Njengengcali ephezulu kwiizihlanganisi zePV zokugcina inverters, I-Amass igcina inolwazi ngemarike kunye neemfuno zabathengi, kwaye ngokuqhubekayo isomeleza uphando lwemveliso kunye nophuhliso kunye nokwenziwa kwezinto ezintsha zobuchwepheshe. Ukuphucula ngokuqhubekayo inqanaba lenkonzo, ukubonelela abathengi ngokufanelekileyo, ngokukhuselekileyo, izixazululo zokudibanisa i-lithium-ion ezenziwe ngokwezifiso, kwishishini Siye sadunyiswa kwishishini.
Uxwebhu lwamva nje olunobunzima obunzima “Isaziso sokuKhuthaza amaShishini okuVeliswa koMbane waMandla aHlaziywayo ukuba akhe okanye aThenge iSakhono sokuNyusa uBume beGridi” sifuna ukwandiswa komlinganiselo wodityaniso lwegridi yokuvelisa amandla ahlaziyiweyo.
Nangona kungekho gama lithe ngqo logcino lwamandla, kodwa imarike kudala ithatha ugcino lwamandla njengento elungele ngokuthe ngqo.
Ngenxa yeemeko zendalo eziguquguqukayo zokukhanya kunye nomoya, okubangelwa amandla aphumayo angazinzanga, i-photovoltaic kunye namandla omoya akakwazi ukuhlala ehlangabezana neemfuno zamandla egridi, oko kukuthi, ukukhanya okushiywe kunye nomoya. Le yinkcitho eneneni. Ukuba la mandla achithwayo anokugcinwa, ke iindleko zokuvelisa amandla ahlaziyiweyo ziya kuqhubeka zihla. Kwaye esi sizathu sokuba kutheni ukuqhuma kwenkunzi yokugcina amandla.
Emva kokucacisa umkhombandlela jikelele, kubaluleke kakhulu ukujonga icandelo elinamandla anamandla okuqhuma okusisiseko.
Ukuba silandela le khrayitheriya, ke i-inverter sisandla sokukhetha imbewu.
Isizathu soku akunzima ukusiqonda. Kwinkqubo ye-PV, i-inverter idlala umsebenzi obalulekileyo njengokuguqulwa kwe-AC / DC, ulawulo lwamandla, kunye nokutshintshwa kwe-parallel / off-grid. Kwaye kwi-inverter, iinxalenye zayo ezincedisayo kwi-inverter isinxibelelanisi somgangatho womsebenzi nazo kufuneka zithathelwe ingqalelo.
Ngaphandle koncedo lwenkqubo yokugcina amandla, umbane owenziwe yi-PV uqhagamshelwe ngokuthe ngqo kwigridi nge-inverter. Ngokugcinwa kwamandla, umbane owenziwe yi-PV kuqala ugcinwe kwinkqubo yokugcina nge-inverter, kwaye emva koko umbane uxhunywe kwigridi nge-inverter. Nangona kukho enye ijika, kodwa iya kukwazi ukugcina umbane ochithekileyo (ukukhanya okushiywe), ngaloo ndlela ukwandisa iiyure zokusetyenziswa kwePV.
Ukukhula kwemfuno yee-inverters akunakuphepheka. Ngokoqikelelo lophando olunxulumeneyo, i-inverter yokugcina amandla e-PV yehlabathi jikelele ehambelana nomthamo ofakiweyo ukuya kuthi ga kwi-104GW ngo-2025, ngelixa i-global efakwe kwi-2020 yayiyi-5.3GW kuphela. oko kukuthi, amaxesha angama-20 kwiminyaka emi-5, kunye nesantya sokukhula esihlanganisiweyo sonyaka esingaphezulu kwama-80%.
Mhlawumbi abanye abantu baya kuthi, amandla amatsha onke amacandelo, imfuno iyanda, ngoko kuphi na ukugqithisa kwe-inverter?
Ukubeka ngokulula, ii-inverters zinengqiqo esebenzisekayo. Ubomi besityalo esikhulu sePV esibekwe emhlabeni buhlala bumalunga nama-20 eminyaka. I-inverter inqunyelwe ngamacandelo angaphakathi ekhompyutheni (i-IGBT, i-capacitors, i-inductors, njl.), ubomi benkonzo ngokuqhelekileyo abukho ngaphezu kweminyaka eyi-10. Ngamanye amazwi, isityalo samandla sePV
Ngamanye amazwi, isityalo sePV sidinga ubuncinci ii-inverters ezi-2 ebomini baso. Oku kubangela ukuba imfuno yokuguqula i-inverter izuze kungekuphela nje kwi-PV eyongezelelweyo, kodwa nakwi-stock. Ukunyuka kwemfuno ephantsi komsinga kudla ngokukhokelela ekunyukeni kwamaxabiso kwiimveliso ezinyukayo. Kuphela, inqaku elikhulu lomdla kwishishini le-inverter alikho ukunyuka kwexabiso, kodwa ipateni yoshishino kwicala lokubonelela. Isizathu sokuba ungalindelanga ukunyuka kwamaxabiso, kuba ii-inverters zinemiqobo yobugcisa yomibini, kodwa kunye nokupela ixabiso eliphantsi. Kwii-inverters ze-photovoltaic, umzekelo, i-inverter ye-1 exhunywe kwiimodyuli ze-photovoltaic ezili-12, ii-inverters kanye nje ingxaki, inkqubo yonke iya kuba ikhubazekile. Ugxininiso kukhuseleko, ukwenza ii-inverters zokuqala zenziwe eJamani. Nangona kunjalo, ngokubhekiselele kuyo yonke i-PV ye-industry chain chain, i-inverter iyona nto iphantsi yotyalo-mali, eyona nto i-asethi-ukukhanya kwekhonkco, kwaye oku kunika i-ambush elandelayo yexabiso eliphantsi.
I-inverter edityaniswe kwiimodyuli ezingaphezu kweshumi elinesibini zeemodyuli ze-photovoltaic, apho i-photovoltaic inverter iiterminals ze-DC ziyimfuneko, ngexesha elifanayo njengeendawo eziphambili zokudibanisa, kanye nomgangatho weengxaki zayo, kodwa kulula kakhulu ukukhokelela kukukhubazeka yonke inkqubo yokugcina amandla!
Abavelisi basekhaya kamva batyhoboza ngefestile yobugcisa, baza bakhupha umoya womsebenzi omkhulu, bakhawuleza basasaza umthamo wemveliso (ukusebenza kwe-asethi ye-asethi yeshishini, ukwandiswa kwamandla kuyakhawuleza), ngomgangatho olungileyo kunye neemveliso zexabiso eliphantsi, ukubamba isabelo semarike. ngexesha elifanayo, kodwa kunye ne-inverter kwinkqubo ye-photovoltaic.Ixabiso elipheleleyo lobunini ukuya ngaphantsi kwe-10%. Abavelisi basekhaya bathengisa iimveliso zaphesheya, eziphakathi kunye nexabiso leyunithi yexabiso leyunithi ye-yuan / W kunye ne-0.5 yuan / W, esezantsi kakhulu kunamashishini aphesheya kwe-0.57 yuan / W kunye ne-0.78 yuan / W ixabiso lokuthengisa.
Ukongeza ekunyukeni kwamaxabiso akulunganga kwipateni yeshishini, kuya kubakho umngcipheko wokuwa phakathi kwabathengi. Kule mihla, eyona nto imbi kakhulu kwikhonkco leshishini le-PV yiseli esezantsi kunye nabavelisi bemodyuli. Umlambo ophakamileyo ozama ukunyusa amaxabiso, baya kubambisana kunye nesando ngubani - ukunyuka kwexabiso kodwa kwakujoliswe kwi-silicon, iglasi ye-photovoltaic ngumzekelo. Njengengcali kwindleko-esebenzayoizixhumi zokugcina amandla, I-Amass ithatha indlela yophuhliso oluhlangeneyo lwabaxumi abaninzi, oluqinisekisa umgangatho weemveliso kunye nokunciphisa iindleko ngexesha elifanayo, kwaye igcina iindleko kubathengi abaninzi. Imeko engcono kakhulu yimeko yokuphumelela. Kuphela imeko yokuphumelela inokuqinisekisa uphuhliso oluzinzileyo. Ngale ndlela, kubonakala ngathi iphethini elungileyo yoshishino yinkuku ebeka amaqanda egolide kwi-inverter industry.
