Chifukwa Chiyani Bili Yamagetsi Yamagawo A Migodi Imapweteka Kwambiri?
Malo ochitira migodi ndi malo omwe amangogwiritsa ntchito magetsi osagwiritsidwa ntchito kwambiri: malo ogona, ma canteens, zotsukira zimbudzi ndi kukonza zida zonse zimafuna mphamvu yosasokoneza 24/7.
Njira yachikhalidwe inali ndi njira imodzi yokha - majenereta a dizilo.
Bilu ya dizilo imawonjezeka mopweteka. Mtengo wamafuta nthawi zambiri umatengera 60% -80% ya ndalama zonse zopangira magetsi a dizilo; m'madera akutali amigodi, magetsi opangidwa ndi dizilo amatha kuwononga nthawi 3-4 mtengo wamagetsi wamagetsi.
Malingana ndi ziwerengero za Xuzhou Zm-Besta pa ntchito za migodi: malo amodzi a mgodi amatha 200-400 kW katundu, maola 12-16 a ntchito tsiku ndi tsiku ndi 0.8-2 miliyoni kWh yamagetsi pachaka; kampu yomanga ya 10,000 m² imakhala ndi mphamvu ya 50-80 kW ndi 15,000-29,000 kWh yamagetsi a mwezi uliwonse.
Pamtengo wopangira dizilo wokwana 6.71 US cents/kWh, msasa umodzi wa migodi utha kuwononga kuyambira mazana masauzande kufika kupitilira miliyoni imodzi ya US dollars kugula dizilo chaka chilichonse - tisanawerenge ngakhale phokoso, utsi ndi ngozi zoyendera matanki amafuta.
Yankho la solar dizilo hybrid microgrid ya misasa ya migodi (yomwe imatchedwanso kuti malo a mine microgrid) ndi: magetsi oyendera dzuwa, kusungirako mphamvu zometa kwambiri, ndi ma jenereta a dizilo omwe amatsitsidwa "zosunga zomaliza." Njira yothetsera magetsi ya migodi yomwe siigwiritsa ntchito pagridi imapangitsa kuti majenereta a dizilo alowe m'malo mwa sola.
Kuchokera Kupanga Gridi ya Dizilo kupita ku Solar Dizilo Hybrid Microgrid-Kupanga Gridi: Mametrics Ofunika kuchokera ku Mayeso a Switchover
"Grid-forming" imatanthawuza komwe gwero limatanthawuza mphamvu yamagetsi ndi ma frequency. Mu nthawi ya dizilo yonse, jenereta ya dizilo inali yokhayo yopangira gridi; mutasinthira ku solar hybrid microgrid grid-forming, inverter imatenga mphamvu yamagetsi/ma frequency pomwe jenereta wa dizilo imadziyamba ndikuyima ngati yosunga zobwezeretsera.
Kuyerekeza kwaukadaulo kwa Xuzhou Zm-Besta mumsasa wa 100 kW:
Njira yayikulu yosinthira imatsatira "Kufunika kwa dzuwa, zowonjezera zosungirako, zosungira dizilo“: surplus solar power imasungidwa mu batire; panyengo yamvula/yamvula kwambiri kapena yosungirako SOC ikatsikira pansi pa 20%, jenereta ya dizilo imangoyamba ndi kulunzanitsa, ndi nthawi yosinthira ≤10 ms popereka mphamvu zopanda msoko.
Solar Dizilo Hybrid Microgrid System Dizilo Kupulumutsa: Mpaka 90%
Iyi ndiye nambala yomwe ogula amasamala kwambiri.
Kuwerengera kwa Xuzhou Zm-Besta (msasa wa 100 kW, kuzungulira kwazaka 5, maola 24 osalekeza):
| Kanthu | Dizilo-Okha Njira | Solar Dizilo Hybrid Microgrid Solution |
| Mtengo wogwirira ntchito pachaka | USD 58,750 (dizilo: USD 55,000; kukonza: USD 3,750) | USD 5,833.33 (nthawi zonse O&M: USD 1,666.67; kupatsa batire m'malo: USD 2,777.78; dizilo yadzidzidzi: USD 1,388.89) |
| Ndalama zosungira pachaka | – | USD 52,916.67, kuchepetsa 90.1% |
| Mtengo pa kWh (yochokera ku kutembenuka kwa RMB) | Pafupifupi. 6.71 US senti/kWh | Pafupifupi. 1.04 US senti/kWh, kuchepetsa ndi 84.5% |
Pamakampani onse, kugwiritsa ntchito dizilo kumachepetsedwa ndi 50% -90%.
Chitsanzo: Makina a dizilo osakanizidwa a solar hybrid microgrid pa ntchito ya migodi ku Zimbabwe atayamba kugwira ntchito, dizilo lapachaka zidatsika ndi 90%, kupulumutsa pafupifupi USD 6.948 miliyoni pamitengo yamafuta pachaka; pamgodi waku Chile, dizilo wosakanizidwa wa solar adadula dizilo kuchoka pa malita 980,000 kufika malita 468,000 mchaka chake choyamba, kutsika kwa 52.2%.
Kukhazikika Kwadongosolo: Momwe 99.9% Yoperekera Mphamvu Yopitilira Imakwaniritsidwa
Makampu a migodi salola kuzima kwa magetsi. Kudalirika kwa solar diesel hybrid microgrid kumadalira kamangidwe ka magawo asanu:
N+1 Zomangamanga Zosafunikira
Majenereta a dzuwa, osungira ndi dizilo amabwererana; mfundo imodzi yolephera sikumakhudza mphamvu zonse zamagetsi, ndi cholinga chodalirika cha 99.9%.
Intelligent EMS Energy Management
Kuyang'anira munthawi yeniyeni zotulutsa kwa sola, SOC yosungirako, mawonekedwe a jenereta ndi dizilo ndikutumiza zokha; imathandizira kuwunika kwakutali kudzera pa pulogalamu yam'manja/kompyuta ndi ntchito yosayang'aniridwa.
Kuthekera kwa Black Start
Pambuyo pozimitsa kwathunthu, imatha kuchira yokha popanda gwero lamphamvu lakunja.
UPS Uninterruptible Power Supply
Amapereka chitetezo chosasunthika kwa katundu wovuta kwambiri panthawi ya kusintha kwa magetsi, kuchotsa kutayika kwa deta ndi kutayika kwa zipangizo.
Kulekerera Kusungirako ndi Zida
Mabatire a Lithium iron phosphate (LiFePO4) okhala ndi moyo wozungulira wa 5,000-8,000 wozungulira komanso kulondola kwa SOC ≤3%; inverter bwino ≥95% ndi MPPT kutsatira bwino ≥99%; malo opangira magetsi a sola amavotera IP55, amatumizidwa kukana mphepo ya Level 9 pamene atumizidwa, ndipo amagwira ntchito kuchokera pa -20°C mpaka +50°C, kupangitsa kuti ikhale yoyenera kumadera ovuta kwambiri amigodi.
Chitsanzo chamakampani: solar diesel hybrid microgrid pa fakitale yopangira golide ku Western Australia inapeza kupezeka kwa 98.7% m'miyezi 18 yogwira ntchito; solar dizilo wosakanizidwa ma microgrids nthawi zambiri amafika podalilika wopitilira 99.9%.
Mafunso Ofunsidwa Kawirikawiri
Q1: Ndi mphamvu ziti zamakampu amigodi ndi solar dizilo wosakanizidwa microgrid yoyenera?
A: 20kW–200kW masiteshoni opangira magetsi adzuwa amachokera kumadera okhala polojekiti kupita kumigodi yayikulu; Kukonzekera kwa 100-500 kW kumagwiritsa ntchito migodi ikuluikulu yotseguka, yomwe imapanga pafupifupi 600,000 kWh pachaka ndikuchotsa matani pafupifupi 150 a dizilo.
Q2: Kodi kusintha kuchokera dizilo kupita yosungirako dzuwa Zimayambitsa kuzimitsa kwa zida?
A: Nthawi yathu yosinthira ndi ≤10 ms, yomwe ili pansi pazipata zomwe zida zimatha kuzindikira; UPS imathandiziranso katundu wovuta, kotero palibe kusokonezeka kwa mphamvu panthawi yosinthira.
Q3: Nanga bwanji masiku a mitambo kapena mvula motsatizana?
A: Kusungirako kumakhala kwakukulu kwa 3-7 motsatizana mitambo / mvula; pamene SOC yosungirako imagwera pansi pa 20% kapena nyengo yoipa, jenereta ya dizilo imangoyamba kuwonjezera mphamvu.
Q4: Kodi mungatsimikize ndalama zingati za dizilo?
A: Nthawi zambiri 50% -90%. Malo abwino kwambiri a Xuzhou Zm-Besta ndi 90.1%; kwenikweni zimatengera kuwala kwa dzuwa ndi katundu pamapindikira.
Q5: Zimatenga nthawi yayitali bwanji kuti mutumize chotengera mphamvu ya dzuwa station?
A: Zokonzedweratu ndi kutumizidwa ku fakitale, zikhoza kutumizidwa kuti zipange mphamvu mu ola limodzi la 1 mutangofika pamalopo. Mwachitsanzo, chidebe cha mapazi 20 chimatenga pafupifupi mphindi 80 kuti gulu la anthu 6 litumize mokwanira.
Q6: Kodi dongosololi likhoza kuyendetsedwa patali?
A: Inde. EMS yanzeru imathandizira kuyang'anira patali ndi kuwongolera kwa chipangizo / kuyimitsa kudzera pa pulogalamu yam'manja/kompyuta, ndikupangitsa kuti ntchito isasamalidwe ndi kukonza.
Ngati mukukonzekera njira yopangira magetsi osagwiritsa ntchito gridi kapena makina amagetsi akutali m'malo amigodi, malo omangira, kapena misasa yakutali, tikukulandirani kuti mulumikizane ndi Xuzhou Zm-Besta.
Dinani kuti mutumize kufunsa, ndipo tiloleni tipange njira yothetsera mphamvu pamsasa wanu ndi “Sola choyamba, dizilo monga chosungira chomaliza”.
