Like its predecessor, it features the following functions:ProtectionMeasurementControlMonitoringAll functions mentioned above and power quality functions are integrated in a programmable environment. The exceptional flexibility and scalability of these newgeneration devices lead to a smart and clean solution where the traditional approach would be ineffective and expensive.The following figures show examples of the REF542plus installation in several switchboards.Figure 1: REF542plus installed in gas insulated switchboards (GISFigure 2: REF542plus installed in an air insulated switchboard (AISThe REF542plus is based on a real-time microprocessor system. The measurement and protection functions are executed by a D igital S ignal P rocessor (DSP, while a M icroC ontroller (MC is executing the control functions. Due to this task separation there is no impact between the start and the trip behavior of the implemented protection scheme, should the control scheme be modified. The C ommunication P rocessor (CP is needed for connection to a station automation system. A block diagram of theREF542plus isshown in figure 3.Figure 3: REF542plus Block diagramREF542plus, as shown in figure 3, consists of two parts, a Central Unit and a separate H uman M achine I nterface (HMI. The Central Unit contains the power supply, processor and analog and binary I nput and O utput (I/O modules, as well as optional modules for supplementary functions.The HMI Control Unit is a stand-alone unit with its own power supply. It can be installed on the L ow V oltage (LV compartment door or in a dedicated compartment close to the Central Unit. The HMI is normally used to set the protection parameters and to locally operate the switching devices in the switchbay. The HMI is connected to the Central Unit by a shielded, isolated twisted pair according to the RS485 interface. Figure 4 shows an installation of the Central Unit and the HMI Control Unit in the LV compartment of a switchboard for the switchbay.Figure 4: Mounting of the Central Unit in the LV compartment and the HMI on the doorThe HMI Control Unit, as shown in figure 5, features a back-illuminated L iquid C rystalD isplay (LCD, eight push buttons, several LEDs and an electronic key interface. The language of the display can be selected via the related configuration software tool, which is also used to define the protection and the control scheme.Figure 5: The HMI Control UnitThe left half of the LCD display is reserved for the Single Line diagram. The right half is used to display the appropriate menu or submenu as determined by the user. Two different electronic keys with different access rights are available. Each of the keys are programmed to permit either:protection functions parameterization of themode selection of the control functionsThree freely programmable LED bars have been provided on the front of the HMI Control Unit. Each LED bar consists of ten green and two red LEDs and is user configurable to display any required measurement value. The red LEDs are used to indicate values above the rated value.The functions of the REF542plus can be tailored to the system requirements via a user-specific configuration. The user-specific configuration is loaded during commissioning. For that purpose the configuration computer, normally a personal computer (notebook running Windows NT, is connected to the optical interface on the front side of the HMI Control Unit.The interface of the multifunctional unit REF542plus to the M edium V oltage (MV primary process is as follows:Analog inputs to measure current and voltage signals from instrument transformers or non conventional sensorsBinary inputs with optical couplers for the galvanic separation of the external signals to be processed;Binary outputs with conventional mechanical relays or static outputs for the control of switching devices;Optional four channel analog outputs 0 to 20mA or 4 to 20 mAOptional connection to ABB or third party station automation system.REF542plus is a certified product for compliance to the Industrial IT architecture concept of ABB.Industrial IT products can be effectively combined together into value-added systems and solutions in a “Plug&Produce” manner.Compliance according to “Level 0: Information” ensures that all relevant product documentation – including the operation manual, instructions for installation and maintenance, electrical and mechanical drawings, test reports and specific order information -is online available, in electronic format, for access via software products and systems based on the ABB Aspect Integrator Platform.In this way, significant benefits are enabled to the final user for much easier and effective installation, configuration, operation and maintenance of the product in the plant. Detailed information on Industrial IT is available at /industrial it2 FunctionsREF542plus Multifunction Protection and Switchbay Control Unit integrates all thesecondary functions in a single unit. This multifunctional unit also features a self-monitoring function. All functions are designed as freely configurable software modules.Therefore, a wide range of operation requirements in MV stations can be met without any problems. The versatility of the software makes it possible to use theREF542plus on every switchboard independent on the specific application required.2.1 ConfigurationEach application for protection and control can easily be configured by software function modules, which make arbitrary definition of the following features as part of the secondary system possible:LED's (meaning and colors for local indicationSingle Line diagram to show the status of switching devicesProtection schemesControl schemesInterlocking schemesAutomation sequencesAll functions in the switchbay can be specified in collaboration with ABB. The result of the configuration is saved and delivered together with the switchboard to the users. By using the "FU nctional block P rogramming La nguage” (FUPLA theREF542plus Multifunction Protection and Switchbay Control Unit offers engineers, especially those who are not software experts, the opportunity of easily updating the operation and handling of the switchbay.With REF542plus the user has the benefit of a secondary system that is fully integrated ina true programmable controller. This flexibility is very advantageous for defining controlfunctions for automation sequences, which can, for example, include the interlocking of the switching devices, blocking the release of specific protection functions, as well as starting switching sequences.REF542plus multifunctional unit provides a wide range of logical functions so that each required control schemes can be configured. The range of logical functions includes: AND logic gateNAND logic gateOR logic gateNOR logic gateXOR logic gateBistable and monostable flip flopCountersTimersPulse generatorsMemoriesSimilar to the free definition of the control scheme, each required protection scheme can be configured by the combination of the available protection function modules. Forexample, the following protection functions areavailable:Definite time overcurrent protectionInverse time overcurrent protectionDirectional overcurrent protectionUnder- or overvoltage protectionDistance protectionDifferential protection for transformer and motorThermal protection for cable, transformer and motorReverse power protectionSynchronism checkNote The specific software configuration of the required protection scheme can only be carried out in-house at ABB.The protection scheme parameters can be changed via the HMI Control Unit withoutusing a personal computer. Additional functions can be excuted with a personal computer running the configuration software and connected to the optical interface on the front of the HMI unit.These additional functions are:Parameterization of the protection scheme,Read-out of the current measurement values,Read-out of the status of the binary inputs and outputs,Read-out of the fault recorder andViewing of the FUPLA logic I/O states2.2 OperationA wide range of functions can be controlled and operated using the simple, user-friendlyinterface on the HMI Control Unit. This user-friendly interface is shown in the following figure.Figure 6: HMI as Control UnitThe HMI consists of the following features:2.2.1 LCD displayThe back-illuminated LCD display of the HMI provides a graphical display of the switching devices in the switchbay controlled by the REF542plus. The intensity and the duration of the illumination can be set as required. The Single Line diagram shows the current status of all the switching devices. The right half of the LCD display is for plain text, such asmeasurement values, main menu and submenus descriptions, protection signals and event recording.On the LCD display, the following can be shown:Up to eight switching device icons (when the binary I/O boards with mechanical relays are used, a maximum of seven switching devices can be controlledVarious icons for motors, transformers, sensors, transducersA maximum of 40 individual lines.2.2.2 Status IndicationFour system LEDs, describe in the following chapters, indicate the status of theREF542plus.2.2.2.1 Operational statusOn the HMI front panel, the operational status is called 'Ready' and is displayed by agreen LED. The unit is not operational when this LED is off, and this occurs for example during the downloading of the configuration for the operation of the switchbay or if a fault condition is detected in the Central Unit.2.2.2.2 Communication statusOn the HMI front panel, this communication status is called 'Network Communication'. If the REF542plus is to be connected to a station automation system, the appropriatecommunications board is required. In this case a green LED is used to indicate thecorrect operational status of this optional board. The LED color changes to red if acommunication failure has occurred.2.2.2.3 Alarm indicationSeveral arbitrary alarm conditions can be defined and configured by the user. If one of these conditions is fulfilled, the red LED will be on.2.2.2.4 Interlocking statusThe LED is green if no interlocking conditions have been violated. In case of a switching action, which violates the interlock conditions such as switching a disconnector in theclosed condition of the C ircuit B reaker (CB, the color will change temporarily to red.2.2.3 LED IndicationEight freely programmable, three color LED's are provided for local indication. Thenumber of LED display options can be quadrupled through the menu structure. As aresult, a total of 32 indication options are available for status indication regardingprotection, control, monitoring and supervision functions.2.2.4 Bar displaysThree freely programmable LED bars are provided for showing the measurement values.The LED bars are used to display arbitrary measurement values as required. Each bar consists of ten green and two red LEDs. The nominal values of each LED bar, whichcorresponds to the ten green LEDs are defined by the configuration software. If themeasurement values are higher than the rated values, the red LEDs will gets illuminated indicating an overload situation.2.2.5 Control push buttonsThe control push buttons are used for operation of the switching devices during localcontrol. A total of eight push buttons are available, four for commanding the primaryequipment and four for browsing the display. The emergency push button can beconfigured in the FUPLA to open the circuit breaker when pressed simultaneously with the normal open push button.2.2.6 Electronic keyTwo different electronic keys are provided. One key can only be used for the protection scheme parametrization. The other one is for control modes selection: local, remote or local/remote. By using these two keys a certain separation between protection and control operation can be achieved. If required a general key that permits access to both modes is provided. The sensor for recognizing which electronic key has been used is located on the front panel of the HMI Control Unit.2.3 MeasurementREF542plus can have a maximum of 8 analogue input channels for measuring current and voltage signals. These channels are organized into three groups.Group 1 and group 2 have to be homogeneous, that means they can measure 3 currents or 3 voltages. For example, measurement of 1 current and 2 voltages is not allowed.Group 3 can get any type of signals: 2 currents, 2 voltages, 1 current and 1 voltage, etc.Channel 8 in the current REF542plus release can be used for measurement purposes only (no protection. REF542plus analogue inputs are very flexible, as this flexibility is needed to support all the protection functions of the unit itself.Group1 and group 2 can be used for homogeneous current or voltage measurements both from instrument transformers and non conventional sensors. Group 3 can be used ina heterogeneous way, as well with instrument transformers as also with sensors. Channel7 in group3 can be used for earth fault current with current transformer type input; or forthe synchronism check function with voltage transformer type input.The most common configuration uses three current and three voltage inputs and oneearth fault current input. All values are shown on the display as primary values. Thevalues registered over an extended time period, for example energy, number of CBoperations, maximum and measurement values are permanently saved. Even after power interruptions this data is still available. Using this common configuration, the following measured values are displayed:2.3.1 Values measured directlyLine currents, three phasesPhase voltages, three phasesEarth current or residual voltageFrequencyFrom the above measured quantities the following values can be calculated:2.3.2 Calculated valuesLine voltages, three phasesEarth current or residual voltageAverage value/maximum value current, three-phase (determined over several minutesApparent, active and reactive powerPower factorActive and reactive energyMoreover, the following quantities for monitoring purposes can be provided:2.3.3 Other valuesOperating hoursSwitching cyclesTotal switched currentsMetering pulses from an external metering device (up to 102.4 ProtectionThe REF542plus offers a wide range of functions for protection. As mentioned before, a wide range of protection schemes for the protection of several system components can be configured. The available protection functions can be combined together to form the required protection scheme. Figure 7 shows an example of a configured protectionscheme.Figure 7: FUPLA protection scheme2.5 ControlThe REF542plus permits convenient local operation with full interlocking againstswitching errors. The switch position of the various switching devices in the switchbay can be shown on the LCD display of the HMI Control Unit. If local control mode is selected, switching actions can be input locally using the control push buttons on the HMI Control Unit. Switching to another control mode can only be achieved by using the correctelectronic key.In remote control mode, only switching actions from a remote control unit like a station automation system are feasible. A special control mode, Local and Remote, is provided for users who want to perform simultaneous Local and Remote switching.Interlocking between the switchbays connected to the same bus bar system can also be taken into account. This requires the availability of status information of the switching devices to and from other switchbays. The status information must be provided either bya conventional, hard wired ring bus system or by the more sophisticated ABB stationautomation system. Figure 8 shows an example of a configured control scheme of the CB.Figure 8: FUPLA control scheme2.6 Event recordingThe last 30 recorded events can be shown locally on the LCD display of the HMI unit. The events are mostly related to protection activities. As well as displaying the event name, additional information about the event, time, date and the RMS value of the short circuit current switched off by the CB are provided. Each event is stamped with the time and date. The time is taken from the internal clock on the REF542plus, which can besynchronized by the station automation system. In the next figure, a list of recordedevents is shown.Figure 9: Event list on the LCD of the HMI2.7 Fault recordingThe multifunctional unit REF542plus is equipped with a fault recorder module, which record and encode analog and binary data. The number of recorded data channelsdepends on the initial configuration. Up to seven signals of the analog channels and 32 binary signals can be recorded. The analog input signals are recorded with a sampling rate of 1.2 kHz for a period of at least 1-second and for a maximum of 5 seconds. The recording time is a combination of pre- and post fault time. The records are saved using a typical ring buffer process, i.e. the oldest fault record is always overwritten with a new one. The number of saved fault records depends on the record time. For example, a maximum of 5 fault records can be saved with a recording time of 1s.Fault records can be exported and converted by the configuration software. The transfer of fault records can be done also via the interbay. Figure 10 shows a record of a cross country fault in an earth fault compensated MV system starting with the earth fault.Figure 10: Record of a cross country fault in an MV system2.8 Real time clockREF542plus is equipped with an internal real time clock which is used to time stampevents. The internal clock is buffered by a special super capacitor. In case of DC power supply failure, the stored electrical energy in the capacitor ensures continued operation of the internal clock for at least another two hours. The date and time of the clock can be set via the HMI Control Unit.REF542plus internal clock can be kept synchronized with an external clock in different ways.When connected to a station automation system, REF542plus is synchronized viainterbay bus using the facilities of the used protocol. If better accuracy is required,REF542 plus can be synchronized using the dedicated IRIG-B optical input port and a GPS master clock.Figure 11: Synchronization of the internal clock by a GPS master clock2.9 Process interfaceAn interface to the primary process is needed to carry out the protection, measurement and control schemes. The process interface will be described in the following paragraphs: 2.9.1 Analog inputsThe REF542plus Multifunction Protection and Switchbay Control Unit is designed forconnection to non conventional current and voltage sensors as well as to instruments transformers. Thanks to their linear characteristic, modern current and voltage sensors provide greater accuracy and reliability in signal measurement. Compared to instrument transformers, the new sensors have the following advantages:High accuracyCompact dimensionsWide dynamic rangeEasy integration in the switchboardThe current sensor is based on the principle of the Rogowski coil and consists of a single air-cored coil. Due to the lack of an iron core, the saturation effects of conventional current transformers do not exist anymore. Current sensors are thus well suited for the deployment of distance protection and differential protection functions.The current sensor measures the current value using a voltage signal that is proportional to the derivative of the primary current being measured. The numerical integration of the signal is performed using the DSP in the REF542plus unit. The current sensors cover a range from 0.5 to 2.0 of the rated current. The 80 A current sensors are for example very suitable for applications between a current range of 40 A to 160 A.The voltage sensor is based on the principle of the resistive divider from which the signal is obtained and is of a type that cannot be saturated. Therefore, the voltage sensor is linear throughout the measuring range. The output signal is a voltage that is directly proportional to the primary voltage. The next figures shows the combined sensors. Thecurrent and voltage sensors are encapsulated into a single resin unit, and that is the reason why they are referred as combined or combi sensors.Figure 12: Combined sensorA capacitive divider is incorporated in the combined sensor to provide the power supply for voltage presence indicator lamps.The output signals of the current and voltage sensors are connected directly to the Central Unit of the REF542plus, they do not require adaptation transformers. By using either modern sensors or conventional measurement transformers, the accuracy class 1 can be fulfilled, on condition that the current and voltage measuring values are in the range of the corresponding rated values.2.9.2 Binary inputs and outputsThe primary switching devices are monitored either through the auxiliary contacts or through the related sensors, which provide the status information of all the switching compartments in the switchbay. Besides that, signals coming from auxiliary components are also monitored. Consequently, at this interface the following actions are achieved:Control and interlocking of the primary switching device in the switchbayControl the CBs, disconnectors, earthing switchesSupervision of the spring status, of the continuity of CB open coil, the status of theswitching device.Providing output pulse signals for external energy counting systems .Control of the disconnectors drive motorsProviding the information regarding internal failure (watchdog.The inputs of the binary signals are isolated by an opto-coupler. In most applications, binary outputs are implemented with mechanical relays. However, in high levelapplications, like a switchboard in which motors are directly driven, static power outputs are required. A maximum of 3 binary I/O boards can be installed.3 Diagnosis and monitoringThe REF542plus monitors continuosly the condition of the system, including the switching devices. Maintenance requirements can thus be adapted to the real system condition in order to reduce down times. The following table shows the parameters monitored by the REF542plus. All the parameters can also be transmitted to a central control system where they are analyzed and processed, so that the diagnostic systems can be provided with data for reliability calculation to predict the remaining service life and maintenance actions.Type Parameters monitoredSoftware Diagnostic of REF 542 plus unitElectrical Auxiliary voltage circuitsPower supply to motor operators of the switchingdeviceContinuity of windings of the CB opening coil Mechanical components State of CB operating mechanism springsNumber of mechanical operationsGas pressure respectively densityTime Count of hours the switching device board inoperation.Contact switching time (from closed to open usingevents4 Analog outputAn optional analog output module with four configurable outputs can be inserted in the Central Unit.

★三工位开关
母线室内的三工位开关
三工位开关常用于全封闭组合电器(GIS)或复 合电器(PASS)中 所谓三工位是指三个工作位置:1隔离开关主断 口接通的合闸位置,2主断口分开的隔离位置,3接地 侧的接地位置。
2、开关柜一次设备主要额定参数
额定电压: 35KV 额定频率: 50Hz 热稳定电流(3S) :25KA
额定电流 1250A 动稳定电流(峰值):63KA
一次母线动稳定电流(峰值) :63KA 分、合闸机构和辅助回路的额定电压:DC220V
3、绝缘水平 对地、相间及普通断口工频耐压值: 隔离断口间的绝缘工频耐压值: 85KV 95KV
三工位:
工位 隔离开关 接地开关 a 分 分 b 合 分 c 分 合
三工位开关其实就是整合了隔离开关和接地开关 两者的功能,并由一把刀来完成,这样就可以实现机 械闭锁,防止主回路带电合地刀,因为一把刀只能在 一个位置,而不象传统的隔离开关,主刀是主刀,地 刀是地刀,两把刀之间就可能出误操作。而三工位隔 离开关用的是一把刀,一把刀的工作位置在某一时刻 是唯一的,不是在主闸合闸位置,就是在隔离位置或 接地位置。传统的GIS中,隔离开关和接地开关是两 个功能单元,使用电气联锁进行控制,现在最新设计 就是使用三工位隔离开关,避免了误操作的可能性。
