modelPQsource
Power source, 3-phase dq0
Extends from Partials.PowerBase (Power source base, 3-phase dq0).
Information
Ideal source with constant (active, reactive) power when 'pq' unconnected,
with variable (active, reactive) power when 'pq' connected to a signal-input.
Optional input:
pq {p_active, p_reactive}
pq[1], pq[2] in SI or pu, depending on choice of 'units'
Frequency: the source has always system-frequency.
Use only if prescibed values for pq are compatible with the properties of the connected system.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | use_pq_in | false | = true to use input signal pq_in, otherwise use pq0 |
| SIpu.ApparentPower[2] | pq0 | {1, 0} | fixed {active, reactive} power |
| Parameter Scaling | |||
| Boolean | puUnits (from Nominal) | true | = true, if scaled with nom. values (pu), else scaled with 1 (SI) |
| Nominal | |||
| SI.Voltage | V_nom (from Nominal) | 1 | nominal Voltage (= base for pu) |
| SI.ApparentPower | S_nom (from Nominal) | 1 | nominal Power (= base for pu) |
| Initialization | |||
| PS.Voltage | V_start | V_nom | start value terminal voltage |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Ports.ACdq0_n | term (from Port_n) | negative terminal | |
| Interfaces.Electric_p | neutral (from SourceBase) | (use for grounding) | |
| Modelica.Blocks.Interfaces.RealInput | pq_in | {active, reactive} power |
