Substation Roj Teeb Saib Xyuas: Kev Tshawb Fawb Thaum Ntxov, Kev Ua Haujlwm Zoo, thiab kev sib koom ua ke yooj yim

Cov chaw ua haujlwm niaj hnub no nyob ntawm DC cov roj teeb ua haujlwm los ua haujlwm tiv thaiv relays, Circuit Court breakers, SCADA cov cuab yeej, kev sib txuas lus, thiab teeb pom kev zoo thaum muaj hluav taws xob. Yog tias ib qho tsis muaj zog ntawm tes tsis ua haujlwm, kev ntseeg siab ntawm tag nrho cov hlua roj teeb yuav raug cuam tshuam.

Lub substation roj teeb xyuas qhov system muab kev pom tsis tu ncua rau hauv cov roj teeb. Los ntawm kev saib xyuas txhua lub xov tooj ntawm tes thiab roj teeb hauv lub sijhawm tiag tiag, cov khoom siv hluav taws xob tuaj yeem tshawb pom cov cim qhia ntxov ntawm kev puas tsuaj, txo cov kev tshuaj xyuas phau ntawv, thiab tiv thaiv kev poob siab ntawm DC fais fab tuag.

Vim li cas Substation Roj Teeb Saib Xyuas yog qhov tseem ceeb

Substation roj teeb feem ntau nyob twj ywm ntawm tus nqi ntab rau ntau xyoo. Nyob rau lub sijhawm no, kev laus, kev xeb, kev sib txuas xoob, teeb meem them nyiaj, thiab kev hloov pauv kub tuaj yeem txhim kho yam tsis muaj cov tsos mob pom tseeb.

Kev tshuaj xyuas ib ntus tsuas yog qhia txog lub sijhawm ntawm lub roj teeb. Hauv kev sib piv, lub tshuab hluav taws xob hluav taws xob hauv online ua haujlwm 24/7 thiab txheeb xyuas qhov txawv txav ua ntej lawv cuam tshuam rau cov khoom siv tseem ceeb.

Kev saib xyuas tsis tu ncua pab kev siv hluav taws xob:

• Tshawb xyuas cov hlwb uas tsis muaj zog lossis ua kom tsis zoo thaum ntxov
• Tiv thaiv kev tiv thaiv relay thiab Circuit Court breaker tsis ua hauj lwm
• Txo cov txheej txheem kev soj ntsuam xyuas ua haujlwm
• Txhim kho cov neeg ua haujlwm thiab khoom siv kev nyab xeeb
• Txhawb kev kho mob raws li lub roj teeb
• Ua kom substation DC qhov kev ntseeg tau

Tej yam txaus ntshai nyob rau hauv Unmonitored DC Battery Systems

Roj teeb tsis ua hauj lwm feem ntau yuav maj mam es tsis tshwm sim yam tsis muaj ceeb toom. Ib qho kev txhim khu kev qha DC roj teeb saib xyuas tuaj yeem txheeb xyuas ntau yam ntawm cov teeb meem no los ntawm qhov hluav taws xob, tsis kam, kub, thiab cov qauv tam sim no.

Tej yam txaus ntshai muaj xws li:

• Roj teeb aging thiab muaj peev xwm poob
• Ua kom muaj zog sab hauv
• Cell voltage imbalance
• Loose los yog corroded terminal kev twb kev txuas
• Lub roj teeb kub tsis zoo
• Charger lossis float-tam sim no txawv txav
• Ripple tam sim no thiab hlua imbalance

Yog tsis muaj kev saib xyuas tas mus li, cov xwm txheej no yuav raug muab zais kom txog thaum lub roj teeb yuav tsum tau ua thaum muaj xwm txheej ceev.

Ni-Cd thiab VRLA Battery Monitoring

Cov chaw nres tsheb hluav taws xob feem ntau siv Nickel-Cadmium (Ni-Cd), Valve-Regulated Lead-Acid (VRLA), lossis cov roj ntsha lead-acid. Txhua chemistry yuav tsum muaj lub tswv yim zoo saib xyuas.

Ni-Cd Roj Teeb Saib Xyuas

Ni-Cd roj teeb saib xyuas yuav tsum tsom rau ntawm tus kheej ntawm lub xov tooj ntawm tes, kev them nyiaj, qhov kub thiab txias, kev laus ntawm electrolyte, thiab txoj hlua ua haujlwm. Vim hais tias kev hloov pauv sab hauv tuaj yeem hais tau tsawg dua li ntawm VRLA roj teeb, qhov ntev ntawm qhov hluav taws xob thiab kev them nqi yog qhov tseem ceeb.

VRLA Roj Teeb Saib Xyuas

VRLA roj teeb xyuas feem ntau tsom rau ntawm tes hluav taws xob, kev tiv thaiv sab hauv, kub, them tam sim no, thiab muaj peev xwm degradation. Ib qho kev nce ntxiv hauv kev tiv thaiv tuaj yeem muab kev ceeb toom ntxov ntawm roj teeb kev laus thiab txo qis kev muaj peev xwm rov qab.

Lub roj teeb hloov pauv hloov pauv kev soj ntsuam yuav tsum txhawb Ni-Cd, VRLA, VLA, thiab lithium roj teeb ntawm ib lub platform.

Dab tsi yuav tsum tau ib tug substation roj teeb xyuas ntsuas?

Ib qho kev ua tau zoo yuav tsum saib xyuas ob leeg tib neeg lub hlwb thiab cov hlua roj teeb ua tiav. Cov tsis tseem ceeb tshaj plaws suav nrog cov hauv qab no.

Cell Voltage

Kev ntsuas hluav taws xob tas mus li ntawm tes ntsuas pom cov hlwb tsis muaj zog, overcharging, undercharging, thiab voltage imbalance. Txawm tias ib qho kev sib txawv me me tuaj yeem qhia tau tias muaj kev ua txhaum loj.

Roj teeb kub

Qhov kub thiab txias ua rau lub roj teeb laus zuj zus, thaum qhov kub tsis sib xws yuav qhia tau tias qhov cua tsis zoo, teeb meem them, lossis cov hlwb tsis zoo. Real-time kub tswb tswb pab tiv thaiv thermal puas.

Internal Resistance

Internal resistance yog ib qho tseem ceeb tshaj plaws qhia txog roj teeb deterioration. Kev soj ntsuam zoo tuaj yeem nthuav tawm kev laus ntev ua ntej qhov peev xwm poob tau pom tseeb thaum lub sijhawm kuaj tawm.

Txoj hlua voltage thiab tam sim no

Txoj hlua hluav taws xob, ntab tam sim no, them nqi / tawm tam sim no, thiab ripple tam sim no muab cov ntaub ntawv tseem ceeb txog kev ua haujlwm ntawm lub charger thiab tag nrho cov roj teeb.

Terminal thiab kev twb kev txuas

Loos los yog corroded terminals tuaj yeem ua rau muaj hluav taws xob poob thiab cov cua sov hauv zos. Kev kuaj xyuas qhov txawv txav tsis zoo ua rau cov pab pawg saib xyuas kho cov teeb meem no ua ntej lawv dhau los ua kev phom sij.

Kev koom ua ke nrog SCADA thiab Substation Automation

Cov khoom siv hluav taws xob feem ntau xav tau cov ntaub ntawv roj teeb kom muaj los ntawm SCADA, EMS, DCS, lossis kev tswj hwm network. Lub roj teeb niaj hnub saib xyuas cov khoom siv hluav taws xob yuav tsum tau txhawb nqa cov txheej txheem kev sib txuas lus hauv kev lag luam.

Cov kev xaiv sib xyaw ua ke muaj xws li:

• Modbus RTU
• Modbus TCP/IP
• SNMP
• IEC 61850: Ua
• REST API

IEC 61850 roj teeb xyuas yog qhov tseem ceeb tshwj xeeb rau cov chaw nres tsheb digital vim nws yooj yim rau kev sib txuas lus nrog cov khoom siv hluav taws xob ntse thiab cov tshuab hluav taws xob substation automation.

Cov ntsiab lus tseem ceeb rau kev xa tawm qhov system

Ua ntej xaiv lub substation roj teeb xyuas qhov system, engineers yuav tsum paub meej cov ntaub ntawv hauv qab no:

• Roj teeb chemistry thiab nominal cell voltage
• Cov xov tooj ntawm tes thiab cov hlua roj teeb
• Charger thiab DC system configuration
• Yuav tsum tau saib xyuas qhov ntsuas
• RS485, Ethernet, fiber ntau, lossis 4G kev sib txuas lus muaj
• SCADA, EMS, DCS, lossis IEC 61850 kev koom ua ke yuav tsum tau ua
• Sab hauv lossis sab nraum zoov installation ib puag ncig
• Email, SMS, thiab lub tswb ceeb toom platform

Cov kev soj ntsuam sensors yuav tsum tau nruab yam tsis muaj kev cuam tshuam cov roj teeb ua haujlwm thaum twg los tau. Cable routing, rwb thaiv tsev, electromagnetic compatibility, thiab hluav taws xob cov txheej txheem kev nyab xeeb yuav tsum tau txiav txim siab.

Ntse Tswb thiab Predictive Maintenance

Cov txheej txheem kev tshaj lij yuav tsum muab ntau tshaj li cov ntaub ntawv raw. Lub tswb ntau theem, cov xwm txheej keeb kwm, thiab cov ntawv ceeb toom tsis siv neeg pab engineers nkag siab tias lub xov tooj ntawm tes yog qhov txawv txav, sai npaum li cas nws deteriorating, thiab thaum yuav tsum tau kho.

Cov haujlwm tseem ceeb suav nrog:

• Real-time cell thiab hlua tswb
• Voltage, kub, thiab kev tiv thaiv kev ntsuas
• Kev txheeb xyuas qhov tsis muaj zog
• Cov ntsiab lus ntawm roj teeb kev noj qab haus huv
• Alarm keeb kwm thiab kev saib xyuas cov ntaub ntawv
• Chaw taws teeb tswj ntau qhov chaw

Qhov no ua rau cov khoom siv hluav taws xob txav los ntawm kev hloov pauv mus rau kev saib xyuas raws li txoj cai, txo qis kev mus ntsib qhov chaw tsis tsim nyog thiab cov nqi hloov roj teeb.
