Makina osungira mphamvu ya batire, omwe amadziwika kuti BESS, amagwiritsa ntchito mabanki a mabatire omwe amatha kuchangidwanso kuti asunge magetsi ochulukirapo kuchokera pagululi kapena magwero ongowonjezedwanso kuti agwiritsidwe ntchito mtsogolo.Pamene ukadaulo wamagetsi ongowonjezedwanso komanso luso la grid likupita patsogolo, makina a BESS akugwira ntchito yofunika kwambiri pakukhazikitsa mphamvu zamagetsi ndikukweza mtengo wamagetsi obiriwira.Ndiye kodi machitidwewa amagwira ntchito bwanji?
Gawo 1: Battery Bank
Maziko a BESS iliyonse ndi njira yosungiramo mphamvu - mabatire.Ma module angapo a batri kapena "ma cell" amalumikizidwa pamodzi kuti apange "banki ya batri" yomwe imapereka mphamvu yosungira yofunikira.Maselo omwe amagwiritsidwa ntchito kwambiri ndi lithiamu-ion chifukwa cha kuchuluka kwa mphamvu zawo, moyo wautali komanso kuthamanga mwachangu.Ma chemistry ena monga lead-acid ndi mabatire othamanga amagwiritsidwanso ntchito pazinthu zina.
Gawo 2: Mphamvu kutembenuka System
Banki ya batri imalumikizana ndi gridi yamagetsi kudzera pa makina osinthira mphamvu kapena PCS.PCS imakhala ndi zida zamagetsi zamagetsi monga inverter, converter, ndi zosefera zomwe zimalola mphamvu kuyenda mbali zonse ziwiri pakati pa batri ndi grid.Inverter imatembenuza Direct current (DC) kuchokera ku batire kupita ku alternating current (AC) yomwe gridi imagwiritsa ntchito, ndipo chosinthiracho chimasinthanso kuti azilipira batire.
Gawo 3: Battery Management System
Dongosolo loyang'anira batire, kapena BMS, limayang'anira ndikuwongolera batire iliyonse mkati mwa banki ya batri.BMS imayang'anira ma cell, imayang'anira ma voliyumu ndi apano panthawi yamalipiro ndi kutulutsa, ndikuteteza ku zowonongeka kuchokera pakuchulukirachulukira, ma overcurrents kapena kutulutsa kwambiri.Imayang'anira magawo ofunikira monga ma voltage, apano ndi kutentha kuti akwaniritse magwiridwe antchito a batri komanso moyo wautali.
Khwerero 4: Dongosolo Lozizira
Dongosolo loziziritsa limachotsa kutentha kwakukulu kuchokera ku mabatire panthawi yogwira ntchito.Izi ndizofunikira kuti ma cell azikhala mkati mwa kutentha kwabwino komanso kukulitsa moyo wozungulira.Mitundu yodziwika bwino ya kuziziritsa yomwe imagwiritsidwa ntchito ndi kuziziritsa kwamadzi (pozungulira zoziziritsa kukhosi kudzera m'mbale zomwe zalumikizana ndi mabatire) ndi kuziziritsa mpweya (kugwiritsa ntchito mafani kukakamiza mpweya kudzera m'mipanda ya batri).
Gawo 5: Opaleshoni
Nthawi yamagetsi otsika kwambiri kapena kupanga mphamvu zowonjezereka, BESS imatenga mphamvu zochulukirapo kudzera pamakina osinthira mphamvu ndikuzisunga mu banki ya batri.Zofuna zikachuluka kapena zowonjezera sizikupezeka, mphamvu yosungidwa imatulutsidwa ku gridi kudzera mu inverter.Izi zimalola BESS "kusintha nthawi" mphamvu zongowonjezera pang'ono, kukhazikika ma frequency a gridi ndi ma voliyumu, ndikupereka mphamvu zosunga zobwezeretsera pakatha.
Dongosolo la kasamalidwe ka batri limayang'anira momwe ma cell amawonongera ndikuwongolera kuchuluka kwa mtengo ndi kutulutsa kuti ateteze kuchulukira, kutentha kwambiri komanso kutulutsa kwakuya kwa mabatire - kukulitsa moyo wawo wogwiritsiridwa ntchito.Ndipo dongosolo lozizira limagwira ntchito kuti kutentha kwa batire kukhale kotetezeka.
Mwachidule, makina osungira mphamvu a batri amawonjezera mabatire, zida zamagetsi zamagetsi, zowongolera mwanzeru ndi kasamalidwe ka matenthedwe palimodzi mwanjira yophatikizika kuti asunge magetsi ochulukirapo ndikutulutsa mphamvu pakufunika.Izi zimalola ukadaulo wa BESS kukulitsa mtengo wamagetsi ongowonjezwdwa, kupanga ma gridi amagetsi kukhala abwino komanso osasunthika, ndikuthandizira kusintha kwa tsogolo lamphamvu la carbon low.
Ndi kukwera kwa mphamvu zongowonjezwdwanso monga mphamvu ya dzuwa ndi mphepo, makina akuluakulu osungira mphamvu za batire (BESS) akugwira ntchito yofunika kwambiri pakukhazikitsa ma gridi amagetsi.Makina osungira mphamvu ya batri amagwiritsa ntchito mabatire otha kuchangidwanso kuti asunge magetsi ochulukirapo kuchokera pagululi kapena kuchokera kumagetsi ongowonjezwdwa ndikubweza mphamvuyo ikafunika.Ukadaulo wa BESS umathandizira kukulitsa kugwiritsa ntchito mphamvu zongowonjezera pang'onopang'ono ndikuwongolera kudalirika kwa gridi, kuchita bwino komanso kukhazikika.
BESS nthawi zambiri imakhala ndi zigawo zingapo:
1) Mabanki a batri opangidwa ndi ma module angapo a batri kapena ma cell kuti apereke mphamvu yosungira mphamvu.Mabatire a lithiamu-ion amagwiritsidwa ntchito kwambiri chifukwa cha kuchuluka kwa mphamvu zawo, moyo wautali komanso kuthamanga kwachangu.Ma chemistry ena monga lead-acid ndi mabatire othamanga amagwiritsidwanso ntchito.
2) Mphamvu yosinthira mphamvu (PCS) yomwe imalumikiza banki ya batri ku gridi yamagetsi.PCS imakhala ndi inverter, converter ndi zida zina zowongolera zomwe zimalola mphamvu kuyenda mbali zonse pakati pa batri ndi grid.
3) Battery management system (BMS) yomwe imayang'anira ndikuwongolera momwe ma cell a batri amagwirira ntchito.BMS imayang'anira ma cell, imateteza ku kuwonongeka kwa kuchulukirachulukira kapena kutulutsa kwambiri, ndikuwunika magawo ngati ma voltage, apano ndi kutentha.
4) Dongosolo lozizira lomwe limachotsa kutentha kwakukulu kumabatire.Kuziziritsa kwamadzi kapena mpweya kumagwiritsidwa ntchito kusunga mabatire mkati mwa kutentha kwake koyenera komanso kukulitsa moyo wautali.
5) Nyumba kapena chidebe chomwe chimateteza ndikuteteza dongosolo lonse la batri.Malo otsekera mabatire akunja ayenera kukhala osagwirizana ndi nyengo ndipo amatha kupirira kutentha kwambiri.
Ntchito zazikulu za BESS ndi:
• Tengani mphamvu zochulukirapo mu gridi panthawi yomwe kufunikira kocheperako ndikumasula pamene kufunikira kuli kwakukulu.Izi zimathandiza kukhazikika kwamagetsi ndi kusinthasintha kwafupipafupi.
• Sungani mphamvu zongowonjezedwanso kuchokera kumagwero monga ma solar PV ndi mafamu amphepo omwe amakhala ndi mphamvu zosinthika komanso zapakatikati, kenaka perekani mphamvu zomwe zasungidwa kudzuwa sikukuwomba kapena mphepo sikuomba.Nthawi imeneyi imasamutsa mphamvu zongowonjezwdwa kukhala pamene ikufunika kwambiri.
• Perekani mphamvu zosunga zobwezeretsera panthawi yomwe gridi yawonongeka kapena kuzimitsidwa kuti zikhazikitso zofunikira zigwire ntchito, kaya pazilumba kapena pagulu.
• Kutenga nawo mbali pazofunikira ndi ntchito zina zothandizira pokweza mphamvu zamagetsi m'mwamba kapena pansi pakufunika, ndikuwongolera pafupipafupi ndi ntchito zina za gridi.
Pomaliza, mphamvu zongowonjezedwanso zikupitilira kukula ngati kuchuluka kwa ma gridi padziko lonse lapansi, makina akuluakulu osungira mphamvu za batire atenga gawo lofunika kwambiri kuti mphamvu zoyerazo zikhale zodalirika komanso kupezeka nthawi yonseyi.Ukadaulo wa BESS uthandizira kukulitsa mtengo wa zongowonjezera, kukhazikika kwa ma gridi amagetsi ndikuthandizira kusintha kwa tsogolo lokhazikika, lotsika kwambiri la carbon.
