2. HEALTH AND SAFETY

For all the safety purposes please refer to the AREVA T&D Safety Guide: SFTY/4L M/F11(or later issue) andto the following chapters.

WARNING: THIS SAFETY SECTION SHOULD BE READ BEFORE COMMENCING

ANY WORK ON THE EQUIPMENT.

2.1 Health and Safety

The information in the Safety Section of the product documentation is intended to ensurethat products are properly installed and handled in order to maintain them in a safe condition.It is assumed that everyone who will be associated with the equipment will be familiar withthe contents of the Safety Section.

2.2 Installing, Commissioning and Servicing

Equipment connections

Personnel undertaking installation, commissioning or servicing work on this equipmentshould be aware of the correct working procedures to ensure safety. The productdocumentation should be consulted before installing, commissioning or servicing theequipment.

Terminals exposed during installation, commissioning and maintenance may present ahazardous voltage unless the equipment is electrically isolated.

If there is unlocked access to the rear of the equipment, care should be taken by allpersonnel to avoid electrical shock or energy hazards.

Voltage and current connections should be made using insulated crimp terminations toensure that terminal block insulation requirements are maintained for safety. To ensure thatwires are correctly terminated the correct crimp terminal and tool for the wire size should be

used.Before energising the equipment it must be earthed using the protective earth terminal, orthe appropriate termination of the supply plug in the case of plug connected equipment.

Omitting or disconnecting the equipment earth may cause a safety hazard.

The recommended minimum earth wire size is 2.5mm, unless otherwise stated in thetechnical data section of the product documentation.

When the protective (earth) conductor terminal (PCT) is also used to terminate cablescreens, etc., it is essential that the integrity of the protective (earth) conductor is checkedafter the addition or removal of such functional earth connections.

For M4 stud PCTs the integrity of the protective (earth) connection should be ensured by use

of a locknut or similar."

Before energising the equipment, the following should be checked:

Voltage rating and polarity;

CT circuit rating and integrity of connections;

Integrity of earth connection (where applicable)

Note: The term earth used throughout the product documentation is the direct equivalent ofthe North American term ground.

Equipment operating conditions

The equipment should be operated within the specified electrical and environmental limits.

Current transformer circuits

Do not open the secondary circuit of a live CT since the high level voltage produced may belethal to personnel and could damage insulation.


11/494



Insulation and dielectric strength testing

Insulation testing may leave capacitors charged up to a hazardous voltage. At the end ofeach part of the test, the voltage should be gradually reduced to zero, to dischargecapacitors, before the test leads are disconnected.

Insertion of modules and boards

These must not be inserted into or withdrawn from equipment whist it is energised since thismay result in damage.

Fibre optic communication

Where fibre optic communication devices are fitted, these should not be viewed directly.Optical power meters should be used to determine the operation or signal level of the device.


12/494



3. DECOMMISSIONING AND DISPOSAL

Decommissioning:

The auxiliary supply circuit in the MiCOM computers may include capacitors across thesupply or to earth. To avoid electric shock or energy hazards, after completely isolating the

supplies to the MiCOM computers (both poles of any dc supply), the capacitors should besafely discharged via the external terminals prior to decommissioning.

Disposal:

It is recommended that incineration and disposal to watercourses be avoided. The productshould be disposed of in a safe manner. Any products containing batteries should have themremoved before disposal, in order to avoid short circuits. Particular regulations within thecountry of operation may apply to the disposal of lithium batteries.


13/494



4. TECHNICAL SPECIFICATIONS FOR SAFETY

The recommended maximum rating of the external protective fuse for this equipment is 16A,High rupture capacity (HRC) Red Spot type NIT or TIA, or equivalent unless otherwisestated in the technical data section of the product documentation. The protective fuse shouldbe located as close to the unit as possible.

1. Fuse rating is dependent of auxiliary voltage and circuit loading.

2. Differential protective switch on DC power supply is recommended.

3. Differential protective switch on AC power supply is mandatory (printers, PACiSworkstation).

5. HANDLING OF ELECTRONIC EQUIPMENTS

A persons normal movements can easily generate electrostatic potentials of severalthousand volts.

Discharge of these voltages into semiconductor devices when handling circuits can cause

serious damage, which often may not be immediately apparent but the reliability of the circuitwill have been reduced.

The electronic circuits of AREVA T&D Energy Automation & Information products areimmune to the relevant levels of electrostatic discharge when housed in their cases. Do notexpose them to the risk of damage by withdrawing modules unnecessarily.

Each module incorporates the highest practicable protection for its semiconductor devices.However, if it becomes necessary to withdraw a module, the following precautions should betaken in order to preserve the high reliability and long life for which the equipment has beendesigned and manufactured.

1. Before removing a module, ensure that you are a same electrostatic potential as theequipment by touching the case.

2. Handle the module by its front-plate, frame, or edges of the printed circuit board. Avoidtouching the electronic components, printed circuit track or connectors.

3. Do not pass the module to any person without first ensuring that you are both at thesame electrostatic potential. Shaking hands achieves equipotential.

4. Place the module on an antistatic surface, or on a conducting surface, which is at thesame potential as you.

5. Store or transport the module in a conductive bag.

More information on safe working procedures for all electronic equipment can be found inIEC 60147-0F and BS5783.

If you are making measurements on the internal electronic circuitry of any equipment inservice, it is preferable that you are earthen to the case with a conductive wrist strap.

Wrist straps should have a resistance to ground between 500k 10M Ohms. If a wrist strapis not available you should maintain regular contact with the case to prevent the build up ofstatic. Instrumentation which may be used for making measurements should be earthen tothe case whenever possible.

AREVA T&D Energy Automation & Information strongly recommends that detailedinvestigations on the electronic circuitry, or modification work, should be carried out in aSpecial Handling Area such as described in IEC 60147-0F or BS5783.

6. PACKING AND UNPACKING

All MiCOM C264/C264C computers are packaged separately in their own cartons andshipped inside outer packaging. Use special care when opening the cartons and unpackingthe device, and do not use force. In addition, make sure to remove from the inside carton thesupporting documents supplied with each individual device and the type identification label.

The design revision level of each module included with the device in its as-deliveredcondition can be determined from the list of components. This list should be carefully saved.

After unpacking the device, inspect it visually to make sure it is in proper mechanicalcondition.

If the MiCOM C264/C264C computer needs to be shipped, both inner and outer packagingmust be used. If the original packaging is no longer available, make sure that packaging

conforms to ISO 2248 specifications for a drop height 0.8m.

3. INTRODUCTION TO MiCOM APPLICATIONS

AREVA philosophy is to provide a range of computers, gateways and IEDs products. Each ofthese products can be used independently, or can be integrated to form a PACiS system, aDigital Control System (DCS) or a SCADA system.

3.1 MiCOM Computers

Driven by the requirements around the world for advanced applications in SCADA, DigitalControl Systems, Automation, control and monitoring, AREVA has designed and developeda complete range of computer products, MiCOM C264 specifically for the power processenvironment and electric utility industry. It allows building a personalised solution for Control,Monitoring, Measurement and Automation of electrical processes.

MiCOM C264/C264C computers range are designed to address the needs of a wide rangeof installations, from small to large and customer applications. Emphasis has been placed onstrong compliance to standards, scalability, modularity and openness architecture. Thesefacilitate use in a range of applications from the most basic to the most demanding. Theyalso ensure interoperability with existing components and, by providing building computers,

PLC or IEDs approach, provide a comprehensive upgrade path, which allows PACiScapabilities to track customer requirements.

Key features are that this computer family is based on a Ethernet client/server architecture,its a modular computer that offers a large variety of applications such as Bay Computer,Remote Terminal Unit and Programmable Logic Controller.

Phase in time, dedicated computer available for each application will be purposed.

3.2 Applications and Scope

The MiCOM C264/C264C modular bay controller, RTU or PLC is used to control and monitorswitchbays. The information capacity of the MiCOM C264/C264C is designed for controllingoperated switchgear units equipped with electrical check-back signalling located in medium-

voltage or high-voltage substations.External auxiliary devices are largely obviated by the integration of binary inputs and poweroutputs that are independent of auxiliary voltages, by the direct connection option for currentand voltage transformers, and by the comprehensive interlocking capability.

This simplifies handling of bay protection and control technology from planning to stationcommissioning. During operation, the user-friendly interface makes it easy to set the unit andallows safe operation of the substation by preventing non-permissible switching operations.

Continuous self-monitoring reduces maintenance costs for protection and control systems.

A built-in liquid crystal display (optional front face with LCD) shows not only switchgearsettings but also measured data and monitoring signals or indications.

The bay is controlled interactively by using the control keys and the display.

Adjustment to the quantity of information required is made via the PACiS SystemConfigurator Editor (PACiS SCE).

The MiCOM C264/C264C can be connected to a higher control level, local control level orlower levels by way of a built-in communications interface.

2. MiCOM C264/C264C MANAGEMENT

2.1 Operating mode management

2.1.1 Definitions

The terms defined below are used in this whole section 2.

Anomaly: an anomaly is a fault causing a downgraded behaviour of the computer.There are hardware and/or software anomalies:

Board failure

Loss of synchronisation

Loss of communication

Software fault: A software fault results of a major software error. In this case thecomputers enters the Faultymode.

Vital harware fault: a vital hardware fault is a fault causing a software halt. This kindof fault causes the computer to stop the application software.

CPU fault

Power supply fault

Bus fault

Permanent Interruption fault

2.1.2 Initialisation mode

After power on or manual reset the computer enters the initialisation mode and performs

different types of checks:

Vital hardware tests

Non-volatile memory test: in case of a problem the computer tries to repair this non-volatilememory. If a vital hardware test fails, the initialisation is stopped and the computer enters theHaltmode.

Non vital hardware tests

Non-vital hardware tests are only performed on present boards:

Inputs and outputs boards:

To determinate the number and the type of the present input and outputboards

To check the presence of the previously input and output boards and to beinformed if a board is absent

To check the good working order of the present input and output boards andto be informed if a board is out of order

Communication boards: this test is performed within the communication protocol.

Display (LCD, LEDs): the single test that can be done is the presence of the HMIboard.

Peripheral devices (printer, external clock ..). Check of the presence of the devicesby use of timeouts.

If any of these non-vital hardware tests fails the computer enters theoperational/downgradedmode depending on the type of the fault.

Software tests (database coherency tests)


62/494



These tests are performed at each restart of the computer. The checks of the databaseguarantees that the database is compatible with the hardware and the software of thecomputer and that it does not contain incoherent data of configuration. The following checksare performed:

Check of the presence of a database

Check of the DB/ software compatibility

This control makes it possible to check that the software and the database arecoherent. The computer contains in its static data a version and a revision numberindicating which structure of database it is able to interpret. The database must havethe same version to be accepted.

Check of the DB/ equipment compatibility

This control makes it possible to check that the database is intended for theequipment on which it was downloaded. To check it, the type and the number ofequipment contained in the heading of the database are compared with the type andthe number of equipment contained in the static data of the software.

Check of the validity of the data of the database

This control checks that the configured inputs and outputs are present and that thenumber of objects (bays, digital inputs ) remains within acceptable limits.

If any of these checks fails, the computer enters the Maintenancemode.

The initialisation of the computer does not exceed one minute.

2.1.3 Operational mode

This mode can be divided into two sub-modes: Normal mode and Downgradedmode.

2.1.3.1 Normal mode

This is the nominal operating mode of the active computer. In this mode the watchdog relayis activated and all the functionalities of the computer are available. Nevertheless, detectionof an error can lead to the Downgradedmode, to the Faultymode or to the Halt mode,depending on the nature and the gravity of the failure.

From this mode a transition to the Maintenancemode can be requested by an operator fromlocal HMI or upper level (maintenance request).

From this mode a transition to the Testmode can be requested by an operator from localHMI or upper level (simulation request).

In this mode, the operations that can be done on databases are the following:

Download a standby database Swap the databases: then the computer automatically restarts

Modify a database

Display database information

This mode is transmitted to local HMI and upper level (RCP).


63/494



2.1.3.2 Downgraded mode

This mode is entered in case of an anomaly. In this mode the general working of thecomputer is not very disturbed because it involves the degradation of only few functions. Thewatchdog relay is activated.

The downgraded mode depends on the hardware configuration of the computer. But we can

define the different kinds of downgraded modes that can happen:

Operation without DO on a board

Operation without DI on a board

Operation without AI on a board

Operation without communication with some relays

Operation without communication with some station devices

A combination of two, or more, of these previous items

When the cause(s) of the transition into Downgraded mode disappear(s), the computerreturns to the Normalmode.

2.1.4 Maintenance mode

In Maintenancemode, communication on the station bus is operational in order to managethe database. This mode is displayed on local HMI (led and LCD) and on upper level.

The watchdog relay is de-activated.

In this mode the operator can manage the database:

Download a database

Swap the databases

Modify a database

Display database information

From this mode a transition to the operationalmode can be requested by an operator fromlocal HMI or upper level (active request).

2.1.5 Test mode

In Testmode, the computer works normally but output relays are not activated. This mode isentered on operator request in order to simulate the functioning of distributed automatismssuch as interlocking. Instead of activating the output relays, the computer sends a test OKmessage to the SCP if the command is valid otherwise a test NOK message.

NOTE: to realise the tests, the operator has to manually create the testingconditions by forcing BI or Measurements on different computers.Once the conditions are realised, he can generate a command andsee at the SCP level (HMI) if the result corresponds to the expectedone.

This mode is displayed on local HMI (led and LCD) and on upper level.

From this mode a transition to the operationalmode can be requested by an operator fromlocal HMI or upper level (end of simulation).


64/494



2.1.6 Faulty mode

The Faultymode is entered when a fault, that prevents the exploitation, happens. This modecan be entered from any mode described above.

This mode is also entered when a failure is detected on DO boards and if the configuration

allows this mode on DO faults.The only way to leave this mode is an automatic reset or a transition to the Haltmode. Eachtime the computer enters this mode, an internal counter is incremented. As long as the valueof this counter is lower than Max_Fault (parameter defined during the configuration step) theInitialisation mode is entered. The value of this counter is automatically reset when thelasted time since the last incrementation of the counter reaches the valueFault_Detection_Lasting (parameter defined during the configuration step). When the valueof this counter reaches Max_Fault the computer enters the Haltmode.

2.1.7 Halt mode

In this mode the computer doesnt operate anymore. The watchdog relay and all the outputsrelays are deactivated. The only way to get out of this mode is to operate a manual reset.

The following figure summarises the different operating modes of the computer and thetransitions.

2.2 Database management

The MiCOM C264/C264C uses structured databases for data management. A database(DB) is a file which contains the description of the whole of the electric process, as of thewhole of the equipment which the computer is likely to dialogue with (IED, HMI ,etc.). Itcontains also some parameter settings of the software and of the transmission. Databases

are generated and versioned by an independent equipment: the System Configuration Editor(SCE). Each database file has an associated Vdbs(System Baseline Version) A database isdownloaded into the non-volatile memory of the computer via the IEC61850 station bus withthe System Management Tool (SMT) or directly over Ethernet with the ComputerMaintenance Tool (CMT).

The computer stores at any moment up to two DBs in its non-volatile memory. The two DBs(and these associated V

dbs) are called thereafter DB1 and DB2 (and these associated V

dbs1

and Vdbs2).

Each database (DB1 and DB2) of the computer can take one of the following states:

Missing: the DB is not present in non-volatile memory of the computer;

Standby: the DB was downloaded in non volatile memory of the computer; however,this version is not taken into account by the software;

Current: the downloaded DB is taken into account by the software;

Current Modified: the DB, currently taken into account by the software, underwent aparameter setting;

Standby Modified: the DB underwent a parameter setting, but it is not taken anymore into account by the software.

The following diagram represents the life cycle of the databases in the computer:

FIGURE 3: THE DIFFERENT STATUS OF A DATABASE

At any moment, there is only one Currentor Current Modifieddatabase. In the same way,there is only one Standbyor Standby Modifieddatabase.

A file descriptor (DB context) stored in non-volatile memory contains the configuration of theDB present on the equipment. This file, containing the state of each of the two databases

(DB1 and DB2) and the Vdbs (Vdbs1 and Vdbs2) of each one, makes it possible to know theconfiguration of the databases at the moment of the boot, and to start again with the currentdatabase (if it exists). DB Context is updated by the sub-functions "Download a database","Switch the databases", "Check a database", "Modify a Database".


66/494



To download a database ( via Ethernet)

The downloading of a database is usually performed with SMT tool via the station bus.

The first downloading of a database (and its associated Vdbs) can be performed onlywhen the computer is in maintenance mode.

The downloading of a standby database (and its associated Vdbs) can be performedwhen the computer, running with the current database, is either in operational mode orin maintenance mode.

The sequencing is:

To work out and transmit to the calling equipment a response to the request: therequest can be refused if another request on database is already in progress;

To carry out the transfer of the DB file (and associated Vdbs) and to check itsintegrity (calculation of checksum and control of the database);

In case of fault, to announce to the calling equipment the failure of the transfer;

In case of successful transfer, to control the database compatibility;

In case of invalid DB, to announce to the calling equipment the failure of theinstallation;

In case of valid DB, to assign to the downloaded database (and associated Vdbs)the state standby by removing a possible standby database (and associatedVdbs) present in the computer; to signal to the calling equipment the success ofthe installation;

To update the file descriptor (Context database) in non-volatile memory.

To switch the databases

This function answers to a request of DB switching coming from the station bus. Thisrequest specifies the Version of the standby DB (Vdbs) to become current. Aftera DB switch the computer automatically reboots and goes into active Mode if the DB iscoherent with the software.

To modify the database

The parameter setting of database consists in modifying some values of configurationpresent in the database. A parameter setting can be carried out only on the currentdatabase (Currentor Current Modified). Following a parameter setting, file database ismodified: the new value taken by the data is memorised there. The index of parameter

setting of the database is incremented, and the checksum of the file is recomputed.The database then takes the Current Modified state. Only certain data are settable.This is performed from the local HMI.

To carry out a parameter setting of data

This function treats the requests of parameter setting:

To check the coherence of the request: known object (the object is reallypresent in the database), settable data, value of parameter setting compatiblewith the type of data conveyed (value belonging to the range of acceptablevariation),

If the request is incoherent, to emit a negative report to the emitter of the

request,

To write in database file the current value of the data,

To write in database file the date of modification of the data,

To compute the checksum and to write it in data base file,

To assign the state Current Modifiedto it,

To emit a positive report with the emitting equipment of the request,

To update the file descriptor (Context database) in non-volatile memory.

To consult a settable data

This function treats the requests of consultation of parameter issued from the OperatorStation:

To check the coherence of the request: known object (the object is quite present inthe database), settable data and currentDB

If the request is incoherent, to emit a negative response to the transmitter of therequest

To work out the response to the transmitter of the request by giving the currentvalue of the data

2.3 Time managementThe main purposes of the time management are:

Synchronisation of the computer by:

The external clock

Station/legacy bus

Operator

Updating of the internal clock

Synchronisation of other equipments via station bus

Time synchronisation of a computer can be done by four means:

External clock (IRIG-B signal

Clock message from a SCADA gateway (T-Bus)

Clock message from the system master clock (S-Bus)

Time set by an operator


68/494



Concerning these four external time references, there is a priority rule: if the external clock isoperating, modifications on the computer clock are not possible by other ways (for examplefrom SCADA gateway, system master clock or operator). In case of external clock isdisconnected or not operating, there is a priority order: clock message from a SCADAgateway or from the system master clock takes priority over operator.

When the computer is master of legacy bus, it synchronises the IED according to thesynchronisation procedure of the protocol. The synchronisation is done just after thecomputer has been synchronised by external clock or station bus or RCP. If the computer isnot synchronised, it synchronises periodically the IED all the same.

When the computer is synchronised all events and measurements have a time tag withsynchronised attribute. If synchronisation is lost, or has never been received attributesindicates that time tag is not synchronised.

The time management organisation is based on the following scheme:

C0004ENc

External clock

Which synchronisesthrough station bus

FIGURE 5: TIME MANAGEMENT

2.3.1 External clock

A computer gets functionality of system master clock: it is the architecture equipment whichreceives periodically, from an external IRIG-B clock reference, messages containing the dateand the hour.

The external clock device receives the synchronisation signal through several possibleprotocols (GPS, DCF77, etc) and then sends it periodically to the dedicated IRIG-B inputof the MiCOM C264/C264C.

The external clock transmits to the computer the hour and date that itself receives.

In case of loss of the radio signal by the external clock two cases have to be considered:

1. Some external clocks can synchronise the computer for 8 hours after loss of radiosignal because they have an oscillator with a very good accuracy. The external clockindicates via the protocol two informations: no radio received and loss radiosignal since more 8 hours. The computer remains synchronised until the indicator"loss radio signal since more 8 hours"is activated. Then the status of internal clock

becomes not-synchronised.

2. Some external clocks haven't internal accuracy circuit to back up the radio signal. Inthis case, the status of internal clock of computer becomes not-synchronisedafterconfirmation of loss radio signal(few minutes).


69/494



If the computer is master clock for the other equipment of the substation then it sends thesynchronisation message to the other equipment even if it is not synchronised. In this same,it stays synchronised even if it loses the external clock communication. A dedicated binaryinput is associated to the external clock status.

2.3.2 Clock message from a SCADA gateway

SCADA clock acquisition is a SCADA gateway specification. The purpose of this part is todetail acquisition of clock message from SCADA gateway.

SCADA clock synchronisation depends on the protocol. The synchronisation message isdirectly acquired by the MiCOM C264/C264C through the SCADA link.

The clock message from SCADA gateway is in UTC time.

The SCADA clock to local clock update function. This clock is transmitted after acquiredframe from the SCADA gateway has been checked and its control fields removed.

When the acquisition of clock message from SCADA gateway is operating (depending on thepriority), the computer receives a clock synchronisation message from the SCADA. Aninterruption is related to the frame arrival and clock message from SCADA gateway can be

acquired. The delay transmission from SCADA gateway is compensated.Whatever the protocol, clock message from SCADA gateway must contain:

Day / month / year / hour / minutes / seconds / milliseconds

The update of computer internal clock upon the clock message from SCADA gateway ismanaged as specified in local clock update function.

2.3.3 System master clock

On an IEC61850 network, time synchronisation is based on SNTP ( Simple Network TimeProtocol). In a PACiS system up to two computers can be defined as System Master Clockand so are SNTP servers. All others IEC61850 equipment are SNTP clients. In case offailure
