AsynchronousMachineDynamics

0..1

AsynchronousMachineDynamics

Asynchronous machine model with which this turbine-governor model is associated. TurbineGovernorDynamics shall have either an association to SynchronousMachineDynamics or to AsynchronousMachineDynamics.

PropertiesCIMDataObject

ChangeSetMember

The single CIM data object in the appropriate dataset context.

SynchronousMachineDynamics

Synchronous machine model with which this turbine-governor model is associated. TurbineGovernorDynamics shall have either an association to SynchronousMachineDynamics or to AsynchronousMachineDynamics.

TurbineLoadControllerDynamics

0..1

TurbineLoadControllerDynamics

Turbine load controller providing input to this turbine-governor.

aliasName

0..1

string

The aliasName is free text human readable name of the object alternative to IdentifiedObject.name. It may be non unique and may not correlate to a naming hierarchy. The attribute aliasName is retained because of backwards compatibility between CIM relases. It is however recommended to replace aliasName with the Name class as aliasName is planned for retirement at a future time.

description

0..1

string

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.

enabled

0..1

boolean

Function block used indicator. true = use of function block is enabled false = use of function block is disabled.

mRID

0..1

string

Master resource identifier issued by a model authority. The mRID is 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, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements.

string

The name is any free human readable and possibly non unique text naming the object.
