GovCT1.dm

Speed sensitivity coefficient (Dm). Dm can represent either the variation of the engine power with the shaft speed or the variation of maximum power capability with shaft speed. If it is positive it describes the falling slope of the engine speed verses power characteristic as speed increases. A slightly falling characteristic is typical for reciprocating engines and some aero-derivative turbines. If it is negative the engine power is assumed to be unaffected by the shaft speed, but the maximum permissible fuel flow is taken to fall with falling shaft speed. This is characteristic of single-shaft industrial turbines due to exhaust temperature limits. Typical value = 0.

Класс: cim: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: <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, Dynamic Models for Turbine-Governors in Power System Studies, 3.1.2.3 pages 3-4 (GGOV1).
Тип: PU Per Unit - a positive or negative value referred to a defined base. Values typically range from -10 to +10.
