MU320-TM-EN-4 25

26 MU320 Chapter 2 Safety Information 4 INSTALLATION, COMMISSIONING AND SERVICING 4.1 LIFTING HAZARDS Many injuries are caused by: Lifting heavy objects Lifting things incorrectly Pushing or pulling heavy objects Using the same muscles repetitively Plan carefully, identify any possible hazards and determine how best to move the product. Look at other ways of moving the load to avoid manual handling. Use the correct lifting techniques and Personal Protective Equipment (PPE) to reduce the risk of injury. 4.2 ELECTRICAL HAZARDS All personnel involved in installing, commissioning, or servicing this equipment must be familiar with the correct working procedures. Consult the equipment documentation before installing, commissioning, or servicing the equipment. Always use the equipment as specified. Failure to do so will jeopardise the protection provided by the equipment. Removal of equipment panels or covers may expose hazardous live parts. Do not touch until the electrical power is removed. Take care when there is unlocked access to the rear of the equipment. Isolate the equipment before working on the terminal strips. Use a suitable protective barrier for areas with restricted space, where there is a risk of electric shock due to exposed terminals. Disconnect power before disassembling. Disassembly of the equipment may expose sensitive electronic circuitry. Take suitable precautions against electrostatic voltage discharge (ESD) to avoid damage to the equipment. NEVER look into optical fibres or optical output connections. Always use optical power meters to determine operation or signal level. 26 MU320-TM-EN-4

27 Chapter 2 Safety Information MU320 Testing may leave capacitors charged to dangerous voltage levels. Discharge capacitors by reducing test voltages to zero before disconnecting test leads. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Operate the equipment within the specified electrical and environmental limits. Before cleaning the equipment, ensure that no connections are energised. Use a lint free cloth dampened with clean water. Integration of the equipment into systems shall not interfere with its normal functioning. The functioning of the device has been certified under the circumstances described by the standards mentioned in Chapter 9 (Type Tests). Usage of the equipment in different conditions from the specified in this manual might affect negatively its normal integrity. The equipment shall have all their rear connectors attached even if they are not being used, in order to keep their levels of ingress protection as high as possible Never manipulate liquid containers near the equipment even when it is powered off. Avoid modification to the wiring of panel when the system is running. VT circuits must never be left short circuited. 4.3 FUSING REQUIREMENTS A high rupture capacity (HRC) fuse type with a maximum current rating of 10 Amps and a minimum dc rating of 250 V dc may be used for the auxiliary supply (for example Red Spot type NIT or TIA). Alternatively a miniature circuit breaker (MCB) of type C, 10A rating, compliant with IEC may be used. Digital input circuits should be protected by a high rupture capacity NIT or TIA fuse with maximum rating of 10 A, or equivalent MCB as above. For safety reasons, current transformer circuits must never be fused. Other circuits should be appropriately fused to protect the wire used. MU320-TM-EN-4 27

28 MU320 Chapter 2 Safety Information Reason devices contain an internal fuse for the power supply which is only accessed by opening the product. This does not remove the requirement for external fusing or use of an MCB as previously mentioned. The ratings of the internal fuses are: MU320 unit: 2 Amp, type T, 250V rating CTs must NOT be fused since open circuiting them may produce lethal hazardous voltages. 4.4 EQUIPMENT CONNECTIONS Terminals exposed during installation, commissioning and maintenance may present a hazardous voltage unless the equipment is electrically isolated. Tighten M3 clamping screws of heavy duty terminal block connectors to a nominal torque of 1.0 Nm. Tighten captive screws of header-type (Euro) terminal blocks to 0.5 Nm minimum and 0.6 Nm maximum. Always use insulated crimp terminations for voltage and current connections. Always use the correct crimp terminal and tool according to the wire size. In order to maintain the equipment s requirements for protection against electric shock, other devices connected to the MU320 shall have protective class equal or superior to Class I. Watchdog (self-monitoring) contacts are provided to indicate the health of the device on some products. We strongly recommend that you hard wire these contacts into the substation's automation system, for alarm purposes. Earth the equipment with the supplied PCT (Protective Conductor Terminal). Do not remove the PCT. The PCT is sometimes used to terminate cable screens. Always check the PCT s integrity after adding or removing such earth connections. The user is responsible for ensuring the integrity of any protective conductor connections before carrying out any other actions. 28 MU320-TM-EN-4

29 Chapter 2 Safety Information MU320 The PCT connection must have low-inductance and be as short as possible. For best EMC performance, ground the unit using a 10 mm (0.4 inch) wide braided grounding strap. All connections to the equipment must have a defined potential. Connections that are prewired, but not used, should be earthed, or connected to a common grouped potential. Pay extra attention to diagrams before wiring the equipment. Always be sure that the connections are correct before energizing the circuits. 4.5 PRE-ENERGISATION CHECKLIST Check voltage rating/polarity (rating label/equipment documentation). Check CT circuit rating (rating label) and integrity of connections. Check protective fuse or miniature circuit breaker (MCB) rating. Check integrity of the PCT connection. Check voltage and current rating of external wiring, ensuring it is appropriate for the application. 4.6 PERIPHERAL CIRCUITRY Do not open the secondary circuit of a live CT since the high voltage produced may be lethal to personnel and could damage insulation. Short the secondary of the line CT before opening any connections to it. Reason devices DO NOT feature any automatic CT shorting feature. Therefore external shorting of the CTs is mandatory. Check the equipment documentation and wiring diagrams carefully. Where external components such as resistors or voltage dependent resistors (VDRs) are used, these may present a risk of electric shock or burns if touched. Operation of computers and equipment connected to MU320 under environmental conditions such as temperature and humidity that exceed the conditions specified in their respective manuals can cause malfunctioning or even irreversible damage to them or the nearby installation. MU320-TM-EN-4 29

30 MU320 Chapter 2 Safety Information There might be situations in which the MU320 is operating within its environmental operational range, but the computers, equipment connected to them or nearby equipment are operating outside their operational range. That situation can cause malfunctioning and/or irreversible damage to those devices. In that occasion the communication to the Reason equipment might be compromised but its recording, operational and safety capacities will not be affected. Take extreme care when using external test blocks and test plugs such as the MMLG, MMLB and P990, as hazardous voltages may be exposed. Ensure that CT shorting links are in place before removing test plugs, to avoid potentially lethal voltages. 4.7 UPGRADING/SERVICING Do not insert or withdraw modules, PCBs or expansion boards from the equipment while energized, as this may result in damage to the equipment. Hazardous live voltages would also be exposed, endangering personnel. Internal modules and assemblies can be heavy and may have sharp edges. Take care when inserting or removing modules into or out of the IED. 30 MU320-TM-EN-4

31 Chapter 2 Safety Information MU320 5 DECOMMISSIONING AND DISPOSAL Before decommissioning, completely isolate the equipment power supplies (both poles of any dc supply). The auxiliary supply input may have capacitors in parallel, which may still be charged. To avoid electric shock, discharge the capacitors using the external terminals before decommissioning. Avoid incineration or disposal to water courses. Dispose of the equipment in a safe, responsible and environmentally friendly manner, and if applicable, in accordance with country-specific regulations. MU320-TM-EN-4 31

35 Chapter 3 Hardware Design MU320 2 HARDWARE ARCHITECTURE All MU320 control and implementation are performed in a single FPGA (Field Programmable Gate Array) component, not using conventional microprocessors or microcontrollers. The acquisition and digital filtering control are implemented by hardware, allowing a reduced runtime without affecting performance, provided by the parallelism of the solution. Figure 6 shows a block diagram of the overall equipment. Note the simplicity of the system provided by the use of an FPGA responsible for all the processing and control. Figure 6: Simple Block Diagram of MU320 Analog signals (voltages and currents) are initially conditioned, lowering input levels to appropriate values for A/D converters. Each channel has an A/D converter implemented independently with delta-sigma modulators. Analog current channels (IA, IB, IC, and IN) are isolated from each other and from the rest of the system. Analog phase voltages (VA, VB, and VC) are isolated from the rest of the system but not from each other. Analog channel voltage VX is isolated from voltage phase channels and from the rest of the system. The operating frequency of the system is calculated from the zero crossing of voltage and current analog sampling. It is independently calculated for each analog channel. Digital input signals are conditioned and then isolated by optocouplers, going through the FPGA which transmits the information via GOOSE messages to the Ethernet interface. Digital inputs can be used from the MU320 to acquire information from the system, for example, the state of circuit breakers and switches, and transmit to IEDs through GOOSE messages. The digital outputs are triggered by GOOSE inputs associated through application software. The digital outputs are associated with GOOSE messages from other IEDs, for example, to send commands to switching units (circuit breaker, recloser, etc.) and announcements for remote signaling of events and status.

The IP address and gateway address of each port have to be within the same subnet range to the software can validate the configuration. Also the Ethernet 1 and 2 IP addresses cannot be within the same subnet range SYNCHRONIZATION The MU320 supports time synchronization with PTP, demodulated IRIGB and you can also configured the option Without sync to disable the time sync. It is possible to configure the MU320 to use the same time zone as the source synchronization signal or to configure the time zone locally. The MU320 also allows the configuration of the daylight saving time. Thise configuration are used to time stamp the log file TIME SOURCE This screen configures the which signal will be used to time sync: IRIGB or PTP. The IRIGB option does not have parameters to configure the PTP option has the following parameters: The Profile field allows choosing the group of functionalities assigned to the PTP application. The MU320 provides three options: The POWER profile has all its parameters pre-set and they cannot be altered. The parameters are the follow: Domain number 0; Network Protocol: Ethernet Level 2; Operation Mode: One step; Delay Mechanism: Peer-to-peer; Grandmaster Priority: #1 255; #2 255; Annouce Receipt Timeout: 3 The CUSTOM profile has all its parameters opened for user configuration. The P2P Default profile is partially configurable. The pre-set values are: Domain number: 0; Grandmaster Priority: #1 128; #2 128 Configurable parameters are: Domain number: A PTP domain is a collection of one or more PTP subdomains. A subdomain is a logical grouping of 1588 clocks that synchronize to each other using the PTP protocol, but that are not necessarily synchronized to PTP clocks in another PTP subdomain. Subdomains provide a way of implementing disjoint sets of clocks, sharing a common network, but maintaining independent synchronization within each set. The domain number can be set as 0, 1, 2 or 3. Network protocol: allows the user to choose between the UDP protocol and Ethernet layer 2. Operation mode: Two options are available: Two-step: In two-step-mode the master sends a synchronization message SYNC message with an estimated value of the time cyclically to the connected slaves. Parallel to this, the time at which the message MU320-TM-EN-4 63

64 MU320 Chapter 4 Configuration leaves the sender is measured as precisely as possible. The master then sends this actual exact transmission time of the corresponding sync message to the slaves in a second message - follow-up message. These also measure the reception time of these messages as exactly as possible and can correct the correction value (offset) to the master from it. The slave clock is then corrected by this offset. If the transmission line were to have no delay, both clocks would be synchronized. One-step: The master sends a synchronization message SYNC message with the precise value of the time cyclically to the connected slave. Other than in two-step-mode, the precise time is inserted into the SYNC message on-the-fly by the hardware. No FOLLOWUP messages are needed in this mode. The calculation of the offset is the same as in two-step-mode.. Delay Mechanism: End-to-end: Only measure the time taken for a PTP event message to transit the bridge and provide this information to the receiving clocks in the correction field of the PTP message. In this mode the propagation delay of the link connected to the port is not corrected Peer-to-peer: Use the peer delay mechanism for the delay measurement. In addition to providing PTP event transit time information the, also provides corrections for the propagation delay of the link connected to the port receiving the PTP event message The peer delay mechanism measures the port to port propagation delay time between two directly connected ports sharing the same communication technology. The GRANDMASTER PRIORITY: Is an administratively assigned precedence hint used by the Best Master Clock algorithm (BMC) to help select a grandmaster for the PTP domain. The range is from 0 to 255. Announce Receipt Timeout: configures the interval between PTP announce messages on an interface or the number of PTP intervals before a timeout occurs on an interface LOCAL TIME SETTINGS Allows the configuration of the time zone. It can be set as the same of the source time signal or it can be adjusted locally. Also allows configuring the daylight saving time. If the IRIG-B signal has the CF extensions (IEEE1344), timing information as date, hour, year, time zone and daylight saving time can be provided by the signal. Time zone and daylight saving time information can also be manually set via the Web Interface, overriding the information from the IRIG-B signal. In the Time Source section, shown in Figure 36, it is possible to insert the source timing parameters, such as a satellite synchronized clock. 64 MU320-TM-EN-4

The Scale Factor is always set to and the Offset to The values transmitted in the SV packet are integers and the Scale Factor and the Offset are used to translate the sent values to the actual system values using the following formula: System primary value = i x scale factor + offset i = integer representation of the measured value E Instantaneous Voltage Values L2. The Scale Factor is always set to and the Offset to The values transmitted in the SV packet are integers and the Scale Factor and the Offset are used to translate the sent values to the actual system values using the following formula: System primary value = i x scale factor + offset Where: i = integer representation of the measured value F <Cancel>: this button cancels the time source edition and goes back to the main screen of the Merging Unit Configurator. G <Ok>: this button confirms the time source edition. Accordint to IEC : The reason for integer representation is so that IEDs without FLOATING POINT capabilities are enabled to support analogue values. In this case, the scalefactor and offset may be exchanged offline between clients and servers. The reason for both integer and floating point representation is so that IEDs without FLOATING POINT capabilities are enabled to support analogue values. In this case, the scalefactor and offset may be exchanged offline between clients and servers. 6.3 GOOSE SETTINGS MU320 may transmit and receive GOOSE messages, according to IEC standard.

79 Chapter 5 - Operation MU320 OPERATION CHAPTER 5

80 Chapter 5 - Operation MU320 1 CHAPTER OVERVIEW The MU320 has an application software called Merging Unit Configurator, that downloads equipment Log files, and a local interface with important status indicators. Log file is used to verify the equipment system events. This chapter describes the local and remote interfaces of the equipment. For information about software installation, refer to Chapter 7. THIS CHAPTER CONTAINS THE FOLLOWING SECTIONS: Local Interface 81

81 Chapter 5 - Operation MU320 2 LOCAL INTERFACE MU320 local interface is comprised of six status indicators, as shown in Figure 47. A Equipment status indicators: Figure 47: MU320 local interface MU320-TM-EN-4 81

82 MU320 Chapter 5 - Operation The ALARM indicator should light up for a brief period of time while the unit is being initialized. After concluding the initialization, the unit will start operating and this indicator should turn off. In case the ALARM indicator remains on, the unit will not be in operation and operator assistance will be necessary. The IN SERVICE indicator lights up when the equipment is operating normally and has already been configured. When the IN SERVICE indicator lights up on the front panel, the signaling contact IN SERVICE on the rear panel of the equipment will be open. The LINK 1 and LINK 2 indicators lights up when the Ethernet 1 and Ethernet 2 ports are properly connected to the network and are active, respectively. The SYNC indicator lights up when the equipment is synchronized with time source that has reference from GPS satellites. This indicator blinks when the equipment is synchronized with time source that has missed the reference from GPS satellites. The POWER indicator lights up when the power supply is connected to the equipment. Note: The equipment will not come into operation mode, and will not lights up IN SERVICE indicator, before the first configuration 82 MU320-TM-EN-4

83 Chapter 5 - Operation MU320 3 MEASUREMENT BEHAVIOR When the analogue values measured by the MU320 exceeds the dynamic range, i.e. when the readings are greater than 20 x I n, the MU320 will assert a quality bit within the SV frame known as outofrange, described in the IEC ed.2 standard. The purpose of this bit is to flag to the IEDs in the Process Bus that the data sent by the MU320 does not represent the actual physical quantity, since the analogue signal exceeded the dynamic range of the device and, thus, the measurement is out of range. During the period of time that the MU320 is out of range, the value sent by the device will be the maximum value of the dynamic range (20 x I n ). The figures below exemplify it. The top figure is the actual signal and the bottom figure is the measure sent with the outofrange bit asserted. Figure 48: Values when MU320 is with outofrange bit asserted MU320-TM-EN-4 83

84 MU320 Chapter 5 - Operation 4 HOLDOVER, FREE RUNNING AND RESYNCHRONIZATION In case of sync signal loss the MU320 enters the holdover state which lasts 30 seconds, during this time the MU320 will retain the sync status as locked. After that the MU320 enters the free running and will alarm sync not locked status. When the sync signal is recovered the MU320 runs a process of resynchronization that depends on the duration of the time sync loss. There are two kind of resynchronization. The first one is for time sync loss is 5 ms the MU320 will adjust the internal sync gradually until the internal PPS reaches the locked zone. If the time sync loss is > 5 ms the resynchronization will be performed by a phase shift to the new reference. All these processes are described by the IEC MU320-TM-EN-4

85 Chapter 5 - Operation MU320 5 TEST MODE The test mode is configure in the IED tab in the Merging Unit configuration software. It allows configuring the SV and GOOSE test mode. There are four options available on this screen: a) SV MU01 Enabled: Activate the test bit in the SV packet of the MU01 logical device and sets the quality DataAttribute to test. b) SV MU02 Enabled: Activate the test bit in the SV packet of the MU02 logical device and sets the quality DataAttribute to test. c) GOOSE Enabled: Sets the quality DataAttribute to test. d) Receive Simulated GOOSE Enabled: When this mode is enabled the MU will take the messages with the test bit on into account and neglect the messages with the test bit off.

THIS CHAPTER CONTAINS THE FOLLOWING SECTIONS: Handling the Goods 93 Normal Use of the Equipment 94 Mounting the Device 95 Cables and Connectors 96 Case Dimensions 107 Merging Unit Configurator Software Installation 110 MU320-TM-EN-4 92

93 Chapter 7 Installation MU320 2 HANDLING THE GOODS Our products are of robust construction but require careful treatment before installation on site. This section discusses the requirements for receiving and unpacking the goods, as well as associated considerations regarding product care and personal safety. Before lifting or moving the equipment you should be familiar with the Safety Information chapter of this manual. 6.4 RECEIPT OF THE GOODS On receipt, ensure the correct product has been delivered. Unpack the product immediately to ensure there has been no external damage in transit. If the product has been damaged, make a claim to the transport contractor and notify us promptly. For products not intended for immediate installation, repack them in their original delivery packaging. 6.5 UNPACKING THE GOODS When unpacking and installing the product, take care not to damage any of the parts and make sure that additional components are not accidentally left in the packing or lost. Do not discard any CDROMs or technical documentation. These should accompany the unit to its destination substation and put in a dedicated place. The site should be well lit to aid inspection, clean, dry and reasonably free from dust and excessive vibration. This particularly applies where installation is being carried out at the same time as construction work. 6.6 STORING THE GOODS If the unit is not installed immediately, store it in a place free from dust and moisture in its original packaging. Keep any de-humidifier bags included in the packing. The de-humidifier crystals lose their efficiency if the bag is exposed to ambient conditions. Restore the crystals before replacing it in the carton. Ideally regeneration should be carried out in a ventilating, circulating oven at about 115 C. Bags should be placed on flat racks and spaced to allow circulation around them. The time taken for regeneration will depend on the size of the bag. If a ventilating, circulating oven is not available, when using an ordinary oven, open the door on a regular basis to let out the steam given off by the regenerating silica gel. On subsequent unpacking, make sure that any dust on the carton does not fall inside. Avoid storing in locations of high humidity. In locations of high humidity the packaging may become impregnated with moisture and the de-humidifier crystals will lose their efficiency. The device can be stored between 25º to +70ºC for unlimited periods or between -40 C to + 85 C for up to 96 hours (see technical specifications). 6.7 DISMANTLING THE GOODS If you need to dismantle the device, always observe standard ESD (Electrostatic Discharge) precautions. The minimum precautions to be followed are as follows: Use an antistatic wrist band earthed to a suitable earthing point. Avoid touching the electronic components and PCBs. MU320-TM-EN-4 93

137 APPENDIX A - PRP

138 Appendix A - PRP MU320 1 PARALLEL REDUNDANCY PROTOCOL (PRP) The basis of this method is to achieve redundancy is to have two independent paths between two IEDs. The principal advantage of PRP is its interruption-free switchovers, which take no time at all to switch over in failure situations and thus offer the highest possible availability, provided both networks do not fail simultaneously The sender IED uses two independent network interfaces that transmit the same data at the same time. The redundancy monitoring protocol then makes sure that the recipient uses only the first data packet and discards the other one. If only one packet is received, then the recipient IEDs knows that a failure has occurred on the other path. This principle is employed by the parallel redundancy protocol (PRP), which is described in the IEC standard. PRP uses two independent networks with any topology and is not limited to ring networks. PRP is implemented in the end devices, while the switches in the networks are standard switches with no knowledge of PRP. An end-device with PRP functionality is called a double attached node for PRP (DAN) and has a connection to each of the two independent networks. A standard device with a single network interface (single attached node, SAN) can be connected directly to one of the two networks. Naturally, in this case, the device will have no redundant path available in the event of a failure. A SAN can alternatively be connected to a redundancy box (RedBox) that connects one or more SANs to both networks. SANs do not need to know anything about PRP, they can be standard devices. In many applications only critical equipment will need a dual network interface and less vital devices can be connected as SANs, with or without a redundancy box.
