Load Information (Edit Mode)

Concept Link IconSee Also

 

This dialog is used to view and modify the parameters associated with each load in the system. It can also be used to insert new loads and sometimes to delete existing loads. It is nearly identical in structure to its Run Mode counterpart.

The Load Information Dialog can be used to inspect and modify the model of a bus load. To view the Load Information Dialog, select the load and choose Show Dialog from the case information toolbar or right-click on the load of interest and select Load Information Dialog from the resulting local menu. The dialog has the following fields:

 

Bus Number

Unique number between 1 and 2,147,483,647 (equals 2^31 minus 1) used to identify the bus to which the load is attached. The dropdown box provides a list of all load buses with valid area/zone/owner filters. You can use the spin button to cycle through the list of load buses.

When you insert objects graphically, the Bus Number and Bus Name fields are usually set automatically to the bus upon which you placed the object.

Bus Name

Unique alphabetic identifier for the bus to which the load is attached, consisting of up to eight characters. The dropdown box lists the names of all load buses in the case with valid area/zone/owner filters.

ID

Two-character ID used to distinguish multiple loads at a bus. By default, the load ID is equal to "1 ." An identifier of ‘99’ is used to indicate an equivalent load.

Find By Number

To find a load by its number and ID, enter the number into the Bus Number field and the ID into the ID field. Then click this button.

Find By Name

To find a load by its name and ID, enter the bus name into the Bus Name field (case insensitive) and the ID into the ID field. Then click this button.

Find…

If you do not know the exact load bus number or name you are looking for, you can click this button to open the advanced search engine.

Status

Status of the load, either Closed (connected to terminal bus) or Open (not connected). You can use this status field to change the load’s status.

Labels

Clicking on this button will open the Label Manager dialog listing all the labels assigned for the selected load.

Area Number, Area Name

Number and name of the area the load is a member of.

Zone Number, Zone Name

Number and name of the zone the load is a member of.

Substation Number, Substation Name

Number and name of the substation the load and the terminal bus are members of.

Owner Number, Owner Name

Number and name of the owner the load is a member of. If the load owner is the same as the terminal bus owner, the Same Owner as Terminal Bus box will be checked. Loads DO NOT have to be owned by the same owner as the terminal bus.

OK, Save, Delete, and Cancel

OK saves your changes and closes the dialog. Save saves your changes but does not close the dialog; this allows you to use, for example, the Find By Number command to edit additional loads. Delete deletes the current load. Cancel closes the dialog without saving your changes.
