Uyini Umehluko Phakathi kwe-PCS Yesitoreji Esikhulu, Sezentengiso Nesezimboni kanye Nesitoreji Sasekhaya?

Kweukugcinwa kwamandlaimboni, i-PCS, noma i-Power Conversion System, isiguquli sokugcina amandla.

Ukugcinwa kwebhethri kuvame ukuhlukaniswa ngezimo ezintathu ezinkulu zohlelo: isitoreji esikhulu, isitoreji sezentengiselwano nesezimboni, nesitoreji sasendlini, kanye nama-PCS/inverter ahambisanayo ezimeni ezahlukene nawo ahluke kakhulu. Lesi sihloko sihlukanisa i-PCS ngesitoreji esikhulu, i-PCS yokugcina izimboni nezentengiso, kanye ne-PCS yokugcina indlu kusukela ezigabeni ezine ezibanzi: isikali samandla, izimo zohlelo lokusebenza, izidingo zobuchwepheshe, izindleko kanye nentengo, ngokulandelana.

I. Isikali Samandla

Ama-PC amakhulu wesitoreji:

Izinga lamandla liphezulu, ngokuvamile ezingeni le-MW (megawatt), lingaba phezulu njenge-100MW noma ngaphezulu. Amasistimu amakhulu okugcina amandla angagcina kufika emahoreni ama-megawatt ambalwa noma ngisho namakhulu amandla wama-megawathi ukuze afane nezidingo zegridi enkulu yokugcina amandla, ukuze kuzuzwe ukulawulwa kwefrikhwensi yegridi, ukushintshwa okuphezulu kanye neminye imisebenzi.

I-PCS yezohwebo nezimboni:

Amandla ngokuvamile aphakathi kwamashumi kW (kilowatts) kanye nama-MW amaningana. Isebenza kubasebenzisi bezimboni nabezentengiselwano, umthamo wokugcina usukela kumakhulu ambalwa ama-kWh ukuya ezinkulungwaneni ezimbalwa ze-kWh, ezisetshenziselwa ukubhekana nezintengo eziphezulu kanye nokuhlangabezana nezidingo zokuthembeka kwamandla.

I-PCS Yesitoreji Sasekhaya:

Amandla amancane uma kuqhathaniswa, ngokuvamile aphakathi kwama-kW ambalwa kanye neshumi nambili kW. Isebenza ikakhulukazi isitoreji sasendlini se-PV esiphehla ugesi namandla aphuthumayo,isistimu yokugcina amandla yasendliniumthamo ngokuvamile usebangeni lama-kWh ambalwa kuya emashumini e-kWh.

II. Izimo zohlelo lokusebenza

Ama-PC amakhulu wesitoreji:

I-grid-side: ukulinganisa ukunikezwa kanye nesidingo segridi, ukwenza bushelelezi ukuphuma ngezikhathi ezithile kwamandla omoya kanye nokukhiqizwa kwamandla e-photovoltaic, nokuthuthukisa ikhwalithi nokuzinza kwamandla wegridi. Isibonelo, uma isiteshi samandla esikhulu se-photovoltaic sixhunywe kugridi, singagcina amandla engeziwe emini futhi sikhulule amandla ebusuku noma ezinsukwini eziguqubele.

Ukusekela iziteshi ezinkulu zikagesi: sebenzisana neziteshi ezinkulu zikagesi ezishisayo noma ezisebenza ngamanzi ukuze kuqhutshekwe nokulawulwa kwamafrikhwensi ahlanganyelwe, kuphendule ngokushesha isidingo sokulawulwa kwefrikhwensi yegridi, futhi kuthuthukiswe ukusebenza kokulawula imvamisa kohlelo lwamandla.

I-PCS yezohwebo nezimboni:

Ukushefa okuphezulu nokugcwalisa izigodi: abasebenzisi bezimboni nabezentengiselwano bagcina ugesi ngesikhathi sentengo kagesi futhi bawukhulule ngesikhathi esiphezulu ukuze banciphise izindleko zokusetshenziswa kukagesi. Isibonelo, izikhungo zedatha ziyashaja ebusuku futhi zikhiphe emini ukuze kuncishiswe isidingo samandla aphezulu avela kugridi.

Isiqinisekiso sokuphakelwa kwamandla esimeni esiphuthumayo: Nikeza ukwesekwa kwamandla ezimo eziphuthumayo ezinsizeni ezibalulekile zamabhizinisi lapho igridi yamandla ihluleka, futhi uqinisekise ukusebenza okuyisisekelo kwamabhizinisi nokusebenza okuvamile kwezinsiza ezibalulekile.

I-PCS Yesitoreji Sasekhaya:

Ukusekelwa kokukhiqizwa kwamandla e-photovoltaic yasendlini: kusebenza ngokuhambisana nesistimu ye-solar photovoltaic yasendlini ukuguqula amandla e-DC abe amandla e-AC ukuze asetshenziswe ekhaya, ngamandla engeziwe agcinwe ebhethrini ukuze kuthuthukiswe ukukwazi ukwanelisa ikhaya.

Amandla Ayisipele Esiphuthumayo: Ihlinzeka ngokuvikeleka kwamandla okuyisisekelo ezindlini ngesikhathi sokuphela kwegridi, igcina ukusebenza kwezinto ezibalulekile ezifana nezibani, iziqandisi, nemishini yokuxhumana.

Ⅲ. Izidingo Zobuchwepheshe

Ama-PC amakhulu wesitoreji:

Ukusebenza kahle kokuguqulwa: ukuguqulwa okuphezulu ukusebenza kahle kuyadingeka, ngokuvamile ngaphezu kwama-95%, ukunciphisa ukulahleka kwamandla kanye nokwenza ngcono umnotho wesistimu yokugcina amandla.

Isivinini sokuphendula: Ingakwazi ukuphendula ngokushesha emiyalweni yokuthumela igridi, ilungise ukushaja namandla okukhipha ngama-millisecond ukuze igcine ukuqina kwegridi.

Ukuhambisana kwesistimu: ukuhambisana okuhle namasistimu ebhethri okugcina amandla amakhulu kanye nezinhlelo zegridi eziyinkimbinkimbi, ezijwayelana nezici zebhethri ezihlukene kanye nezidingo zokufinyelela kugridi.

I-PCS yokugcina izimboni nezentengiso:

Ukuthembeka: ukuthembeka okuphezulu, ukunciphisa isikhathi sokuphumula kwephutha, ukuhlangabezanaizimboni nezohweboukukhiqizwa okuqhubekayo noma izidingo zokusebenza, zidinga isikhathi eside esimaphakathi esingenaphutha.

I-Power Factor Regulation: Ilawula ngempumelelo isici samandla, ithuthukisa ikhwalithi yamandla kubasebenzisi bezimboni nabezentengiselwano, futhi yehlisa izindleko zikagesi wenkampani ngokusebenzisa isinxephezelo samandla asebenzayo.

I-PCS yesitoreji sasekhaya:

Ukuphepha: ngohlelo oluphelele lokuphatha ibhethri ukuvimbela ukushajwa ngokweqile, ukushajwa ngokweqile kanye nokufinyezwa kwesekhethi yamabhethri ukuze kuqinisekiswe ukuphepha komuntu siqu nempahla yabasebenzisi basekhaya.

Ukusebenziseka kalula: kulula ukuyisebenzisa nokuyinakekela, ene-interface elula neqondakala kalula, kulula ukuyifaka futhi ihlanganiswe ohlelweni lwamandla asendlini.

Ⅳ. Izindleko Namanani

Ama-PC amakhulu wesitoreji:

Izindleko ziphezulu, futhi amanani angase abe ezinkulungwaneni zamadola nge-kilowatt ngayinye. Amandla aphezulu, izidingo zobuchwepheshe eziyinkimbinkimbi, kanye nokukhiqizwa kokukhiqizwa ngobuningi kuphumela ku-R&D ephezulu, impahla eluhlaza, nezindleko zokukhiqiza, kodwa amanani ehla kancane kancane ngemiphumela yesilinganiso nokuthuthuka kwezobuchwepheshe.

I-PCS yezohwebo nezimboni:

Izindleko nentengo kuphakathi kwe-PCS yesitoreji esikhulu ne-PCS yesitoreji sasendlini, futhi intengo nge-kW ngayinye ingase ibe cishe ku-1000 - 5000 Dollars. Intengo ithintwa amandla, umsebenzi, umkhiqizo nezinye izici, ukubuyisela ekutshalweni kwezimali kuyisici esibalulekile kubasebenzisi bezimboni nabezentengiselwano ukuthi bacabangele ukuthenga.

I-PCS Yesitoreji Sasekhaya:

Izindleko ziphansi uma kuqhathaniswa, futhi intengo nge-kW ngayinye ingase isuke kumakhulu ambalwa amadola ukuya cishe ku-2,000 dollars. Amandla mancane, umsebenzi ulula uma kuqhathaniswa, ngokwanda kwemakethe yokugcina amandla yasendlini, intengo kulindeleke ukuthi iphinde yehliswe ukuze kuthuthukiswe ukwamukelwa kwabasebenzisi basekhaya.

I-PCS yesitoreji esikhulu segridi enkulu kanye nezicelo zesiteshi samandla, amandla aphezulu, izidingo eziqinile zobuchwepheshe, izindleko eziphezulu; Izinsiza zezimboni nezohwebo ze-PCS zokushefa nezimo eziphuthumayo zezimboni nezohwebo, amandla amaphakathi, ukuthembeka okukhulu, njll., izindleko eziphakathi; i-PCS yokugcina indlu ye-PV yasekhaya kanye nokusetshenziswa okuphuthumayo, amandla amancane, ukuphepha kwenothi nokusebenziseka kalula, izindleko eziphansi.
