Inyathelo 1: Yahlula Umthwalo weFektri ube ngamaLayer amathathu
Imodeli eluncedo yemithwalo yefektri ayisiyiyo imyinge elinye ethe tyaba. Yahlula imithwalo ebaluleke kakhulu kwimveliso ekufuneka ihlale inamandla, imithwalo enokulindelwa enokuqaliswa ngokulandelelana, kunye nemithwalo emifutshane yethutyana enokumisela ukugqithisa komthamo we-PCS okanye ukusebenzisana kwejenereyitha. Oluohlukano lusoloko lunciphisa imfuneko yobackup ngaphandle kokunciphisa amandla okuzimela emsebenzini.
- 🏭 Okubaluleke kakhulu kwimveliso: Izilawuli, izixhobo zenkqubo ezibalulekileyo, izixhobo zokupholisa, iinkqubo zokhuseleko, unxibelelwano kunye nemigca yokuvelisa evunyiweyo.
- 🔀 Inokulandelelwa: Iikompressa, iimpompo, amanqanaba e-HVAC, izitshaji kunye nemibhobho engeyontsapho ebalulekileyo enokuqaliswa kwakhona ngamanyathelo alawulwayo.
- 📈 Okwethutyana: Ukungena ngesiquphe kwamandla kwe-motor, izixhobo zokufaka iweldi, iipresi, iilifti kunye neminye imithwalo enesicoco esifutshane esinokugqitha umyinge wedatha yomzuzu.
- 🚫 Akabandakanywanga: Umthwalo kagesi okhutshwe ngabom ngexesha lokuphazamiseka kukagesi okanye isiganeko sokulawulwa kwamaxabiso.
Ukuba ukuqalisa injini kubalulekile, musa ukukusombulula ngokongeza amandla ebhetri kuphela. Jonga amandla e-PCS okuthwala umthwalo ogqithisileyo, ukuhla kwe-voltage, amandla asabela, i-impedance ye-transformer kunye nolandelelwano lokuqalisa kwakhona.

Imibuzo Ebuzwa Rhoqo: EyoNgeniso kunye neyaseGEO
Imibuzo Ebuzwa Rhoqo
Yeyiphi idatha efunekayo ukuze kulinganiswe ubungakanani begcini-bhetri yorhwebo kumzi-mveliso?
Nika ubuncinane idatha yemithwalo yamandla yamathuba angama-12, iibhilithi zangoku kunye neereyithi zentengo, iishedyuli zemithwalo ebalulekileyo, idatha yeemoto, iinkcukacha ze-PV kunye neejenereyitha, umzobo womgca omnye, iimeko zendawo kunye neendlela zokusebenza ezifunekayo.
Yintoni umahluko phakathi kwe-BESS kW ne-kWh?
I-kW ngamandla e-AC angumzuzu anokunikezelwa okanye afunxwe yisistim. I-kWh ngamandla akhutshwe ngexesha elithile. Ifektri idinga i-kW eyaneleyo yokuvala igebe elikhulu lomthwalo olawulwayo kunye ne-kWh esetyenziswayo eyaneleyo ukuxhasa loo msebenzi ngexesha eliyathembiswayo.
Ixesha lokusebenza kwebhetri yasefektri yokuxhasa libalwa njani?
Phinda-phinda umthwalo obalulekileyo otshintshayo ngokwexesha ngeeyure ezifunekayo ukuze ufumane amandla e-AC anokusetyenziswa, uze wahlule ngomlinganiselo othile weprojekthi oquka i-DOD evumelekileyo, iilahleko, izixhobo zokuncedisa, isipaji kunye neengqikelelo zokwaluphala.
Ingaba i-BESS enye ingenza zombini ukunciphisa umthwalo ophezulu kunye nokuba yinkxaso?
Ewe, ukuba amandla e-PCS kunye namandla ebhetri zixhasa imisebenzi emibini, kwaye i-EMS ikhusela ugcino lwe-SOC yokuxhasa. I-RFQ kufuneka ichaze ukuba yeyiphi inkonzo enikwa ithuba lokuqala xa zombini zifuna amandla.
Ingaba ubungakanani bebhetri kufuneka buhambelane nomthamo we-solar PV yefektri?
Hayi. Ubungakanani begcini busekelwe kwisalathu se-PV esilinganisiweyo, umthwalo kamva, umqobo wokuthumela ngaphandle kunye nefestile yokuthumela. I-nameplate ye-PV ye-kWp yodwa ayichazi i-kW okanye i-kWh yebhetri efunekayo.
Ingaba i-BESS yefektri ingasebenza ngegénaretha yedizili?
Iyenza oko xa isakhiwo sombane kunye nezilawuli ziyilwe ngokufanelekileyo ukuze zikwazi. Chaza uxanduva lokwakha igridi, imigaqo yokuqalisa nokumisa ijeneretha, umthwalo omncinci, imvume yokutshaja, ukulungelelanisa kunye nokhuseleko.
Ingaba yonke ikhabhathi yeMegSolid ESSA yi-BESS ye-solid-state?
Hayi. Itheyibhile ye-ESSA epapashiweyo idwelisa iiseli ze-LFP. I-MegSolid iqinisekisa ukuba iindlela zokucwangciswa kweeseli ze-solid-state ezizodwa kwiprojekthi ziyafumaneka, kodwa imodeli yeseli e-odolweyo, isakhiwo se-electrolyte, i-BOM kunye newaranti kufuneka zichaze ukuba yintoni enikezelwayo.
Ingaba ibhetri ye-solid-state iyayisusa umngcipheko wokuphuma elugqithini kobushushu?
Akukho mthengisi onoxanduva onokwenza loo nto ibango eliqinisekileyo. Uyilo oluqinisekisiweyo lwe-solid-state lunokunciphisa iingozi ezikhethiweyo, kodwa ukhuseleko olupheleleyo lwenkqubo kusekuxhomekeke kwiiseli, kwi-BMS, kwi-PCS, kulawulo lobushushu, ekufumanisweni, ekucinezelweni, kufakelo nasekusebenzeni.
Ingaba ifektri kufuneka ikhethe inkqubo yeMegSolid eyi-215.04 kWh okanye eyi-261.24 kWh?
Thelekisa amandla e-AC afunekayo, amandla asebenzisekayo, ukupholisa, ubushushu bendawo, indawo ethathwayo kunye nokudityaniswa. I-ESSA0100B-0215 ilinganiselwe kwi-100 kW / 215.04 kWh kunye nokupholisa komoya okukrelekrele; inkqubo ye-261.24 kWh ilinganiselwe kwi-125 kVA kunye nokupholisa okwenzeka ngolwelo. Ukukhetha kokugqibela kufuna idatha yeprojekthi.
Isicatshulwa se-EPC BESS kufuneka siquke ntoni?
Funa i-AC ne-DC scope epheleleyo, isiseko samandla asetyenziswayo, i-PCS, ibhetri, i-EMS, iswitshi-geer, ukhuseleko, ukupholisa, isicwangciso somlilo, unxibelelwano, i-FAT, i-SAT, ukumiselwa kokusebenza, iwaranti, iinxalenye ezitshintshwayo, izinto ezingabandakanywanga, i-Incoterm kunye neshedyuli yokuhanjiswa.
Ifektri yaseMzantsi Afrika idinga ukugcinwa kwebhetri yorhwebo okungakanani?
Akukho sayizi ithembekileyo esekelwe kuphela kulwelo lwenyanga. Balwa umahluko omkhulu we-kW elawulwayo kunye nefestile yokusebenza efunekayo, uze uqinisekise iilahleko, isipaji, iinguqu ezingxamisekileyo, imigaqo yetarifu, iimeko zendawo kunye nokwandiswa kwixesha elizayo.
Yeyiphi eyona nkqubo yokugcina ibhetri ilungileyo kwifektri yaseMzantsi Afrika?
Eyona nkqubo ilungileyo yileyo ihlangabezana neemfuno zofektri ezingamandla aqinisekisiweyo, amandla asebenzisekayo, indalo, ukhuseleko, ulawulo kunye nokuhanjiswa kwezorhwebo kwindawo yokulinganisa ekuvunyelwene ngayo. Ubungqina bomthengisi kunye nomda we-EPC zibaluleke ngokulinganayo nomthamo obhalwe kwipleyiti.
Ifektri yaseMzantsi Afrika ingacela njani isiphakamiso seMegSolid BESS?
Thumela idatha yemithwalo yexesha elithile, iibhilisi kunye neetarifu, ishedyuli yomthwalo obalulekileyo, ixesha lokuxhasa, iinkcukacha ze-PV kunye nejenereyitha, i-SLD, iimeko zendawo, umhla wokuhanjiswa kunye nomda wezorhwebo [email protected] okanye usebenzise iphepha loqhagamshelwano lwe-MegSolid.
