modelInfBus

Infinite slack bus, 3-phase dq0

Extends from Partials.PowerBase (Power source base, 3-phase dq0).

Information

Ideal voltage source with constant amplitude and phase when 'vPhasor_in' unconnected,
with variable amplitude and phase when 'vPhasor_in' connected to a signal-input.

Optional input:

  vPhasor_in         {norm(v), phase(v)}
   vPhasor_in[1]     in SI or pu, depending on choice of 'units'
   vPhasor_in[2]     in rad

Frequency: the source has always system-frequency.

Parameters

Type	Name	Default	Description
Boolean	use_vPhasor_in	false	= true to use input signal vPhasor_in, otherwise use {v0, alpha0}
SIpu.Voltage	v0	1	fixed voltage
SI.Angle	alpha0	0	fixed phase angle
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)

Connectors

Ports.ACdq0_n	term (from Port_n)	negative terminal
Interfaces.Electric_p	neutral (from SourceBase)	(use for grounding)
Modelica.Blocks.Interfaces.RealInput	vPhasor_in	{abs(voltage), phase}
