RPV architecture The RPV architecture is comprised of separate processing and measurement acquisition units, which communicate using dedicated fibre-optic links of up to 2km, allowing flexible installation and mounting. It is possible to install all the units in one panel, in a centralised solution, or it is also possible to install the acquisition units in the protection panels, communicating to one central processing unit. In the distributed architecture the electrical cabling is reduced, since it is not necessary to take all signals to one concentrated DFR panel. The RPV processing unit can be connected to either up to 8 RA331 Remote Acquisition Units, or to up to 4 RA332, or to up to 4 RA333, or a combination of them. Each RA331 can have up to 8 analogue inputs and 32 digital inputs, each RA332 can have up to 16 analogue inputs and 32 digital inputs, and each RA333 can have, in addition to the 3 default voltage high speed travelling-wave acquisition inputs, up to 8 analogue inputs and 16 digital inputs. The RPV processing unit can also accept sample data inputs of analogue signals and digital inputs from IEC61850-9-2 merging units. The RPV can be connected to a combination of inputs from RA33x acquisition units and merging units. Communications The RPV is fitted with 2 network Ethernet ports for communication to two separate networks or for redundant communications. Both copper and fibre (optional) ports are available. A third network Ethernet port for IEC61850-9- 2LE communications is available. Modbus, DNP3 and IEC 61850-8-1 protocols are implemented for integration with SCADA and DCS systems. An RS232C serial port is included for Modem communications. Signalling outputs Available are 4 dry contact relays for remote signalling one of which is used by the device self-monitoring watchdog. The other 3 outputs are user configurable. Local interface The local interface consists of 4 buttons used to navigate the LCD display to show the unit status, monitor the measurement values, identify which record files have been generated, etc. Remote interface There is an integrated web-based graphical interface for monitoring and configuration of the RPV units. The web-based interface allows the configuration of all features of the RPV311 either directly connected or via a remote Ethernet link. A standalone version of the configuration system is also available as part of the supplied RPV software tools to allow the configuration to be developed offline without the need to be connected to a physical unit. The configuration produced offline can be stored and then downloaded to multiple units using the web-based interface. The monitoring interface allows measurements being generated by the RPV311 to be viewed without any other monitoring software needing to be available. This is particularly useful during commissioning when the RPV311 will probably be the first system commissioned. The total number of input channels available in the scheme is 64 analogue inputs (current, voltage and DC transducer signals), 256 digital inputs and in addition up to 256 binary inputs related to GOOSE messages. The analogue inputs are sampled at 256 samples per cycle and have a frequency response of DC to 3 khz. The RPV is fitted with a 50GB solid state memory drive (SSD), and is time synchronised by connection to an external IRIG-B reference or using SNTP over Ethernet.

MEASUREMENT PRODUCT SOLUTIONS RPV311 Process bus applications with IEC 61850-9-2 The RPV is ready for sampled value applications according to IEC 61850-9- 2LE. The distributed architecture of the scheme, whereby the RPV central unit subscribes to data from local or remote acquisition units means that the user can specify the MU320 as the chosen acquisition unit, or can subscribe directly to other merging units or digital instrument transformers which are publishers of sampled value data streams. Interoperability is assured with Alstom s own MU320 and MU Agile merging units, the COSI range of digital instrument transformers, plus third party devices compliant to the standard. Conventional instrument transformers may be hardwired to RA33x or MU320 acquisition units, at the same time as other measurements are obtained from digital instrument transformers, allowing a mix of transformer technologies within a scheme. Such flexibility permits standardisation of the DFR solution across substations employing different primary technology generations; it prepares for future substation extensions, and allows a migration path to the full digital substation. The MU320 merging unit used to digitise the output of conventional CT and VTs has the advantage that it performs both an analogue merging unit function and binary I/O marshalling. It may be termed an integrated merging unit, making it particularly cost-effective in applications requiring bay measurements and switchgear control and monitoring in a single intelligent device. As per the RA33x, the MU320 may be deployed in a distributed scheme whereby it performs the plant interfacing in yard kiosks close to the switchgear. RA33x technology and DC applications The RA33x acquisition units use intelligent shunt measurement with optical isolation between the external world and the internal electronics. This extends Alstom s leadership in digital instrument transformer (DIT) technology, such that the measurement circuit becomes a DIT in the box. The acquisition circuit is thus transformerless, with no core to magnetise, no core to saturate, and hence negligible error. Such greater accuracy is important in high-precision measurement and phasor applications, whilst also permitting DC quantities to be measured. The analogue acquisition in the scheme produces a more accurate representation of DC and harmonic components in AC applications, also supporting full DC application too. References exist for Reason DFR solutions deployed in HVDC installations. The solution right from simple applications up to the full digital substation.

PHASOR MEASUREMENT UNIT (PMU) The RPV is able to construct accurate synchrophasor data based on the incoming measurements from the scheme s acquisition units. This makes the solution highly scalable in terms of the number of analogue channels and phasors available. The scalability from small to large substations is achieved by means of additional acquisition units to accommodate the number of feeders, which is more cost-optimised than the addition of multiple discrete PMUs. Further advantages are achieved in that the Phasor Data Concentrator (PDC) only needs to connect to a single point in the substation (the RPV, which also acts as the Substation Phasor Data Concentrator - spdc) rather than requiring a connection to multiple discrete devices. Integrating the PMU function is an ideal way to make use of the measurement accuracy, the precision time distribution, and the communication architecture already provided within our DFR scheme, negating the requirement to install a duplicate architecture solely for PMU purposes. The RPV synchrophasor measurement and publishing are carried out according to IEEE C37.118, the standard for synchrophasors in power systems. The reported values are freely selectable by the user and include voltages and currents, positive and negative sequences for voltage and current circuits, frequency, scalar quantities such as DC signals, RMS values, voltage and current imbalances and THD, and the status of any digital channel. The RPV has been tested by NIST. The RPV (PMU) is designed to monitor entire substations and power plants. In process bus architectures, the RPV acts as a smart protocol conversion from IEC 61850-9-2 to IEEE C37.118. RECORDERS The disturbance and fault (waveform) recorders are enabled by using triggers which can be generated from analogue, digital and virtual (GOOSE) inputs. The continuous recorder generates records with 16 points-per-cycle sampling rate (waveform) and 1 pointper-cycle sampling rate (magnitude, phase, RMS, frequency, positive and negative sequence, imbalance, THD, and apparent, active and reactive power). The continuous recorders are very useful tools for monitoring long term oscillations and wide area events. DFR topology example CAPTION_WHITE_lore_ipsum_(Optional)

MEASUREMENT PRODUCT SOLUTIONS RPV311 TRAVELLING WAVE FAULT LOCATION Travelling wave (TW) fault location (TWFL) is a particularly efficient way to define precisely where a fault occurred on a transmission line, to locate it to the vicinity of a particular tower, or span length of conductors. Such accuracy to within a few hundreds of metres of the actual fault point is not possible to achieve with traditional impedance-based fault location, which conversely introduces measurement errors equivalent to a few percentage points of the full line length. The MHz sampling rate of the Reason unit, and intelligent processing allow dedicated high speed algorithms to be implemented which accurately monitor the propagation of the disturbance along the monitored circuit, securing the high accuracy result The highly reliable fault location system uses an innovative and patented combination of travelling wave and fault detection algorithms. All the triggers normally associated with Digital Fault Recorders (DFRs) can also be used as an external trigger to record the travelling wave associated with the event. Travelling wave fault location: Summary view The Master station software permits users to display the fault location on a Google-earth map, onto which the GPS coordinates of substations, towers and conductors have been plotted. Maintenance crews are thus directed to the exact location of the fault, without the need to resort to vehicular, helicopter or footpatrols to find the exact location. Alstom is the leader in the field of travelling-wave fault location, as our techniques work equally-well for short-circuits and high impedance faults. The latter will typically confuse other vendor s TWFL solutions as they rely on a change of state to trigger and will be unable to declare a calculation result, or will declare an inaccurate distance. The technique does not rely on a trigger, but correlates the trip command with the continuous disturbance record data, such that a correct result will be obtained. The TWFL can be compensated for the effects of conductor sag with varying ambient temperature and load current heating effects. This trigger is generated after some preset limits are exceeded for magnitude, angle, frequency deviation, positive sequence, negative sequence, imbalance, harmonic distortion, and power. It is possible to monitor up to 4 circuits with each RPV by using the RA333 Remote Acquisition Units. Precision is not affected by line resistance, mutual coupling effects (parallel lines), load, or compensation circuits (capacitor banks). To monitor a transmission line, RPV systems are installed at each end of the line. The travelling wave records are captured in both units and are automatically transmitted to the Master station for the fault location to be calculated.

RPV Software Tools The RPV is supplied with a suite of PC software tools to manage the product and the records produced. The Scanner searches for and uploads the record files from the connected RPV units in a single or multiple substations and stores them in an organised way for later analysis. The scan for new records is run periodically at an adjustable time period. The configuration tool is a version of the web based graphical tool which can be used offline to generate the product configuration required which can then be downloaded to multiple RPV products. The TW Fault Locator is a tool that uses the records of the traveling wave front signal from the RPV units at both ends of a transmission line to locate a fault on the line. The software can output the fault location in a format which allows mapping systems such as Google Earth to display the location. RPV Manager The RPV manager software allows the management of a system of multiple RPV units installed in multiple substations. It manages the communication links and reports their status and periodically scans the network for record files not previously uploaded. The software can also receive record files automatically sent by the RPV units if enabled or as required for TW fault location. The software can also be used to backup and upload the configuration files for all RPV units in the system. Analise The powerful analise package can merge multiple waveform files from different devices, time align them, and display as a single record for side-by-side signal analysis. This greatly assists in post-fault or post-disturbance analysis, where the types of IED and the availability of timesynchronising between substations may vary. In addition, impedance based fault location and harmonic analysis calculations can be performed. The graphical analysis can be output in various picture formats and the related data can be exported in a form readable by Microsoft Excel.
