Kutheni iBhili yaMandla yeeNkampu zezeMigodi ibuhlungu ngakumbi nangakumbi?
Inkampu yemigodi yindawo eqhelekileyo engekho kwigridi, ukusetyenziswa kwamandla aphezulu: iindawo zokulala, iicanteens, ugutyulo lwelindle kunye nokugcinwa kwezixhobo zonke zifuna amandla angaphazanyiswa angama-24/7.
Isisombululo semveli sasinokhetho olunye kuphela - iijeneretha zedizili.
Ityala le-diesel longeza kabuhlungu. Amaxabiso epetroli adla ngokufikelela kuma-60% ukuya kuma-80% exabiso lilonke lokusebenzisa umbane wedizili; kwiindawo ezikude zemigodi, amandla avela kwidizili anokubiza amaxesha angama-3-4 ixabiso lombane wegridi.
Ngokwezibalo ze-Xuzhou Zm-Besta kwizicelo zemigodi: i-portal yomgodi omnye i-avareji ye-200-400 kW yomthwalo, iiyure eziyi-12-16 zokusebenza kwemihla ngemihla kunye ne-0.8-2 yezigidi ze-kWh zokusetyenziswa kombane ngonyaka; i-10,000 m² inkampu yokwakha i-avareji ye-50-80 kW yomthwalo kunye ne-15,000-29,000 kWh yokusetyenziswa kombane ngenyanga.
Kuqikelelo lwexabiso lokuvelisa idizili eyi-6.71 yeesenti/kWh, inkampi enye yemigodi inokuchitha ukusuka kumakhulu amawaka ukuya ngaphezulu kwesigidi seedola zaseMelika kwidizili minyaka le - phambi kokubala ingxolo, izinto ezikhutshwayo kunye nemingcipheko yezothutho zetanki yamafutha.
Isisombululo sesolar diesel hybrid microgrid kwiinkampu zemigodi (ekwabizwa ngokuba yindawo yomgodi microgrid) kukuba: umbane welanga, ugcino lwamandla ekuchebeni okuphezulu, kunye neejenereyitha zedizili ezithotyelwe "kwindawo yokugcina yokugcina." Esi sisombululo samandla ombane angaphandle kwegrid siphumeza indawo yogcino lwesola yejenereyitha yedizili.
Ukusuka kwi-Diesel Grid-Forming ukuya kwiSolar Diesel Hybrid Microgrid Grid-Forming: IiMetrics eziphambili ukusuka kwiiMvavanyo zoTshintsho
“Ukwenziwa kwegridi” kubhekiselele kumthombo ochaza amandla ombane wenkqubo kunye namaxesha. Kulo lonke ixesha le-diesel, i-diesel generator yayikuphela komthombo wokwenza igridi; emva kokutshintshela kwi-solar diesel hybrid microgrid grid-forming, i-inverter ithatha i-voltage/frequency control ngelixa i-generator ye-diesel iyaziqalisa kwaye ime njenge-backup.
Uthelekiso lobugcisa lweXuzhou Zm-Besta kwimeko yenkampu ye-100 kW:
Isicwangciso esingundoqo sokutshintsha siyalandela “i-solar priority, isongezelelo sokugcina, i-backup ye-diesel“: amandla elanga angaphezulu agcinwe ebhetrini; ngexesha elibi kakhulu lemozulu yezulu / imvula okanye xa i-SOC yokugcina iwela ngaphantsi kwe-20%, i-diesel generator iqala ngokuzenzekelayo kwaye ivumelanise, kunye nexesha lokutshintsha kwe-≤10 ms yokunikezelwa kwamandla okungenamthungo.
ISolar Diesel Hybrid Microgrid System Savings Diesel: Ukuya kuthi ga kwi-90%
Eli linani abathengi abalikhathalele kakhulu.
Ukubala kweXuzhou Zm-Besta (inkampu ye-100 kW, umjikelo weminyaka emi-5, umsebenzi oqhubekayo weeyure ezingama-24):
| Into | I-Diesel-Only Solution | ISolar Diesel Hybrid Microgrid Solution |
| Iindleko zokusebenza zonyaka | I-USD 58,750 (i-diesel: i-USD 55,000; ukugcinwa: ii-USD 3,750) | I-USD 5,833.33 (i-O&M yesiqhelo: i-USD 1,666.67; ubonelelo lokutshintshwa kwebhetri: USD 2,777.78; idizili yexesha likaxakeka: USD 1,388.89) |
| Ugcino lonyaka | – | I-USD 52,916.67, ukunciphisa i-90.1% |
| Iindleko nge-kWh nganye (ithathwe kuguqulelo lwe-RMB) | Malunga. 6.71 US iisenti/kWh | Malunga. I-1.04 yeesenti zase-US/kWh, ukuncipha kwe-84.5% |
Kulo lonke ishishini, ukusetyenziswa kwedizili kuncitshiswe ngama-50% -90%.
Uphononongo: Emva kokuba i-solar diesel hybrid microgrid yokusebenza kwemigodi yaseZimbabwe iqalile ukusebenza, ukusetyenziswa kwedizili ngonyaka kwehle ngaphezulu kwe-90%, konga malunga ne-USD 6.948 yezigidi kwiindleko zamafutha ngonyaka; kumgodi waseChile, i-solar hybrid diesel hybrid microgrid inqumle ukusetyenziswa kwedizili ukusuka kwi-980,000 ilitha ukuya kwi-468,000 ilitha kunyaka wayo wokuqala, ukuncipha kwe-52.2%.
Ukuzinza kweNkqubo: Njani i-99.9% yoNikezo lwaMandla oluqhubekayo luphunyezwa
Iinkampu zemigodi azikunyamezeli kwaphela ukucima kombane. Ukuthembeka kwesolar diesel hybrid microgrid kuxhomekeke kuyilo olunemigangatho emihlanu:
I-N+1 ye-Architecture engafunekiyo
Ilanga, ukugcinwa kunye neejenereyitha zedizili zibuyisela enye kwenye; inqaku elinye lokungaphumeleli alichaphazeli unikezelo lwamandla lulonke, ngokujoliswe kuko okuthembekileyo kwe-99.9%.
ULawulo lwaMandla oBukrelekrele be-EMS
Ixesha lokwenyani lokujongwa kwemveliso yelanga, i-SOC yokugcina, ubume bomthwalo kunye ne-diesel generator kunye nokuthunyelwa okuzenzekelayo; ixhasa esweni ukude nge-app ephathwayo/ikhompyuter kunye nokusebenza okungajongwanga.
Ukukwazi ukuqalisa uMnyama
Emva kokuvalwa kwenkqubo epheleleyo, inokubuyisela ngokukhawuleza ngokwayo ngaphandle komthombo wamandla wangaphandle.
Unikezelo lwamandla olungaphazamisekiyo lwe-UPS
Ibonelela ngokhuseleko olungaphazamisiyo kwimithwalo ebuthathaka ngexesha lokutshintsha kwamandla, ukuphelisa ukulahleka kwedatha kunye nexesha lokuphumla kwezixhobo.
Ukugcinwa kunye noNyamezelo lweZixhobo
I-Lithium iron phosphate (LiFePO4) iibhetri ezinobomi bomjikelezo we-5,000-8,000 imijikelezo kunye nokuchaneka koqikelelo lwe-SOC ≤3%; ukusebenza kakuhle kwe-inverter ≥95% kunye neMPPT yokulandelela umkhondo ≥99%; iiyunithi zesikhululo samandla elanga esinezikhongozeli zilinganiswe nge-IP55, zimiselwe ukuxhathisa imimoya yenqanaba lesi-9 xa zibekiwe, kwaye zisebenza ukusuka ku--20°C ukuya ku-+50°C, nto leyo eyenza ukuba ifanelekele iindawo ezirhabaxa zemigodi.
Umzekelo weshishini: i-solar diesel hybrid microgrid kwishishini lokulungisa intsimbi ekrwada eNtshona Australia ifumene ukufumaneka kwama-98.7% kwiinyanga ezili-18 zokusebenza; I-solar diesel hybrid microgrids ifikelela kwintembeko yonikezelo engaphezulu kwe-99.9%.
Imibuzo Ebuzwa Rhoqo
I-Q1: Yiyiphi uluhlu lwamandla eenkampu zemigodi yilanga idizili eyihybrid microgrid ifanelekile?
A: 20kW–200kW iiyunithi zesikhululo samandla elanga eziqulathiweyo zigubungela ukusuka kwiindawo zokuhlala iiprojekthi ukuya kwimigodi emikhulu; Ulungelelwaniso lwe-100-500 kW lunceda imigodi emikhulu evulekileyo, evelisa malunga nama-600,000 kWh ngonyaka kwaye ithatha indawo emalunga neetoni ezili-150 zedizili.
Q2: Ngaba utshintshe ukusuka kwidizili ukuya ugcino lwelanga zibangele ukungasebenzi kwezixhobo?
A: Ixesha lethu lokutshintsha ngu-≤10 ms, kude ngaphantsi komda onokuthi izixhobo ziwubone; I-UPS iphinda ixhase imithwalo ebalulekileyo, ngoko akukho kuphazamiseka kwamandla ngexesha lokutshintsha.
Q3: Kuthekani ngeentsuku ezilandelelanayo ezinamafu okanye ezinetha?
A: Umthamo wogcino uqhele ubungakanani beentsuku ezi-3-7 ezilandelelanayo ezinamafu/iimvula; xa i-SOC yokugcina iwela ngaphantsi kwe-20% okanye kwimozulu embi, i-diesel generator iqala ngokuzenzekelayo ukunyusa amandla.
Q4: Ingakanani imali yedizili onokuthi uyiqinisekise?
A: Ngokubanzi 50%–90%. Umda ophezulu we-Xuzhou Zm-Besta yi-90.1%; Okwenyani kuxhomekeke ekukhanyeni kwelanga kunye negophe lomthwalo.
I-Q5: Kuthatha ixesha elingakanani ukuhambisa isikhongozeli amandla elanga isitishi?
A: Idityaniswe kwangaphambili kwaye ithunyelwe kwangaphambili kwi-factory, ingasetyenziselwa ukuvelisa amandla kwi-1 yeyure emva kokufika kwisiza. Ngokomzekelo, i-container ye-20-foot ithatha malunga nemizuzu engama-80 ukuba abasebenzi aba-6 basebenze ngokupheleleyo.
I-Q6: Ngaba inkqubo inokulawulwa kude?
A: Ewe. I-EMS ehlakaniphile isekela ukubeka iliso kude kunye nokulawula ukuqala / ukumisa isixhobo nge-app yeselula / ikhompyutha, ivumela ukusebenza kunye nokugcinwa okungakhathalelwanga.
Ukuba uceba isisombululo samandla ombane ongekho kwigridi okanye isistim yamandla ekude kwinkampu yendawo yemigodi, iindawo zokwakha, okanye iinkampu ezikude, wamkelekile ukuqhagamshelana neXuzhou Zm-Besta.
