Documentation of parent class TurbineGovernorDynamics:

Turbine-governor function block whose behavior is described by reference to a standard model

SynchronousMachineDynamics

Turbine-governor model associated with this synchronous machine model. Default: “list”

AsynchronousMachineDynamics

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: ‘’
