MktGeneratingUnit

Additional equipment container beyond the primary equipment container. The equipment is contained in another equipment container, but also grouped with this equipment container.

The aggregate flag provides an alternative way of representing an aggregated (equivalent) element. It is applicable in cases when the dedicated classes for equivalent equipment do not have all of the attributes necessary to represent the required level of detail. In case the flag is set to “true” the single instance of equipment represents multiple pieces of equipment that have been modelled together as an aggregate equivalent obtained by a network reduction procedure. Examples would be power transformers or synchronous machines operating in parallel modelled as a single aggregate power transformer or aggregate synchronous machine. The attribute is not used for EquivalentBranch, EquivalentShunt and EquivalentInjection.

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.

The planned unused capacity (spinning reserve) which can be used to support emergency load.

The generic action that is performed on the power system resource

A generating unit may have one or more cost curves, depending upon fuel mixture and fuel cost.

A generating unit may have an operating schedule, indicating the planned operation of the unit.

Governor motor position limit.

Governor Speed Changer Droop. This is the change in generator power output divided by the change in frequency normalized by the nominal power of the generator and the nominal frequency and expressed in percent and negated. A positive value of speed change droop provides additional generator output upon a drop in frequency.

A generating unit may have a gross active power to net active power curve, describing the losses and auxiliary power requirements of the unit.

High limit for secondary (AGC) control.

Default initial active power which is used to store a powerflow result for the initial active power for this unit in this network configuration.

Specifies the availability of the equipment. True means the equipment is available for topology processing, which determines if the equipment is energized or not. False means that the equipment is treated by network applications as if it is not in the model.

Low economic active power limit that shall be greater than or equal to the minimum operating active power limit.

Minimum time interval between unit shutdown and startup.

This is the minimum operating active power limit the dispatcher can enter for this unit.

Detail level of the generator model data.

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.

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

All names of this identified object.

The equipment is enabled to participate in network analysis. If unspecified, the value is assumed to be true.

The nominal power of the generating unit. Used to give precise meaning to percentage based attributes such as the governor speed change droop (governorSCD attribute). The attribute shall be a positive value equal to or less than RotatingMachine.ratedS.

Specifies the availability of the equipment under normal operating conditions. True means the equipment is available for topology processing, which determines if the equipment is energized or not. False means that the equipment is treated by network applications as if it is not in the model.

Generating unit economic participation factor. The sum of the participation factors across generating units does not have to sum to one. It is used for representing distributed slack participation factor. The attribute shall be a positive value or zero.
