This section contains parameters of generating units. All per-unit impedances for generators are based on the rating of the units and not the system MVA. The first line in the section must say: [GENERATOR UNIT 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, in quotation marks.
2. Base kV: Nominal kV of the generator bus.
3. Generating Unit Identifier: A 2-character identifier used to differentiate between multiple generating units on the same bus. The identifier is enclosed in quotation marks.
4. In-Service Flag: 1 if the generator is in-service; 0 if it is not. The default value is 1.
5. R": The subtransient resistance (per-unit on generator base) in the positive-sequence generator model.
6. X": The subtransient reactance (per-unit on generator base) in the positive-sequence generator model. R” and X” cannot both be zero.
7. R': The transient resistance (per-unit on generator base) in the positive-sequence generator model.
8. X': The transient reactance (per-unit on generator base) in the positive-sequence generator model. R’ and X’ cannot both be zero.
9. R: The synchronous resistance (per-unit on generator base) in the positive-sequence generator model
10. X: The synchronous reactance (per-unit on generator base) in the positive-sequence generator model. R and X cannot both be zero.
11. R2: The internal resistance (per-unit on generator base) in the negative-sequence generator model.
12. X2: The reactance (per-unit on generator base) in the negative-sequence generator model. R2 and X2 cannot both be zero.
13. R0: The internal resistance (per-unit on generator base) in the zero-sequence generator model.
14. X0: The internal reactance (per-unit on generator base) in the zero-sequence generator model. R0 and X0 cannot both be zero.
15. RN: Resistive component of neutral impedance in ohms (do not multiply by 3). The default value is 0.0.
16. XN: Reactive component of neutral impedance in ohms (do not multiply by 3). The default value is 0.0.
17. MVA: MVA rating of the generating unit. The default value is the system MVA.
18. Scheduled MW: Scheduled MW output. The default value is 0.0.
19. Scheduled MVAR: Scheduled MVAR output. This value is used only if the generator has fixed MW and MVAR output (specified in the Bus Regulation Section). The default value is 0.0.
20. Minimum MW: Minimum MW output. The default value is -9999.0.
21. Maximum MW: The maximum MW output. The default value is 9999.0. The MW limits are not used in this version of the program, but they will be used to limit the output of the system and area slack generators in future versions.
22. Minimum MVAR: Minimum MVAR output. The default value is -9999.
23. Maximum MVAR: Maximum MVAR output. The default value is 9999.0. The MVAR limits are used only if the generator is regulating voltage.
24. Actual MW Generation: Actual MW generation, from a solved power flow solution.
25. Actual MVAR Generation: Actual MVAR generation, from a solved power flow solution.
26. 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.
27. In-service Date: Set to 0 if not available. Otherwise enter an unsigned 32-bit integer that store the year/month/date information given by the CTime object in Microsoft Foundation Class.
28. Out-of-Service Date: Set to 0 if not available. Otherwise enter an unsigned 32-bit integer that store the year/month/date information given by the CTime object in Microsoft Foundation Class.
An example generator data section is shown below.
