It is also used to programthe functionality of the opto-isolated inputs, relay outputs,LED and user alarms.The Programmable Scheme Logic can be used toimplement additional supervision features, such as tripcircuit supervision or implement complex logic such asfrequency restoration schemes. Schemes have beendeveloped capable of supervising the trip coil and circuitwith the circuit breaker open or closed.The Px40 gate logic includes OR, AND, NOT andmajority gate functions, with the ability to invert the inputsand outputs, and provide feedback. A number of generalpurpose logic timers are also available as well as thosetimers used to condition the relay contacts. The system isoptimized (event driven) to ensure that the protection outputsare not delayed by the PSL operation.The Programmable Scheme Logic is configured using thegraphical MiCOM S1 PC software, as shown in Figure 2The Px30 logic can be created using Boolean Equationsor a graphical interface as shown in figure 3.Figure 1> Independent Protection Settings GroupsUp to two setting groups are supported in the 20 Serieswhereas the 30 and 40 series can offer up to fourindependent setting groups. These can be activatedlocally, remotely or via a dedicated input and are used toallow for different system operating conditions and whereadaptive relaying is applied.> Measurement & Post Fault AnalysisFlexible logic for Px20The MiCOM Range of relays are capable of measuringand storing a wide range of system quantities such asCurrent, Voltage, Frequency, Power etc. depending on therelay functionality.All event, fault and disturbance records are time tagged toa resolution of 1ms using the internal real time clock andare stored in non-volatile memory. A supervised lithiumbattery ensures that the real time clock and records aremaintained during auxiliary supply interruptions.Where relays are communicating to a SCADA system,the protocols' telegrams can be used for external timesynchronization or alternatively an optional IRIG-B port isavailable for accurate time synchronization on all Px30and Px40 MiCOM relays.Some relays can also use an opto input to synchronizethe relay’s clock.Figure 2Programmable logic for Px40Figure 3Programmable logic for Px30

Power System MeasurementA comprehensive set of measurement values includinginstantaneous and derived values are available on therelays.These measured values can be displayed on the frontLCD display or transferred locally or remotely as per theuser requirements.POST FAULT ANALYSIS> Event recordsThese are generated for status changes to logic inputsand outputs, modifications to one or more settingparameters and alarm signals.All events are time-tagged and stored in chronologicalorder in a cyclic memory where the oldest record isoverwritten once the relay's maximum event count isexceeded. These are readily available for viewing on theLCD, or extraction via the communication ports.> Fault recordsAt least 5 records are supported on all relays and forevery fault, the following information is captured in therelay records• A fault number• The date and time• The active setting group• The function that issued the trip• The magnitude of the current/voltage that gave rise tothe trip command> Disturbance recordsThe internal disturbance recorder will record the sampledvalues of all analog input variables such as phasecurrents and voltages etc. where applicable during a fault.Oscillographic analysis can be performed usingMICOM S1 which will provide the means to quicklyanalyse analog and digital signals on the same time-scalefor convenience. Disturbance records can be extractedfrom the relay via the communication ports and saved inthe COMTRADE format.Figure 4Oscillography analysis using MiCOM S1 Softwarefor Optimum resultsRELAY COMMUNICATIONSAs standard, a front communication port is available forlocal access to the relay. An auxiliary rear communicationport is available as an option on relays providing anengineering port for easy access to settings, records andmeasurements for protection engineers. A main rearcommunications port is also available for interface to aSCADA system. A number of protocols are available asan option for this purpose.(See cortec code for each relay)Figure 5A typical substation control systemSCADAInterfaceMaster Clock(GPS)IRIG-BportModem(remote access)SCADA InterfacePx40EAI232(local access)Px30Px20Px20Mx20Px304>5

Local CommunicationThe front EIA(RS)232 communication port has beendesigned for use with the MiCOM S1 software and isprimarily for configuring the relay settings andprogrammable scheme logic. It is also used to locallyextract event, fault and disturbance record informationand can be used as a commissioning tool by viewing allrelay measurements simultaneously. In Px20 / Px30 thefront EIA(RS)232 is also used to upgrade relay software.In Px40 a separate front parallel port is used for this.215> Rear CommunicationThe rear communication port is based upon EIA(RS)485voltage levels and is designed for permanent multidropconnection to network control and data acquisitionsystems. An optional fiber optic communications port isalso supported on the 30 and 40 platforms.34In general, the following protocols are available atordering or via setting selection on the relays.• Courier/K-Bus• Modbus• IEC 60870-5-103• DNP3.0The following protocol is only available on Px30 / Px40relay models with an Ethernet port currently.• IEC61850Fig 5 illustrates the flexibility with which the MICOM rangeof relays can be integrated into a SCADA system as wellas provide engineering data for remote access by utilityengineers.USER INTERFACESThe user interface and menu text are available in English,French, German and Spanish as standard.Other languages such as for example Russian and Italianare supported on some relays depending on marketrequirements.The ability to customize the menu text and alarmdescriptions are also supported on Px30 and Px40.Figure 66Px40 series user interface110Figure 7Compact case user interfaceThe front panel user interfaces, as shown inFigures 6, 7 & 8 comprise:(1) A back-lit liquid crystal display (20, 30, 40 series)Graphic LCD display (30 series only)(2) Four fixed function LEDs (20, 40 series)Five fixed function LEDs (30 series)(3) Up to Four user programmable LEDs (20 series)Up to Eight user programmable LEDs (40 series)Twelve user programmable LEDs (30 series)(4) Menu navigation and data entry keys.(5) "READ" and "CLEAR" keys for viewing and reset ofalarms(6) An upper cover identifying the product name, whichmay be raised to view full product model number,serial number and rating information.(7) A lower cover concealing the front EIA(RS)232 port,download/monitor port and battery compartment.Cover not available on compact case.(8) Facility for fitting a security seal(9) Bay control keys up to 6 bays control (30 series)(10) Programmable Function keys(compact range and 30 series)3Figure 8Px30 series user interfacewith bay control2561542784User Language optionsthat provide true globalconvenience3789
