gas turbine and single shaft combined cycle turbines</li> </ul> <ul> <li>diesel engines with modern electronic or digital governors </li> </ul> <ul> <li>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</li> <li>simple hydro turbines in dam configurations where the water column length is short and water inertia effects are minimal.</li> </ul> Additional information on this model is available in the 2012 IEEE report, <i><u>Dynamic Models for Turbine-Governors in Power System Studies</u></i>, 3.1.2.3 pages 3-4 (GGOV1).
