Description

AC I Source

Represent single or three-phase AC current source with a parallel RLC impedance

Table of Contents

The current source always has a parallel impedance. This impedance is made up of series or parallel connected R, L, C elements.

Mask and Parameters

SI or pu units:

SI: Specifies the values of the RLC elements, voltage, current or frequency in international units (ohm, henry, farad, volt, ampere and hertz);
pu: Specifies the values of the RLC elements, voltage, current or frequency in pu;

Name	Description	Unit
Starting mode (Slow/Fast)	If “Fast”, the source is immediately activated or deactivated. If “Slow”, when the source is activated, the amplitude of the source increases linearly from zero to the steady-state value. When the source is deactivate, the amplitude of the source decreases linearly from the steady-state value to zero.	-
RLC type	Series (series R, L, C) or parallel (parallel R, L, C)	-
Base Power (total)	Base power for three phase	MVA
Base voltage (rmsLN)	Base voltage phase to ground	kV
Base Frequency	Base frequency	Hz
Amplitude (peak)	Peak value of the amplitude for the source current in amperes (or pu) for each phase	A (or pu)
Angle	Angle of phase A in degrees. The current source is always in balanced and positive sequence.	degrees
R	Resistance value in ohms	ohms (or pu)
L	Inductance value	henry (or pu)
C	Capacitor value	farad (or pu)

The current source injects a current from one bus (port) to another (port), without grounding.
