Battery Energy Storage System (BESS) ndi njira yayikulu ya batri yotengera kulumikizidwa kwa gridi, yomwe imagwiritsidwa ntchito posungira magetsi ndi mphamvu. Zimaphatikiza mabatire angapo palimodzi kuti apange chipangizo chophatikizira chosungira mphamvu.
1. Battery Cell: Monga gawo la dongosolo la batri, limasintha mphamvu zamagetsi kukhala mphamvu zamagetsi.
2. Battery Module: Yopangidwa ndi ma cell angapo okhudzana ndi batri ogwirizana, imaphatikizapo Module Battery Management System (MBMS) kuti iwonetsere momwe ma cell a batri akuyendera.
3. Battery Cluster: Amagwiritsidwa ntchito kuti agwirizane ndi ma modules angapo okhudzana ndi mndandanda ndi Units Protection Units (BPU), yomwe imadziwikanso kuti wolamulira gulu la batri. Battery Management System (BMS) ya gulu la batire imayang'anira mphamvu yamagetsi, kutentha, ndi kuyitanitsa mabatire kwinaku akuwongolera kayendedwe kawo kacharging ndi kutulutsa.
4. Chitsulo Chosungira Mphamvu: Ikhoza kunyamula magulu angapo a batri ogwirizana omwe ali ofanana ndipo akhoza kukhala ndi zigawo zina zowonjezera kuti athe kuyang'anira kapena kuyang'anira chilengedwe cha mkati mwa chidebecho.
5. Power Conversion System (PCS): Mphamvu yachindunji (DC) yopangidwa ndi mabatire imasinthidwa kukhala alternating current (AC) kudzera pa PCS kapena bidirectional inverters kuti iperekedwe ku gridi yamagetsi (zithandizo kapena ogwiritsira ntchito mapeto). Pakafunika, dongosololi limathanso kutulutsa mphamvu kuchokera pagululi kuti lipereke mabatire.
Kodi mfundo yogwirira ntchito ya Battery Energy Storage Systems (BESS) ndi iti?
Mfundo yogwira ntchito ya Battery Energy Storage System (BESS) imaphatikizapo njira zitatu: kulipiritsa, kusunga, ndi kutulutsa. Panthawi yolipira, BESS imasunga mphamvu zamagetsi mu batri kudzera pa gwero lamphamvu lakunja. Kukhazikitsa kutha kukhala kwachindunji kapena kusinthasintha kwapano, kutengera kapangidwe ka makina ndi zofunikira pakugwiritsa ntchito. Pakakhala mphamvu yokwanira yoperekedwa ndi gwero lamphamvu lakunja, BESS imasintha mphamvu zochulukirapo kukhala mphamvu zamakemikolo ndikuzisunga m'mabatire owonjezeranso mu mawonekedwe osinthika mkati. Panthawi yosungira, pamene palibe chakudya chokwanira kapena palibe, BESS imakhalabe ndi mphamvu yosungidwa yosungidwa ndikusunga bata kuti igwiritsidwe ntchito mtsogolo. Pakutulutsa mphamvu, pakafunika kugwiritsa ntchito mphamvu zosungidwa, BESS imatulutsa mphamvu yoyenerera molingana ndi kufunikira koyendetsa zida zosiyanasiyana, mainjini kapena mitundu ina ya katundu.
Kodi maubwino ndi zovuta zotani pogwiritsa ntchito BESS?
BESS ikhoza kupereka maubwino ndi ntchito zosiyanasiyana pamakina amagetsi, monga:
1. Kupititsa patsogolo kuphatikizika kwa mphamvu zowonjezereka: BESS ikhoza kusunga mphamvu zowonjezereka zowonjezereka panthawi ya kukula kwakukulu ndi kufunikira kocheperako, ndikuzimasula panthawi yochepa komanso yofunidwa kwambiri. Izi zitha kuchepetsa kuchepa kwa mphepo, kupititsa patsogolo kagwiritsidwe ntchito kake, ndikuchotsa kusinthasintha kwake komanso kusinthasintha kwake.
2. Kupititsa patsogolo mphamvu ya mphamvu ndi kudalirika: BESS ikhoza kupereka yankho lachangu komanso losavuta kusinthasintha kwamagetsi ndi kusinthasintha kwafupipafupi, ma harmonics, ndi zina zamtundu wa mphamvu. Itha kukhalanso ngati gwero lamagetsi osunga zobwezeretsera ndikuthandizira ntchito yoyambira yakuda panthawi yamagetsi yamagetsi kapena pakagwa mwadzidzidzi.
3. Kuchepetsa kufunikira kwapamwamba: BESS ikhoza kulipira nthawi yomwe simunakhalepo pamene mitengo yamagetsi ili yotsika, ndikutulutsa nthawi yamtengo wapatali pamene mitengo ili yokwera. Izi zitha kuchepetsa kufunikira kwamphamvu, kutsika mtengo wamagetsi, ndikuchedwetsa kufunikira kwa kukulitsa mphamvu za m'badwo watsopano kapena kukweza kufalitsa.
4. Kuchepetsa mpweya wowonjezera kutentha: BESS ikhoza kuchepetsa kudalira mafuta opangira mafuta, makamaka panthawi yomwe imakhala yovuta kwambiri, pamene ikuwonjezera gawo la mphamvu zowonjezera pamagetsi. Izi zimathandiza kuchepetsa kutulutsa mpweya wowonjezera kutentha komanso kuchepetsa zotsatira za kusintha kwa nyengo.
Komabe, BESS imakumananso ndi zovuta zina, monga:
1. Mtengo wapamwamba: Poyerekeza ndi magetsi ena, BESS ikadali yokwera mtengo, makamaka ponena za ndalama zamtengo wapatali, ndalama zoyendetsera ntchito ndi kukonza, komanso ndalama zoyendetsera moyo. Mtengo wa BESS umatengera zinthu zambiri monga mtundu wa batri, kukula kwa dongosolo, kugwiritsa ntchito, komanso momwe msika ukuyendera. Ukadaulo ukakula ndikukulirakulira, mtengo wa BESS ukuyembekezeka kutsika mtsogolomo koma ungakhalebe cholepheretsa kutengera kufalikira.
2. Nkhani za chitetezo: BESS imaphatikizapo mphamvu yamagetsi, mphamvu yaikulu, ndi kutentha kwakukulu komwe kumayambitsa zoopsa zomwe zingatheke monga zoopsa zamoto, kuphulika, kugwedezeka kwa magetsi etc. ngati sichinasamalidwe kapena kutayidwa bwino. Miyezo yolimba yachitetezo, malamulo ndi njira zimafunikira pakuwonetsetsa kuti ntchito ndi kasamalidwe kotetezeka ka BESS.
5. Kukhudzidwa ndi chilengedwe: BESS ikhoza kukhala ndi zotsatira zoipa pa chilengedwe kuphatikizapo kuwonongeka kwa zinthu, kugwiritsa ntchito nthaka mavuto ogwiritsira ntchito madzi kuwononga zinyalala, ndi kuwononga chilengedwe. kusowa padziko lonse lapansi ndi kugawa kosagwirizana.BESS imadyanso madzi ndi malo poikapo migodi, ndipo operation.BESS imatulutsa zinyalala ndi utsi m'moyo wake wonse womwe ungathe. kukhudza ubwino wa nthaka ya madzi a mpweya. Kukhudzidwa kwa chilengedwe kuyenera kuganiziridwa potsatira njira zokhazikika zochepetsera zotsatira zake momwe zingathere.
Kodi ntchito zazikulu ndi zogwiritsa ntchito za BESS ndi ziti?
BESS imagwiritsidwa ntchito kwambiri m'mafakitale ndi ntchito zosiyanasiyana, monga kupanga magetsi, malo osungiramo mphamvu, mizere yotumizira ndi kugawa mumagetsi amagetsi, komanso magalimoto amagetsi ndi machitidwe apanyanja mu gawo la zoyendera. Amagwiritsidwanso ntchito m'makina osungira mphamvu za batri m'nyumba zogona komanso zamalonda. Machitidwewa amatha kukwaniritsa zosowa zosungirako za mphamvu zowonjezera ndikupereka mphamvu zosunga zobwezeretsera kuti achepetse kuchulukitsitsa pamizere yotumizira ndi kugawa kwinaku akuletsa kusokonekera mumayendedwe opatsirana. BESS imatenga gawo lofunikira mu ma gridi ang'onoang'ono, omwe amagawidwa ma netiweki amagetsi olumikizidwa ndi gridi yayikulu kapena akugwira ntchito palokha. Ma gridi ang'onoang'ono odziyimira pawokha omwe ali kumadera akumidzi amatha kudalira BESS kuphatikiza magwero amphamvu omwe angapitirireko pang'onopang'ono kuti akwaniritse kupanga magetsi okhazikika pomwe amathandizira kupewa kukwera mtengo komwe kumakhudzana ndi injini za dizilo komanso zovuta zakuwonongeka kwa mpweya. BESS imabwera mosiyanasiyana ndi masanjidwe, oyenera zida zazing'ono zapakhomo komanso zida zazikulu zothandizira. Zitha kukhazikitsidwa m'malo osiyanasiyana kuphatikiza nyumba, nyumba zamalonda, ndi masiteshoni. Kuphatikiza apo, amatha kukhala ngati magwero amagetsi osungira mwadzidzidzi panthawi yamagetsi.
Kodi mabatire amtundu wanji omwe amagwiritsidwa ntchito mu BESS ndi ati?
1. Mabatire a lead-acid ndi mtundu wa batire womwe umagwiritsidwa ntchito kwambiri, wokhala ndi mbale zamtovu ndi electrolyte ya sulfuric acid. Amayamikiridwa kwambiri chifukwa cha mtengo wawo wotsika, ukadaulo wokhwima, komanso moyo wautali, womwe umagwiritsidwa ntchito makamaka m'malo monga mabatire oyambira, magwero amagetsi adzidzidzi, komanso kusungirako mphamvu pang'ono.
2. Mabatire a lithiamu-ion, imodzi mwa mitundu yodziwika bwino komanso yapamwamba kwambiri ya mabatire, imakhala ndi ma electrode abwino ndi oipa opangidwa kuchokera ku lithiamu zitsulo kapena zipangizo zophatikizika pamodzi ndi zosungunulira organic. Iwo ali ndi ubwino monga mkulu kachulukidwe mphamvu, mkulu dzuwa, ndi otsika mphamvu zachilengedwe; imagwira ntchito yofunika kwambiri pazida zam'manja, magalimoto amagetsi, ndi zida zina zosungira mphamvu.
3. Mabatire akuyenda ndi zida zosungiramo mphamvu zomwe zimagwiranso ntchito pogwiritsa ntchito media zamadzimadzi zomwe zimasungidwa muakasinja akunja. Makhalidwe awo ndi otsika mphamvu kachulukidwe koma mkulu dzuwa ndi moyo wautali utumiki.
4. Kuphatikiza pa zosankha zomwe tazitchula pamwambapa, palinso mitundu ina ya BESS yomwe ingasankhidwe monga mabatire a sodium-sulfure, nickel-cadmium mabatire, ndi ma capacitor apamwamba; chilichonse chimakhala ndi mawonekedwe osiyanasiyana komanso magwiridwe antchito oyenera pazosintha zosiyanasiyana.
