Inheritance

Attributes

Name URI Cardinality and Range Description Inheritance
earthing cim:SynchronousMachine.earthing No cardinality available boolean Indicates whether or not the generator is earthed. Used for short circuit data exchange according to IEC 60909. direct
earthingStarPointR cim:SynchronousMachine.earthingStarPointR No cardinality available Resistance Generator star point earthing resistance (Re). Used for short circuit data exchange according to IEC 60909. direct
earthingStarPointX cim:SynchronousMachine.earthingStarPointX No cardinality available Reactance Generator star point earthing reactance (Xe). Used for short circuit data exchange according to IEC 60909. direct
ikk cim:SynchronousMachine.ikk No cardinality available CurrentFlow Steady-state short-circuit current (in A for the profile) of generator with compound excitation during 3-phase short circuit.
- Ikk=0: Generator with no compound excitation.
- Ikk<>0: Generator with compound excitation.
Ikk is used to calculate the minimum steady-state short-circuit current for generators with compound excitation.
(4.6.1.2 in IEC 60909-0:2001).
Used only for single fed short circuit on a generator. (4.3.4.2. in IEC 60909-0:2001). direct
mu cim:SynchronousMachine.mu No cardinality available float Factor to calculate the breaking current (Section 4.5.2.1 in IEC 60909-0).
Used only for single fed short circuit on a generator (Section 4.3.4.2. in IEC 60909-0). direct
x0 cim:SynchronousMachine.x0 No cardinality available Reactance Zero sequence reactance of the synchronous machine. direct
r0 cim:SynchronousMachine.r0 No cardinality available Resistance Zero sequence resistance of the synchronous machine. direct
x2 cim:SynchronousMachine.x2 No cardinality available Reactance Negative sequence reactance. direct
r2 cim:SynchronousMachine.r2 No cardinality available Resistance Negative sequence resistance. direct
r cim:SynchronousMachine.r No cardinality available Resistance Equivalent resistance (RG) of generator. RG is considered for the calculation of all currents, except for the calculation of the peak current ip. Used for short circuit data exchange according to IEC 60909. direct
satDirectSubtransX cim:SynchronousMachine.satDirectSubtransX No cardinality available PU Direct-axis subtransient reactance saturated, also known as Xd"sat. direct
satDirectSyncX cim:SynchronousMachine.satDirectSyncX No cardinality available PU Direct-axes saturated synchronous reactance (xdsat); reciprocal of short-circuit ration. Used for short circuit data exchange, only for single fed short circuit on a generator. (4.3.4.2. in IEC 60909-0:2001). direct
satDirectTransX cim:SynchronousMachine.satDirectTransX No cardinality available PU Saturated Direct-axis transient reactance. The attribute is primarily used for short circuit calculations according to ANSI. direct
shortCircuitRotorType cim:SynchronousMachine.shortCircuitRotorType No cardinality available ShortCircuitRotorKind Type of rotor, used by short circuit applications, only for single fed short circuit according to IEC 60909. direct
voltageRegulationRange cim:SynchronousMachine.voltageRegulationRange No cardinality available PerCent Range of generator voltage regulation (PG in IEC 60909-0) used for calculation of the impedance correction factor KG defined in IEC 60909-0.
This attribute is used to describe the operating voltage of the generating unit. direct
mRID cim:IdentifiedObject.mRID No cardinality available 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. IdentifiedObject
