CurrentFlow Data Type

Maximum allowable peak short-circuit current of busbar (Ipmax in IEC 60909-0). Mechanical limit of the busbar in the substation itself. Used for short circuit data exchange according to IEC 60909.

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.

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.

The offset current that the Petersen coil controller is operating from the resonant point. This is normally a fixed amount for which the controller is configured and could be positive or negative. Typically 0 to 60 A depending on voltage and resonance conditions.

The control current used to control the Petersen coil also known as the position current. Typically in the range of 20 mA to 200 mA.

The highest operating current (Ib in IEC 60909-0) before short circuit (depends on network configuration and relevant reliability philosophy). It is used for calculation of the impedance correction factor KT defined in IEC 60909-0.

The maximum current the varistor is designed to handle at specified duration. It is used for short circuit calculations and exchanged only if SeriesCompensator.varistorPresent is true. The attribute shall be a positive value.

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).

Converter DC current, also called Id. It is converter’s state variable, result from power flow.

The maximum direct current (Id) on the DC side at which the converter should operate. It is converter’s configuration data use in power flow. The attribute shall be a positive value.

The minimum direct current (Id) on the DC side at which the converter should operate. It is converter’s configuration data used in power flow. The attribute shall be a positive value.

Rated converter DC current, also called IdN. The attribute shall be a positive value. It is converter’s configuration data used in power flow.

DC current target value. It is converter’s control variable used in power flow. The attribute shall be a positive value.

The maximum continuous current carrying capacity in amps governed by the device material and construction. The attribute shall be a positive value.

The normal value for limit on current flow. The attribute shall be a positive value or zero.

Limit on current flow. The attribute shall be a positive value or zero.
