Inheritance

Attributes

Name URI Cardinality and Range Description Inheritance
PhaseTapChangerTable cim:PhaseTapChangerTablePoint.PhaseTapChangerTable No cardinality available PhaseTapChangerTable The table of this point. direct
angle cim:PhaseTapChangerTablePoint.angle No cardinality available AngleDegrees The angle difference in degrees. A positive value indicates a positive angle variation from the Terminal at the PowerTransformerEnd, where the TapChanger is located, into the transformer. direct
b cim:TapChangerTablePoint.b No cardinality available PerCent The magnetizing branch susceptance deviation as a percentage of nominal value. The actual susceptance is calculated as follows:
calculated magnetizing susceptance = b(nominal) * (1 + b(from this class)/100). The b(nominal) is defined as the static magnetizing susceptance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form. TapChangerTablePoint
g cim:TapChangerTablePoint.g No cardinality available PerCent The magnetizing branch conductance deviation as a percentage of nominal value. The actual conductance is calculated as follows:
calculated magnetizing conductance = g(nominal) * (1 + g(from this class)/100). The g(nominal) is defined as the static magnetizing conductance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form. TapChangerTablePoint
r cim:TapChangerTablePoint.r No cardinality available PerCent The resistance deviation as a percentage of nominal value. The actual reactance is calculated as follows:
calculated resistance = r(nominal) * (1 + r(from this class)/100). The r(nominal) is defined as the static resistance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form. TapChangerTablePoint
ratio cim:TapChangerTablePoint.ratio No cardinality available float The voltage at the tap step divided by rated voltage of the transformer end having the tap changer. Hence this is a value close to one.
For example, if the ratio at step 1 is 1.01, and the rated voltage of the transformer end is 110kV, then the voltage obtained by setting the tap changer to step 1 to is 111.1kV. TapChangerTablePoint
step cim:TapChangerTablePoint.step No cardinality available integer The tap step. TapChangerTablePoint
x cim:TapChangerTablePoint.x No cardinality available PerCent The series reactance deviation as a percentage of nominal value. The actual reactance is calculated as follows:
calculated reactance = x(nominal) * (1 + x(from this class)/100). The x(nominal) is defined as the static series reactance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form. TapChangerTablePoint
