2 Product Scope

The processing unit RPV311 and the acquisition modules RA331, RA332, and RA333 offer a distributed solution for Multifunction Digital Recording. The solution is designed for the acquisition, monitoring and recording of electrical quantities normally associated with electrical power generation, transmission or distribution equipment. It is the solution for applications which require flexibility, allowing installation of RPV311 Processing Unit in existing panels and the Acquisition Modules RA331, RA332, and RA333 near to the plant seeing monitored the applications installation. The RPV311Solution is a multifunction equipment with fan-less and no rotating part design. It has an acquisition system with 16-bit A/D D converters that provide an acquisition rate of 256 points-per-cycle synchronized by the IRIG-B signal. It has a high processing capability, which allows the acquisition of up to 64 analog channels and 256 digital channels divided in up to 8 acquisition modules connected by fiber-optic links. Additionally, it is able to detect IEC 61850 GOOSE messages. It allows communication through the electrical Ethernet ports and optionally has a double internal converter for optical Ethernet interfaces. Monitoring and configuration are performed through a web interface; also, it has a human-machine interface on the front panel for displaying information. It has a MODBUS and DNP3 interface for SCADA integration. The RA331 module allows data acquisition of up to 8 analogue channels (voltage, current, or DC transducers) and up to 32 digital channels. The RA332 module allows data acquisition of up to 16 analogue channels (voltage, current, or DC transducers) and up to 32 digital channels. Both modules use 16-bit A/D converters providing an acquisition rate of 256 points-per-cycle. The RA333 module allows data acquisition of high-speed analog channels (voltage) for one transmission line. This module allows the scheme to obtain traveling wave records for fault locating. Additionally, the RA333 module allows data acquisition of up to 8 analog channels (voltage, current, or DC transducers) and up to 16 digital channels, using 16-bit A/D converters providing an acquisition rate of 256 points-per­cycle.

Page 29
Chapter 2 – Safety Information
RPV311
RPV311-TM-EN-7
29
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.
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.
Page 30
RPV311
Chapter 2 – Safety Information
30
RPV311-TM-EN-7
The functioning of the device has been certified under the circumstances described by the standards mentioned in
Chapter 17: Technical Specifications (item 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.
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 60947-1 and IEC 60947-3 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.
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:
RPV unit: 5 Amp, type T, 250V rating
RA units: 2 Amp, type T, 250V rating
CTs must NOT be fused since open circuiting them may produce lethal hazardous voltages.

3.3 Fusing Requirements

Page 31
Chapter 2 – Safety Information
RPV311
RPV311-TM-EN-7
31
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 RPV311 and RA33x 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.
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.

3.4 Equipment Connections

Page 32
RPV311
Chapter 2 – Safety Information
32
RPV311-TM-EN-7
All connections to the equipment must have a defined potential. Connections that are pre-wired, 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.
The connections: Console1, Console2, MODEM and Process bus are non-isolated and for local connection only.
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.
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.

3.5 Pre-energisation Checklist

3.6 Peripheral Circuitry

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.
Page 33
Chapter 2 – Safety Information
RPV311
RPV311-TM-EN-7
33
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 RPV311 and RA33x 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.
There might be situations in which the RPV311 and RA33x are 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.
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.

Chapter 3: Hardware Design

This chapter provides information about the hardware design of the products.

1 Hardware Architecture

The RPV311 is a multifunction processing unit and has an acquisition system with 16­bit A/D D converters that provide an acquisition rate of 256 points-per-cycle synchronized by the IRIG-B signal. It has a high processing capability, which allows the acquisition of up to 64 analog channels and 256 digital channels divided in up to 8 acquisition modules connected by fiber-optic links. Additionally, it is able to detect IEC 61850 GOOSE messages. All the registers are stored in a SSD hard disk. It allows communication through the electrical Ethernet ports and optionally has a double internal converter for optical Ethernet interfaces. Monitoring and configuration are performed through a web interface; also, it has a human-machine interface on the front panel for displaying information. It has a MODBUS and DNP3 interface for SCADA integration. The RA331 module allows data acquisition of up to 8 analog channels (voltage, current, or DC transducers) and up to 32 digital channels. The RA332 module allows data acquisition of up to 16 analog channels (voltage, current, or DC transducers) and up to 32 digital channels. Both modules use 16-bit A/D converters providing an acquisition rate of 256 points-per-cycle. The RA333 module allows data acquisition of high-speed analog channels (voltage) for one transmission line. This module allows the scheme to obtain traveling wave records for fault locating. Additionally, the RA333 module allows data acquisition of up to 8 analog channels (voltage, current, or DC transducers) and up to 32 digital channels, using 16-bit A/D converters providing an acquisition rate of 256 points-per­cycle

1.1 Processing Capability

The RPV311 has 8 link connections to communicate with RA33x acquisition units. As each acquisition unit has different number of channels and functions, they require different levels of demand from the RPV311. In order to respect the RPV311 processing capability the number of RA33x that can be connected to the RPV311 obey the following rule: The RPV311 can process 12 logical slots and each RA demands the following number of slots.
The user can combine the RA units as long as the logical sum of the slots value of each RA do not exceed the maximum number of 12.
Note:
Differently from the RA331/332 the RA333 has two link: One for the DFR functionality and another for the TW functionality.

2.2 Synchronization

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 of the IRIG-B signal.
2.2.1 Time Source
On the screen TIME SOURCE it is possible to configure how the RPV311 will interpret the time zone of the IRIGB signal and also the IP address of the NTPv2, 3 or 4 server. The configurable settings are:
A The TIMEZONE defines if time zone information is supplied by the IEEE1344 extensions of the IRIG-B signal, or if it is manually set. This option will allow the
Page 49
RPV311

RPV311 to identify the UTC time using information from the signal or from the manual configuration of the user:
The time setting that the RPV will use for time stamping is configured on the screen Internal Clock.
It is possible to configure 30 min time zones.
B The NTP FALLBACK SERVER defines the IP address of the SNTP time server to be used to provide time synchronism when the IRIG-B is not connected.
2.2.2 Internal Clock
On the screen the internal clock for time stamping the registers and logs is configured, as well as day light saving configurations.The configurable settings are:
When Auto (IRIGB with extensions) is selected the RPV311 shall use the
information of time zone sent within the IRIGB signal to recover the UTC time.
When Manual is selected the RPV will not consider eventual time zones
within the IRIGB signal, and rather it will use the UTC time zone configured in the Manual parameter to retrieve the UTC time. This option is used specially when the IRIGB does not inform the time zone, so the RPV311 cannot retrieve the UTC time unless we inform the time zone manually.
A The TIMEZONE defines if time zone information is supplied by the IEEE1344 extensions of the IRIG-B signal, or if it is manually set.
When Auto is selected the RPV311 will use the same local time sent within

2.4 Acquisition with remote acquisition modules

The RPV311 data acquisition can be performed by the RA331, RA332 and RA333 remote acquisition modules. The RA333 module consists of two different acquisition systems. One, called DFR, is used for analog data acquisition of 50/60 Hz of voltage, current, or DC. The other, called TW, is used for high-speed acquisition of traveling waves. The RA333 (TW) and RA333 (DFR) are physically installed in the same module, but are logically independent, i.e., the RPV311 will be treated as two logical modules. The RA331, RA332 and RA333 (DFR) modules are independent and use 16-bit opto­isolated A/D converters with simultaneous acquisition of all channels provided by the IRIG-B signal, thus ensuring that the frequency acquisition is kept constant. The analog channels for current measurement use internal shunts to minimize the effects of phase variation caused by transformers. There is a delay in the data transmission of the acquisition module for the processing module proportional to the length of the fiber-optic cable. This delay is compensated by the RPV311 considering the information of the fiber length specified in the configuration of the equipment. The links should be installed of positions A to L. Intermediate empty positions are considered as "using" 8 analog channels. Each link must be configured considering the module type and its inputs. To configure the links, access the LINKS section, shown in Figure 12.
Figure 12: Links between RPV and acquisition modules configuration section
Page 53
RPV311
Chapter 4 – Configuration
RPV311-TM-EN-7
53
A The Position represents the position where the acquisition module is physically connected to the RPV311. Positions A to L.
B The Module scroll box allows user to select the acquisition module used in the link and its characteristics based on the Part Number of the module. The modules can be:
RA331: Acquisition module with up to 8 analog (voltage, current, or DC) and 32 digital channels;
RA332: Acquisition module with up to 16 analog (voltage, current, or DC) and 32 digital channels;
RA333 (TW): High frequency acquisition module with 3 high-speed analog channels for acquisition of the traveling waves;
RA333 (DFR): Acquisition module with up to 8 analog (voltage, current, or DC) and 16 digital channels.
C The Fiber length text field allows user to enter the fiber length, in meters, to compensate the delay in the data transmission between the acquisition and processing modules.
All analog channels have two configuration options. Circuits and channels will be configured based on the option selected. In the Inputs section, shown in Figure 13, it is possible to configure the analog inputs of the acquisition module connected with the RPV311 configured in the previous section. It is important to configure the analog inputs for voltage or current, according to the physical configuration of the module, shown in Chapter 15: Installation. The RA333's high-speed acquisition channels do not require configuration, since they are dedicated for voltage measurement. To improve the accuracy of the measurement, a correction factor can be manually provided. Inputs without the correction factor have accuracy better than 1%. The digital channels do not have type selection.

A The POSITION indicates the position of each analog input on the back panel of the module.
B The INPUT scroll box allows user to select the type of the signal to be measured (AC voltage 115 V, AC current 1 A, AC current 5 A, DC current 0-20 mA or DC voltage ±10 V).
C The ADJUSTMENT text field allows user to enter a correction factor to adjust the accuracy of the measurement.

2.5 Acquisition with Sampled Values

The RPV311 data acquisition can be performed by Sampled Values data, incoming of Merging Units. The acquisition is done by connecting the Process Bus Ethernet port to the Sampled Values generator. If the acquisition is done by Sampled Values, there is no physical link to configure. The configuration is performed by Subscription links. Each subscription link contains data of 4 current (Phases A, B, C and Neutral) and 4 voltage (Phases A, B, C and Neutral) circuits. Once a subscription link is created, the RPV311 automatically configures the first channels as current and the last as voltage, as shown in Figure 86. This is done because the Merging Units send the Sampled Values package according to the IEC 61850-9-2LE. The RPV311 processing module can be configured with up to 8 Subscription links.

A Selecting the AUTO ERASE check box, erases older record automatically if memory
capacity exceeds 90%.
B The ERASE ALL scroll box allows user to choose a type of record (fault, disturbance, steady-state and SOE) to be removed.
C The <EXECUTE> button allows user to erase all the records on the list.
For details about the memory capacity of each record type, see Chapter 6: Records.
It is possible to send a record to two different servers. In the configuration interface it is possible to configure the IP address of each destination server and the type of record which will be sent. When a new record is generated and the record type is enabled for auto upload, it is automatically transmitted to the servers. If at the upload time the server is not available or the network is unreadable, the record is not retransmitted. In this case, the record will be transmitted only through the automatic scanning by the server. The automatic upload of records is a process in which the records are transferred to the server in advance. To ensure that all the records are stored in the server, it is necessary that the server perform the scanning process periodically. The records that have already been transmitted to the server are not retransmitted. In the section shown in Figure 20, it is possible to automatically upload records to a preset destination.

17 PMU

17.1 General

17.2 Data

Synchrophasors are measured and broadcast according to the specifications contained in IEEE C37.118, Standard for Synchrophasors for Power Systems. For further information about the PMU, see Chapter 8: PMU. The RPV311 is able to send up to 4 PMU in the frame of data and the configuration is divided into three sub menus: General, Data and Communication described below.
This window is responsible for configuring the following settings:
<Enable> Turns the PMU streaming on and off. The <ID> text field allows user to enter a single ID for the entire PMU streaming; the range is of 1 to 65534. The <Rate> scroll box allows user to select a frame transmission rate; at 60Hz the parameters are10, 12, 15, 20, 30, and 60 fps; at 50Hz they are 10, 25 and 50Hz.
The data selection is related to the groups configuration (refer to Chapter 4: Configuration, Section 15 - Groups). Each group can configure a PMU with its specific data and frequency. The parameters present on the screen are: <GROUP> this setting displays all the values related to the selected group that can be transmitted. Each group has a particular setting for the frequency and rate of change of frequency related to it. The <ENABLE> check box allows user to enable data packet transmission. The <ID> text field allows user to enter a single PMU transmitter ID; the range is of 1 to 65534. <FREQUENCY> selects the reference frequency of PMU. It is possible to choose which signal is used to calculate the frequency, namely: Voltage from phases A, B or C, voltage positive sequence, current from phases A, B or C. The <PHASORS>, Analog data and Digital data fields contain all the inputs configured on the equipment. The check box allows user to select the input to evaluate magnitudes. The <DESELECT ALL> button allows user to deselect all the magnitudes selected.

17.3 Communication

The RPV311 has two types of operation modes: Commanded; and Spontaneous. When using the Commanded mode the RPV only transmits data when the client requests. This mode allows up to 4 destinations of the PMU frame through the UDP ports. The ports the RPV311 uses to send synchrophasors are:

In Spontaneous mode the RPV sends the PMU data automatically up to 4 different socket addresses (IP + port number). All 4 destination configuration can be set as unicast or multicast transmission. The parameters of the Communication screen are listed below: <COMMANDED> Sets the respective streams of data to Commanded mode. When set to Commanded mode. The RPV311 can send the HDR, CFG2 and CFG3 frames according to the client’s IED request. <SPONTANEOUS> Sets the respective streams of data to Spontaneous mode. When in Spontaneous mode it is also possible to select which CFG frame the PMU will use. The options are CFG2 and CFG3, at least one of them must be set. Additionally, it is possible to choose if the HDR frame will be sent. <UNICAST> Sets the addressing of the respective streams of data to Unicast mode. This kind of transmission connects to a single IP address and the routing of the messages though the available Ethernet ports are managed by the RPV system. It is important that the destination IP and the RPV311 share the same subnetwork address. <MULTICAST> Sets the addressing of the respective streams of data to Multicast mode. This mode required the user to choose which Ethernet interface the RPV shall use to convey the data.

18 MODBUS

Status, analog and digital data are available in MODBUS registers. Access to SCADA integration is provided over the Ethernet interface. Up to 8 simultaneous connections are allowed a maximum rate of 60 accesses per second. For further information about MODBUS, see Chapter 9: MODBUS. Each register reports 16-bit data. Registers are divided into 3 groups:

Note: Whenever MODBUS/DNP3 feature is enabled, the RPV will send both types of messages. It is not possible to enable just one protocol.
The DNP3 functionality is fully associated with the MODBUS functionality in the RPV311. To use the DNP3 protocol, it is necessary to insert a configuration key at the equipment to unlock the MODBUS and DNP3 functionalities. However, it is necessary to check the HABILITATED option at the web interface and insert analog channels block or digital channel blocks at MODBUS/DNP3 menu.

RPV311 restarting proccess, the DNP3 library reads the configuration archive and adds digital channels sequentially, associating to an integer number plus an increment, starting at zero, for each digital channel. GOOSE digital channels are not added to the DNP3 database.

19.2 DNP3 configuration example

19.2.1 Adding digital channels
First step for digital channel DNP3 database association is to create a digital channel.
Figure 43 shows the digital channels configured and table below shows associated
number at the DNP3 database for each digital channel of the example.

Note:
For analog channels, the first number associated at the DNP3 database is 5. Numbers 1, 2, 3 and 4 are reserved for equipment information.
19.2.2 Adding analog channels
The analog data possibilites for the DNP3 communication procol are the same as for MODBUS. The MODBUS analog data are shown in section 1.3. To configure the analog data, access the MODBUS/DNP3 menu via web interface. Analog data are added in a sequential way, like the digital channels, but the starting number for the analog channels is 5. Numbers 0, 1, 2, 3 and 4 are reserved for equipment information.
Figure 44 shows the analog channels selected at the MODBUS/DNP3 menu and the
table below it shows the associated number at the DNP3 database for each example analog channel.
