1. Daim ntawv thov Scenario
Nyob rau hauv cov txheej txheem ntawm kev tsim kho sab nraum zoov, cov cuab yeej hluav taws xob uas feem ntau suav nrog kev siv lub zog ntawm tus kheej (roj teeb module) thiab cov khoom siv hluav taws xob sab nraud feem ntau siv. Cov cuab yeej hluav taws xob nrog lawv tus kheej cov khoom siv hluav taws xob tuaj yeem ua haujlwm ntawm cov roj teeb rau lub sijhawm, thiab lawv tseem cia siab rau cov khoom siv hluav taws xob sab nraud rau kev siv mus ntev; Cov cuab yeej hluav taws xob uas tso siab rau cov khoom siv hluav taws xob sab nraud kuj xav tau lub zog hluav taws xob ua haujlwm ib txwm.
Tam sim no, cov tshuab hluav taws xob diesel feem ntau yog siv los muab lub zog rau cov khoom siv hluav taws xob rau kev tsim kho sab nraum zoov. Muaj ob lub laj thawj tseem ceeb. Qhov chaw cia khoom kho qhov muag AC tawm ntawm daim phiaj hluav taws xob yuav yog qhov kev xaiv zoo dua. Ua ntej ntawm tag nrho cov, nws yog ib qho nyuaj heev rau refuel lub diesel generator teeb. Txawm lub chaw nres tsheb roj av nyob deb heev los yog lub chaw nres tsheb roj yuav tsum tau muab daim ntawv pov thawj ntawm tus kheej, uas ua rau refueling teeb meem heev; Qhov thib ob, qhov zoo ntawm cov hluav taws xob tsim los ntawm cov tshuab hluav taws xob diesel yog qhov tsis zoo, ua rau muaj ntau yam khoom siv hluav taws xob hlawv hauv lub sijhawm luv luv. Tom qab ntawd, qhov chaw cia khoom kho qhov muag AC tawm ntawm daim phiaj hluav taws xob tsis tas yuav nrhiav chaw nres tsheb roj. Ntev npaum li huab cua zoo li qub, nws yuav ua rau lub zog txuas ntxiv, thiab qhov zoo ntawm lub zog tsim hluav taws xob kuj tseem ruaj khov, uas tuaj yeem hloov pauv lub zog hauv nroog.
2. Qhov System Design
Lub PV cia thiab fais fab mov system txais kev koom ua ke DC tsheb npav tshuab, organically sib txuas lub tshuab hluav taws xob photovoltaic, roj teeb lub zog cia subsystem, DC tis system thiab lwm yam subordinate systems, thiab ua kom tag nrho kev siv lub zog huv si, ntsuab tsim los ntawm lub hnub ci zog. ruaj khov muab lub zog rau cov khoom siv hauv tsev. Lub kaw lus muab AC 220V thiab DC 24V fais fab khoom siv. Lub kaw lus siv lub roj teeb lub zog cia subsystem kom tsis txhob siv hluav taws xob thiab kho lub zog sib npaug sai; Lub tshuab hluav taws xob tag nrho muab kev nyab xeeb, txhim khu kev qha thiab ruaj khov lub peev xwm rau cov tsev neeg thiab lub tsev kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob ntawm ntau yam khoom siv hauv tsev thiab teeb pom kev zoo.

4. Cov xwm txheej
Qhov chaw: Tuam Tshoj Qinghai
System: hnub ci AC tawm daim phiaj fais fab mov system
Nqe lus piav qhia:
Raws li qhov project site nyob ze li ntawm 400km deb ntawm qhov chaw nres tsheb roj ze tshaj plaws, lub zog thov rau kev tsim kho sab nraum zoov yog qhov siab heev. Tom qab ob peb tham nrog cov neeg siv khoom, nws tau txiav txim siab siv PV cia AC tawm ntawm daim phiaj hluav taws xob los muab lub zog rau kev tsim kho sab nraum zoov. Cov khoom siv hluav taws xob tseem ceeb suav nrog cov cuab yeej hluav taws xob ntawm qhov chaw thiab chav ua noj thiab cov khoom siv nyob ntawm cov neeg ua haujlwm tsim kho.
Lub tsev tsim hluav taws xob photovoltaic tau tsim nyob rau hauv qhov chaw qhib tsis deb ntawm qhov chaw ua haujlwm, thiab cov txheej txheem rov tsim kho tshuab tau txais los ua kom yooj yim rov txhim kho thiab kho. PV cia tag nrho-hauv-ib lub tshuab kuj muaj cov yam ntxwv ntawm kev teeb tsa thiab rov siv dua. Ntev npaum li nws tau teeb tsa ua ntu zus raws li phau ntawv qhia kev teeb tsa, cov khoom siv sib dhos tuaj yeem ua tiav. Yooj yim thiab txhim khu kev qha!
Kev tsim kho sau ntawv: kev teeb tsa ntawm photovoltaic modules yuav tsum tau ua kom muaj kev txhim kho ntawm cov array thiab xyuas kom meej tias photovoltaic array yeej't raug puas tsuaj los ntawm cov cua muaj zog nyob rau hauv huab cua.
5.Kev ua lag luam muaj peev xwm
Lub PV cia AC off grid fais fab mov system siv lub hnub ci zog ua lub zog tsim hluav taws xob thiab roj teeb lub zog cia ua lub zog cia kom ua tiav kev siv lub hnub ci tsim hluav taws xob los muab lub zog rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv chav ua noj. Nyob rau yav tav su lossis hmo ntuj thaum lub hnub tsis zoo lossis tsis muaj hnub ci, lub zog ntawm lub tshuab hluav taws xob diesel tuaj yeem txuas ncaj qha los muab lub zog rau cov khoom siv hluav taws xob tseem ceeb.
Kev txhim kho tsis tu ncua ntawm kev tsim kho sab nraum zoov yuav tsum tau txais kev txhawb nqa los ntawm lub zog txaus thiab txhim khu kev qha. Piv nrog rau cov tsoos diesel generator teeb, PV cia AC tawm ntawm daim phiaj hluav taws xob muaj qhov zoo ntawm kev teeb tsa ib zaug, tuaj yeem txhawb nqa mus txog qhov kawg ntawm qhov project, thiab tsis tas yuav tawm mus yuav roj ntau zaus. ; Nyob rau tib lub sijhawm, lub zog zoo ntawm lub zog muab los ntawm cov khoom siv hluav taws xob no kuj zoo heev, uas tuaj yeem tiv thaiv kev nyab xeeb thiab ua kom lub neej ntev ntawm cov khoom siv hluav taws xob ntawm qhov chaw tsim kho.
Lub PV cia AC tawm ntawm daim phiaj hluav taws xob tuaj yeem muab cov khoom siv hluav taws xob txuas ntxiv thiab ruaj khov zoo rau kev tsim kho sab nraum zoov thiab ua kom muaj kev kub ceev ntawm kev tsim kho. Lub kaw lus nws tus kheej yog lub zog siv hluav taws xob uas tuaj yeem ntsia tau thiab siv tau ntau zaus los ua kom tag nrho cov khoom siv hluav taws xob hnub ci. Txij li cov nqi hluav taws xob hnub ci tsim hluav taws xob pheej yig heev, nws yuav tsum yog qhov kev xaiv zoo rau nruab ib txheej ntawm PV cia AC tawm ntawm daim phiaj hluav taws xob rau ntawm qhov chaw tsim kho sab nraum zoov.
