CIM Issues #5045
Voltage-dependent reactive capability curve support
Description
Per CDV country comments CH_61, NO54 & SE59 for 301 Ed7:
Voltage dependent capability curves are currently not supported by CIM.
Proposed Solution
Voltage dependent capability curves deferred to CIM18.
Assign to Physical Devices Subgroup
Decision
[PDG]
1. To propose a new terminalVoltage attribute to the ReactiveCapabilityCurve
2. Add the coolantTemperature/hydrogenPressure & the proposed terminalVoltage attributes to the 452 EQ profile
3. Add multiple ReactiveCapabilityCurve to one SynchronousMachine to 452
Release Notes
changes to 301
- new attribute ReactiveCapabilityCurve.referenceVoltage
- change of cardinalities between ReactiveCapabilityCurve and EquivalentInjection
- modifications of associations between ReactiveCapabilityCurve and SynchronousMachine (change role name InitiallyUsedBySynchronousMachines to InitiallyUsedBySynchronousMachine; change role name ReactiveCapabilityCurves to ReactiveCapabilityCurve and SynchronousMachines to SynchronousMachine; change of cardinalities)
- modified the association role description (SynchronousMachine.InitialReactiveCapabilityCurve) to add: The reference voltage (exchnaged by ReactiveCapabilityCurve.referenceVoltage) for this ReactiveCapabilityCurve shall be equal to the BaseVoltage.nominalVoltage of the ConnectivityNode to which the Equipment is connected to. The information is obtained via the containment of the Equipment or the ConnectivityNode.
- Change role name from VsConverterDCSides to VsConverter, change cardinalities
- Add referenceVoltage to VsCapabilityCurve
Changes to 452
- added attribute ReactiveCapabilityCurve.referenceVoltage
- added attribute ReactiveCapabilityCurve.coolantTemperature
- added attribute ReactiveCapabilityCurve.hydrogenPressure
- change of cardinalities between ReactiveCapabilityCurve and EquivalentInjection
- change of cardinalities and role names between ReactiveCapabilityCurve and EquivalentInjection and SynchronousMachine
- add constraint: Constraint 1: A ReactiveCapabilityCurve shall have an instance of either ReactiveCapabilityCurve.SynchronousMachine or ReactiveCapabilityCurve.EquivalentInjection.
-- Add referenceVoltage to VsCapabilityCurve, update association cardinalities and role names
- The constraint C:452:EQ:SynchronousMachine:reactiveLimits shall be changed to:
ReactiveCapabilityCurve-s are not required if the reactive power limits of the SynchronousMachine do not vary with real power output. SynchronousMachine.minQ and SynchronousMachine.maxQ are required if ReactiveCapabilityCurve.SynchronousMachine and SynchronousMachine.InitialReactiveCapabilityCurve are not provided. If one or many of the association ends ReactiveCapabilityCurve.SynchronousMachine and/or SynchronousMachine.InitialReactiveCapabilityCurve are provided they take precedence to the information provided by the attributes SynchronousMachine.minQ and SynchronousMachine.maxQ. However, if both SynchronousMachine.minQ, SynchronousMachine.maxQ and ReactiveCapabilityCurve are present, the SynchronousMachine.minQ shall be equal to the min of CurveData.y1value-s and SynchronousMachine.maxQ shall be equal to the max of CurveData.y2value-s.
New constraint
If a ReactiveCapabilityCurve is provided for a SynchronousMachine, it takes precedence to the information provided by the attributes GeneratingUnit.maxOperatingP and GeneratingUnit.minOperatingP. Any operational constraints are defined by range constraint exchanged in other profile which defines these operational constraints. Validation of this constraint shall have severity “Info” in case GeneratingUnit.maxOperatingP and GeneratingUnit.minOperatingP are outside the ReactiveCapabilityCurve defined for the nominal voltage of the connected node.
