1. Editing the Diagram

1.1 Introduction

The Diagram Editor enables you to place symbols and primitives on the HV

Diagram either directly, or within a patch.

1.1.1 Symbols

The HV Diagram is made up of symbols that graphically represent equipment.Symbols can represent any type of equipment from Oil Switches to TelecontrolledCircuit Breakers.

1.1.2 Connections

Symbols are connected together to allow electricity to flow, and the differenttypes of connections are represented graphically. Typically, overhead lines have adifferent representation than underground cables, and cables handling differentvoltages, for example 11kV and 33kV, are usually coloured differently. Adistinction is also usually made between main line cables and spurs.

1.1.3 Dressing

Symbols are dressed to reflect their state, for example, a switch that is normallyopen will have a particular dressing to indicate this.

When an operation that will alter the state of a piece of equipment is to beperformed, an action dressing is attached to the symbol via a stalk. Typically, theaction dressing reflects the eventual appearance of the item after the operation

has been confirmed. If the action is in an instructed state, the dressing is visibleto all operators. Otherwise, it is visible only to the operator performing thechange of state.

Connections are also dressed to reflect their state; for example, Live, Dead,Isolated, Earthed, and so on.

1.2 Diagram Editor

The Diagram Editor is used to edit and construct the HV Diagram.

1.5 Layers and Levels

Layers and levels are used for setting the visibility of equipment on the HVDiagram.

1.5.1 Layers

Every graphic object is assigned a layer. Layers can be thought of as a set oftransparencies lying one on top of another. Layers can be viewed or hidden, sothat all graphics on the same layer can be viewed or hidden at once. For

example, all spur cables could be assigned the same layer so that it would beeasy to hide all spur cables by hiding the layer.

1.5.1.1 View layer for object

To view the current layer for an object:

1. Select the object whose layer you wish to view.

2. View the Properties pane.In the Visibility section, the current Layer for the selected object is

displayed.

1.7 Saving and Discarding Changes

Changes made to the diagram from the Diagram Editor can be saved ordiscarded. For graphical and database changes to be reflected in the HV Diagram,the Diagram Editor must be saved. When changes to the diagram are saved, the

diagram is automatically precompiled to update any graphic primitives that arelinked to database property values. A precompile may fail if a primitive dynamic islinked to a database property that does not exist in the database, or if a hot spotis linked to equipment in the database that does not exist. Discarding changesperforms an undo operation on all of the changes you have made since you lastsaved.

Note: An * appears in the title bar next to the title when changes made to thediagram from the Diagram Editor are not saved.

2.4.2 Placing a Symbol

There are two main steps required when placing a symbol on the HV Diagram:

Consider the database hierarchy

Place the symbol

2.4.2.1 Database hierarchy

It is important that before a symbol is placed onto the HV Diagram, considerationis given to its location in the database hierarchy.

Many symbols are configured so that they are automatically placed in a particularlocation in the hierarchy. For example, 11kV symbols may be configured so that

they are automatically placed as a child of the page. These symbols are

considered to have a default parent.

For those symbols that do not have a default parent, the equipment is placed at

the current position in the Equipment Selector. It is essential therefore that thecorrect position in the Equipment Selector is located before placing the symbol.

2.4.2.2 Placing symbols on the HV Diagram

Once the database position has been considered, the symbol can be placed on theHV Diagram.

To place a symbol on the HV Diagram:

1. Activate the Diagram Editor.


In the Symbol Palette pane, load the appropriate palette containingthe symbol you require and select the symbol to be placed on thediagram.The symbol appears in the Symbol Preview pane.

In the Editor Canvas pane, locate and select an instance of thesymbol you require.

The symbol appears in the Symbol Preview pane.

Note: The symbol appears in the Symbol Preview pane at the size it wouldappear at the current zoom level. If you zoom in, the symbol appears

larger.

4. Change the District Zone if required.

5. In the Enter the new equipment name here field, enter a name forthe plant item.Note: This is the name entered in the Name field in the EquipmentHeader.

6. Click on the Create button.The symbol is placed on the diagram.

7. If required, rotate the symbol to the desired angle using the Propertiespane.


60/88


8. Use the Equipment Header to update any details relating to thesymbol, for example, Alias.

9. In the Equipment Properties pane, update any properties that require

information.

10. Save the drawing.

2.5 Deleting

When deleting symbols or connections, it is important to consider the associateddatabase equipment.

2.5.1 Deleting Symbols

Some symbols are configured so that when they are deleted, their databaseequipment remains. Other symbols are configured so that the operator can deletethe equipment or transfer the data to another symbol.

To delete a symbol and its database entry:


2. Select the symbol to be deleted.

3. From the Edit menu, select Delete.A Question dialog is displayed, asking if you wish to transfer asset

information to another symbol.

Figure 57: Transfer asset information Question dialog

4. Click on the No button.

The graphics and database entry are deleted.

Note: Until the Diagram Editor has been saved, the deletion of the symbol can be

reversed using either the Undo or Revert to Saved options.

Note: The Delete key on the keyboard can also be used to delete a selected itemor group of selected items.

2.5.2 Transferring Data

Some symbols are configured so that when they are deleted, their databaseentries remain. Other symbols are configured so that the operator can delete thedatabase entries or transfer the asset information to another symbol.

On deletion of a symbol from the HV Diagram you can transfer the assetinformation to a new symbol. Some configuration is required to enable thisfunctionality.Refer to the Symbol Configuration course for information on the requiredconfiguration.

To transfer asset information to another symbol:

1. In the Diagram Editor, select the symbol you wish to transfer datafrom.

2. From the Edit menu, select Delete.A Question dialog is displayed asking if you wish to transfer assetinformation to another symbol.

Figure 58: Transfer asset information Question dialog

3. Click on the Yes button.The Asset Transfer window is displayed.

Note: The left-hand side of the Asset Transfer window is populated withthe asset data from the symbol being deleted.

6. Click on the Yes button.A Confirmation dialog is displayed indicating that the data was

transferred successfully.

7. Click on the OK button.

The system does the following, depending on the transfer settings in theComponent Classes table:

The target equipment is renamed with the source equipments nameand alias.

New properties containing the source equipments alias and namebefore data was transferred are created on the source equipment.These properties are named _alias and _name respectively.

The source equipments name and alias are renamed to its Equipment

ID.

Note: It is only possible to copy from one destination source to one destinationtarget at a time. If there is more than one target or source, the transfer processmust be carried out individually.

2.5.3 Deleting Connections

Connections also have an associated database entry. This requires considerationwhen deleting the graphics.

To delete a connection and its database entry:


2. Select the connection to be deleted.

3. From the Edit menu, select Delete.The connection is deleted.


64/88


2.5.4 Disconnect and Reconnect

When editing the HV Diagram it is possible to take one end of a connection,disconnect it, and reconnect it to a new plant item, so that it is possible to replacea symbol on the diagram without having to replace the connections. This results

in the connection data being retained.

To disconnect and reconnect a connection:

1. In the Diagram Editor, place down the new symbol the connection is tobe moved to.

2. Select the connection that is to be reconnected.

3. Drag the end of the connection that is to be reconnected to the hot spotto which you wish to connect it.Note: If a multi-segment connection is selected and the selected

segment has one end attached to a vertex, the end connected to thehotspot is automatically reconnected. If the selected segment isattached to a vertex at both ends then it will not be possible toreposition that segment.

4. Delete the symbol to which the connection was originally connected.


If you disconnect a connection and fail to reconnect it to a hot spot, you are giventhe option to place a new junction to connect to.

Figure 61: Create junction Question dialog

If you choose not to create a junction, the connection is reconnected back to the

plant item it was disconnected from, and no database update is made.

2.5.5 Deleting Junctions

Junctions are temporary hot spots that should be removed once the actualconnections have been put in place on the diagram. Therefore, when deleting a

junction, it is usually appropriate to delete the associated database entry.

To delete a junction:

1. In the Diagram Editor, select the junction to be deleted.

2.6 Troubleshooting

The following are common errors and their solutions when working in theDiagram Editor.

2.6.1 Component Name Already Exists

Message:Failed to copy component tree in RDBMS as component namealready exists here.

This message occurs when placing symbols on the HV Diagram. It indicates thatthe equipment name that you have chosen is the same as another item with thesame parent. The system does not allow siblings to have the same name.

Figure 62: Component name already exists message

Solution: Click on the OK button and place down the symbol again with adifferent name.

2.6.2 Component Already Exists

Message: This Component already exists. Do you want to use the sameinstance?

This message occurs when placing symbols on the HV Diagram. It indicates thatthe component name that you have chosen is the same as another componentwith the same parent. The system does not allow siblings to have the samename.


66/88


Figure 63: Component already exists Question d ialog

Solution: On most occasions, select No and place down the symbol again with adifferent name. If the symbol being placed actually represents a symbol that alsoexists in another world and this name is intended to be the same, select Yes andboth symbols will be linked to the same components.

2.6.3 Connection Already Exists

Message: A connection already exists between these components. Doyou want to use this connection?

This message occurs when connecting symbols on the HV Diagram. It indicates

that the two hot spots being linked are already connected in the database. This isnot a problem if the connection exists in another world.

Figure 64: Connection already exists Question dialog

Solution: Select Yes if the connection exists in another world and you wish tolink to the same database entry. Otherwise, investigate why the link exists whilstthe graphic has been deleted.

2.6.4 Symbol with no components

Message: There are n hot spots and 0 components. Cannot place thissymbol.

This message occurs when placing symbols on the HV Diagram. It indicates that

the components to which the symbols hot spots should be linked cannot belocated - the components may have been deleted accidentally.

3. Patches

3.1 Introduction to Patching

A patch is a section of the HV Diagram that is modified to show change. Patching

provides a controlled manner in which to update the HV Diagram and associatedplant database details. There are two basic types of patch:

Planned patchesThese are introduced to the HV Diagram as part of aplanned job.

Unplanned (Temporary) patchesThese are created when temporaryconnectivity changes are made to the network topology as part of a job,

for example, when there is a fault condition.

3.2 Patch Versions

A single patch can have many versions. Each version is a copy of the previous

version with additional changes. A series of patch versions signify the statechanges within a drawing area with the final patch version representing the final

state of the drawing area.

3.3 Patch Introduction

A patch is introduced into the current HV Diagram by creating a patch operationin a schedule (planned job). When a patch is successfully introduced the HVDiagram and plant databases are updated appropriately on a global level.

3.4 Multiple Worlds

A patch can cover plant that appears in multiple worlds. For example, a patchmay include a new circuit breaker that appears in both the 11kV and 33kV world.

Note: Telecontrolled items should not be introduced via a patch.

3.5 Privileges

Only operators with suitable user privileges can:

Create patches

Edit patches using the Diagram Editor tool

Create new versions of patches

Mark patches as ready for introduction to the HV Diagram

Mark patches as not ready for introduction to the HV Diagram


70/88


56 GE Energy

Introduce patches

Delete patches

3.6 Patch Life Cycle

The following diagram illustrates the life cycle of a patch:

Figure 66: Patch Life Cycle

A patch has the following states:

Created - A patch is in a Created state when the details of the patch areentered correctly in the Create Patch window. A patch can only be editedwhen it is in a Created state; this includes editing the patch directlyusing the Diagram Editor tool, editing the details of the patch, creating anew version of the patch, and so on.

Ready - Only patches, which have been marked as being Ready, can be

introduced to the HV Diagram.

A patch that is Ready has the following characteristics:

Its details, that is, its Name, Description, Version and Reference

Number cannot be edited.

It cannot be edited using the Diagram Editor tool.

A patch that is Ready can only be moved back into a Created state if it isnot included in a planned job.

Introduced - A patch is introduced as part of a schedule. Once it isadded to a schedule the patch follows the life cycle defined for a

schedule.


71/88


GE Ene rgy 57

3.7 Patch Behaviour

Any number of patches can be created within a drawing but plannedpatches cannot overlap each other.

Planned patches cannot be introduced on the network if they overlapwith unplanned patches.

Unplanned patches can be introduced on the network even if theyoverlap with planned patches in a Created, Ready or Introduced state.

A single patch can be created against equipment that is present inmultiple worlds, for example 11kV and 33kV.

A single patch can have many versions. Each version can be consideredas a copy of the previous version with an adjustment that indicates thenew state of the drawing with the final patch version representing the

final state of the drawing area.

A patch version is introduced at the required time into the current HVDiagram by creating a patch operation in the Switching Log of aschedule.

An unplanned patch is created automatically and set to an Introducedstatus in a job as follows:

Unplanned Job Any temporary connectivity operation is Proposed,

Instructed or Confirmed.

Schedule Any temporary connectivity operation is Created.

Note: When all temporary operations associated with the original jobthat was used to create them are removed, the unplanned patch isremoved from the Patches list.

Unplanned patches created by applying temporary cuts, jumpers orearths interact with planned patches as follows:

A planned patch whose scope includes temporary operations can becreated, but the temporary operations are not visible in the patch.

When a temporary operation exists within the scope of a planned

patch, the system does not allow the patch to be introduced until thetemporary operation is removed.

The system does not allow any temporary operations in a plannedpatch.
