HeatInputCurve

Relationship between unit heat input in energy per time for main fuel (Y1-axis) and supplemental fuel (Y2-axis) versus unit output in active power (X-axis). The quantity of main fuel used to sustain generation at this output level is prorated for throttling between definition points. The quantity of supplemental fuel used at this output level is fixed and not prorated.

ThermalGeneratingUnit

ThermalGeneratingUnit

A thermal generating unit may have a heat input curve.

InstanceSet

InstanceSet

Dataset containing the data objects.

auxPowerMult

PU

Power output - auxiliary power multiplier adjustment factor.

auxPowerOffset

ActivePower

Power output - auxiliary power offset adjustment factor.

heatInputEff

PU

Heat input - efficiency multiplier adjustment factor.

Heat input - offset adjustment factor.

isNetGrossP

0..1

boolean

Flag is set to true when output is expressed in net active power.

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.

curveStyle

0..1

CurveStyle

The style or shape of the curve.

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.

UnitMultiplier

Multiplier for X-axis.
