9.7  BUS REGULATION DATA

This section contains generator regulation parameters.  The first line in the section must say: [BUS REGULATION DATA].  This is followed by the data described below.  A blank line ends the section.

1.   Bus Name: Name of the bus to which the generator is attached.  The bus name is enclosed in quotation marks.

2.   Base kV: Nominal kV of the generator bus.

3.   Generator Reference Angle: The angle of the voltage source in the generator model.  This angle and the open-circuit voltage (item 8) are used in the flat-generator-voltage start option of OneLiner only.  The default value is 0.0.

4.   Regulation Type Flag: 0 if the generator regulates voltage.  1 if the generator has fixed MW and MVAR output.  2 if the generator is on the system slack bus.  The default type is 0.

5.   Scheduled Voltage:  Scheduled voltage magnitude in per-unit.  This value is used only if the generator is regulating voltage.  The default value is 1.0.

6.   Regulated Bus Name: The name of the bus whose voltage magnitude is to be regulated by the generator.  The regulated bus name is enclosed in quotation marks.  The default name is the local bus name.

In most cases, the generator regulates the voltage at its own terminal.  If the generator regulates the voltage at another bus, the bus being regulated must be a load bus.

7.   Regulated Bus Base kV: Nominal kV of the regulated bus.  The default value is nominal kV of the local bus.

8.   Generator’s Open Circuit Voltage: The magnitude of the voltage source in the generator model, in per-unit.  This value and the referenced angle are used in the flat-generator-voltage start option of OneLiner only.  The default value is 1.0.

9.   Current limit A: Maximum phase current output during a fault, in amperes.

10. Current limit B: Maximum phase current output during a fault, in amperes.

11. Current limit C: Not used. Set to 0.0.

12. Memo: Comments with a maximum of 512 characters.  Any alpha-numeric characters can be used, except for the string delimiter (single or double quotation mark).  The comment text is enclosed in quotation marks.

13. Tags: Tag string with a maximum of 512 characters.  Tags in string are separated by semicolon. Any alpha-numeric characters can be used, except for the string delimiter (single or double quotation mark).  The tag string is enclosed in quotation marks.

14. UDF: User-defined data fields. Enter the list of user defined field values as a tab delimited text string enclosed in single quotes.
