2. REF 54_ Pro-tection Relay

The REF 54_ type protection relay is designed to be used for the protection, control, meas-uring and supervision of medium voltage networks. It can be used with any type of switch-gear including single busbar, double busbar and duplex systems. The protection relayincludes energizing inputs for conventional current and voltage transformers and currentand voltage sensors.

The REF 54_ protection relay is based on a multiprocessor environment that increases per-formance. Digital signal processing combined with a powerful CPU and distributed I/O han-dling facilitates parallel operations and improves response times and accuracy. The MMIincluding an LCD display with different views makes the local use of the REF 54_ safe andeasy. The MMI instructs the user how to proceed.

The REF 54_ protection relay is part of the PYRAMID substation automation for Distri-bution Automation and extends the functionality and flexibility of the concept further. Thisis possible due to the state-of-the-art technology used in PYRAMID.

Then a new attempt to open the password has tobe done. When the password has been opened (or failed), the message reappears in the as-sisting window. Messages are cleared by pressing the C button for 2 seconds

When the C button is pressed during the setting of a password, the setting proce-dure will be cancelled. In other situations, the C button is used to clear the assistingwindow.

When a message of high priority is indicated in the assisting window, no help messages aredisplayed until the window has been cleared.

4.3.3. Menus The main menu is the main view of the technical level, where the first row is always dedi-cated for the header text of the main level. The main menu is followed by the group menuand the subgroup menu which form the hierachical structure.

4.3.4. Parametermenu

One parameter on this level consists of 2 rows:

row 1: parameter text row 2: "=" sign and setting value including the unit when specified (numeric value, character

string, enumerator).

On the parameter level the cursor moves two rows at a time

As on the main level and group level, the first row of the display is dedicated for the headertext. The header text is advisory and shows the position of the parameter menu in the menusystem in the form of a path (Main menu/Group menu/Subgroup menu/Parameter menu)

If the parameter to be entered is password-protected, the procedure for opening the param-eter menu is the same as for the main menu.

4.3.5. Moving in the menus

The arrow buttons up and down are used for moving in the parameter menu. When the ap-propriate parameter is highlighted, the setting mode is activated by pressing the E button.

4.4. Setting a pa-rameter

When the setting mode has been activated by pushing the E button, the first digit or characterof the setting value/text of the concerned parameter is blinking (in the case of an enumerator,the entire text is blinking). Now the digit/character can be set by using the up/down buttons.

The next digit/character to be set is activated by pressing the arrow buttons right or left(when setting an enumerator type parameter, the left and right arrows have no function).

Fig. 4.4.-1. Parameter setting

The setting is confirmed by pressing the E button. Before confirming, the previous settingvalue can be restored by pressing the C button.

If an illegal setting value is confirmed in the setting mode, a message tells the user that thesetting is out of range. The previous parameter value remains unchanged.

5. Protection re-lay indications

There are two different kinds of indication messages available in the assisting window:

information about the protection relay functions and the condition of the protection relay (self-diagnosis) together with a LED indication.

a text message without LED indication. This type of message is generally related to e.g. con-dition monitoring, alarms and warnings.

Fig. 5.-1. Protection indicators

5.1. Priority of indication and help messages

The messages in the assisting window have a certain priority. If different type of indicationsare activated simultaneously, the message with the highest priority appears on the display.The priority of the messages:

1. Internal fault2. Trip, CBFP3. Start, Block, Supervision 4. Help messages

The first latched and active indication (concerns messages 1 and 2) is shown in the assistingwindow according to the predetermined priority. The latest latched and active indication(concerns messages 3 and 4) is shown in the assisting window according to the predeter-mined priority

5.1.1. Help mes-sages

5.1.2. Indication messages

Indication messages (priorities 1-4) automatically gives an overview of indications of pro-tection and condition monitoring operations and internal protection relay faults. The indica-tions are shown in a priority order in the assisting window and the indication messages willbe active until acknowledged by pressing the C button for two seconds.

5.2. Protection indications

When one of the protection functions of the protection relay starts, the name of the corre-sponding protection function and the text ":START" are displayed in the assisting window.In the case of three-phase and two-phase protection functions, also the faulted phases aredisplayed. Also a yellow indicator LED is lit.

When the protection function started is blocked, the name of the corresponding function andthe text ":BLOCK" are displayed in the assisting window. Also a yellow indicator LED isblinking.

When the protection function trips, the name of the function and the text ":TRIP" are dis-played in the assisting window. Also a red indicator LED is lit. In the case of three-phaseand two-phase protection functions also the faulted phases are displayed.

When the protection function delivers a delayed trip for circuit-breaker failure protection,the name of the function and the text ":TRIP" are displayed in the assisting window. Also ared indicator LED is blinking. In the case of three-phase and two-phase protection functions,also the faulted phases are displayed.

5.3. Self supervi-sion (IRF)

The REF 54_ is provided with an extensive self-supervision system. The self-supervisionsystem handles run-time fault situations in the REF 54_ and informs the user about an ex-isting fault via an MMI and a LON/SPA communication.

The green READY indicator starts to blink when a fault has been detected. At the same timethe protection relay delivers a fault signal to the self-supervision output relay of the REF54_. Additionally, a fault indication text appears on the MMI of the REF 54_. Also, an eventE57 is generated to the serial communication (channel 0).

The fault indication text on the MMI consists of two constant rows as shown in the next ex-ample.

Fault indication has the highest priority on the MMI. Other MMI indications cannot overrunthe IRF indication. When the display panel has received a fault indication, the fault indica-tion text remains on the MMI. By pressing the C button for 2 seconds the fault indicationtext is cleared from the display, but the green LED remains still blinking. Blinking of thegreen READY indicator cannot be stopped.

In case an internal fault disappears, the fault indication text stays on the display, if it has notbeen cleared by the C button. The green READY indicator stops blinking and an alarm out-put IRF is released to normal service state. Also, an event E56 is generated to serial commu-nication (channel 0).

The fault code is stored and can be read from the main menu protection relay Status/General/IRF code. The IRF code includes the code of the first internal fault detected by the self-su-pervision system.

The fault code describes the type of internal fault in the REF 54_. When a fault appears, thecode should be recorded and given to the authorized repair shop when overhaul is ordered.

5.4. Condition monitoring indication

If the protection relay includes condition monitoring functions that are not directly relatedto any protection functions of the protection relay or to the internal condition of the protec-tion relay, they are indicated in the assisting window by the message SUPERVISION andan explanatory text.

5.5. Test modes There are various test modes for each of the following four categories: Function Control MIMIC I/O test

5.5.1. Function test

It is possible to activate the outputs of the function locally from the MMI or externally viathe serial communication. The outputs are activated by using control parameters of the func-tion.

For further details of functions, read the manual Technical Description of Functions.

5.5.2. Control test The system provides a general interlocking bypass mode (parameter Control/General/Inter/bypass) that overrides all interlocking signals. Activation of interlocking bypass mode acti-vates the interlocking enable signals of all control objects. Thus all control actions are pos-sible and enable signals of the controllable objects are not checked while the objects arecommanded. As long as the mode is active the interlocking LED in the MMI is red andblinking. Additionally the assisting window of the MIMIC view will indicate the specialcondition.

5.5.3. MIMIC test The test mode for MIMIC is entered by setting the Panel test parameter to start (1) in Mainmenu/ Tests/ Mimic [17] directory. The test can be interrupted by pressing any button. Ac-cordingly, the same Panel test is done as at power up (see chapter Display test at power up).

5.5.4. I/O test The test mode is for testing binary inputs and outputs and their effect on the function of theprotection relay. Entering the test mode for the inputs or outputs is done by setting the pa-rameter Test mode to Active in Tests/General at technical level. The user has to enter thetest mode before testing or else the changes will not be valid. The test mode can be cancelledby setting the Test mode parameter to Not Active or by power up.

Note! If the user forgets to cancel the test mode, it remains on and the READY LED remainsblinking.

5.6. Green indi-cator LED

Three different functions are embedded in the READY indicator.


Page 24

5.7. Yellow indi-cator LED

Steady LED: READY The LED is lit when the protection relay is in normal operation, i.e. no internal faults have occurred and an auxiliary voltage is available to the protection relay.

Blinking LED: IRF An internal protection relay fault (IRF) has occurred but an auxiliary voltage is connected. Also, if the pro-tection relay is in test mode, the LED is blinking. When an internal fault occurs, a message is received in the assisting window, provided the MMI/MIMIC panel is operative.

Non-active LED: OFF The auxiliary voltage supply to the protection relay has been disconnected

Check that the auxiliary voltage is discon-nected before taking any further action.

Table 5.6.-1 Green indicator LED functions

!

Non-active LED: OFF Normal operation mode. No function has started.

Steady LED: START A protection function is activated and the display shows the reason for starting. The start indication can be selected to be latching/non-latching. A non-latching type indicator automatically goes out when the fault disappears (the protection stage resets). A latching type indicator remains lit, although the fault disappears, until cleared by pressing the C button for two seconds.

Should several protection stages/functions start in a short time, the last start is indicated on the display.

Blinking LED: BLOCK The start LED goes on blinking as long as a protection function of the protection relay is blocked. The block-ing indication disappears when the blocking is removed or when the protection function in question is no longer started. Should the function still be started when the blocking signal is eliminated, the start indication will be activated. A message telling, which function has been blocked appears on the display. If several protec-tion functions are blocked at the same time, the most recent blocking is indicated on the display. If a protec-tion function is blocked when other protection func-tions are started, but not blocked, the LED remains blinking (Blocking has higher priority than start)

5.8. Red indica-tor LED

5.9. Interlocking Interlocking is used to inhibit the close or open command for a controllable object in certainsituations. The interlocking program of the REF 54_ operates according to the permissionprinciple, i.e. any control operations not enabled by interlocking are inhibited.

When an object is selected with the Select button, the assisting window shows the status ofthe interlocking program. The downmost LED of the programmable LEDs is reserved forthe interlocking function.

Non-active LED: OFF Normal operation mode. No trip function has operated.

Steady LED: TRIP A protection function has tripped. The trip indication is latching, i.e. the trip indication must be reset by press-ing the C button (or via the serial communication). If several protection stages/functions trip in a short time, the first tripping remains on the display.

Blinking LED: TRIP (CBFP) If the tripping is due to the CBFP (circuit breaker fail-ure protection), the red indication LED is blinking. The indication is reset by pressing the C button for 2 sec-onds.
