Dongosolo Losungira Mphamvu ya Batri (BESS) ndi dongosolo lalikulu la batri lozikidwa pa kulumikizana kwa gridi, lomwe limagwiritsidwa ntchito kusungira magetsi ndi mphamvu. Limaphatikiza mabatire angapo pamodzi kuti apange chipangizo chosungira mphamvu chophatikizana.
1. Selo ya Batri: Monga gawo la dongosolo la batri, imasintha mphamvu ya mankhwala kukhala mphamvu yamagetsi.
2. Batire Module: Yopangidwa ndi ma batire angapo otsatizana komanso olumikizidwa mofanana, imaphatikizapo Module Battery Management System (MBMS) yowunikira momwe ma batire amagwirira ntchito.
3. Batire Cluster: Imagwiritsidwa ntchito polumikiza ma module angapo olumikizidwa ndi Battery Protection Units (BPU), omwe amadziwikanso kuti batire cluster controller. Battery Management System (BMS) ya batire cluster imayang'anira magetsi, kutentha, ndi momwe mabatire amaliridwira pamene ikuwongolera nthawi yawo yolipirira ndi kutulutsa magetsi.
4. Chidebe Chosungiramo Mphamvu: Chingathe kunyamula magulu angapo a batri olumikizidwa mofanana ndipo chingakhale ndi zida zina zowonjezera zowongolera kapena kuwongolera chilengedwe cha mkati mwa chidebecho.
5. Dongosolo Losinthira Mphamvu (PCS): Mphamvu yolunjika (DC) yopangidwa ndi mabatire imasinthidwa kukhala mphamvu yosinthira (AC) kudzera mu PCS kapena ma inverter ozungulira awiri kuti itumizidwe ku gridi yamagetsi (malo kapena ogwiritsa ntchito). Ngati pakufunika, dongosololi lingathenso kutulutsa mphamvu kuchokera ku gridi kuti lizichaja mabatire.
Kodi mfundo yogwirira ntchito ya Battery Energy Storage Systems (BESS) ndi iti?
Mfundo yogwirira ntchito ya Battery Energy Storage System (BESS) imaphatikizapo njira zitatu: kuyatsa, kusunga, ndi kutulutsa mphamvu. Panthawi yoyatsa, BESS imasunga mphamvu zamagetsi mu batire kudzera mu gwero lamagetsi lakunja. Kugwiritsa ntchito kumatha kukhala mphamvu yamagetsi mwachindunji kapena mphamvu yosinthira, kutengera kapangidwe ka makina ndi zofunikira pakugwiritsa ntchito. Ngati pali mphamvu yokwanira yoperekedwa ndi gwero lamagetsi lakunja, BESS imasintha mphamvu yochulukirapo kukhala mphamvu ya mankhwala ndikuisunga m'mabatire otha kubwezeretsedwanso mkati. Panthawi yosungira, pamene palibe mphamvu yokwanira kapena yopanda mphamvu yakunja, BESS imasunga mphamvu yosungidwa yonse yodzazidwa ndipo imasunga kukhazikika kwake kuti igwiritsidwe ntchito mtsogolo. Panthawi yotulutsa mphamvu, pamene pakufunika kugwiritsa ntchito mphamvu yosungidwa, BESS imatulutsa mphamvu yoyenera malinga ndi kufunikira koyendetsa zida zosiyanasiyana, injini kapena mitundu ina ya katundu.
Kodi ubwino ndi zovuta zogwiritsa ntchito BESS ndi ziti?
BESS ikhoza kupereka maubwino ndi ntchito zosiyanasiyana ku makina amagetsi, monga:
1. Kulimbikitsa kuphatikiza mphamvu zongowonjezwdwa: BESS imatha kusunga mphamvu zongowonjezwdwa zochulukirapo panthawi yopanga mphamvu zambiri komanso yochepa, ndikuzitulutsa nthawi yopanga mphamvu zochepa komanso yofunika kwambiri. Izi zitha kuchepetsa kuchepa kwa mphepo, kusintha kuchuluka kwa momwe imagwiritsidwira ntchito, ndikuchotsa nthawi ndi kusiyana kwake.
2. Kukweza ubwino ndi kudalirika kwa mphamvu: BESS ikhoza kupereka yankho mwachangu komanso losinthasintha ku kusinthasintha kwa magetsi ndi ma frequency, ma harmonics, ndi mavuto ena a mphamvu. Ithanso kugwira ntchito ngati gwero lamagetsi lothandizira ndikuthandizira ntchito yoyambira yakuda panthawi ya gridi kapena pakagwa ngozi.
3. Kuchepetsa kufunikira kwakukulu: BESS imatha kuyitanitsa nthawi yomwe magetsi sagwiritsidwa ntchito kwambiri pamene mitengo yamagetsi ndi yotsika, komanso kutulutsa mphamvu nthawi yomwe mitengo yamagetsi ndi yokwera. Izi zitha kuchepetsa kufunikira kwakukulu, kuchepetsa ndalama zamagetsi, ndikuchedwetsa kufunikira kwa kukulitsa mphamvu zatsopano zopangira magetsi kapena kukweza magiya.
4. Kuchepetsa mpweya woipa wowononga chilengedwe: BESS ingachepetse kudalira kupanga mafuta ochokera ku zinthu zakale, makamaka nthawi yomwe zinthu zimafika pachimake, komanso kuwonjezera mphamvu zongowonjezwdwanso mu mphamvu zamagetsi. Izi zimathandiza kuchepetsa mpweya woipa wowononga chilengedwe komanso kuchepetsa zotsatira za kusintha kwa nyengo.
Komabe, BESS imakumananso ndi mavuto ena, monga:
1. Mtengo wokwera: Poyerekeza ndi magwero ena amagetsi, BESS ikadali yokwera mtengo, makamaka pankhani ya ndalama zogulira, ndalama zogwirira ntchito ndi kukonza, komanso ndalama zogulira moyo wonse. Mtengo wa BESS umadalira zinthu zambiri monga mtundu wa batri, kukula kwa makina, kugwiritsa ntchito, ndi momwe msika ulili. Pamene ukadaulo ukukulirakulira, mtengo wa BESS ukuyembekezeka kuchepa mtsogolo koma ukhoza kukhalabe cholepheretsa kugwiritsa ntchito magetsi ambiri.
2. Nkhani zachitetezo: BESS imaphatikizapo magetsi amphamvu, mphamvu yamagetsi yayikulu, ndi kutentha kwambiri komwe kungayambitse zoopsa monga ngozi zamoto, kuphulika, kugwedezeka kwa magetsi ndi zina zotero. BESS ilinso ndi zinthu zoopsa monga zitsulo, ma acid ndi ma electrolyte zomwe zingayambitse zoopsa zachilengedwe ndi thanzi ngati sizikusamalidwa bwino. Miyezo yolimba yachitetezo, malamulo ndi njira ndizofunikira kuti BESS igwire ntchito bwino komanso isamalidwe bwino.
5. Zotsatira za chilengedwe: BESS ikhoza kukhala ndi zotsatirapo zoipa pa chilengedwe kuphatikizapo kuchepa kwa zinthu, mavuto okhudza kugwiritsa ntchito nthaka, mavuto okhudza kugwiritsa ntchito madzi, komanso mavuto okhudza kuipitsidwa kwa nthaka. BESS imafuna zinthu zambiri zopangira monga lithiamu, cobalt, nickel, mkuwa ndi zina zotero, zomwe sizipezeka padziko lonse lapansi ndipo sizigawidwa mofanana. BESS imagwiritsanso ntchito madzi ndi nthaka popanga migodi, komanso kugwiritsa ntchito. BESS imapanga zinyalala ndi mpweya woipa m'moyo wake wonse zomwe zingakhudze ubwino wa nthaka m'madzi amlengalenga. Zotsatira za chilengedwe ziyenera kuganiziridwa mwa kugwiritsa ntchito njira zokhazikika kuti zichepetse zotsatira zake momwe zingathere.
Kodi ntchito zazikulu ndi momwe BESS imagwiritsidwira ntchito ndi ziti?
BESS imagwiritsidwa ntchito kwambiri m'mafakitale ndi ntchito zosiyanasiyana, monga kupanga magetsi, malo osungira mphamvu, mizere yotumizira ndi kugawa magetsi mumakina amagetsi, komanso makina amagetsi ndi magalimoto apamadzi mu gawo la mayendedwe. Imagwiritsidwanso ntchito mumakina osungira mphamvu zamabatire m'nyumba zogona ndi zamalonda. Makina awa amatha kukwaniritsa zosowa zosungira mphamvu zochulukirapo ndikupereka mphamvu zosungira kuti achepetse kudzaza kwa mizere yotumizira ndi kugawa magetsi pomwe akuletsa kudzaza kwa makina otumizira magetsi. BESS imagwira ntchito yofunika kwambiri mu ma grid ang'onoang'ono, omwe ndi maukonde amagetsi ogawidwa olumikizidwa ku grid yayikulu kapena ogwira ntchito pawokha. Ma grid ang'onoang'ono odziyimira pawokha omwe ali m'madera akutali amatha kudalira BESS kuphatikiza ndi magwero amagetsi obwezerezedwanso nthawi ndi nthawi kuti akwaniritse kupanga magetsi okhazikika pomwe akuthandiza kupewa ndalama zambiri zokhudzana ndi injini za dizilo ndi mavuto a kuipitsidwa kwa mpweya. BESS imabwera m'makulidwe osiyanasiyana komanso mawonekedwe, oyenera zida zazing'ono zapakhomo komanso makina akuluakulu ogwiritsira ntchito. Amatha kuyikidwa m'malo osiyanasiyana kuphatikiza nyumba, nyumba zamalonda, ndi malo osinthira magetsi. Kuphatikiza apo, amatha kukhala magwero amagetsi othandizira mwadzidzidzi panthawi ya mdima.
Kodi mitundu yosiyanasiyana ya mabatire omwe amagwiritsidwa ntchito mu BESS ndi iti?
1. Mabatire a lead-acid ndi mtundu wa batri womwe umagwiritsidwa ntchito kwambiri, wopangidwa ndi mbale za lead ndi sulfuric acid electrolyte. Amalemekezedwa kwambiri chifukwa cha mtengo wawo wotsika, ukadaulo wawo wokhwima, komanso moyo wawo wautali, makamaka m'malo monga mabatire oyambira, magwero amagetsi adzidzidzi, komanso malo osungira mphamvu ang'onoang'ono.
2. Mabatire a lithiamu-ion, omwe ndi amodzi mwa mabatire otchuka komanso apamwamba kwambiri, amakhala ndi ma electrode abwino ndi oipa opangidwa kuchokera ku chitsulo cha lithiamu kapena zinthu zophatikizika pamodzi ndi zosungunulira zachilengedwe. Ali ndi ubwino monga kuchuluka kwa mphamvu, kugwira ntchito bwino, komanso kuchepa kwa mphamvu zachilengedwe; amagwira ntchito yofunika kwambiri pazida zam'manja, magalimoto amagetsi, ndi ntchito zina zosungira mphamvu.
3. Mabatire oyenda ndi zida zosungira mphamvu zomwe zingadzazidwenso zomwe zimagwira ntchito pogwiritsa ntchito zinthu zamadzimadzi zomwe zimasungidwa m'matanki akunja. Makhalidwe awo ndi monga mphamvu yochepa koma kugwira ntchito bwino komanso kukhala ndi nthawi yayitali yogwira ntchito.
4. Kuwonjezera pa njira zomwe tatchulazi, palinso mitundu ina ya BESS yomwe ikupezeka kuti musankhe monga mabatire a sodium-sulfur, mabatire a nickel-cadmium, ndi ma super capacitor; iliyonse ili ndi makhalidwe osiyanasiyana komanso magwiridwe antchito oyenera zochitika zosiyanasiyana.
