PowerElectronicsConnection
Class Description
A connection to the AC network for energy production or consumption that uses power electronics rather than rotating machines.
Attributes
| Name | Type | Description |
|---|---|---|
| maxIFault | PU | Maximum fault current this device will contribute, in per-unit of rated current, before the converter protection will trip or bypass. |
| maxQ | ReactivePower | Maximum reactive power limit. This is the maximum (nameplate) limit for the unit. |
| minQ | ReactivePower | Minimum reactive power limit for the unit. This is the minimum (nameplate) limit for the unit. |
| p | ActivePower | Active power injection. Load sign convention is used, i.e. positive sign means flow out from a node. Starting value for a steady state solution. |
| q | ReactivePower | Reactive power injection. Load sign convention is used, i.e. positive sign means flow out from a node. Starting value for a steady state solution. |
| r | Resistance | Equivalent resistance (RG) of generator. RG is considered for the calculation of all currents, except for the calculation of the peak current ip. Used for short circuit data exchange according to IEC 60909. |
| r0 | Resistance | Zero sequence resistance of the synchronous machine. |
| ratedS | ApparentPower | Nameplate apparent power rating for the unit. The attribute shall have a positive value. |
| ratedU | Voltage | Rated voltage (nameplate data, Ur in IEC 60909-0). It is primarily used for short circuit data exchange according to IEC 60909. The attribute shall be a positive value. |
| rn | Resistance | Negative sequence Thevenin resistance. |
| x | Reactance | Positive sequence Thevenin reactance. |
| x0 | Reactance | Zero sequence Thevenin reactance. |
| xn | Reactance | Negative sequence Thevenin reactance. |
