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.
