LoadComposite

Combined static load and induction motor load effects. The dynamics of the motor are simplified by linearizing the induction machine equations.

epfd

0..1

float

Active load-frequency dependence index (dynamic) (Epfd). Typical value = 1,5.

float

Active load-frequency dependence index (static) (Epfs). Typical value = 1,5.

Active load-voltage dependence index (dynamic) (Epvd). Typical value = 0,7.

Reactive load-voltage dependence index (static) (Eqvs). Typical value = 2.

h

0..1

Seconds

Inertia constant (H) (>= 0). Typical value = 2,5.

lfac

0..1

float

Loading factor (Lfac). The ratio of initial P to motor MVA base. Typical value = 0,8.

pfrac

0..1

float

Fraction of constant-power load to be represented by this motor model (PFRAC) (>= 0,0 and <= 1,0). Typical value = 0,5.

PropertiesCIMDataObject

0..1

ChangeSetMember

The single CIM data object in the appropriate dataset context.

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.

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.
