Description

1

Bus1

string
(bus def.)

Name of bus to which source is connected.
bus1=busname
bus1=busname.1.2.3

2

Amps

real

A

Magnitude of current source, each phase, in Amps.

3

Angle

real

0.0

°

Phase angle of first phase: e.g.,Angle=10.3.
Phase shift between phases is assumed 120 degrees when number of phases <= 3

4

Frequency

real

Hz

Source frequency. Defaults to circuit fundamental frequency.

5

Phases

integer

3

Number of phases. For 3 or less, phase shift is 120 degrees.

6

ScanType

string
(from enum. Scan Type)

Positive

Maintain specified sequence for harmonic solution. Default is positive sequence. Otherwise, angle between phases rotates with harmonic.

7

Sequence

string
(from enum. Sequence Type)

Positive

Set the phase angles for the specified symmetrical component sequence for non-harmonic solution modes. Default is positive sequence.

8

Yearly

string
(LoadShape name)

LOADSHAPE object to use for the per-unit current for YEARLY-mode simulations. Set the Mult property of the LOADSHAPE to the pu curve. Qmult is not used. If UseActual=Yes then the Mult curve should be actual Amp.

Must be previously defined as a LOADSHAPE object.

Is set to the Daily load shape when Daily is defined. The daily load shape is repeated in this case. Set to NONE to reset to no loadshape for Yearly mode. The default is no variation.

9

Daily

string
(LoadShape name)

LOADSHAPE object to use for the per-unit current for DAILY-mode simulations. Set the Mult property of the LOADSHAPE to the pu curve. Qmult is not used. If UseActual=Yes then the Mult curve should be actual A.

Must be previously defined as a LOADSHAPE object.

Sets Yearly curve if it is not already defined. Set to NONE to reset to no loadshape for Yearly mode. The default is no variation.

10

Duty

string
(LoadShape name)

LOADSHAPE object to use for the per-unit current for DUTYCYCLE-mode simulations. Set the Mult property of the LOADSHAPE to the pu curve. Qmult is not used. If UseActual=Yes then the Mult curve should be actual A.

Must be previously defined as a LOADSHAPE object.

Defaults to Daily load shape when Daily is defined. Set to NONE to reset to no loadshape for Yearly mode. The default is no variation.

11

Bus2

string
(bus def.)

Name of bus to which 2nd terminal is connected.
bus2=busname
bus2=busname.1.2.3

Default is Bus1.0.0.0 (grounded-wye connection)

12

Spectrum

string
(Spectrum name)

default

Harmonic spectrum assumed for this source.

13

BaseFreq

real

Hz

Base Frequency for ratings.

14

Enabled

boolean

True

Indicates whether this element is enabled.

15
