This section contains switched shunt parameters. The first line in the section must say: [SWITCHED SHUNT 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 switched shunt is attached, enclosed by quotation marks.
2. Base kV: Nominal kV of the bus.
3. In-Service Flag: 1 if the switched shunt is in-service; 0 if it is not. The default value is 1.
4. B: Positive-sequence shunt susceptance, B, in per unit. The zero-sequence of the switched shunt is calculated automatically by the program. The default value for B is 0.0.
5. Control Mode Flag: 0 if the susceptance of the switched shunt is fixed. 1 if the susceptance of the shunt banks is switched on and off incrementally in discrete steps to regulate voltage. 2 if the susceptance of the shunt banks is adjusted continuously to regulate voltage.
6. Min Target Voltage in per-unit: Ignored when the control mode is on "Fixed". The default is 0.0.
7. Max Target Voltage in per-unit: Ignored when the control mode is on "Fixed". The default is 0.0.
8. Controlled Bus Name: Name of the bus whose voltage magnitude is to be regulated by the switched shunt. The bus name is enclosed in quotation marks.
9. Controlled Bus Base kV: Nominal kV of the bus whose voltage magnitude is to be regulated by the switched shunt.
10. Number of Banks: A switched shunt can have up to 8 banks of capacitors and reactors.
11. Bank #1 Number of Steps: Number of steps for the first bank of capacitors and reactors. The number of steps in each bank can be any integer between 1 through 9, inclusive. A value of 0 means that the bank, as well as all subsequent banks, are not in use.
12. Bank #2 Number of Steps: Number of steps for the second bank of capacitors and reactors.
13. Bank #3 Number of Steps: Number of steps for the third bank of capacitors and reactors.
14. Bank #4 Number of Steps: Number of steps for the fourth bank of capacitors and reactors.
15. Bank #5 Number of Steps: Number of steps for the fifth bank of capacitors and reactors.
16. Bank #6 Number of Steps: Number of steps for the sixth bank of capacitors and reactors.
17. Bank #7 Number of Steps: Number of steps for the seventh bank of capacitors and reactors.
18. Bank #8 Number of Steps: Number of steps for the eighth bank of capacitors and reactors.
The next 16 items are the positive-sequence conductance and susceptance of the 8 banks.
19. Bank #1 G/Step: Per-unit positive-sequence conductance of each step for the first bank. This value is ignored in the current version of OneLiner.
20. Bank #1 B/Step: Per-unit positive-sequence susceptance of each step for the first bank. The susceptance is positive for a capacitor and negative for a reactor. The default value is 0.0.
21-22. Bank #2 G/Step and Bank #2 B/Step
23-24. Bank #3 G/Step and Bank #3 B/Step
25-26. Bank #4 G/Step and Bank #4 B/Step
27-28. Bank #5 G/Step and Bank #5 B/Step
29-30. Bank #6 G/Step and Bank #6 B/Step
31-32. Bank #7 G/Step and Bank #7 B/Step
33-34. Bank #8 G/Step and Bank #8 B/Step
The next 16 items are the zero-sequence conductance and susceptance of the 8 banks.
35. Bank #1 Go/Step: Per-unit zero-sequence conductance of each step for the first bank. This value is ignored in the current version of OneLiner.
36. Bank #1 Bo/Step: Per-unit zero-sequence susceptance of each step for the first bank. The default value is 0.0. The susceptance is positive for a capacitor and negative for a reactor. Enter zero if the bank is ungrounded.
37-38. Bank #2 Go/Step and Bank #2 Bo/Step
39-40. Bank #3 Go/Step and Bank #3 Bo/Step
41-42. Bank #4 Go/Step and Bank #4 Bo/Step
43-44. Bank #5 Go/Step and Bank #5 Bo/Step
45-46. Bank #6 Go/Step and Bank #6 Bo/Step
47-48. Bank #7 Go/Step and Bank #7 Bo/Step
49-50. Bank #8 Go/Step and Bank #8 Bo/Step
51. 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.
52. 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.
53. 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.
54. 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.
55. UDF: User-defined data fields. Enter the list of user defined field values as a tab delimited text string enclosed in single quotes.
