Attribute
Public ActivePowerPerFrequency
  governorSCD
Details:
Notes: Power Frequency Bias. This is the change in power injection divided by the change in frequency and negated.  A positive value of the power frequency bias provides additional power injection upon a drop in frequency.<br/>
Public Boolean
  ikSecond
Details:
Notes: Indicates whether initial symmetrical short-circuit current and power have been calculated according to IEC (Ik").<br/><br/>
Public CurrentFlow
  maxInitialSymShCCurrent
Details:
Notes:   Maximum initial symmetrical short-circuit currents (Ik" max) in A (Ik" = Sk"/(SQRT(3) Un)). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public ActivePower
  maxP
Details:
Notes: Maximum active power of the injection.<br/>
Public ReactivePower
  maxQ
Details:
Notes: Not for short circuit modelling; It is used for modelling of infeed for load flow exchange. If maxQ and minQ are not used ReactiveCapabilityCurve can be used <br/><br/>
Public Float
  maxR0ToX0Ratio
Details:
Notes: Maximum ratio of zero sequence resistance of Network Feeder to its zero sequence reactance (R(0)/X(0) max). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public Float
  maxR1ToX1Ratio
Details:
Notes: Maximum ratio of positive sequence resistance of Network Feeder to its positive sequence reactance (R(1)/X(1) max). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public Float
  maxZ0ToZ1Ratio
Details:
Notes: Maximum ratio of zero sequence impedance to its positive sequence impedance (Z(0)/Z(1) max). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public CurrentFlow
  minInitialSymShCCurrent
Details:
Notes: Minimum initial symmetrical short-circuit currents (Ik" min) in A (Ik" = Sk"/(SQRT(3) Un)). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public ActivePower
  minP
Details:
Notes: Minimum active power of the injection.<br/>
Public ReactivePower
  minQ
Details:
Notes: Not for short circuit modelling; It is used for modelling of infeed for load flow exchange. If maxQ and minQ are not used ReactiveCapabilityCurve can be used<br/><br/>
Public Float
  minR0ToX0Ratio
Details:
Notes: Indicates whether initial symmetrical short-circuit current and power have been calculated according to IEC (Ik"). Used for short circuit data exchange according to IEC 6090<br/><br/>
Public Float
  minR1ToX1Ratio
Details:
Notes: Minimum ratio of positive sequence resistance of Network Feeder to its positive sequence reactance (R(1)/X(1) min). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public Float
  minZ0ToZ1Ratio
Details:
Notes: Minimum ratio of zero sequence impedance to its positive sequence impedance (Z(0)/Z(1) min). Used for short circuit data exchange according to IEC 60909<br/><br/>
Public ActivePower
  p
Details:
Notes: Active power injection. Load sign convention is used, i.e. positive sign means flow out from a node.<br/>Starting value for steady state solutions.<br/>
Public ReactivePower
  q
Details:
Notes: Reactive power injection. Load sign convention is used, i.e. positive sign means flow out from a node.<br/>Starting value for steady state solutions.<br/>
Public Integer
  referencePriority
Details:
Notes: Priority of unit for use as powerflow voltage phase angle reference bus selection. 0 = don t care (default) 1 = highest priority. 2 is less than 1 and so on.<br/><br/>
Public PU
  voltageFactor
Details:
Notes: Voltage factor in pu, which was used to calculate short-circuit current Ik" and power Sk".<br/><br/>
