This section contains parameters of 2-terminal dc lines. The first line in the section must say: [2-TERMINAL DC DATA]. This is followed by the data described below. A blank line ends the section. In the following “Converter 1” refers to the converter at the Bus1 side, and “Convert 2” refers to the converter at the Bus2 side.
1. Bus1 Name: Name of the converter terminal at one end of the dc line, enclosed in quotation marks.
2. Bus1 Base kV: Nominal kV of Bus1.
3. Bus2 Name: Name of the converter terminal at the other end of dc line, enclosed in quotation marks.
4. Bus2 Base kV: Nominal kV of Bus2.
5. Circuit ID: A 2-character ID enclosed in quotation marks. Parallel dc lines must have different circuit IDs.
6. In-Service Flag: 1 if the dc line is in-service; 0 if it is not. The default value is 1.
7. Name: A 12-character name for the dc line, enclosed in quotation marks.
8. Rectifier Side: 0 if the Convert 1 is the rectifier; 1 if the Converter 2 is the rectifier.
9. Control Mode: 0 to control MW at rectifier; 1 to control MW at inverter; 2 to control current (amperes).
10. Control Target: MW or amperes to be held fixed by the controller. This value must be positive.
11. Control Margin: The MW target is to be reduced by this amount when the rectifier voltage is too low.
12. Scheduled dc Voltage: Scheduled dc voltage at the inverter. This value must be positive.
13. Resistance of the dc line: Resistance of the dc line in ohms. This value must be positive.
14. Number of Bridges at Converter 1: This integer value must be positive.
15. Max Angle Limit at Converter 1: This limit, in degrees, is alpha max if Converter 1 is the rectifier, and gamma max if Converter 1 is the inverter.
16. Min Angle Limit at Converter 1: This value must be positive.
17. Nominal kV of Commutation Transformer at Converter 1: The nominal kV at the dc side of the transformer in kV, line-to-line. This value must be positive.
18. Tap Position of Commutation Transformer at Converter 1: The position of the LTC tap on the ac side of the transformer, in per-unit.
19. Max Tap Position of Commutation Transformer at Converter 1: The max position of the LTC tap on the ac side of the transformer, in per-unit.
20. Min Tap Position of Commutation Transformer at Converter 1: The min position of the LTC tap on the ac side of the transformer, in per-unit. This value must be positive.
21. Tap Step Size of Commutation Transformer at Converter 1: Step size of the LTC tap, in per-unit. Set to zero if continuous.
22. Resistance of each Commutation Transformer at Converter 1: Resistance of the transformer, in per-unit, based on the MVA rating of the transformer (item 24).
23. Reactance of each Commutation Transformer at Converter 1: Reactance of the transformer, in per-unit, based on the MVA rating of the transformer (item 24).
24. MVA Rating of Each Commutation Transformer at Converter 1: The resistance and reactance are assumed to be based on this MVA rating. The program assumes that there is one commutation transformer for each bridge.
25-35: Same as items 14-24, except these are for the Converter 2.
36. 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.
37. 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.
38. 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.
39. 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.
40. 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 dc line data section is shown below.
