Qhov sib txawv ntawm Kev Lag Luam thiab Kev Lag Luam Kev Lag Luam Kev Lag Luam thiab Kev Siv Hluav Taws Xob-Scale Energy Storage

Lub zog cia tau txais kev muaj koob meej raws li qhov tseem ceeb ntxiv rau cov khoom siv hluav taws xob tauj dua tshiab.Ntawm cov khoom siv hluav taws xob, kev lag luam thiab kev lag luam kev lag luam thiab kev siv hluav taws xob-teev hluav taws xob cia yog ob qho kev daws teeb meem uas tau tshwm sim nyob rau xyoo tas los no.Txawm li cas los xij, lawv muaj qhov sib txawv ntawm daim ntawv thov scenarios thiab kev ua haujlwm.Kab lus no yuav piav qhia txog qhov sib txawv ntawm ob hom kev siv hluav taws xob cia los ntawm ntau qhov ntev.

Application Scenarios

C&I lub zog cia yog tsuas yog siv rau tus kheej lub zog ntawm kev lag luam thiab cov neeg siv khoom lag luam uas suav nrog cov chaw tsim khoom, cov tsev, cov chaw khaws ntaub ntawv, thiab lwm yam. Lub hom phiaj yog los txo cov nqi hluav taws xob hauv hav rau cov neeg siv thiab txhim kho kev ntseeg tau ntawm cov khoom siv hluav taws xob.

Utility-scale zog cia yog tsuas yog siv rau sab kab sib chaws.Lub hom phiaj yog kom sib npaug ntawm cov khoom siv hluav taws xob thiab kev xav tau, tswj cov kab hluav taws xob ntau zaus, thiab ua tiav cov kev cai siab-koob hav.Nws kuj tseem tuaj yeem muab lub peev xwm seem thiab lwm yam kev tswj xyuas hluav taws xob.

Cmuaj peev xwm

Lub peev xwm ntawm C&I lub zog cia yog feem ntau nyob rau hauv thaj tsam ntawm ntau kaum mus rau pua pua ntawm kilowatt-teev, feem ntau nyob ntawm tus neeg siv qhov loj me thiab cov nqi se.Lub peev xwm ntawm ultra-loj-scale C&I systems feem ntau tsis tshaj 10,000 kWh.

Lub peev xwm ntawm kev siv hluav taws xob-teev hluav taws xob cia nyob ntawm ntau lub megawatt-teev mus rau ntau pua megawatt-teev, sib piv cov kab sib chaws thiab kev xav tau.Rau qee qhov phiaj xwm loj-theem, lub peev xwm ntawm ib qhov chaw tuaj yeem ncav cuag ntau pua megawatt-teev.

Qhov System Cheebtsam

· Roj teeb

C&I lub zog cia yuav tsum muaj lub sijhawm teb tsawg.Kev txiav txim siab txog cov nqi, lub voj voog lub neej, lub sijhawm teb thiab lwm yam, cov roj teeb uas muaj zog ceev raws li qhov tseem ceeb yog siv.Utility-scale lub zog cia siv lub zog ceev tsom rau cov roj teeb rau kev tswj hwm zaus.

Qhov tseeb, feem ntau ntawm cov khoom siv hluav taws xob loj kuj tseem siv cov roj teeb uas muaj zog ceev ua qhov tseem ceeb.Tab sis txij li thaum lawv yuav tsum tau muab cov kev pabcuam hluav taws xob ntxiv, cov roj teeb lub zog ntawm cov chaw nres tsheb fais fab muaj cov kev xav tau siab dua rau lub neej voj voog thiab lub sijhawm teb.Cov roj teeb uas siv rau kev tswj hwm zaus thiab thaum muaj xwm txheej ceev yuav tsum xaiv cov roj teeb hluav taws xob.

· Roj teeb tswj System (BMS)

Lub tshuab me me thiab nruab nrab C&I lub zog khaws cia tuaj yeem muab cov roj teeb ntim nrog ntau yam kev tiv thaiv, xws li overcharging, over-discharging, over-current, overheating, under-temperature, short-circuit and tam sim no txwv.Nws kuj tseem tuaj yeem sib npaug ntawm qhov hluav taws xob ntawm lub roj teeb pob thaum lub sij hawm them nqi, teeb tsa cov kev txwv thiab saib xyuas cov ntaub ntawv los ntawm cov software keeb kwm yav dhau, sib txuas lus nrog ntau hom kev hloov hluav taws xob, thiab ua kom muaj kev tswj hwm ntawm tag nrho lub zog cia.

Lub chaw nres tsheb fais fab fais fab tuaj yeem tswj hwm cov roj teeb ntawm tus kheej, cov roj teeb pob thiab cov roj teeb sib txuas ua ke raws li hierarchical.Raws li lawv cov yam ntxwv, ntau yam tsis sib xws thiab kev ua haujlwm ntawm cov roj teeb tuaj yeem suav thiab txheeb xyuas kom ua tiav qhov sib npaug, tswb thiab kev tswj hwm zoo.Qhov no tso cai rau txhua pab pawg ntawm cov roj teeb los tsim cov zis tib yam, kom ntseeg tau tias lub kaw lus ua tiav lub xeev ua haujlwm zoo tshaj plaws thiab siv sijhawm ntev tshaj plaws.Qhov no muab cov ntaub ntawv tswj cov roj teeb kom raug thiab siv tau zoo.Los ntawm kev tswj cov roj teeb ntsuas, lub zog siv hluav taws xob ntawm cov roj teeb tuaj yeem txhim kho tau zoo thiab cov yam ntxwv thauj khoom tau zoo.Nyob rau tib lub sijhawm, kev pabcuam lub neej ntawm cov roj teeb tuaj yeem ua rau kom muaj kev ruaj ntseg, kev nyab xeeb thiab kev ntseeg siab ntawm lub zog cia.

· Fais Fab Tswj System (PCS)

Cov inverters siv hauv C&I lub zog cia muaj cov haujlwm yooj yim, feem ntau yog hloov pauv hloov hluav taws xob bidirectional, me me, thiab yooj yim rau kev koom ua ke nrog cov roj teeb.Lub peev xwm yuav hloov tau yooj yim raws li xav tau.Lub inverters tuaj yeem hloov mus rau qhov dav dav ntawm 150-750 volts, ua tau raws li cov kev sib txuas thiab cov kev sib txuas ntawm cov roj ntsha txhuas-acid, lithium roj teeb, cov roj teeb ntws thiab lwm yam roj teeb, thiab ua tiav unidirectional them thiab tso tawm.Lawv kuj tuaj yeem phim ntau hom photovoltaic inverters.

Cov inverters siv nyob rau hauv lub zog cia fais fab chaw nres tsheb muaj dav DC voltage ranges, mus txog 1500 volts rau tag nrho cov load.Ntxiv rau qhov yooj yim zog hloov dua siab tshiab muaj nuj nqi, lawv kuj yuav tsum muaj daim phiaj-coordinated functions, xws li thawj zaus kev cai, ceev qhov chaw-grid-load dispatching, thiab lwm yam. Lawv muaj zog daim phiaj adaptability thiab muaj peev xwm ua tau ceev zog teb.

· Kev Tswj Xyuas Hluav Taws Xob (EMS)

Feem ntau ntawm EMS ntawm C&I lub zog cia tshuab tsis tas yuav txais daim phiaj xa tawm.Lawv lub luag haujlwm tseem ceeb, tsuas yog xav tau kev tswj hwm lub zog hauv zos, uas yog txhawb nqa kev tswj hwm roj teeb, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm, txhawb cov lus teb ceev millisecond, thiab ua tiav kev tswj hwm kev sib koom ua ke thiab kev tswj hwm hauv nruab nrab ntawm cov khoom siv hluav taws xob sub-system.

Txawm li cas los xij, kev siv hluav taws xob-txhim hluav taws xob xws li lub zog cia hluav taws xob chaw nres tsheb uas yuav tsum tau txais daim phiaj xa hluav taws xob muaj qhov xav tau siab dua rau EMS.Ntxiv nrog rau kev tswj hwm kev siv hluav taws xob yooj yim, lawv kuj yuav tsum tau muab cov phiaj xwm xa tawm cuam tshuam thiab kev tswj hwm lub zog rau micro-grid systems.Lawv yuav tsum tau txhawb nqa ntau txoj kev sib txuas lus, muaj cov qauv siv hluav taws xob xa hluav taws xob sib txuas, muaj peev xwm tswj hwm kev tswj hwm hluav taws xob thiab saib xyuas cov ntawv thov xws li hloov hluav taws xob, micro-grids, thiab kev tswj fais fab zaus, thiab txhawb kev sib txuas ntxiv thiab saib xyuas ntau lub tshuab xws li cov khoom siv hluav taws xob, kab sib chaws, kev thauj khoom, thiab lub zog cia.
