| ID | Тип | Описание | Количество |
|---|---|---|---|
| ikSecond | Boolean | Indicates whether initial symmetrical short-circuit current and power have been calculated according to IEC (Ik"). Used only if short circuit calculations are done according to superposition method. | 0..1 |
| maxInitialSymShCCurrent | CurrentFlow | 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. | 1..1 |
| maxR0ToX0Ratio | Float | 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. | 1..1 |
| maxR1ToX1Ratio | Float | 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. | 1..1 |
| maxZ0ToZ1Ratio | Float | 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. | 1..1 |
| minInitialSymShCCurrent | CurrentFlow | 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. | 1..1 |
| minR0ToX0Ratio | Float | 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. | 1..1 |
| minR1ToX1Ratio | Float | 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. | 1..1 |
| minZ0ToZ1Ratio | Float | 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. | 1..1 |
| voltageFactor | PU | Voltage factor in pu, which was used to calculate short-circuit current Ik" and power Sk". Used only if short circuit calculations are done according to superposition method. | 0..1 |
| governorSCD | ActivePowerPerFrequency | 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. | 1..1 |
| maxP | ActivePower | Maximum active power of the injection. | 1..1 |
| maxQ | ReactivePower | Maximum reactive power limit. It is used for modelling of infeed for load flow exchange and not for short circuit modelling. | 1..1 |
| minP | ActivePower | Minimum active power of the injection. | 1..1 |
| minQ | ReactivePower | Minimum reactive power limit. It is used for modelling of infeed for load flow exchange and not for short circuit modelling. | 1..1 |
| referencePriority | Integer | 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. | 1..1 |
| p | ActivePower | Active power injection. Load sign convention is used, i.e. positive sign means flow out from a node. Starting value for steady state solutions. | 1..1 |
| q | ReactivePower | Reactive power injection. Load sign convention is used, i.e. positive sign means flow out from a node. Starting value for steady state solutions. | 1..1 |
