2. INTRODUCTION TO MiCOM

MiCOM is a comprehensive solution capable of meeting all electricity supply requirements. Itcomprises a range of components, systems and services from Schneider Electric.

Central to the MiCOM concept is flexibility.

MiCOM provides the ability to define an application solution and, through extensivecommunication capabilities, to integrate it with your power supply control system.

The components within MiCOM are:

• P range protection relays;

• C range control products;

• M range measurement products for accurate metering and monitoring;

• S range versatile PC support and substation control packages.

MiCOM products include extensive facilities for recording information on the state and

behaviour of the power system using disturbance and fault records. They can also providemeasurements of the system at regular intervals to a control centre enabling remotemonitoring and control to take place.

For up-to-date information on any MiCOM product, visit our website:

3. PRODUCT SCOPE

MiCOM P441, P442 and P444 Numerical Full Scheme Distance Relays providecomprehensive distance protection for different applications like: lines, cables, tapped lines,lines with multiple zero sequence sources, non-homogeneous lines, series compensatedlines and parallel lines.

The independently settable resistive reach for each zone allows easy application to shortlines and cable protection. Using well-proven, patented techniques to directionalise, andmaking full use of digital memory, the relays can be applied in situations that can causeclassic distance implementations to maloperate (crosscountry faults, close-up faults, etc.).

The MiCOM P441, P442 and P444 are in-built with a library of channel aided scheme logic,supplementary and back-up protection. It provides complete protection (4 alternative settinggroups) to solidly earthed systems from distribution to transmission voltage levels.

Three phase tripping with faulted phase indication is provided for all protection functions. Inaddition models P442 and P444 allow single-phase tripping for the distance protection andthe channel aided DEF protection (67N).

The P441, P442 and P444 distance relays equipped with 150MHz CPU and coprocessorboard have been enhanced as described in the following table:

1.2 Introduction to the relay

1.2.1 Front panel

The front panel of the relay is shown in the following figures, with the hinged covers at thetop and bottom of the relay shown open. Extra physical protection for the front panel can beprovided by an optional transparent front cover. With the cover in place read only access tothe user interface is possible. Removal of the cover does not compromise the environmentalwithstand capability of the product, but allows access to the relay settings. When full accessto the relay keypad is required, to edit the settings, the transparent cover can be unclippedand removed when the top and bottom covers are open. If the lower cover is secured with awire seal, this will need to be removed. Using the side flanges of the transparent cover, pullthe bottom edge away from the relay front panel until it is clear of the seal tab.

The cover can then be moved vertically down to release the two fixing lugs from theirrecesses in the front panel.

The fixed function LEDs on the left hand side of the front panel are used to indicate thefollowing conditions:

− Trip (Red) indicates that the relay has issued a trip signal. It is reset when theassociated fault record is cleared from the front display. (Alternatively the trip LED canbe configured to be self-resetting)*.

− Alarm (Yellow) flashes to indicate that the relay has registered an alarm. This may betriggered by a fault, event or maintenance record. The LED will flash until the alarmshave been accepted (read), after which the LED will change to constant illumination,and will extinguish when the alarms have been cleared.

− Out of service (Yellow) indicates that the relay’s protection is unavailable.

− Healthy (Green) indicates that the relay is in correct working order, and should be onat all times. It will be extinguished if the relay’s self-test facilities indicate that there isan error in the relay’s hardware or software. The state of the healthy LED is reflectedby the watchdog contact at the back of the relay.

To improve the visibility of the settings via the front panel, the LCD contrast can be adjusted

using the “LCD Contrast” setting with the last cell in the CONFIGURATION column.1.2.2 Relay rear panel

The rear panel of the relay is shown in Figure 3 (refer to section P44x/EN IN ‘Installation’ forterminals connections layout). All current and voltage signals, digital logic input signals andoutput contacts are connected at the rear of the relay. Also connected at the rear is thetwisted pair wiring for the rear EIA(RS)485 communication port, the IRIG-B timesynchronising input and the optical fibre rear communication port which are both optional. Asecond rear port (Courier) and an interMiCOM port are also available.

1.3 Relay connection and power-up

Before powering-up the relay, confirm that the relay power supply voltage and nominal acsignal magnitudes are appropriate for your application. The relay serial number, and therelay’s current and voltage rating, power rating information can be viewed under the tophinged cover. The relay is available in the following auxiliary voltage versions and these are

specified in the table below:

Nominal RangesOperative dc

RangeOperative ac

Range

24 - 48V dc 19 to 65V -

48 - 110V dc (30 - 100V ac rms) ** 37 to 150V 24 to 110V

110 - 250V dc (100 - 240V ac rms) ** 87 to 300V 80 to 265V

** rated for ac or dc operation

Please note that the label does not specify the logic input ratings. The P44x relays are fittedwith universal opto isolated logic inputs that can be programmed for the nominal battery

voltage of the circuit of which they are a part. See ‘Universal Opto input’ in the Firmwaresection for more information on logic input specifications. Please note that the opto inputshave a maximum input voltage rating of 300V dc at any setting.

Once the ratings have been verified for the application, connect external power capable ofdelivering the power requirements specified on the label to perform the relay familiarizationprocedures. Figure 2 and 3 indicates the location of the power supply terminals but pleaserefer to the wiring diagrams in the Installation section for complete installation detailsensuring that the correct polarities are observed in the case of dc supply.

1.4 Introduction to the user interfaces and settings options

The relay has thre following interfaces:

• the front panel user interface via the LCD and keypad.

• the front port which supports Courier communication.

• the rear port which supports one protocol of either Courier, Modbus,IEC 60870-5-103 or DNP3.0. The protocol for the rear port must be specified when therelay is ordered.

• the optional Ethernet, dual Ethernet or 9-2 Ethernet port(s),

• The optional second rear port wich supports Courier protocol.

The measurement information and relay settings which can be accessed from the threeinterfaces are summarised in Table 1.

1.5 Menu structu re

The relay’s menu is arranged in a tabular structure. Each setting in the menu is referred toas a cell, and each cell in the menu may be accessed by reference to a row and columnaddress. The settings are arranged so that each column contains related settings, forexample all of the disturbance recorder settings are contained within the same column. Asshown in figure 4, the top row of each column contains the heading which describes thesettings contained within that column. Movement between the columns of the menu is onlypossible at the column heading level. A complete list of all of the menu settings is given inthe manual.

FIGURE 4 - MENU STRUCTURE

All of the settings in the menu fall into one of three categories: protection settings,disturbance recorder settings, or control and support (C&S) settings. One of two differentmethods is used to change a setting depending on which category the setting falls into.Control and support settings are stored and used by the relay immediately after they areentered. For either protection settings or disturbance recorder settings, the relay stores thenew setting values in a temporary ‘scratchpad’. It activates all the new settings together, butonly after it has been confirmed that the new settings are to be adopted. This technique is

employed to provide extra security, and so that several setting changes that are made withina group of protection settings will all take effect at the same time.
