Sisitimu Yekuchengetera Simba reBattery (BESS) sisitimu yemabhatiri yakakura yakavakirwa pakubatanidza magetsi, inoshandiswa kuchengetedza magetsi nesimba. Inobatanidza mabhatiri akawanda pamwe chete kuti igadzire mudziyo wekuchengetera simba wakabatana.
1. Sero reBhatiri: Sechikamu chehurongwa hwebhatiri, rinoshandura simba remakemikari kuita simba remagetsi.
2. Bhatiri Module: Yakagadzirwa nemasero emabhatiri akawanda akatevedzana uye akabatana zvakafanana, inosanganisira Module Battery Management System (MBMS) yekutarisa mashandiro emasero ebhatiri.
3. Bhatiri Cluster: Inoshandiswa kugamuchira mamodule akawanda akabatana neBattery Protection Units (BPU), inozivikanwawo seBattery cluster controller. Bhatiri Management System (BMS) yebhatiri cluster inotarisa voltage, tembiricha, uye mamiriro ekuchaja emabhatiri uku ichidzora machajiro avo ekuchaja nekuburitsa magetsi.
4. Chigadziko Chekuchengetera Simba: Chinogona kutakura mabheteri akawanda akabatana pamwe chete uye chinogona kunge chakashongedzerwa nezvimwe zvinhu zvekutarisira kana kudzora mamiriro emukati mechigadziko.
5. Sisitimu Yekushandura Simba (PCS): Simba remagetsi rinogadzirwa nemabhatiri rinoshandurwa kuita simba remagetsi rinochinja-chinja (AC) kuburikidza nePCS kana ma inverter maviri kuti riendeswe kugrid remagetsi (nzvimbo kana vashandisi). Kana zvichidikanwa, sisitimu iyi inogonawo kubvisa simba kubva pagrid kuti ichajise mabhatiri.
Ndeipi musimboti wekushanda kweBattery Energy Storage Systems (BESS)?
Nheyo yekushanda kweBattery Energy Storage System (BESS) inonyanya kusanganisira maitiro matatu: kuchaja, kuchengetedza, uye kuburitsa simba. Munguva yekuchaja, BESS inochengeta simba remagetsi mubhatiri kuburikidza nemagetsi ekunze. Kushandiswa kwacho kunogona kuva current yakananga kana alternating current, zvichienderana nekugadzirwa kwesisitimu uye zvinodiwa pakushandisa. Kana paine simba rakakwana rinopihwa nemagetsi ekunze, BESS inoshandura simba rakawandisa kuita simba remakemikari uye inorichengeta mumabhatiri anogona kuchajwazve muchimiro chinogona kudzokororwa mukati. Munguva yekuchengetedza, kana pasina kukwana kana kusavapo kwekunze, BESS inochengetedza simba rakachengetwa rakachajwa rakazara uye inochengetedza kugadzikana kwayo kuti ishandiswe mune ramangwana. Munguva yekuburitsa simba, kana paine chikonzero chekushandisa simba rakachengetwa, BESS inoburitsa simba rakakodzera zvichienderana nekudiwa kwekutyaira zvishandiso zvakasiyana-siyana, mainjini kana mamwe marudzi emitoro.
Ndezvipi zvakanakira nematambudziko ekushandisa BESS?
BESS inogona kupa mabhenefiti akasiyana-siyana uye mabasa kune sisitimu yemagetsi, akadai se:
1. Kuvandudza kubatanidzwa kwesimba rinogona kuvandudzwa: BESS inogona kuchengetedza simba rakawandisa rinogona kuvandudzwa munguva dzekugadzirwa kwakawanda uye kudiwa kushoma, uye kuiburitsa munguva dzekugadzirwa kushoma uye kudiwa kwakanyanya. Izvi zvinogona kuderedza kuderedzwa kwemhepo, kuvandudza mwero wekushandiswa kwayo, uye kubvisa nguva yayo yekupindira nekusiyana-siyana.
2. Kuvandudza kunaka kwemagetsi uye kuvimbika kwawo: BESS inogona kupa mhinduro inokurumidza uye inochinjika kumamiriro emagetsi nekuchinja-chinja kwema frequency, harmonics, nezvimwe zvinetso zvemhando yemagetsi. Inogona zvakare kushanda senzvimbo yekuchengetedza magetsi uye kutsigira black start function panguva yekudzima kwegrid kana emergency.
3. Kuderedza kudiwa kwemagetsi zvakanyanya: BESS inogona kuchaja panguva dzisiri dzenguva dzemagetsi zvakanyanya apo mitengo yemagetsi yakaderera, uye inoburitsa magetsi zvakanyanya panguva dzenguva dzemagetsi zvakanyanya apo mitengo yakakwira. Izvi zvinogona kuderedza kudiwa kwemagetsi zvakanyanya, kuderedza mitengo yemagetsi, uye kunonotsa kudiwa kwekuwedzera simba rekugadzira magetsi matsva kana kusimudzira magiya emagetsi.
4. Kuderedza kuburitswa kwemhepo inopisa: BESS inogona kuderedza kuvimba nekugadzirwa kwemafuta ekare, kunyanya munguva dzekupisa, ukuwo ichiwedzera simba rinogona kuvandudzwa mumagetsi. Izvi zvinobatsira kuderedza kuburitswa kwemhepo inopisa uye kuderedza migumisiro yekuchinja kwemamiriro ekunze.
Zvisinei, BESS inosanganawo nematambudziko, akadai se:
1. Mutengo wakakwira: Kana tichienzanisa nezvimwe zvinopa simba, BESS ichiri kudhura zvakanyanya, kunyanya kana tichitarisa mari yekushandisa, mari yekushandisa nekugadzirisa, uye mari yehupenyu hwese. Mutengo weBESS unoenderana nezvinhu zvakawanda zvakaita semhando yebhatiri, saizi yesystem, mashandisirwo, uye mamiriro emusika. Sezvo tekinoroji ichikura uye ichikwira, mutengo weBESS unotarisirwa kudzikira mune ramangwana asi uchiri chipingamupinyi pakushandiswa kwakapararira.
2. Nyaya dzekuchengetedza: BESS inosanganisira magetsi akawanda, magetsi makuru, uye tembiricha yepamusoro izvo zvinogona kukonzera njodzi dzakadai semoto, kuputika, kuvhunduka kwemagetsi nezvimwewo. BESS inewo zvinhu zvine njodzi zvakaita sesimbi, maasidhi nemaelectrolyte zvinogona kukonzera njodzi dzezvakatipoteredza nedzehutano kana zvikasabatwa kana kuraswa zvakanaka. Mitemo yakasimba yekuchengetedza, mitemo uye maitiro zvinodiwa kuti BESS ishande zvakanaka uye itarisirwe zvakanaka.
5. Kukanganiswa kwezvakatipoteredza: BESS inogona kukanganisa nharaunda zvakanyanya kusanganisira kupera kwezviwanikwa, matambudziko ekushandiswa kwevhu, matambudziko ekushandiswa kwemvura, kuburitsa marara, uye kusvibiswa kwemhepo. BESS inoda huwandu hwakawanda hwezvinhu zvakaita se lithium, cobalt, nickel, mhangura nezvimwewo, izvo zvisingawanikwe pasi rose uye zvisina kuenzana pakupararira. BESS inoshandisawo mvura nenyika pakugadzira migodhi, uye kushanda kwayo. BESS inogadzira marara uye kuburitsa utsi muhupenyu hwayo hwese izvo zvinogona kukanganisa kunaka kwevhu remvura yemhepo. Kukanganiswa kwezvakatipoteredza kunofanirwa kufungwa nezvako nekushandisa nzira dzinogara kwenguva refu kuti dzideredze migumisiro yadzo zvakanyanya sezvinobvira.
Ndezvipi zvinhu zvikuru zvinoshandiswa uye mashandisirwo eBESS?
BESS inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana uye mashandisirwo, akadai sekugadzira magetsi, nzvimbo dzekuchengetera simba, tambo dzekutumira nekuparadzira mumagetsi, pamwe chete nemotokari dzemagetsi nedzemugungwa muchikamu chekufambisa. Inoshandiswawo mumasisitimu ekuchengetedza simba remabhatiri ezvivakwa zvekugara nezvemabhizinesi. Masisitimu aya anogona kusangana nezvinodiwa zvekuchengetedza simba rakawanda uye kupa simba rekuchengetedza kuderedza kuwanda kwetambo dzekutumira nekuparadzira uku achidzivirira kuwanda kwesimba mumagetsi. BESS inoita basa rakakosha mumagrid madiki, ayo ari manetwork emagetsi akagoverwa akabatana negrid huru kana kushanda ega. Magrid madiki akazvimiririra ari munzvimbo dziri kure anogona kuvimba neBESS pamwe chete nemagetsi anodzokororwa nguva nenguva kuti awane magetsi akasimba uku achibatsira kudzivirira mitengo yakakwira inokonzerwa neinjini dzedhiziri nematambudziko ekusvibiswa kwemhepo. BESS inouya muhukuru hwakasiyana uye magadzirirwo, akakodzera midziyo midiki yemumba uye masisitimu makuru ekushandisa. Anogona kuiswa munzvimbo dzakasiyana kusanganisira dzimba, zvivakwa zvemabhizinesi, uye zviteshi zvemagetsi. Uyezve, anogona kushanda semagetsi ekuchengetedza ekukurumidza panguva yekudzima kwemagetsi.
Ndeapi marudzi akasiyana emabhatiri anoshandiswa muBESS?
1. Mabhatiri e lead-acid ndiwo anonyanya kushandiswa, anosanganisira maplate e lead ne sulfuric acid electrolyte. Anoremekedzwa zvikuru nekuda kwemutengo wakaderera, tekinoroji yakakura, uye hupenyu hwawo hurefu, anonyanya kushandiswa munzvimbo dzakadai semabhatiri ekutanga, matsime emagetsi ekukurumidza, uye nzvimbo diki dzekuchengetedza simba.
2. Mabhatiri eLithium-ion, rimwe remhando dzakakurumbira uye dzepamusoro dzemabhatiri, ane maelectrode akanaka neasina kunaka akagadzirwa nesimbi yelithium kana zvinhu zvakasanganiswa pamwe chete nezvinonyungudutsa zveorganic. Ane zvakanakira zvakaita sekuwanda kwesimba, kushanda zvakanaka, uye kusakanganisa nharaunda; achiita basa rakakosha mumidziyo inotakurika, mota dzemagetsi, uye mamwe mashandisirwo ekuchengetedza simba.
3. Mabhatiri anoyerera zvinhu zvinochengeterwa simba zvinochajwazve zvinoshanda uchishandisa mvura inochengetwa mumatangi ekunze. Hunhu hwazvo hunosanganisira simba shoma asi kushanda zvakanaka uye hupenyu hurefu hwebasa.
4. Kuwedzera kune idzi sarudzo dzataurwa pamusoro apa, kunewo mamwe marudzi eBESS anowanikwa ekusarudza akadai semabhatiri e sodium-sulfur, mabhatiri e nickel-cadmium, uye ma super capacitor; rimwe nerimwe rine hunhu hwakasiyana uye mashandiro akakodzera mamiriro akasiyana.
