9.13  LOAD UNIT DATA

This section contains load unit parameters.  The first line in the load unit data section must say: [LOAD 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 load is attached, enclosed in quotation marks.

2.   Base kV: Nominal kV of the bus.

3.   Load Unit Identifier:  A two-character identifier used to differentiate between multiple load units on the same bus.  The identifier is enclosed in quotation marks. 

4.   In-Service Flag: 1 if the load is in-service; 0 if it is not.  The default value is 1.

5.   MW Constant Power:  Megawatts (constant-power component) consumed.  The default value is 0.0.

6.   MVAR Constant Power:  Megavars (constant-power component) consumed.  The default value is 0.0.

7.   MW Constant Current: Megawatts (constant-current component) consumed when the voltage is at 1.0 per unit.  The default value is 0.0.  The constant-current component is not yet working in this version. 

8.   MVAR Constant Current: Megavars (constant-current component) consumed when the voltage is at 1.0 per unit.  The default value is 0.0.  The constant-current component is not yet working in this version. 

9.   MW Constant Impedance: Megawatts (constant-impedance component) consumed when the voltage is at 1.0 per unit.  The default value is 0.0.

10. MVAR Constant Impedance: Megavars (constant-impedance component) consumed when the voltage is at 1.0 per unit.  The default value is 0.0.

11. 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.

12. 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.

13. 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 load unit data section is shown below.
