SECTION 3 COMMAND REFERENCE
3.2 MAIN WINDOW COMMANDS
The Main Window contains commands for manipulating libraries and relay types. The Main Window is initially gray when the program begins execution. After a library is opened, the name of the library is shown in the title bar of the Main Window.
Main Window
FILE MENU
NEW COMMAND
The New command lets you create a new distance relay library.
This feature is not available in this version. You can create a new library now by copying an existing library to another file and editing it.
Main Window
FILE MENU
OPEN COMMAND
The Open command lets you open an existing library for editing. TO OPEN AN EXISTING LIBRARY:
1. Select the File | Open command.
A dialog box will appear asking you for the name of the library that you want to open.
2. Use the controls in the standard file dialog box to specify the name of the library. 3. Click on "Open" to close the dialog box.
Main Window
FILE MENU
SAVE COMMAND
The Save command saves the current library to disk under the current library name. The contents of the old library are overwritten by the new information. It is wise to periodically save the file you are editing to guard against information loss in the event of a program or system failure.
TO SAVE A LIBRARY:
1. Select the File | Save command.
The cursor will turn into an hourglass while the current library is being written to disk. You may continue working after the cursor is restored to the original arrow shape.
Main Window
FILE MENU
SAVE AS COMMAND
The Save As command saves the current library to the disk under a different name. The original library is not altered or saved. After you execute this command, the library is saved to this new file whenever the Save command is used.
TO SAVE THE LIBRARY UNDER A NEW NAME:
1. Select the File | Save As command.
A dialog box will appear asking you to specify the name of the library.
2. Use the controls in the standard file dialog box to specify the name of the library.
You should name all your library files with the .DRL extension.
3. Click on "OK".
The cursor will turn into an hourglass while the current library is being written to disk. The new file name will appear in the caption bar of the Main Window. You may continue working after the cursor is restored to the original arrow shape.
Main Window
FILE MENU
EXIT COMMAND
This command lets you close the current library and shut down the Distance Relay Editor. TO EXIT THE DISTANCE RELAY EDITOR:
1. Select the File | Exit command.
If no library has been opened or if the current library has not been changed, the Main Window of the program will simply disappear.
If the current library has been modified, a dialog box will appear asking you whether the changes should be saved.
2. Click on "Yes" if you wish to save the updated library; otherwise click on "No".
Main Window
TYPE MENU
EDIT COMMAND
This command allows you to view and edit relay types. You can also create new relay types and delete existing relay types.
TO VIEW A LIST OF RELAY TYPES:
1. Select the Type | Edit command.
A dialog box will appear displaying all the relay types in the relay library.
TO DELETE A RELAY TYPE:
1. Select the relay type to be deleted from the list box. Then, click on "Delete".
The selected relay type will be removed from the list box.
Note: The program does not allow you to delete any of the five generic
relay types, “CEY-Type”, “GCX-Type”, “KD-Type”, “HCZ-Type” and “HZM-Type”, which are required for backward compatibility.
2. Click on "Close" to close the dialog box.
TO ADD A NEW RELAY TYPE:
1. Click on the "Add" button.
A dialog box will appear asking for the relay method. The methods currently available are listed in the dialog box.
2. Select the relay method and click on "OK".
A dialog box will appear asking for the relay type parameters. The method name is shown immediately above the data grid.
3. Enter the 'Type' name.
The relay type name must be unique and can have up to 18 characters.
4. Click on the 'Phase Relay' check box if this type may be a phase distance relay. 5. Click on the 'Ground Relay' check box if this type may be a ground distance
relay.
6. Click on the 'Zone 2 Supervision on OC Relay' check box if zone 2 of this relay type can supervise a nondirectional, torque-controlled overcurrent relay. 7. Enter the voltage memory duration in "Memory".
Zero means there is no memory. The program will use the prefault voltages for polarization if the time delay is less than this duration; otherwise, it will use the post-fault voltages for polarization.
8. Click on the drop down list box and select a method of polarization.
Available options include “Self Polarized”, “Cross Polarized” and “Positive-Sequence Polarized”.
9. Specify the name and default value for each of the parameters in the data grid.
The method you choose for the relay type determines the parameters that are required to model it. These parameters are listed in the data grid. Each parameter is assigned an index which is used by OneLiner/DistriView as a parameter identifier. You cannot change these indices. However, you can change the parameter names and default values, which will appear in the distance-relay info dialog box in OneLiner/DistriView. The parameter name can have up to 24 characters.
10. Click on "OK" to close the dialog box.
TO VIEW OR EDIT A RELAY TYPE:
1. Select the relay type to be edited or viewed from the list box. Then, click on "Edit".
A dialog box will appear displaying the parameters of the relay type and method.
2. View or edit the parameters of the relay type and method.
See previous page for explanation of the parameters.
Note: The program does not allow you to edit any of the five generic
relay types, “CEY-Type”, “GCX-Type”, “KD-Type”, “HCZ-Type” and “HZM-Type”, which are required for backward compatibility. The OK button is dimmed for these types.
Main Window
TYPE MENU
COPY FROM ANOTHER LIBRARY COMMAND
This command lets you copy distance relay types from another distance relay library. TO COPY RELAY TYPES FROM ANOTHER LIBRARY:
1. Select the Type | Copy from Another Library command.
A dialog box will appear asking you for the name of the library from which you would like to copy.
2. Use the controls in the standard file dialog box to specify the name of the library. Then, click on "Open" to close the dialog box.
A dialog box will appear listing the distance relay types in the relay library you specified.
3. Select the relay types you would like to copy. Click on "Select All" to copy all relay types or click on them individually in the list box.
The relay types you have selected will become highlighted.
4. Click on "Copy".
The selected relay types will be copied into the distance relay library.
