PCMD Introduction • PCMD has been designed for basic users with minimal computer familiarity. It provides the following facilities: • Wall-diagram replacement (recording of the current state of the electrical equipment and the network layout) • Automation of the switching log • Semi-automation of Switching Programme production • Simple addition of diagram fragments to Switching Programmes • Training personnel on the operation of your network • Assessment of trainees on the operation of your network • Assessment of personnel on safe-system-of-work procedures • Simple network behaviour modelling, including CB tripping responses, live/dead/isolated/earthed indication, interlocks, automation and castell key interlocking systems. • Simple network loading computation • Asset data recording • Equipment reference information storage and retrieval • Network reports, including maintenance schedules • Diagram modifications can be carried out by users.
Logging on to PCMD - 1 To log on to PCMD, the following actions are required: • Startup PCMD • Identify yourself • Enter your security details • Choose a diagram • Specify the type of diagram activity you wish to carry out
Logging on to PCMD - 2 A PC that has PCMD installed will have the following icon on the desktop: To start PCMD, double-click on this icon. Note that the PCMD security key (memory stick or SD card) should already be plugged into the PC when PCMD is started. PCMD will briefly announce its current security settings...
Logging on to PCMD - 3 … and will then display its initial log on form:
Logging on to PCMD - 4 … click on the dropdown arrow, and then select a user name Now enter the password for the chosen user account… (Note: passwords are case-sensitive) … and click on GO
Logging on to PCMD - 5 The user is now logged on to PCMD. One of the following screen layouts is displayed: Basic: Advanced: You can switch between these layouts by clicking on the Advanced View tick-box To exit PCMD, click the ‘off’ button
Logging on to PCMD - 6 For either layout, the next action is to choose a diagram set... … click on the dropdown arrow, and select a diagram set... You can hide or show the standard Schneider diagrams in the list of offered diagrams by clicking on this button
Logging on to PCMD - 7 …having selected a diagram set, the user must now choose an activity: The diagram that shows the currently recorded state of the electrical network is called the ‘Mimic diagram’. This is displayed by clicking on: Open Mimic Diagram… (Advanced View) …or Mimic Diagram (Basic View) Other options will be covered later.
Logging on to PCMD - 8 The chosen Mimic diagram is now displayed:
Understanding the diagram - 1 The Mimic diagram is always shown with a green background. • The screen layout consists of: • A command button line • The diagram window with scroll bars The Mimic diagram is shown in the diagram window, and comprises graphical symbols representing electrical lines and equipment. Multiple diagram pages are accessed using the tabs at the bottom left of the diagram window The diagram has a title box at the bottom right.
Understanding the diagram - 2 A number of different types of switchgear are identified on PCMD diagrams, and their current state is also indicated. For example: • Withdrawable CB • Off-load isolator • HV Fixed pattern CB • LV ACB (in Open state) • (Load break) switch • Fuse-switch • Switch-fuse Note: Normally-open switchgear is identified using the DNOs’ “lollypop” convention. This is a customisable item.
Understanding the diagram - 3 All diagrams must have at least one source of infeed: Mains infeed (usually from a DNO) is coloured according to its voltage (eg: red = 11kV) The other possible sources of infeed supply are Generators and Batteries. HV and LV busbars may be distinguished by their central colour (if live): • HV busbar • LV busbar
Understanding the diagram - 4 PCMD determines the current electrical state of all circuits from the state of the switchgear • Circuits that are live are shown in solid colours according to their voltage. For example: • green = 33kV • yellow = 22kV • red = 11kV • blue = 6.6kV • magenta = 3.3kV • black = LV (eg: 415V) • grey = dc • These colours may be changed if required.
Understanding the diagram - 5 Circuits that are not live are shown using patterned lines. This allows monochrome printers to be used for diagram prints. For non-live circuits, five line patterns are used: • Isolated • Faulty • Dead • Earthed • Dead/earthed (earthed beyond a transformer) Busbars are infilled with the Live colour, or a pattern if Dead, Isolated, Earthed or Dead/earthed. They may also be shown as Faulty.
Understanding the diagram - 6 There are also a few special purpose line styles: • Neutral earth • LV Busbar riser (live) • LV Busbar riser (dead) • The LV Busbar risers may also shown as isolated. • …and more switchgear: • HV Fixed pattern CB with one disconnector • Withdrawable LV CB • Contactor (open)
Understanding the diagram - 7 Electrical equipment is usually installed in secure areas (substations). A substation is shown on the diagram using a dotted line box that encloses a group of equipment items. Each substation must be assigned a unique name. PCMD uses the more generic term ‘location’, to cover equipment groupings such as switchrooms, switchboards, switchyards, and compounds.
Understanding the diagram - 8 Individual switchboards within substations can be shown by ‘nesting’ one location within another. In this example, switchroom HVAC A contains two packaged substations (M4 and M5), two UPS units, and two output LV switchboards
Understanding the diagram - 9 Central to the operation of PCMD is the manual updating of the state of switchgear (DNOs call this action ‘dressing’). When the state of a switchgear item is changed, its graphical representation is updated. The symbols used are very simple: in most cases, only the safety lock, caution sign, padlock and/or earth symbol are used, together with the open/closed switchgear state. For example: a withdrawable CB may be shown as follows: • Closed • Open • Busbar shutters isolated with safety lock and caution sign • Isolated, and circuit earthed with safety lock
Basic operations - 1 • There are three important areas of basic operation for users: • Use of the command buttons • Diagram navigation • Diagram dressing
Basic operations - 2 The command button line is laid out as follows: • Command buttons are sometimes greyed out. This may be because: • The security key licence is not enabled for this facility • This facility is not available in the current operating mode • There is nothing that this facility can currently operate upon • In the example above, ‘Undo’ is greyed out because no dressing operations have been ‘done’.
Basic operations - 3 The Management command button is used to call up the PCMD Diagram Management form: The top part of this form displays the current user’s name, and allows the user to select a different operating mode. Note: the operating mode is used to limit the range of user actions, and to modify PCMD’s response to some user actions • Buttons on this form are hidden when they are not applicable, or their action is not permitted in the current operating mode.
Basic operations - 4 The buttons on the management form allow the user to: • Select Edit mode to start editing the diagram • Make a copy of the diagram in its current state • Make a copy of the diagram in its current state and run it up, replacing the current diagram. • Save the current state and exit the diagram • Hide the Management form • and…
Basic operations - 5 … • Produce a pre-defined network report • Display administration information for the current diagram • Display PCMD application log information • Capture the current diagram page and load it to a file in emf, jpg, dwg, or dxf format. • and…
Basic operations - 6 • … • Update the reference file directory structure • Call up PC Mimic Diagram Help documentation • Export the currently displayed view of the diagram to a Word document
Basic operations - 7 While you are editing the diagram, additional buttons are displayed: • Validate the diagram, having completed any editing • Terminate editing the diagram and discard the edits • Adjust the way that diagram validation operates (following an edit) • Update all equipment definitions (from a new release of PCMD) • Clear the highlighting on the edit screen showing where validation errors are present
Basic operations - 8 The print button is used to produce a hard copy of all of the pages of the diagram in its current state. The print details form appears. From this you can choose the printer, paper size etc: To produce a PDF file, instead of a hard copy print, choose ‘PrimoPDF’ as the print device If you want to only print the currently displayed part of the current page, you should select ‘Current view’ Click on OK to proceed with the printing.
Basic operations - 9 The diagram zoom level buttons are used to adjust the magnification level that the diagram is currently displayed at. • The options are: • Magnification %: This can be changed in discrete steps using the dropdown arrow, or a value can be typed in. • Zoom in or zoom out: If you click on one of these, the next higher or lower predefined magnification level is selected • The Whole page button: Adjusts the magnification level to make the diagram just fill the entire available window area. This option also removes any temporarily displayed items, such as castell keys. In addition to the above, if you hold down the Ctrl key on the keyboard, the scroll wheel on the mouse will then adjust the diagram magnification level.
Basic operations - 10 The button is used to Magnify the contents of the current diagram window to fill the entire screen (with no borders) The Undo button is used to reverse the most recent diagram dressing action. A maximum of 25 actions may be reversed. Note that you cannot Undo actions prior to any dressing actions that have been carried out by an Automation function. The Previous Page button returns to the previously displayed page (multi-page diagrams only) • The Additional Data button is used to access: • The information window, which shows the location pointed to by the mouse pointer • The Equipment Maintenance list • The list of equipments in an abnormal state • A list of equipment types shown on the diagram
Basic operations - 11 The SysActLog button is used to call up a form that shows PCMD’s activity log for the current diagram (most recent entry is at the top): The Automation button is used to display and control automation functions (see Advanced operations).
Basic operations - 12 The Switching List button may only be used on a diagram copy. It is used to prepare switching schedule documentation (see Advanced operations). The Visibility button toggles the visibility control form: Detail, Castell, Automation, Interlocks, and Protection each have three possible states: On: maskable details of that type are always displayed. Off: maskable details of that type are always hidden. Note that a switchgear’s castell keys are displayed, when the associated switchgear is selected Auto: maskable details of that type are only revealed beyond some predefined zoom level The Future buttons allow equipment marked as future to be displayed or hidden.
Basic operations - 13 The Metering dropdown button displays and controls the Metering (network loading) functions (see Advanced operations). The available options are: • Show Metering, which enables the display of loading and computed meter data • Show Test Meter, which enables a separate meter window which shows the computed meter data for the equipment terminal at the mouse pointer location • View in Amps (or kW) allows the load and meter units to be changed to the alternative units • Use Additional Load adds in possible future loads • Show Overload highlights overloaded connections • Export Load Data exports the loading values to a spreadsheet • Import Load Data imports the loading values from a spreadsheet
Basic operations - 14 • Simple diagram navigation: • Pan: • Rotation of the mouse wheel pans the diagram up/down. • Hold the Shift key down on the keyboard and rotating the mouse wheel pans the diagram left and right. • The diagram scroll bars may also be used for panning • Zoom: • Hold the Ctrl key down on the keyboard and rotating the mouse wheel zooms the diagram in and out. • The diagram zoom level buttons on the command line may be used to adjust the zoom level Note also that mice such as the Logitech M505 allow sideways panning by pressing the mouse wheel sideways (when the Logitech application software has been installed)
Basic operations - 15 PCMD also offers ‘intelligent’ diagram navigation facilities: these are based around the use of the right mouse button: Item right-clicked: Equipment Location Line linking equipment items within same location Line linking equipment at different locations Dashed line linking castell keys <none>, at whole page view Right-click, drag mouse pointer, and release <shift> + Right-click Resulting display action: Zoom in on the equipment. Zoom to fit the location to the screen Zoom to fit the equipment items that are connected by the line Zoom to fit the locations that are connected by that line Zoom to fit all of the interlinked castell keys to the screen Zoom in on the selected position Zoom to fit selected area to the screen Whole page
Basic operations - 16 When you place the mouse pointer over an equipment symbol for two seconds, its tooltip message is displayed. For switchgear, line 1 of the tooltip message specifies the manufacturer and model designation of the switch, followed by its location and unique ID. Users may add their own annotations, which are shown as additional lines of text in the tooltip message (see Advanced operations). Tooltip messages are removed after 6 seconds, or when the mouse is moved. If you hold the Ctrl key down, and position the mouse pointer over an equipment symbol, the tooltip is immediately displayed.
Basic operations - 17 When you click on a switchgear symbol, the following form is displayed, and the attached feeder is highlighted...
Basic operations - 18 …The form lists all of the possible dressing actions that can be carried out on the switchgear while it is in its current state • For the example CB chosen, it can be dressed to the following states: • Open to Off • Enable earthing through CB, Lock closed with S/L, Isolate tripping mechanism • Tripped on fault Note that the Open to Off is shown in yellow as this operation may cause customer supply loss. If this operation is selected, the user is required to override the warning using the Proceed button on the following form:
Basic operations - 19 Operations that are potentially dangerous are shown in red. It is not possible to override warnings of this type.
Basic operations - 20 In many electrical systems, the safe operation of switchgear is managed using Castell keys. PCMD is able to accurately model the way that Castell key systems operate. On this diagram, a Castell key engraved ‘A’ is locked into the upper CB, and the key receptacle for the same key on the lower CB is empty. If the upper CB is opened, the key is released, and may be moved to the lower CB, which can then be closed. In the above example, each CB can only be closed if the key is present.
Basic operations - 21 The stages of the operation are as follows: 1 - Open the upper CB to release the key 2 – select the key to identify the places to which it can be moved. 3 – Click & drag the key to the new receptacle 4 – Close the lower CB
Basic operations - 22 Attempts to close the lower CB when the Castell key is not present are rejected:
Advanced operations - 1 • The Advanced operations section covers the following: • Additional equipment selection options • Checkpointing (archiving) and working with the System Activity log • Making copies of the Mimic diagram • PCMD’s modelling of network behaviour • Selection of User Mode • Diagram reports • How to use PCMD for training and assessment of staff
Advanced operations - 2 When a item of equipment is selected, additional options are available via the tabs at the top of the form. The Operation Commands tab is selected by default (unless there are no commands currently available). The Information button displays PCMD’s equipment definition information form. These details are used in Tooltips, and System Activity Log entries.
Advanced operations - 3 • The Details and Supply Sources buttons, which are located on the information form, display PCMD diagnostic information. • The Clones button is also located in the information section. The Clones form indicates the other display pages where the currently selected equipment item is also displayed (button greyed out if not).
Advanced operations - 4 ...and: The Asset Information button displays the asset data that has been defined for the selected equipment Asset data may be entered in the white fields (this is mode dependent). When complete, hit Carriage Return, then click Save to preserve the data. The global table button displays a table allowing all of the equipment items of the same type to have their asset details updated. The location table button displays a table allowing all of the equipment items of the same type in that location to have their asset details updated. An equipment’s asset data may be shown on the diagram using a ‘callout’ symbol. This is described later.
Advanced operations - 5 ...and: The Reference Files button displays the contents (if any) of the PC’s directory that is associated with the selected equipment The directory structure is created using the Reference Files button on the diagram management form. Windows explorer (drag and drop) is used to populate the directories, or you can drop new files directly into the Reference Files form.
Advanced operations - 6 ...and the Notes button allows: Operator warnings, Notes, and additional tooltip information to be entered for the selected device. • Operator warnings have to be acknowledged before the equipment is operated. • Notes are used to record administrative information. • Additional Tooltip data is added to the standard equipment Tooltip. • The data may be easily amended by editing the appropriate fields, and then selecting Save. If you make a mistake when amending the data, selecting the Cancel button restores the previous data.
Advanced operations - 7 The Misc. Commands tab displays equipment type-specific options: For a feeder, the Set Fault button is displayed. If a live feeder is set faulty, the nearest upstream fault clearing equipment will automatically trip • For a CB, two options are displayed: • Disable Protection: if a CB’s protection is disabled, then it will not automatically trip in response to a fault. In this case, if a feeder is set faulty, the fault is passed on beyond the CB to the next equipment upstream that is able to clear faults. • Apply warning notice: this adds a warning notice to the switchgear symbol
Advanced operations - 8 The Annotation Commands tab allows the following annotation types to be added to Copy diagrams: • Point of Isolation (switchgear) • Point of Earthing (switchgear) • Point of Work (any item) • Point of Test (any item) • Point of Spiking (cables) • Note that for Mimic diagrams, Point of Work and Point of Test may be added. You must click where you want the tip of the annotation’s arrow to be located. The position of the label can be changed by click and dragging it. Annotations are removed in the same way as they are added - by selecting the appropriate ‘Remove…’ annotation command.
