Izinhlobo zama-inverters okugcina amandla asendlini
Ama-inverter okugcina amandla okuhlala angahlukaniswa abe izindlela ezimbili zobuchwepheshe: i-DC coupling kanye ne-AC coupling.Kusistimu yokugcina i-photovoltaic, izingxenye ezihlukahlukene ezifana namaphaneli elanga nengilazi ye-PV, izilawuli, ama-solar inverters, amabhethri, imithwalo (izinto zikagesi), nezinye izinto zokusebenza zisebenza ndawonye.Ukuhlanganisa i-AC noma i-DC kubhekisela endleleni amaphaneli elanga axhunywe ngayo endaweni yokugcina amandla noma amasistimu ebhethri.Ukuxhumana phakathi kwamamojula elanga namabhethri e-ESS kungaba yi-AC noma i-DC.Nakuba amasekhethi amaningi e-elekthronikhi esebenzisa i-direct current(DC), amamojula elanga akhiqiza amandla aqondile, futhi amabhethri elanga asekhaya agcina amanje aqondile, izinto zikagesi eziningi zidinga ukushintshana kwamanje(AC) ukuze zisebenze.
Kusistimu yokugcina amandla elanga exubile, amandla akhona aqondile akhiqizwa amaphaneli elanga agcinwa kuphakethe lebhethri ngesilawuli.Ukwengeza, igridi ingaphinda ishaje ibhethri ngesiguquli se-DC-AC esinezinhlangothi ezimbili.Iphoyinti lokuhlangana lamandla lisekupheleni kwebhethri le-DC BESS.Emini, ukukhiqizwa kwamandla e-photovoltaic kuqala kunikeza umthwalo (imikhiqizo kagesi yasendlini) bese ishaja ibhethri ngesilawuli selanga se-MPPT.Isistimu yokugcina amandla ixhunywe kugridi yezwe, okuvumela amandla engeziwe ukuthi afakwe kugridi.Ebusuku, ibhethri liyaphuma ukuze linikeze amandla kumthwalo, nanoma yikuphi ukushoda okulekelelwa igridi.Kuyaphawuleka ukuthi amabhethri e-lithium anikezela ngamandla kuphela emithwalweni engaphandle kwegridi futhi awakwazi ukusetshenziselwa imithwalo exhunywe kugridi lapho igridi yamandla isiphelile.Ezimeni lapho amandla okulayisha edlula amandla e-PV, kokubili igridi nesistimu yebhethri yelanga inganikeza amandla ekulayisheni ngesikhathi esisodwa.Ibhethri idlala indima ebalulekile ekulinganiseni amandla esistimu ngenxa yokuguquguquka kwemvelo yokukhiqiza amandla e-photovoltaic kanye nokusetshenziswa kwamandla okulayisha.Ngaphezu kwalokho, uhlelo luvumela abasebenzisi ukuthi bahlele izikhathi zokushaja nokukhipha amandla ukuze bahlangabezane nezidingo zabo ezithile zikagesi.
Indlela I-DC Coupled Energy Storage System esebenza ngayo
IHybrid photovoltaic + isistimu yokugcina amandla
I-solar hybrid inverter ihlanganisa ukusebenza kwegridi yokuvula nokuvala ukuze kuthuthukiswe ukusebenza kahle kokushaja.Ngokungafani neziguquli ze-on-grid, ezinqamula ngokuzenzakalelayo isistimu yephaneli yelanga phakathi nokuphela kukagesi ngenxa yezizathu zokuphepha, ama-inverter ayingxube anikeza abasebenzisi ikhono lokusebenzisa amandla ngisho nalapho ukucima kukagesi, njengoba engakwazi ukusebenza kokubili ngaphandle kwegridi futhi exhunywe kugridi.Inzuzo yama-hybrid inverter wukuqapha kwamandla okwenziwe lula abakunikezayo.Abasebenzisi bangafinyelela kalula idatha ebalulekile efana nokusebenza namandla okukhiqiza ngephaneli yokuguqula noma kumadivayisi ahlakaniphile axhunyiwe.Ezimweni lapho uhlelo luhlanganisa ama-inverter amabili, ngalinye kufanele liqashwe ngokwehlukana.I-DC coupling isetshenziswa kuma-inverter ayi-hybrid ukuze kuncishiswe ukulahlekelwa ekuguquleni kwe-AC-DC.Ukusebenza kahle kokushaja kwebhethri ngokuhlangana kwe-DC kungafinyelela cishe ku-95-99%, uma kuqhathaniswa no-90% ngokuhlangana kwe-AC.
Ngaphezu kwalokho, ama-inverter ayi-hybrid ayonga, ahlangene, futhi kulula ukuyifaka.Ukufaka i-inverter entsha eyi-hybrid ngamabhethri ahlanganiswe ne-DC kungase kubize kakhulu kunokubuyisela amabhethri ahlanganiswe ne-AC ohlelweni olukhona.Izilawuli zelanga ezisetshenziswa kuma-inverters e-hybrid zibiza kancane kunama-inverters aboshwe ngegridi, kuyilapho ukushintshwa kokudlulisa kubiza kancane kunamakhabethe okusabalalisa kagesi.I-DC ehlanganisa i-solar inverter ingase futhi ihlanganise imisebenzi yokulawula kanye ne-inverter emshinini owodwa, okuholela ekongeni okwengeziwe kwemishini kanye nezindleko zokufaka.Ukusebenza kahle kwezindleko zohlelo lokuhlanganisa lwe-DC kugqama kakhulu ezinhlelweni zokugcina amandla egridi amancane naphakathi nendawo.Idizayini ye-modular yama-inverter ayi-hybrid ivumela ukungezwa kalula kwezingxenye nezilawuli, ngenketho yokuhlanganisa izingxenye ezengeziwe kusetshenziswa isilawuli selanga se-DC esingabizi kakhulu.Ama-inverter amaHybrid nawo aklanyelwe ukwenza lula ukuhlanganiswa kwesitoreji nganoma yisiphi isikhathi, ukwenza lula inqubo yokwengeza amaphakethe ebhethri.I-hybrid inverter system ibonakala ngosayizi wayo ohlangene, ukusetshenziswa kwamabhethri ane-voltage ephezulu, nosayizi abancishisiwe bekhebula, okuholela ekulahlekeni okuphansi sekukonke.
