Indlela yokulungelelanisa amandla e-inverter nomthamo webhetri
Umthamo webhetri namandla e-inverter zichaza iinxalenye ezimbini ezahlukeneyo zecandelo lokugcina amandla. Umthamo webhetri, olinganiswa ngeekhilowathi-ziyure, unquma ukuba icandelo lingagcina amandla angakanani na. Amandla e-inverter, alinganiswa ngeekhilowathi, unquma ukuba icandelo lingayitshaja okanye liyikhuphe ngokukhawuleza kangakanani na loo mandla.
Ibhetri ye-215 kWh ayifuni isayizi enye engaguqukiyo ye-inverter. Isilinganiselo esichanekileyo se-PCS sixhomekeke kumthwalo wendawo, ixesha lokukhupha umbane, ixesha lokutshaja, umda wangoku webhetri kunye neemeko zokusebenza.
Qala ngamandla okukhulula afunekayo.
Sebenzisa idatha yemithwalo elinganisiweyo ukubala amandla ombane ekufuneka ibhetri iwanikezele. Kwiprojekthi yokunciphisa umthwalo ophezulu, susa imfuno yegridi evumelekileyo kumthwalo ophezulu olinganisiweyo wendawo:
Amandla okukhulula afunekayo = Eyona mfuno iphezulu yendawo − Imfuno ejoliswe kuyo yegridi
Ifektri enenani eliphezulu lama-250 kW kunye nesilindelo se-150 kW kwigridi ifuna malunga ne-100 kW yamandla okukhupha ebhetri. Iinjineli kufuneka zikwajonge umbane wokuqalisa i-motor, amanyathelo omthwalo kunye nohlobo lokumelana nokugqithisa kwe-PCS. Ezi ziganeko zexesha elifutshane zinokugqitha isidingo samandla aqhubekayo.
Kwi-applyikeshini zokuxhasa, balisa amandla adityanisiweyo emithwalo ebalulekileyo ekufuneka ihlale isebenza ngexesha lokunqamka kombane. Musa ukukhetha ubungakanani be-PCS ngokusekelwe kwisixa somthwalo wonke oqhagamshelweyo ukuba inkqubo yokuxhasa iza kunika amandla kuphela kwizixhobo ezikhethiweyo.
Jonga umda wamandla ebhetri
Ibhetri kunye ne-BMS zibeka elona mandla aphezulu anokutsalwa yi-PCS. Qinisekisa umsinga wokutshaja oqhubekayo ovumelekileyo, umsinga wokukhupha oqhubekayo kunye nomsinga ophezulu wexesha elifutshane.
Ukuhlolwa kwamandla e-DC okugcinayo kusebenzisa:
Umda wamandla ebhetri ye-DC = I-voltage esebenzayo encinci × I-current eqhubekayo ephezulu ÷ 1,000
Ungakwazi nokuqikelela umda wamandla ebhetri ngokwe-C-rate yayo:
Umda wamandla ebhetri = Umthamo webhetri × Ireyithi ye-C evumelekileyo
Umzekelo, ibhetri ye-215 kWh esebenza nge-0.5C ixhasa malunga ne-107.5 kW phambi kokuba kufikelelwe kwimida yevoltheji, i-current, iqondo lobushushu kunye ne-BMS. Sebenzisa i-datasheet yemodeli ethile kunye nezicwangciso ze-BMS kwisibalo sokugqibela.
Bala amandla okutshaja afunekayo
Ixesha elikhoyo lokutshaja lisenokufuna i-PCS enkulu. Yahlula amandla ekufuneka abuyiswe ngexesha elikhoyo lokutshaja:
Amandla okutshaja afunekayo = Amandla adityaniswayo / ixesha lokutshaja

Q4: Kutheni ukusebenza kakuhle kwe-inverter kubalulekile kwisixokelelwano sokugcina amandla?
Ukusebenza kakuhle kwe-inverter kunempembelelo ngqo kwisixa samandla asetyenzisekayo anikezelwa kwimithwalo. I-inverter esebenza kakuhle ngakumbi inciphisa ilahleko yamandla ngexesha loguqulo, iphucula ukusebenza kwenkqubo iyonke, kwaye yehlisa iindleko zexesha elide zokusebenza kokugcinwa kwamandla.
Q5: Ingaba iibhetri ze-hybrid ze-solid-state zingasebenza na neenkqubo zamandla elanga?
Ewe. Iibhetri ze-hybrid ze-solid-state zihlala zidityaniswa neenkqubo ze-photovoltaic (PV). Xa zidityaniswe ne-inverter efanelekileyo yokugcina amandla, ziyakwazi ukugcina amandla elanga agqithisileyo emini zize zibonelele ngombane ebusuku okanye xa kukho ukunqamka kombane.
Q6: Zeziphi izicelo ezifaneleke kakhulu kwiinkqubo ze-inverter yebhetri ye-solid-state?
Iinkqubo ze-inverter yebhetri ze-solid-state zisetyenziswa kakhulu kwi: Ugcino lwamandla elanga ezindlini Amandla orhwebo nawoshishino (C&I) ugcino Iimayikrogridi Amandla okugcina e-Telecom Iziko ledatha Izikhululo zokutshaja iimoto zombane Iiprojekthi zamandla ahlaziyekayo ezingumthombo wamandla
Q7: Zeziphi iiprotocol zonxibelelwano ekufuneka i-inverter yokugcina amandla iyixhase?
Ii-inverters zale mihla zokugcina amandla kufuneka zixhase iiprotocol zonxibelelwano ezikumgangatho weshishini ezifana ne-CAN kunye ne-RS485. Ezi protocol zenza ukuba kubekho unxibelelwano lwangoko nangoko ne-BMS kunye ne-EMS, nto leyo ephucula ukhuseleko lwebhetri, ukubeka iliso, kunye nokusebenza kakuhle kwenkqubo iyonke.
Q8: Ibhetri ye-hybrid solid-state iphucula njani ukusebenza kokugcinwa kwamandla?
Iibhetri ze-hybrid ze-solid-state zidibanisa iingenelo zokhuseleko ze-electrolytes eziqinileyo kunye neenzuzo zokusebenza kobuchwepheshe beebhetri ze-lithium eziqhelekileyo. Ngokwesiqhelo zibonelela ngozinzo oluphezulu lobushushu, ubomi obude bokuphindaphinda ukusetyenziswa, ukhuseleko oluphuculweyo, kunye nobuninzi bamandla obuphezulu xa zithelekiswa neebhetri zemveli ze-lithium-ion.
Q9: Yintoni ekufuneka ndiyithathele ingqalelo xa ndikhetha i-inverter yokugcina amandla yezorhwebo?
Iinkalo eziphambili ziquka: Amandla omveliso alinganisiweyo Umthamo wokufaka we-PV Inani lezixhobo zokulandelela ze-MPPT Ukusebenza kakuhle kuguqulo Umgangatho wokukhuselwa kwe-IP Ukuhambelana kwegrid Unxibelelwano lwe-BMS ne-EMS Isantya sokutshintshela esisisigcina Uluhlu lobushushu bokusebenza Ukukhetha i-inverter efanelekileyo kubaluleke kakhulu ekwandiseni ukuthembeka kweprojekthi kunye nembuyekezo kutyalo-mali.
Q10: Kutheni ukhetha iMegSolid kwizisombululo zeebhetri ze-solid-state kunye nee-inverter?
IMegSolid ibonelela ngezisombululo ezidibeneyo zokugcina amandla ezidibanisa iibhetri ezixubekileyo ze-solid-state, ii-inverters zokugcina amandla, iiNkqubo zokuLawula iiBhetri (i-BMS), kunye neeNkqubo zokuLawula aMandla (i-EMS). Le ndlela idibeneyo inceda abathengi ukuba bafumane ukusebenza kakuhle okuphezulu, ukhuseleko oluphuculweyo, ubomi obude bebhetri, kunye neendleko eziphantsi zesistim iyonke kwizicelo zasekhaya, zorhwebo, nezoshishino.
