1. Application GUID-CF75762E-73C1-40AF-8D6F-6EC3D8395982 v4RES670 is a Phasor Measurement Unit (PMU) that providespower system AC voltages and currents as phasors for allvoltage levels in power system networks. Phasors areprovided as real and imaginary or as magnitude and phaseangle. The reference for the phase angle may be either a PTPtime synchronization source or the NavStar Global PositioningSystem - GPS, both supplying highly accurate time and date.The measured data in each PMU is time synchronized via oneof the mentioned time synchronization sources - with anaccuracy of one microsecond - and transmitted to PhasorData Concentrators (every 100 milliseconds, for example).The accurate time tagging of measurements taken at differentgeographical locations makes it possible to derive thesynchronized phasor quantities (synchrophasors). Based onsynchrophasors, a number of power system applications areavailable.The PMUs are installed at substation level, and can beconnected directly to the current and voltage transformerswithin the substations. Each RES670 may be fitted withdifferent options for time synchronization: PTP via theEthernet network, via the GPS system with an own antennafor the RES670, or via the IRIG-B signal received from anexternal GPS-based clock. It is also possible to have acombination of the three to provide time synchronizationredundancy for the PMU. RES670 streams out itssynchrophasor data according to IEEE C37.118 and/or IEEE1344 standards for synchrophasor data streaming and withuser-selectable reporting rates. RES670 supports reportingrates of 10, 25, 50, 100, and 200 frames per second for 50Hzsystem (or 10, 12, 15, 30, 60, 120, and 240 frames persecond for 60Hz system). Each RES670 can communicate itssynchrophasor data to up to eight independent clients overTCP and/or six independent UDP channels (unicast/multicast), simultaneously. More information is available inRES670 Application Manual under Wide Area MeasurementSystem. section.In addition to the synchrophasor communication standard(IEEE 1344, IEEE C37.118), RES670 is also compliant to IEC61850-8-1 standard for integration to substation automationsystems and exchange of GOOSE messages, whennecessary. RES670 is able to communicate over IEC 62439-3PRP for redundant station bus communication for both IEEEC37.118 and IEC 61850-8-1, simultaneously.Figure 1 shows an example of a system architecture for aWide Area Monitoring System (WAMS). PMUs are the buildingblocks for a WAMS. The architecture of a WAMS consists ofthe following main components:• PMU Phasor Measurement Unit, including all accessoriesfor time synchronization• TCP/IP and/or UDP/IP communication network infra-structure• PDC Phasor Data Concentrator, including wide areaapplicationsSubstation 1Visualization(Applications)Interface toSCADA / EMSData Storage and EventDriven ArchivingGateway to other UtilitiesPhasor Data ConcentratorPDCSubstation 2 Substation 3 Substation NRouter Router Router RouterTCP/IP communication networkPMU protocol IEEE C37.118PMU PMU PMU PMUPMU PMUPTP orGPS/IRIG-BIEC140000114-2-en.vsdPTP orGPS/IRIG-BPTP orGPS/IRIG-BPTP orGPS/IRIG-BPTP orGPS/IRIG-BPTP orGPS/IRIG-BIEC140000114 V2 EN-USFigure 1. Wide Area Monitoring System architecture — overviewA Wide Area Monitoring System collects, stores, transmitsand provides ways to analyze critical data from key pointsacross the power networks and over large geographicalareas. The architecture of the WAMS can provide a scalablesolution, from small installations for data collection and basicvisualization (PDC) to larger systems with intelligentmonitoring using wide area applications. The Wide AreaMonitoring applications are designed to detect abnormalsystem conditions and evaluate large area disturbances inorder to preserve system integrity and maintain acceptablepower system performance.The WAMS is configured in a way to acquire synchrophasordata from several PMUs. Based on the data collected in thePDCs, WAMS is able to present the state of the grid to thepower system operator, and to provide monitoring of thepower system based on real-time measurements and theresults of on-line applications. In addition, the data availablefrom PDCs enables off-line analysis of the power system forpost-disturbance assessments. It is possible to communicatethe PMU measurements and the results of the advancedapplications to SCADA/EMS systems as a way to improve thesupervision of the system, providing the operator with a clearindication how likely the system is to collapse, thus giving thepossibility to react in time.Forcing of binary inputs and outputs is a convenient way totest wiring in substations as well as testing configuration logicin the IEDs. Basically it means that all binary inputs andoutputs on the IED I/O modules (BOM, BIM, IOM & SOM) canbe forced to arbitrary values.1MRK 511 410-BEN BPhasor measurement unit RES670 2.2Product version: 2.2 Issued: March 2018Revision: BABB 3
