A bhatiri simba rekuchengetedza sisitimu, inowanzo zivikanwa seBESS, inoshandisa mabhangi emabhatiri anochajiswa kuchengetedza yakawandisa magetsi kubva kune grid kana masosi anogoneka kushandiswa gare gare.Sezvo simba rinovandudzwa uye smart grid tekinoroji inofambira mberi, BESS masisitimu ari kuita basa rinowedzera kukosha mukudzikamisa magetsi uye nekuwedzera kukosha kwegirinhi simba.Saka masisitimu aya anoshanda sei chaizvo?
Danho 1: Bhangi Bhangi
Hwaro hwechero BESS ndiyo simba rekuchengetedza svikiro - mabhatiri.Mamodules ebhatiri akawanda kana "masero" anobatanidzwa pamwe chete kuti aite "bhatiri bhangi" rinopa inodiwa kuchengetedza.Masero anonyanya kushandiswa i-lithium-ion nekuda kwehuwandu hwesimba rayo, hupenyu hurefu uye kugona kuchaja nekukurumidza.Mamwe makemikoro akaita selead-acid uye mabhatiri ekuyerera anoshandiswawo mune mamwe maapplication.
Danho rechipiri: Simba rekushandura System
Bhangi rebhatiri rinobatanidza kune grid yemagetsi kuburikidza nemagetsi ekushandura system kana PCS.Iyo PCS ine masimba emagetsi emagetsi senge inverter, converter, uye mafirita anobvumira simba kuyerera munzira mbiri pakati pebhatiri negridi.Iyo inverter inoshandura yakananga ikozvino (DC) kubva mubhatiri kuita inochinjika ikozvino (AC) inoshandiswa negridi, uye inoshandura inoita reverse kuchaja bhatiri.
Nhanho 3: Battery Management System
Iyo bhatiri manejimendi system, kana BMS, inotarisisa uye inodzora yega yega bhatiri sero mukati mebhatiri bhangi.Iyo BMS inoyera maseru, inogadzirisa voltage uye yazvino panguva yekuchaja uye kuburitsa, uye inodzivirira kubva pakukuvadzwa kubva pakuchaja, overcurrents kana kudzika kwakadzika.Iyo inotarisisa mapikicha akakosha senge voltage, yazvino uye tembiricha kuti ikwidze kushanda kwebhatiri uye hupenyu hurefu.
Nhanho 4: Kutonhodza System
Chimiro chekutonhora chinobvisa kupisa kwakanyanya kubva kumabhatiri panguva yekushanda.Izvi zvakakosha kuchengetedza maseru mukati meiyo yakakwana tembiricha renji uye nekuwedzera hupenyu hwekutenderera.Mhando dzakawanda dzekutonhodza dzinoshandiswa kutonhora kwemvura (nekutenderedza chinotonhodza kuburikidza nendiro dzinenge dzasangana nemabhatiri) uye kutonhodza mhepo (uchishandisa mafeni kumanikidza mweya kuburikidza nemabhatiri akavharirwa).
Danho rechishanu: Kushanda
Munguva dzekuderera kwemagetsi kudiwa kana yakakwira kugadzirwa kwesimba, iyo BESS inotora simba rakawandisa kuburikidza neiyo simba rekushandura system uye inoichengeta mubhangi rebhatiri.Kana kudiwa kwakakwira kana kudzoreredzwa kusipo, simba rakachengetwa rinodzoserwa kune grid kuburikidza neinverter.Izvi zvinobvumira iyo BESS ku "nguva-kuchinja" inopindirana inogona kuvandudzwa simba, kudzikamisa grid frequency uye voltage, uye nekupa backup simba panguva yekudzima.
Iyo bhatiri manejimendi sisitimu inotarisisa mamiriro ekuchajiswa kwesero rega rega uye inodzora mwero wekuchajisa uye kubuda kudzivirira kuwandisa, kupisa uye kudzika kwakadzika kwemabhatiri - kuwedzera hupenyu hwavo hunogona kushandiswa.Uye iyo yekutonhodza sisitimu inoshanda kuchengetedza tembiricha yebhatiri mukati menzvimbo yakachengeteka yekushandisa.
Muchidimbu, bhatiri rekuchengetedza simba system rinokwevera mabhatiri, masimba emagetsi emagetsi, hungwaru kutonga uye kudziya kwemafuta pamwe chete mufashoni yakabatanidzwa kuchengetedza yakawandisa magetsi uye yekuburitsa simba painodiwa.Izvi zvinobvumira tekinoroji yeBESS kuti iwedzere kukosha kwezviwanikwa zvesimba rinowanikwazve, kuita kuti magidhi emagetsi ashande uye arambe akagadzikana, uye kutsigira shanduko kune yakaderera-kabhoni simba remangwana.
Nekusimuka kwesimba remagetsi rinogoneka senge solar nemhepo simba, hombe mabhatiri ekuchengetedza simba masisitimu (BESS) ari kuita basa rinowedzera rakakosha mukudzikamisa magetsi emagetsi.Iyo bhatiri simba rekuchengetedza sisitimu inoshandisa mabhatiri anochajwa kuchengetedza magetsi akawandisa kubva kune grid kana kubva kune anovandudzwa uye kudzosera iwo simba parinodiwa.BESS tekinoroji inobatsira kukwirisa mashandisirwo esimba rinodzokororwa uye inonatsiridza kuvimbika kwegedhi, kushanda nesimba uye kusimba.
BESS inowanzo umbwa nezvikamu zvakawanda:
1) Mabhangi ebhatiri akagadzirwa neakawanda bhatiri module kana maseru kuti ape inodiwa simba rekuchengetedza simba.Lithium-ion mabhatiri anonyanya kushandiswa nekuda kwekuwanda kwesimba rawo, hupenyu hurefu uye kugona kuchaja nekukurumidza.Mamwe makemistri akaita selead-asidhi uye mabhatiri ekuyerera anoshandiswawo.
2) Simba rekushandura sisitimu (PCS) inobatanidza bhatiri bhangi kune grid yemagetsi.Iyo PCS ine inverter, inoshandura uye imwe midziyo yekudzora inobvumira simba kuyerera munzira mbiri pakati pebhatiri negridi.
3) Bhatiri manejimendi system (BMS) inotarisisa uye inodzora mamiriro uye kuita kweiyo yega bhatiri maseru.Iyo BMS inoyera maseru, inodzivirira kubva pakukuvadzwa kubva pakuchajisa kana kudzika kwakadzika, uye inotarisisa paramita sevoltage, ikozvino uye tembiricha.
4) Inotonhorera system inobvisa kupisa kwakanyanya kubva kumabhatiri.Liquid kana air-based kutonhora inoshandiswa kuchengetedza mabhatiri mukati meiyo yakakwana yekushanda tembiricha renji uye kuwedzera hupenyu.
5) Dzimba kana mudziyo unodzivirira uye unochengetedza iyo yese bhatiri system.Mabhatiri ekunze akavharirwa anofanirwa kusapindirana nemamiriro ekunze uye anokwanisa kushingirira tembiricha yakanyanyisa.
Mabasa makuru eBESS ndeaya:
• Bvisa simba rakawandisa kubva pagridi munguva dzekuda kwakaderera uye risunungure kana kudiwa kuri pamusoro.Izvi zvinobatsira kudzikamisa voltage uye frequency fluctuations.
• Chengeta simba rinofambiswazve kubva kunzvimbo dzakaita se solar PV nemapurazi emhepo anobuda zvakasiyana-siyana uye nguva nenguva, woendesa magetsi aya kana zuva risingapenye kana mhepo isiri kuvhuvhuta.Iyi nguva-inoshandura simba rinodzokororwa kusvika parinenge richinyanya kudiwa.
• Ipa simba rekuchengetedza panguva yekukanganisa kwegridi kana kudzima kuchengetedza zvakakosha zvivakwa zvinoshanda, mungave muchitsuwa kana grid-yakasungwa modhi.
• Tora chikamu mukupindura kwezvinodiwa uye zvirongwa zvebasa rekuwedzera nekukwidza simba kubuda kumusoro kana pasi pazvinodiwa, kupa kudzora frequency uye mamwe masevhisi egridi.
Mukupedzisa, sezvo simba rinovandudzwa richiramba richikura sechikamu chemazana emagetsi emagetsi pasi rese, mabhatiri makuru ekuchengetedza simba masisitimu achaita basa rinokosha mukuita kuti simba rakachena riya rivimbike uye riwanikwe nguva dzese.BESS tekinoroji ichabatsira kuwedzera kukosha kwezvinovandudzwa, kudzikamisa magidhi emagetsi uye kutsigira shanduko kuenda kune yakagadzikana, yakaderera-kabhoni simba remangwana.
