Vim li cas Tus Nqi Fais Fab rau Mining Camps Mob Ntau thiab Ntau?
Lub chaw ua haujlwm mining yog ib qho chaw tawm-daim phiaj, kev siv hluav taws xob siab: cov tsev so, tsev noj mov, kev kho dej phwj tuaj thiab cov khoom siv tu txhua qhov xav tau tsis muaj kev cuam tshuam lub zog 24/7.
Cov tshuaj ib txwm muaj tsuas yog ib qho kev xaiv - diesel generators.
Daim nqi diesel ntxiv qhov mob. Cov nqi roj feem ntau suav txog 60% -80% ntawm tag nrho cov nqi khiav lag luam ntawm lub tshuab hluav taws xob diesel; nyob rau hauv tej thaj chaw deb mining, diesel-tsim hluav taws xob tuaj yeem raug nqi 3-4 npaug ntawm daim phiaj hluav taws xob.
Raws li Xuzhou Zm-Besta cov txheeb cais ntawm kev siv tsuas yog: ib qho mine portal nruab nrab ntawm 200-400 kW ntawm kev thauj khoom, 12-16 teev ntawm kev ua haujlwm txhua hnub thiab 0.8-2 lab kWh ntawm kev siv hluav taws xob txhua xyoo; ib lub 10,000 m² kev tsim kho chaw pw hav zoov nruab nrab yog 50-80 kW ntawm kev thauj khoom thiab 15,000-29,000 kWh ntawm kev siv hluav taws xob txhua hli.
Ntawm qhov kwv yees cov nqi tsim hluav taws xob ntawm 6.71 US xees / kWh, ib lub chaw ua haujlwm tsuas tuaj yeem siv los ntawm ntau pua txhiab mus rau ntau tshaj li ib lab US las rau diesel txhua xyoo - ua ntej txawm suav cov suab nrov, emissions thiab roj-tanker thauj khoom txaus ntshai.
Kev daws teeb meem ntawm lub hnub ci diesel hybrid microgrid rau cov chaw ua haujlwm mining (tseem hu ua mine site microgrid) yog: hnub ci fais fab mov, lub zog cia rau ncov shaving, thiab diesel generators relegated mus rau "qhov kawg thaub qab." Qhov kev daws teeb meem off-grid mining fais fab no ua tiav lub tshuab hluav taws xob diesel hloov hnub ci cia.
Los ntawm Diesel Grid-Forming rau Hnub Ci Diesel Hybrid Microgrid Grid-Forming: Qhov Tseem Ceeb Metrics los ntawm Switchover Tests
"Grid-forming" yog hais txog qhov twg los txhais qhov system voltage thiab zaus. Nyob rau hauv tag nrho-diesel era, lub tshuab hluav taws xob diesel yog tib txoj kab sib sau ua ke; Tom qab hloov mus rau hnub ci diesel hybrid microgrid-grid-forming, lub inverter yuav siv sij hawm dhau qhov voltage / zaus tswj thaum lub tshuab hluav taws xob diesel pib pib thiab nres ua thaub qab.
Xuzhou Zm-Besta qhov kev sib piv kev sib piv hauv 100 kW qhov chaw pw hav zoov:
Lub tswv yim hloov pauv tseem ceeb raws li "hnub ci qhov tseem ceeb, cia ntxiv, diesel thaub qab“: tshaj hnub ci zog yog khaws cia rau hauv lub roj teeb; Thaum huab cua huab cua / nag lossis daus los yog thaum khaws cia SOC poob qis dua 20%, lub tshuab hluav taws xob diesel tau pib thiab synchronizes, nrog lub sijhawm hloov pauv ntawm ≤10 ms rau seamless xa hluav taws xob.
Hnub Ci Diesel Hybrid Microgrid System Diesel Txuag: Txog li 90%
Qhov no yog tus naj npawb buyers mob siab rau feem ntau.
Xuzhou Zm-Besta txoj kev suav (100 kW camp, 5-xyoo voj voog, 24-teev kev ua haujlwm tsis tu ncua):
| Yam khoom | Diesel-Tsuas Solution | Hnub Ci Diesel Hybrid Microgrid Solution |
| Tus nqi khiav haujlwm txhua xyoo | USD 58,750 (diesel: USD 55,000; kho: USD 3,750) | USD 5,833.33 ( niaj hnub O&M: USD 1,666.67; kev hloov roj teeb: USD 2,777.78; diesel thaum muaj xwm ceev: USD 1,388.89) |
| Kev txuag nyiaj xyoo | – | USD 52,916.67, txo 90.1% |
| Tus nqi ib kWh (muab los ntawm RMB conversion) | Kwv yees li. 6.71 US cents/kWh | Kwv yees li. 1.04 US cents/kWh, txo 84.5% |
Thoob plaws hauv kev lag luam, kev siv roj av yog txo los ntawm 50% -90%.
Cov ntaub ntawv kawm: Tom qab lub hnub ci diesel hybrid microgrid rau Zimbabwe mining lag luam tau mus rau hauv kev pabcuam, txhua xyoo kev siv roj av poob ntau dua 90%, txuag txog USD 6.948 lab hauv cov nqi roj hauv ib xyoos; Nyob rau hauv Chilean mine, lub hnub ci diesel hybrid microgrid txiav diesel noj los ntawm 980,000 litres rau 468,000 litres hauv thawj xyoo, txo ntawm 52.2%.
Kev ruaj ntseg: Yuav ua li cas 99.9% Kev Siv Hluav Taws Xob txuas ntxiv ua tiav
Mining camps muaj xoom kam rau hluav taws xob. Kev ntseeg tau ntawm lub hnub ci diesel hybrid microgrid nyob ntawm tsib txheej tsim:
N + 1 Kev Tsim Kho Tsis Muaj Cai
Hnub ci, cia thiab diesel generators rov qab ib leeg; ib qho taw tes ntawm kev ua tsis tiav tsis cuam tshuam rau tag nrho cov khoom siv hluav taws xob, nrog lub hom phiaj kev ntseeg siab ntawm 99.9%.
Intelligent EMS Energy Management
Kev saib xyuas lub sijhawm ntawm hnub ci tso zis, cia SOC, thauj khoom thiab lub tshuab hluav taws xob diesel nrog kev xa tawm tsis siv neeg; txhawb kev saib xyuas tej thaj chaw deb ntawm mobile app / computer thiab ua haujlwm tsis muaj neeg saib xyuas.
Black Start Capability
Tom qab lub kaw lus ua tiav, nws tuaj yeem rov qab tau sai ntawm nws tus kheej yam tsis muaj hluav taws xob sab nraud.
UPS Uninterruptible Power Supply
Muab kev tiv thaiv tsis muaj kev cuam tshuam rau rhiab loads thaum lub sij hawm hloov hluav taws xob, tshem tawm cov ntaub ntawv poob thiab cov khoom siv downtime.
Cia thiab khoom kam rau ua
Lithium hlau phosphate (LiFePO4) roj teeb nrog lub neej voj voog ntawm 5,000-8,000 cycles thiab SOC kwv yees qhov tseeb ≤3%; inverter efficiency ≥95% thiab MPPT nrhiav efficiency ≥99%; cov chaw nres tsheb hnub ci lub hnub ci ntim yog IP55 ntsuas, xa tawm kom tiv taus qib 9 cua thaum siv, thiab ua haujlwm los ntawm -20 ° C txog + 50 ° C, ua rau nws tsim nyog rau qhov hnyav mining ib puag ncig.
Piv txwv li kev lag luam: lub hnub ci diesel hybrid microgrid ntawm lub chaw tsim khoom kub ore hauv Western Australia ua tiav 98.7% muaj nyob hauv 18 lub hlis ntawm kev ua haujlwm; hnub ci diesel hybrid microgrids feem ntau ncav cuag kev ntseeg siab ntawm ntau dua 99.9%.
Cov lus nug nquag
Q1: Lub zog npaum li cas ntawm mining camps yog hnub ci Diesel hybrid microgrid haum rau?
A: 20kW-200kW containerized solar power station units npog los ntawm qhov project nyob rau hauv cov mines loj; 100-500 kW configurations pab loj qhib-qhov mines, tsim txog 600,000 kWh ib xyoo thiab hloov li ntawm 150 tons ntawm diesel.
Q2: Yuav hloov ntawm diesel rau hnub ci cia ua rau cov khoom tawg?
A: Peb lub sijhawm hloov pauv yog ≤10 ms, deb ntawm qhov pib uas cov khoom tuaj yeem pom; UPS kuj tseem txhawb nqa cov khoom tseem ceeb, yog li tsis muaj lub zog cuam tshuam thaum lub sijhawm hloov pauv.
Q3: Yuav ua li cas rau huab cua sib law liag los yog nag los hnub?
A: Lub peev xwm cia yog ib txwm loj rau 3-7 hnub sib law liag / los nag; Thaum cia SOC poob qis dua 20% lossis huab cua huab cua, lub tshuab hluav taws xob diesel pib pib lub zog.
Q4: Ntau npaum li cas diesel txuag koj tuaj yeem lav tau?
A: Feem ntau 50% -90%. Xuzhou Zm-Besta qhov zoo tshaj plaws-qhov xwm txheej sab sauv yog 90.1%; qhov tseeb nyob ntawm tshav ntuj thiab load nkhaus.
Q5: Nws siv sijhawm ntev npaum li cas los xa lub thawv ntim khoom hnub ci zog chaw nres tsheb?
A: Pre-assembled thiab pre-commissioned nyob rau hauv lub Hoobkas, nws yuav tsum deployed los tsim lub hwj chim nyob rau hauv tsawg li 1 teev tom qab tuaj txog ntawm qhov chaw. Piv txwv li, lub thawv 20-ko taw yuav siv sijhawm li 80 feeb rau cov neeg coob 6 tus neeg los ua kom tag nrho.
Q6: Lub kaw lus puas tuaj yeem tswj tau nyob deb?
A: Yog. Lub ntse EMS txhawb kev saib xyuas tej thaj chaw deb thiab ntaus pib / nres tswj ntawm mobile app / khoos phis tawj, ua kom tsis muaj kev saib xyuas thiab kev saib xyuas.
Yog tias koj tab tom npaj ib qho kev daws teeb meem tawm-grid mining fais fab kev daws teeb meem lossis lub zog hluav taws xob nyob deb nroog rau thaj chaw mining, chaw tsim kho, lossis chaw pw hav zoov, txais tos hu rau Xuzhou Zm-Besta.
Nyem rau xa cov lus nug, thiab cia peb tsim lub zog daws teeb meem rau koj lub chaw pw hav zoov nrog "Solar ua ntej, diesel ua qhov kawg thaub qab ".
