1. Application GUID-CF75762E-73C1-40AF-8D6F-6EC3D8395982 v3RES670 is a Phasor Measurement Unit (PMU) thatprovides power system AC voltages and currents asphasors for all voltage levels in power system networks.Phasors are provided as real and imaginary or asmagnitude and phase angle. The reference for the phaseangle is the NavStar Global Positioning System – GPSthat also supplies highly accurate time and date. Themeasured data in each PMU is time-synchronized viaGlobal Positioning System (GPS) receivers – with anaccuracy of one microsecond – and transmitted toPhasor Data Concentrators (every 100 milliseconds forexample). The accurate time tagging of measurementstaken at different geographical locations makes itpossible to derive the synchronized phasor quantities(synchrophasors). Based on synchrophasors, a numberof power system applications are available.The PMUs are installed at substation level, and can beconnected directly to current and voltage transformerswithin the substations. Each RES670 can have its ownantenna and GPS system for time synchronizationpurposes or it can receive the IRIG-B signal from anexternal GPS-based clock. It is also possible to haveboth direct GPS and IRIG-B connection to provide timesynchronization redundancy for the PMU. RES670streams out its synchrophasor data according to IEEEC37.118 and/or IEEE 1344 standards for synchrophasordata streaming and with user-selectable reporting rates.RES670 supports reporting rates of 10, 25, 50, 100, and200 frames per second for 50Hz system (or 10, 12, 15, 30,60, 120, and 240 frames per second for 60Hz system).Each RES670 can communicate its synchrophasor datato up to eight independent clients over TCP and/or sixindependent UDP channels (unicast/multicast),simultaneously. More information is available in RES670Application Manual under Wide Area MeasurementSystem section.In addition to the synchrophasor communicationstandard (IEEE 1344, IEEE C37.118), RES670 is alsocompliant to IEC 61850-8-1 standard for integration tosubstation automation systems and exchange of GOOSEmessages, when necessary. RES670 is able tocommunicate over IEC 62439-3 PRP for redundantstation bus communication for both IEEE C37.118 andIEC 61850-8-1, simultaneously.Figure 1 shows an example of a system architecture for aWide Area Monitoring System (WAMS). PMUs are thebuilding blocks for a WAMS. The architecture of a WAMSconsists of the following main components:• PMU Phasor Measurement Unit, including allaccessories for 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 UtilitiesIEC140000114-1-en.aiPhasor Data ConcentratorPDCSubstation 2 Substation 3 Substation NRouter Router Router RouterTCP/IP communication networkPMU protocol IEEE C37.118PMU PMU PMU PMUPMU PMUGPS GPS GPSGPS GPS GPSIEC140000114 V1 EN-USFigure 1. Wide Area Monitoring System architecture — overviewA Wide Area Monitoring System collects, stores,transmits and provides ways to analyze critical datafrom key points across the power networks and overlarge geographical areas. The architecture of the WAMScan provide a scalable solution, from small installationsfor data collection and basic visualization (PDC) tolarger systems with intelligent monitoring using widearea applications. The Wide Area Monitoringapplications are designed to detect abnormal systemconditions and evaluate large area disturbances in orderto preserve system integrity and maintain acceptablepower system performance.The WAMS is configured in a way to acquiresynchrophasor data from several PMUs. Based on thedata collected in the PDCs, WAMS is able to present thestate of the grid to the power system operator, and toprovide monitoring of the power system based on real-time measurements and the results of on-lineapplications. In addition, the data available from PDCsenables off-line analysis of the power system for post-disturbance assessments. It is possible to communicatethe PMU measurements and the results of the advancedapplications to SCADA/EMS systems as a way toimprove the supervision of the system, providing theoperator with a clear indication how likely the system isto collapse, thus giving the possibility to react in time.Forcing of binary inputs and outputs is a convenient wayto test wiring in substations as well as testingconfiguration logic in the IEDs.
