InstanceSet

1

InstanceSet

Dataset containing the data objects.

VoltageCompensatorDynamics

1

VoltageCompensatorDynamics

Voltage compensator model associated with this excitation system model.

cswitch

0..1

boolean

Power source switch (Cswitch). true = fixed voltage of 1.0 PU false = generator terminal voltage.

emax

0..1

PU

Maximum field voltage output (Emax) (> ExcSCRX.emin). Typical value = 5.

emin

0..1

PU

Minimum field voltage output (Emin) (< ExcSCRX.emax). Typical value = 0.

k

0..1

PU

Gain (K) (> 0). Typical value = 200.

rcrfd

0..1

float

Ratio of field discharge resistance to field winding resistance ([rc / rfd]). Typical value = 0.

tatb

0..1

float

Gain reduction ratio of lag-lead element ([Ta / Tb]). The parameter Ta is not defined explicitly. Typical value = 0.1.

tb

0..1

Seconds

Denominator time constant of lag-lead block (Tb) (>= 0). Typical value = 10.

te

0..1

Seconds

Time constant of gain block (Te) (> 0). Typical value = 0,02.

DiscontinuousExcitationControlDynamics

0..1

DiscontinuousExcitationControlDynamics

Discontinuous excitation control model associated with this excitation system model.

OverexcitationLimiterDynamics

0..1

OverexcitationLimiterDynamics

Overexcitation limiter model associated with this excitation system model.

PFVArControllerType1Dynamics

0..1

PFVArControllerType1Dynamics

Power factor or VAr controller type 1 model associated with this excitation system model.

PFVArControllerType2Dynamics

0..1

PFVArControllerType2Dynamics

Power factor or VAr controller type 2 model associated with this excitation system model.

PowerSystemStabilizerDynamics

0..1

PowerSystemStabilizerDynamics

Power system stabilizer model associated with this excitation system model.

PropertiesCIMDataObject

0..1

ChangeSetMember

The single CIM data object in the appropriate dataset context.

UnderexcitationLimiterDynamics

0..1

UnderexcitationLimiterDynamics

Undrexcitation limiter model associated with this excitation system model.

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.

name

0..1

string

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

DiagramObjects

0..*

DiagramObject

The diagram objects that are associated with the domain object.

Names

0..*

Name

All names of this identified object.
