Kev daws teeb meem rau Smart Grid & Utilities
Cov phiajcim hluav taws xob niaj hnub xav tau lub sijhawm sib koom ua ke hla kev tiv thaiv relays, phasor ntsuas ntsuas (PMUs), cov ntaub ntawv kaw tseg, thiab SCADA systems. IEEE C37.118 thiab IEC 61850 tus qauv tswj hwm sub-microsecond lub sijhawm raug rau PMU cov ntaub ntawv sib sau ua ke thiab kev tshuaj xyuas txhaum. Cov Txheej Txheem Hauv Cheeb Tsam Dav Hlau (WAMS) yog nyob ntawm cov sijhawm teem sijhawm los txheeb xyuas cov xwm txheej hauv thaj chaw sib cais, ua rau cov neeg ua haujlwm tshawb xyuas qhov tsis ruaj khov thiab tiv thaiv kev ua tsis tiav.
Smart grid sij hawm yuav tsum tau ua kom muaj zog rau GPS jamming thiab spoofing tawm tsam, uas tau dhau los ua kev hem thawj rau cov txheej txheem tseem ceeb. Lub sijhawm ua haujlwm ruaj khov muab ntau qhov chaw siv, kev faib tawm tsis tu ncua, thiab txuas ntxiv muaj peev xwm tuav tswj kev ua haujlwm thaum lub sijhawm GNSS tawg.
Cov Kev Xav Tau
Lub sijhawm ntse daim phiaj xwm txheej yuav tsum muab:
• UTC- lub sijhawm taug qab tau zoo dua 1 microsecond qhov tseeb ntawm txhua qhov chaw nres tsheb
• IEEE 1588v2 (PTP) Grandmaster muaj peev xwm rau IEC 61850 substations
• IRIG-B thiab 1PPS cov khoom tso tawm rau kev tiv thaiv qub txeeg qub teg thiab PMUs
• 10MHz siv rau cov khoom siv saib xyuas zaus
• Tsis siv neeg lub sij hawm qhov chaw nrog tsis siv neeg poob
• Ntxiv kev tuav pov hwm (teev mus rau ib hnub) thaum lub sij hawm GNSS outs
• Kev saib xyuas hauv nruab nrab thiab kev tswj hwm ntawm txhua lub sijhawm khoom muaj nqis
Cov khoom pom zoo
GS5500 NTP / PTP Lub Sijhawm Server
Lub GS5500 ua haujlwm ua tus thawj PTP Grandmaster rau substation LAN, faib IEEE 1588v2 lub sijhawm rau IEDs, Kev Sib Koom Tes, thiab PMU cov khoom siv hla lub substation Ethernet network. Nws kuj muab NTP rau SCADA systems thiab tswj chaw ua haujlwm.
GS5620B Rubidium Sijhawm Server
Nrog rubidium tuav tau zoo dua 1 microsecond raug tshaj 24 teev, GS5620B ua kom lub sijhawm txuas ntxiv thaum txuas ntxiv GNSS tawm los ntawm jamming, spoofing, lossis kav hlau txais xov puas.
GS3100 GPS NTP Sijhawm Server
Rau cov chaw faib khoom sib txuas uas yuav tsum tau them nqi -NTP lub sij hawm zoo, GS3100 muab GPS txhim khu kev qha- synchronized NTP nrog tus nqi zoo heev rau kev xa tawm loj -.
GS5600 Lub Sijhawm Synchronization Server
GS5600 muab kev tswj xyuas lub sijhawm nruab nrab rau cov khoom siv hluav taws xob loj, sib sau lub sijhawm sijhawm los ntawm ntau lub chaw nres tsheb thiab muab kev sib koom ua ke saib xyuas, tswj lub tswb, thiab tshaj tawm.
GS5210 Grandmaster Clock
Rau substations nrog cov cuab yeej qub txeeg qub teg xav tau 10MHz, 1PPS, thiab IRIG-B, GS5210 tsim txhua qhov kev siv cov cim qhia los ntawm ib qho GNSS- kev qhuab qhia platform.
GS5710 Fiber Optic Transmission Equipment
GS5710 tso cai rau ntev - ncua sij hawm hloov mus los ntawm cheeb tsam tswj chaw mus rau tej thaj chaw deb substations tshaj fiber ntau infrastructure, tshem tawm qhov xav tau rau ib tug neeg GPS receivers ntawm txhua qhov chaw.
System Architecture
Ntawm lub chaw tswj hwm hauv cheeb tsam, rov ua dua GS5500 thiab GS5620B chav nyob muab cov ntaub ntawv tseem ceeb thiab lub sijhawm thaub qab. GS5600 aggregates raws li txoj cai los ntawm tag nrho cov substations rau centralized saib xyuas.
Lub sij hawm cov cim qhia tau muab faib rau cov chaw nres tsheb ntawm ob txoj hauv kev: PTP / NTP hla cov khoom siv hluav taws xob WAN (tswj Ethernet), thiab cov sij hawm sib txuas ntawm GS5710 fiber optic kis tau tus mob rau kev tiv thaiv tseem ceeb.
Ntawm txhua qhov chaw nres tsheb, GS5500 lossis GS3100 units tau txais lub sijhawm thiab faib PTP / NTP ntawm LAN hauv zos. GS5210 units tsim 1PPS, 10MHz, thiab IRIG-B rau legacy relays thiab PMUs. Dual-input redundancy ua kom tsis siv neeg poob ntawm WAN lub sij hawm txoj kev thiab ib qho chaw txais GPS hauv zos.
