Njengenxalenye engundoqo yeukuveliswa kwamandla e-photovoltaickunye neenkqubo zokugcina amandla, ii-inverters zidumile.Abantu abaninzi babona ukuba banegama elifanayo kunye nentsimi yesenzo kwaye bacinga ukuba luhlobo olufanayo lwemveliso, kodwa oku akunjalo.
Ifoto ii-voltaics kunye nee-inverters zokugcina amandla azikho kuphela "amaqabane angcono", kodwa ziyahluka kwizicelo eziphathekayo ezifana nemisebenzi, izinga lokusetyenziswa, kunye nengeniso.
Inverter yokugcina amandla
I-Converter yokugcina amandla (i-PCS), eyaziwa ngokuba yi-"bidirectional energy storage inverter", iyona nxalenye ephambili eqaphela ukuhamba kweendlela ezimbini zamandla ombane phakathi kwenkqubo yokugcina amandla kunye negridi yamandla.Isetyenziselwa ukulawula inkqubo yokutshaja kunye nokukhupha ibhetri kunye nokwenza i-AC kunye ne-DC switching.Guqula.Inokubonelela ngokuthe ngqo amandla kwimithwalo ye-AC xa kungekho grid yamandla.
1. Imigaqo esisiseko yokusebenza
Ngokweemeko zesicelo kunye nomthamo wabaguquli bokugcina amandla, abaguquli bokugcina amandla banokwahlulwa babe yi-photovoltaic ene-hybrid converter yokugcina amandla, abaguquli abancinci bokugcina amandla, abaguquli bokugcina amandla aphakathi, kunye nabaguquli bokugcina amandla aphakathi.isixhobo sokuhamba, njl.
I-Photovoltaic energy yokugcina i-hybrid kunye ne-low-power-converter yokugcina amandla isetyenziswa kwiimeko zendlu kunye nezoshishino kunye nezorhwebo.Ukuveliswa kwamandla e-Photovoltaic kungasetyenziswa yimithwalo yendawo kuqala, kwaye amandla angaphezulu agcinwe kwibhetri.Xa kusekho amandla angaphezulu, inokudityaniswa ngokukhethiweyo.kwigridi.
Amandla aphakathi, abaguquli bokugcina amandla aphakathi bangakwazi ukufikelela kumandla aphezulu aphezulu kwaye basetyenziswe kwimizi-mveliso kunye nezorhwebo, izikhululo zamandla, iigridi zamandla amakhulu kunye nezinye iimeko zokuphumeza ukucheba i-peak, ukuzaliswa kwentlambo, ukucheba i-peak / modulation frequency kunye neminye imisebenzi.
2. Ukudlala indima egqibeleleyo kwikhonkco lemizi-mveliso
Electro Iinkqubo zokugcina amandla ekhemikhali ngokubanzi zibandakanya iinxalenye ezine eziphambili: ibhetri, inkqubo yolawulo lwamandla (EMS), inverter yokugcina amandla (PCS), kunye nenkqubo yokulawula ibhetri (BMS).
I-inverter yokugcina amandla inokulawula inkqubo yokutshaja kunye nokukhuphaibhetri yokugcina amandlakunye nokuguqula i-AC kwi-DC, edlala indima ebaluleke kakhulu kwitsheyini yezoshishino.
Emantla: izinto zebhetri, ababoneleli becandelo le-elektroniki, njl.;
I-Midstream: abahlanganisi benkqubo yokugcina amandla kunye nabafakeli benkqubo;
Ukuphela kwesicelo esisezantsi: izikhululo zamandla zomoya kunye ne-photovoltaic,iinkqubo zegridi zamandla, ikhaya / amashishini kunye nezorhwebo, abaqhubi bonxibelelwano, amaziko edatha kunye nabanye abasebenzisi bokugqibela.
Inverter ye-Photovoltaic
I-Photovoltaic inverter yi-inverter ezinikele kwintsimi ye-solar photovoltaic power generation.Owona msebenzi wawo mkhulu kukuguqula amandla eDC aveliswa ziiseli zelanga zibe ngamandla e-AC anokuthi adityaniswe ngokuthe ngqo kwigridi kunye nomthwalo ngokusebenzisa iteknoloji yokuguqula amandla ombane.
Njengesixhobo sokujongana phakathi kweeseli ze-photovoltaic kunye negridi yamandla, i-photovoltaic inverter iguqula amandla eeseli ze-photovoltaic zibe ngamandla e-AC kwaye idlulisele kwigridi yamandla.Idlala indima ebalulekileyo kwi-photovoltaic igridi edibeneyo yokuvelisa amandla.
Ngokukhuthazwa kwe-BIPV, ukwenzela ukwandisa ukusebenza kakuhle kokuguqulwa kwamandla elanga ngelixa kuthathelwa ingqalelo inkangeleko entle yesakhiwo, iimfuno zeemilo ze-inverter zihluka ngokuthe ngcembe.Okwangoku, iindlela eziqhelekileyo ze-solar inverter zezi: inverter centralized, inverter string, inverter multi-string kunye ne-component inverter (micro-inverter).
Ukufana kunye noMahluko phakathi koLight / Storage Inverters
"Iqabane elingcono kakhulu": I-Photovoltaic inverters inokuvelisa umbane kuphela emini, kwaye umbane owenziweyo uchaphazeleka yimozulu kwaye unokungaqiniseki kunye neminye imiba.
Umguquleli wokugcina amandla unokusombulula ngokugqibeleleyo obu bunzima.Xa umthwalo uphantsi, amandla ombane aphumayo agcinwa kwibhetri.Xa umthwalo uphezulu, amandla ombane agciniweyo akhululwa ukunciphisa uxinzelelo kwigridi yamandla.Xa igridi yamandla isilela, itshintshela kwimowudi ye-off-grid ukuqhubeka nokubonelela ngombane.
Umahluko omkhulu: Imfuno ye-inverters kwiimeko zokugcina amandla inzima ngakumbi kune-photovoltaic grid-connected scenarios.
Ukongeza kwi-DC kuguqulelo lwe-AC, kufuneka ibe nemisebenzi efana nokuguqulwa ukusuka kwi-AC ukuya kwi-DC kunye nokutshintsha ngokukhawuleza kwegridi.Kwangaxeshanye, iPCS yokugcina amandla ikwayi-bidirectional converter enolawulo lwamandla kuzo zombini izikhokelo zokutshaja kunye nokukhupha.
Ngamanye amazwi, ii-inverters zokugcina amandla zinemiqobo ephezulu yobugcisa.
Omnye umahluko ubonakala kwezi ngongoma zintathu zilandelayo:
1. Izinga lokusebenzisa i-self-userters ye-photovoltaic yendabuko yi-20% kuphela, ngelixa izinga lokusebenzisa ukuguqulwa kwamandla okugcina amandla liphezulu kwi-80%;
2. Xa amandla amakhulu ehluleka, ii-photovoltaic grid-eqhagamshelwe inverterukhubazekile, kodwa isiguquli sokugcina amandla sinokusebenza ngokufanelekileyo;
3. Kwimeko yokunciphisa okuqhubekayo kwinkxaso-mali yokuvelisa umbane oxhunywe kwigridi, ingeniso yokuguqula amandla okugcina amandla iphezulu kune-photovoltaic inverters.
