9.18  PHASE SHIFTER DATA

This section contains the parameters of phase shifters.  All the impedances and admittances are based on the phase shifter’s own MVA base and the nominal kV of the branch terminals.  The first line in the section must say: [PHASE SHIFTER DATA].  This is followed by the data described below.  A blank line ends the section.

1.   Bus1 Name: Bus name at one end of the phase shifter, enclosed in quotation marks.

2.   Bus1 Base kV: Nominal kV of Bus1.

3.   Bus2 Name: Bus name at the other end of the phase shifter, enclosed in quotation marks.

4.   Bus2 Base kV: Nominal kV of Bus2.

5.   Circuit Identifier: A two-character circuit identifier.  Parallel phase shifters must have different circuit identifiers.  The circuit identifier is enclosed in quotation marks.

6.   In-Service Flag: 1 if the phase shifter is in-service; 0 if it is not.  The default value is 1.

7.   Meter Flag: 0.0 if the phase shifter is metered at Bus1. 100.0 if it is metered at Bus2.   No other values are allowed. This feature is not being used in this version.

8.   Branch Name: A 12-character name for the phase shifter, enclosed in quotation marks.  The branch name is blank by default.

9.   Shift Angle: Phase shift in degrees.  A positive shift angle will cause the voltage angle of Bus1 to lead that of Bus2 in the positive sequence.

10. R: Positive-sequence series resistance (in per unit, on phase shifter’s own MVA base).

11. X: Positive-sequence series reactance (in per unit, on phase shifter’s own MVA base). R and X cannot both be zero.

12. GP1: Positive-sequence conductance on Bus1 end (in per unit, on phase shifter’s own MVA base).  It must be zero or positive.  Default value is 0.0.

13. BP1: Positive-sequence susceptance on Bus1 end (in per unit, on phase shifter’s own MVA base).  It must be zero or negative.  Default value is 0.0.

14. GP2: Positive-sequence conductance on Bus2 end (in per unit, on phase shifter’s own MVA base).  It must be zero or positive.  Default value is 0.0.

15. BP2: Positive-sequence susceptance on Bus2 end (in per unit, on phase shifter’s own MVA base).  It must be zero or negative.  Default value is 0.0.

16. R2: Negative-sequence series resistance (in per unit, on phase shifter’s own MVA base).  Default value is R.

17. X2: Negative-sequence series reactance (in per unit, on phase shifter’s own MVA base). Default value is X.  R2 and X2 cannot both be zero. 

18. GN1: Negative-sequence conductance on Bus1 end (in per unit, on phase shifter’s own MVA base). Default value is GP1.  It must be zero or positive.

19. BN1: Negative-sequence susceptance on Bus1 end (in per unit, on phase shifter’s own MVA base).  Default value is BP1. It must be zero or negative.

20. GN2: Negative-sequence conductance on Bus2 end (in per unit, on phase shifter’s own MVA base).  Default value is GP2. It must be zero or positive.

21. BN2: Negative-sequence susceptance on Bus2 end (in per unit, on phase shifter’s own MVA base).  Default value is BP2.  It must be zero or negative.

22. R0: Zero-sequence series resistance (in per unit, on phase shifter’s own MVA base). Default value is R.

23. X0: Zero-sequence series reactance (in per unit, on phase shifter’s own MVA base). Default value is X.  R0 and X0 cannot both be zero.

24. GZ1: Zero-sequence conductance on Bus1 end (in per unit, on phase shifter’s own MVA base).  Default value is GP1. It must be zero or positive.

25. BZ1: Zero-sequence susceptance on Bus1 end (in per unit, on phase shifter’s own MVA base).  Default value is BP1.  It must be zero or negative.

26. GZ2: Zero-sequence conductance on Bus2 end (in per unit, on phase shifter’s own MVA base).  Default value is GP2.  It must be zero or positive.

27. BZ2: Zero-sequence susceptance on Bus2 end (in per unit, on phase shifter’s own MVA base).  Default value is BP2.  It must be zero or negative.

28. An integer: This parameter is not being used.

29.  A floating point number:  This parameter is not being used.

30.  MW Flow Control Flag: 0 if the phase shifter angle is fixed; 1 if it is adjusted in the Power Flow Program to automatically control real power flow.

31.  Max Angle Limit: The Power Flow Program will adjust the phase shift between this value and the minimum angle limit (item 23 below).  The program requires the maximum angle to be more than 1 degree larger than the minimum angle.  The default value is 0.0.

32.  Min Angle Limit: See item 31 above. 

33.  Max Target MW: Maximum target range for flow of real power in megawatts.  This value is ignored when the MW flow control is off.  The default value is 0.0.

34.  Min Target MW: See item 33 above.

35.  Base MVA for all the impedances, conductances and susceptances. Default is the system base MVA.

36.  Impedance Correction Table Entry Number: 0 if the impedances are fixed. Otherwise, enter the impedance correction table entry number between 1 and 96, inclusive.

37.  MVA Rating1: First MVA rating for overload checking in the Power Flow Program

38.  MVA Rating2: Second MVA rating for overload checking in the Power Flow Program.

39.  MVA Rating3: Third MVA rating for overload checking in the Power Flow Program.

40. 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.

41. 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.

42. 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.

43. 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.

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