9.6  BUS DATA

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

1.   Bus Name: Name of the bus, left justified, with a maximum of 16 characters.  Any alpha-numeric characters can be used, except for ‘#’ , ‘$’ and the string delimiter (single or double quotation mark).  The bus name is enclosed in quotation marks.

2.   Base kV:  Nominal, line-to-line, voltage of the bus in kV.

3.   Bus Number: Numerical identifier for the bus.  Each bus may be assigned a number between 0 and 999999, inclusive.  The bus number is optional.  However, if the bus number is not 0, it must be unique.

4.   Area Number: Area number of the area in which bus resides.  The area number must be in the range 0-9999, inclusive.  The default value is 1.

5.   Zone Number: Zone number of the zone in which bus resides.  The zone number must be in the range 0-9999, inclusive.  The default value is 1.

6.   Location Name: Location name for bus, maximum of 24 characters.  Any alpha-numeric characters can be used, except for the string delimiter (single or double quotation mark).  The default value is first 8 characters of bus name.  The location name is enclosed in quotation marks.  The location name is usually the name of the substation.

 7.  Tap Bus Flag: 0 if it is a regular bus; 1 if it is a tap bus at the junction of two line sections; 2 if it is the middle node of a 3-terminal line.

 8.  Bus Voltage (real part): Real part of the bus voltage from a power flow solution, in per-unit.

 9.  Bus Voltage (imaginary part): Imaginary part of the bus voltage from a power flow solution, in per-unit.

10. State Plane X Coordinate: This is a floating-point number.

11. State Plane Y Coordinate: This is a floating-point number. The Y coordinate is assumed to increase in the “up” direction.

12. Substation group: Substation group number for this bus. The default value is 0.

13. Mid-point bus flag: 0 if it is a regular bus. 1 if it is a midpoint of a 3-winding transformer represented as T-equivalent.

14. 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.

15. 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.

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

An example bus data section is shown below.
