Battery Energy Storage System (BESS) yakakura-chiyero bhatiri system yakavakirwa pane grid yekubatanidza, inoshandiswa kuchengetedza magetsi uye simba. Iyo inosanganisa mabhatiri akawanda pamwechete kuti iite yakabatanidzwa yekuchengetedza simba mudziyo.
1. Battery Cell: Sechikamu chebhatiri system, inoshandura simba remakemikari kuita simba remagetsi.
2. Battery Module: Yakagadzirwa nemhando dzakawanda uye parallel yakabatana masero ebheteri, inosanganisira Module Battery Management System (MBMS) kutarisa kushanda kwemasero ebheteri.
3. Battery Cluster: Inoshandiswa kugadzirisa akawanda akatevedzana-akabatanidzwa modules uye Battery Protection Units (BPU), inozivikanwawo sebhatiri cluster controller. Iyo Battery Management System (BMS) yebhatiri cluster monitors voltage, tembiricha, uye kuchaja mamiriro emabhatiri uku ichidzora kutenderera kwavo nekuchaja.
4. Energy Storage Container: Inogona kutakura akawanda parallel-yakabatana mabhatiri masumbu uye anogona kunge akashongedzerwa nezvimwe zvikamu zvekuwedzera zvekutarisira kana kutonga mukati memukati memudziyo.
5. Power Conversion System (PCS): Iyo yakananga ikozvino (DC) inogadzirwa nemabhatiri inoshandurwa kuva alternating current (AC) kuburikidza nePCS kana bidirectional inverters yekutumira kune grid magetsi (zvishandiso kana vashandi vekupedzisira). Kana zvichidikanwa, iyi sisitimu inogona zvakare kuburitsa simba kubva kune grid kubhadharisa mabhatiri.
Ndeipi musimboti wekushanda weBattery Energy Storage Systems (BESS)?
Iyo yekushanda musimboti weBattery Energy Storage System (BESS) inonyanya kusanganisira matatu maitiro: kuchaja, kuchengeta, uye kuburitsa. Munguva yekuchaja, BESS inochengeta simba remagetsi mubhatiri kuburikidza nekunze kwesimba sosi. Kuitwa kwacho kunogona kuve kwakananga ikozvino kana kuchinjisa ikozvino, zvichienderana nedhizaini yehurongwa uye zvinodiwa zvekushandisa. Kana paine simba rakakwana rinopihwa nekunze kwesimba sosi, BESS inoshandura yakawandisa simba kuita kemikari simba uye inoichengeta mumabhatiri anochajiswa mune inovandudzwa fomu mukati. Munguva yekuchengetedza, kana pasina kukwana kana pasina kunze kwekunze kunowanikwa, BESS inochengetedza zvakakwana zvakabhadharwa simba rakachengetwa uye inochengetedza kugadzikana kwayo kushandiswa kwemangwana. Munguva yekuburitsa, kana paine kudikanwa kwekushandisa simba rakachengetwa, BESS inoburitsa huwandu hwakakodzera hwesimba zvichienderana nekudiwa kwekutyaira kwakasiyana michina, injini kana mamwe maitiro ekutakura.
Ndeapi mabhenefiti uye matambudziko ekushandisa BESS?
BESS inogona kupa akasiyana mabhenefiti uye masevhisi kusimba remagetsi, senge:
1. Kuwedzera kubatanidzwa kwesimba rinodzokororwa: BESS inogona kuchengetedza yakawandisa simba rinogona kudzokororwa munguva dzechizvarwa chepamusoro uye kudiwa kwakaderera, uye kuisunungura panguva yezera rakaderera uye kudiwa kukuru. Izvi zvinogona kuderedza kuderedzwa kwemhepo, kunatsiridza chiyero chekushandiswa kwayo, uye kubvisa kupindirana kwayo uye kusiyanisa.
2. Kuvandudza kunaka kwesimba uye kuvimbika: BESS inogona kupa mhinduro inokurumidza uye inoshanduka kune voltage uye frequency kushanduka, harmonics, uye mamwe magetsi emhando nyaya. Iyo inogona zvakare kushanda senge backup simba sosi uye inotsigira dema kutanga basa panguva yekudzima grid kana emergency.
3. Kuderedza kudiwa kwepamusoro-soro: BESS inogona kubhadharisa panguva ye-off-peak maawa apo magetsi emitengo yakaderera, uye kubudiswa panguva dzepamusoro apo mitengo yakakwirira. Izvi zvinogona kuderedza kudiwa kwepamusoro, kudzikisa mitengo yemagetsi, uye kunonoka kudiwa kwekuwedzera kwechizvarwa chitsva kana kukwidziridzwa kwekutapurirana.
4. Kudzikisa kuburitswa kwegasi regreenhouse: BESS inogona kuderedza kuvimba nefossil-based generation, kunyanya panguva dzepamusoro-soro, uku ichiwedzera chikamu chesimba rinowanikwazve mumusanganiswa wemagetsi. Izvi zvinobatsira kuderedza kuburitswa kwegasi regreenhouse uye kudzikisira kukanganisa kwekushanduka kwemamiriro ekunze.
Nekudaro, BESS inotarisanawo nemamwe matambudziko, akadai se:
1. Mutengo wepamusoro: Kana uchienzaniswa nemamwe magetsi, BESS ichiri kudhura, kunyanya maererano nemutengo wemari, mari yekushanda nekugadzirisa, uye mari yehupenyu. Mutengo weBESS unoenderana nezvakawanda zvinhu zvakaita serudzi rwebhatiri, saizi yehurongwa, application, uye mamiriro emusika. Sezvo tekinoroji ichikura uye kukwira kumusoro, mutengo weBESS unotarisirwa kudzikira mune ramangwana asi ungangove uchiri chipingamupinyi pakupararira kutorwa.
2. Nyaya dzekuchengetedza: BESS inosanganisira high voltage, yakakura ikozvino, uye kupisa kwepamusoro izvo zvinokonzera njodzi dzinogona kuitika dzakadai senjodzi dzemoto, kuputika, magetsi emagetsi etc. BESS inewo zvinhu zvinokuvadza zvakadai sesimbi, acids uye electrolytes zvinogona kukonzera njodzi dzezvakatipoteredza uye utano. kana isina kubatwa kana kuraswa zvakanaka. Yakasimba kuchengetedza zviyero, mirau uye maitiro anodiwa kuti ave nechokwadi chekushanda kwakachengeteka uye manejimendi eBESS.
5. Kukanganisa kwezvakatipoteredza: BESS inogona kuva nemigumisiro yakaipa pane zvakatipoteredza kusanganisira kupera kwezviwanikwa, nyaya dzekushandiswa kwevhu matambudziko ekushandiswa kwemvura kuparara kwemarara, uye kusvibiswa kwekusvibiswa. kushomeka pasi rose nekugovewa kusina kuenzana. BESS inoshandisawo mvura uye ivhu pakugadzira migodhi, uye kushanda. BESS inounza marara uye kuburitsa mukati mehupenyu hwayo hwose hunogona. kukanganisa kunaka kwevhu remvura yemhepo.Kukanganisa kwezvakatipoteredza kunoda kutariswa nekutora miitiro inoenderera mberi kuderedza mhedzisiro yazvo zvakanyanya sezvinobvira.
Ndeapi makuru ekushandisa uye makesi ekushandisa eBESS?
BESS inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana uye mashandisirwo, akadai sekugadzira magetsi, masimba ekuchengetedza magetsi, mitsara yekutapurirana uye yekugovera musimba remagetsi, pamwe nemotokari yemagetsi uye marine masisitimu muchikamu chekutakura. Inoshandiswawo mumabhatiri simba rekuchengetedza masisitimu ekugara uye ekutengesa zvivakwa. Aya masisitimu anogona kusangana nezvinodiwa zvekuchengetera zvesimba rakawanda uye nekupa backup kugona kudzikisa kuwanda pakutakura uye kugovera mitsara uku ichidzivirira kusangana muhurongwa hwekutapurirana. BESS inoita basa rakakosha mumamicro grids, ayo akagovaniswa magetsi emagetsi akabatana kune iyo huru grid kana kushanda yakazvimiririra. Yakazvimiririra madiki magidhi ari munzvimbo dziri kure anogona kuvimba neBESS yakasanganiswa nepakati penguva inodzokororwa magetsi masosi kuti iwane yakagadzikana kugadzirwa kwemagetsi uku ichibatsira kudzivirira mutengo wakakwira une chekuita neinjini dzedhiziri uye nyaya dzekusvibiswa kwemhepo. BESS inouya muhukuru hwakasiyana uye zvigadziriso, inokodzera zvese zvidiki-zvidiki zvemumba zvishandiso uye mahombe ekushandisa masisitimu. Dzinogona kuiswa munzvimbo dzakasiyana dzinosanganisira dzimba, zvivakwa zvekutengesa, uye zviteshi. Pamusoro pezvo, ivo vanogona kushanda sechimbichimbi backup magetsi masosi panguva yekudzima.
Ndeapi marudzi akasiyana emabhatiri anoshandiswa muBESS?
1. Lead-asidhi mabhatiri ndiyo inonyanya kushandiswa mhando yebhatiri, inosanganisira mahwendefa emutobvu uye sulfuric acid electrolyte. Vanoremekedzwa zvakanyanya nekuda kwemutengo wavo wakaderera, tekinoroji yakakura, uye hupenyu hurefu, inonyanya kushandiswa munzvimbo dzakadai sekutanga mabhatiri, masosi emagetsi ekukurumidzira, uye diki-mwero simba rekuchengetedza.
2. Lithium-ion mabhatiri, imwe yemhando dzakakurumbira uye dzakakwirira dzemabhatiri, dzinosanganisira dzakanaka uye dzisina kunaka electrode dzakagadzirwa kubva ku lithiamu metal kana composite zvinhu pamwe chete ne organic solvents. Ivo vane zvakanakira senge yakakwira simba density, kushanda zvakanaka kwepamusoro, uye kuderera kwemamiriro ekunze; kutamba basa rakakosha mune nharembozha, mota dzemagetsi, uye mamwe magetsi ekuchengetedza magetsi.
3. Mabhatiri anoyerera anogona kuchajwazve magetsi ekuchengetedza magetsi ayo anoshanda achishandisa liquid media yakachengetwa mumatangi ekunze. Zvimiro zvavo zvinosanganisira kuderera kwesimba remagetsi asi kushanda kwakanyanya uye hupenyu hurefu hwebasa.
4. Pamusoro pezvisarudzo izvi zvataurwa pamusoro apa, kunewo mamwe marudzi eBESS aripo pakusarudzwa akadai sesodium-sarufa mabhatiri, nickel-cadmium mabhatiri, uye super capacitors; imwe neimwe iine hunhu hwakasiyana uye kuita kwakakodzera kune akasiyana siyana.
