IfcElectricGenerator: public Ifc4::IfcEnergyConversionDevice¶
An electric generator is an engine that is a machine for converting mechanical energy into electrical energy.
HISTORY New entity in IFC2x4
Type Use Definition IfcElectricGenerator defines the occurrence of any electric generator; common information about electric generator types is handled by IfcElectricGeneratorType. The IfcElectricGeneratorType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcElectricGeneratorType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcElectricGeneratorType has ports or aggregated elements, such objects are reflected at the IfcElectricGenerator occurrence using the IfcRelDefinesByObject relationship.
Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcElectricGeneratorType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcElectricGeneratorType.HasPropertySets. If both are given, then the properties directly defined at IfcElectricGenerator override the properties defined at IfcElectricGeneratorType. Refer to the documentation at the supertype IfcEnergyConversionDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ElectricGeneratorTypeCommon (PSET_TYPEDRIVENOVERRIDE)
Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Material Use Definition The material of the IfcElectricGenerator is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcElectricGeneratorType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
Casing: Material from which the casing is constructed.
Composition Use Definition The IfcElectricGenerator may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcElectricGenerator and RelatedObjects contains one or more components. Aggregation use is defined for the following predefined types:
May contain IfcEngine components. Engine-Generator sets may optionally include an engine to indicate specific detail.
Port Use Definition The distribution ports relating to the IfcElectricGenerator are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the electric generator occurrence is defined by IfcElectricGeneratorType, then the port occurrences must reflect those defined at the IfcElectricGeneratorType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcElectricGenerator PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
Load (ELECTRICAL, SOURCE): Outgoing power from generator.
Whether the optional attribute PredefinedType is defined for this IfcElectricGenerator.
