- tb
Turbine lag time constant (Tb). Typical Value = 0.1. Default: 0
- tc
Turbine lead time constant (Tc). Typical Value = 0. Default: 0
- wfspd
Switch for fuel source characteristic to recognize that fuel flow, for a given fuel valve stroke, can be proportional to engine speed (Wfspd). true = fuel flow proportional to speed (for some gas turbines and diesel engines with positive displacement fuel injectors) false = fuel control system keeps fuel flow independent of engine speed. Typical Value = false. Default: False
- teng
Transport time delay for diesel engine used in representing diesel engines where there is a small but measurable transport delay between a change in fuel flow setting and the development of torque (Teng). Teng should be zero in all but special cases where this transport delay is of particular concern. Typical Value = 0. Default: 0
- tfload
Load Limiter time constant (Tfload). Typical Value = 3. Default: 0
- kpload
Load limiter proportional gain for PI controller (Kpload). Typical Value = 1. Default: 0.0

- ldref
Load limiter reference value (Ldref). Typical Value = 1. Default: 0.0
- 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. Default: 0.0

- ka
Acceleration limiter Gain (Ka). Typical Value = 10. Default: 0.0
- ta
Acceleration limiter time constant (Ta). Typical Value = 1. Default: 0

Speed governor dead band in per unit speed (db). In the majority of applications, it is recommended that this value be set to zero. Typical Value = 0. Default: 0.0

Documentation of parent class TurbineGovernorDynamics:
Turbine-governor function block whose behavior is described by reference to a standard model

Asynchronous machine model with which this turbine-governor model is associated. Default: None
- TurbineLoadControllerDynamics
Turbine load controller providing input to this turbine-governor. Default: None
Documentation of parent class DynamicsFunctionBlock:
Abstract parent class for all Dynamics function blocks.
- enabled
Function block used indicator. true = use of function block is enabled false = use of function block is disabled. Default: False
Documentation of parent class IdentifiedObject:
This is a root class to provide common identification for all classes needing identification and naming attributes.
- DiagramObjects
The domain object to which this diagram object is associated. Default: “list”
- mRID
Master resource identifier issued by a model authority. The mRID is globally unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended. For CIMXML data files in RDF syntax conforming to IEC 61970-552 Edition 1, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements. Default: ‘’
- name
The name is any free human readable and possibly non unique text naming the object. Default: ‘’
- description
The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy. Default: ‘’
- energyIdentCodeEic
The attribute is used for an exchange of the EIC code (Energy identification Code). The length of the string is 16 characters as defined by the EIC code. References: Default: ‘’
- shortName
The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. Default: ‘’
