Amathransfomathi okukhokha kwezilayili, i-BESS, nokuvulwa kwamandla ngokugcina

Amakhaya okuhambisa amandla okuzo kahle akazalwa ngokusebenzisa imodeli yokuqasha komandla: amandla ayehlisa kusuka kumkhaya wokuhambisa amandla ngapha kwezitshixo sokuhambisa amandla bese ayehlisa kubantu abasebenzisa. i-solar PV, izinhlangano zokugcina amandla (BESS), imicrogrids, nezinhlangano zokusebenza ngokufanayo ziyishintsha le modeli.

Itransforma yomkhakha wokuphatha amandla ayisodwa kungase kufanele isebenze ngokuphatha amandla kumithambo eminye. Ngeminyaka yokuqhubeka kwe-solar, amandla angathola kusuka kwezinhlangano zama-solar kusukela kumkhakha wokuphatha amandla. I-BESS ingathola amandla kusuka kumkhakha wokuphatha amandla noma kusuka kwezinhlangano zama-solar ngemva kwalokho, ngokuthi iphatha amandla kubantu abasebenzisa kuleli xesha noma kumkhakha wokuphatha amandla ngemva kwalokho.

Le ndlela eyishintshwa yokusebenza kwenza ukuthi kubhekwe izinkinga zokugcina izinto ezikhona zokuzimela ngokuphelele kwe- i-transforma yomkhakha wokuphatha amandla kwe-solar , i-transforma yama-BESS, nezinhlangano zokuphatha amandla ngemithambo eminye . Ukukhala kwesikhala, ukulungiswa kwesikhala, ukulinganisa, ukuphatha kwezinkokhelo, ukuphatha kwezinhlangano zokuhambisana, ukuphatha kwezinhlangano zokuvumela, ukujabula, nokuthi ukuthi kuyisiphi isikhala sokuvumela umkhakha wokuphatha amandla kufanele kubhekwe njengendlela eyisodwa.

Ngoba ngumshumayeli nomshumayeli wokuphakamisa amasosha okuphakamisa, U-Dingxin Electric iyaphinda iziphumo zokugcina izinto ezikhona zokuzimela ngokuphelele kwezinhlangano zama-solar PV, ama-BESS, amicrogrid, amakhakha wokuphatha amandla, amakhakha wokusebenza kwezindustria, nezinhlangano zokusebenza kwezindawo zokusebenza.

1. Kusuka kwezinhlangano zokuphatha amandla ngomithamo oyodwa kuzinhlangano zokuphatha amandla ngemithambo eminye

Le ndlela yezinhlangano zokuphatha amandla ephansi kuyafanekisa njengoko kuyisodwa:

Umkhakha wokuphatha amandla → I-transforma yomkhakha wokuphatha amandla → Isikhala sokusebenza

Ukusebenza kwe-solar PV nezinkumbulo zokugcina amandla kungakuthintela lokhu ubudlelwano.

Solar PV

Kodwa isikhundla sesolar sisebenza ngamandla angaphezulu kuka-loads yasekhaya:

Umlinganisi wokusebenza → I-transformer → I-load

Kodwa ukusukela kwesolar kuyaphikisa ukusetshenziswa kwekhaya:

Solar PV → I-transformer → Umlinganisi wokusebenza

Lokhu kuchazwa ngokuvamile njengalo: ukuhambisa kwezandla ezinye noma ukusukela kwamandla .

Ukugcina kwe-BESS

Kodwa i-Battery Energy Storage System iqhula, amandla angafika:

Umgangatho / I-Solar PV → I-Transformer → I-BESS

Kumaprojekthi wamasulayi, BESS, nezindlela zokusebenza kwezindawo, uDingxin ungasebenzisa izinkinga zomprojekthi okuphathelene ne- isikhumba, ukuvimba, ukubambisana, isigaba sokuthi isikhathi, ukuthenga isikhumba, ukulima, ukubhala, ukugcina isikhumba, nokuthenga isikhumba .

Ngoba umaprojekthi wokuphila kungasebenza ngemiphumela yezindlela zokusebenza nezindlela zokusebenza kwezindlela zokusebenza, ukukhetha amasulayi kufanele kubase kwezindlela zokusebenza zomprojekthi wonke.

UDingxin ungasebenze nezinkampani zokugcina i-EPC, abadala, abasunguliwe amathuba, izimpahla zokugcina isisiko, izimpahla zokusebenza kwelekthrikhile, nokholwa amathuba okuphatha ukuthi isithembiso sokubeka isithembiso sokufaka isikhundla esihle ngokwesibonelo esinamandla, kodwa akayikwazi ukubhekana ngesithembiso sokubeka isikhundla esihle kuphela.

Imibuzo Evame Ukubuzwa

Umbhalo wokuhambisa we-solar yini?

Umbhalo wokuhambisa we-solar yumbhalo wokuhambisa owasebenzisa ukuxhumeka kwezinhloso zokuphatha i-solar PV kumandla omkhulu okanye kwenye indawo yokuhambisa kwamandla. Isithembiso nakomlando kuyaphendula kumandla we-PV, imigqa yamandla, izinkinga zokuhambisa, umlando wokuxhumeka, nokuthuluzi okusebenzayo.

Umbhalo wokuhambisa we-BESS yini?

Umbhalo wokuhambisa we-BESS uxhuma isistimu yokuqasha amandla wesilika nesiqondiso sakho sesikhundla esihle kusistimu yokuhambisa kwamandla okanye kusistimu yokuthumela amandla. Ngokwesilinganiso sesistimu, umbhalo wokuhambisa kungadinga ukuthuthukisa amandla okuhamba kumaqanda kanye nokuhamba kumaqanda.

Ingaba umbhalo wokuhambisa ungasebenza ngokuhambisa kumaqanda kanye nokuhamba kumaqanda?

I-transformer lingasebenzisa nokubhalwa ngokufanayo kwezindawo ezingaphansi kwezindlela zokusuka kwezinye izindawo, kodwa ukuthi kuyisisekelo sokusebenza kufanele kubhekwe njengesiqondiso sezinhlelo zokusebenza zezindawo zokugcina umoya. Ukuvikela, ukulungisa ivoltij, ukulakha kwemitha, ukulingana, ukugxilwa, nokuxhumeka kwezindawo zokusebenza zokugcina umoya zonke kufanele kubhekwe.

Ukusebenza kwe-solar kwenza ukusuka kwemitha ngokuzingelwa?

I-solar PV ingakwenzela ukusuka kwemitha ngokuzingelwa uma ukusebenza kuyakhula kunezidingo zokusebenza kwezindawo zokugcina umoya kanye nezinkampani ezinconywa ku-izindawo zokugcina umoya zokuphambuka. Ukuthi lokhu kwenza kuthi kubhekwa ngokwesikhundla sokusebenza, isayizi yokuqala kwe-PV, ukugcina kwemitha, nokukhokha kwezinkampani.

I-BESS ikhangelela ukulakha kwe-transformer?

Yebo. I-BESS ingakhangelela ukulakha kwe-transformer uma iyadluliswa futhi ingathumela umoya uma iyadluliswa. Ngakho ke i-transformer kufanele kubhekwe ngokwesikhundla sokudluliswa nokudluliswa kungaphandle kokuthi kuphi ukulakha okuphelele.

Izinhlelo zesi-solar ne-BESS zidala amaharmoniki?

Izinkambo zokusebenza kwe-energi ezinokuthi zibhala amaqhina we-harmonic njengezinkambo zokuguqula kwesolar nezinkambo zokugcina i-BESS. Umsebenzi wokubhala kwe-harmonic ubonakala ngokwesikhathi, futhi kuyisiphumo sokukhetha izinkambo nezindlela zokubeka isistimu, ngakho abasebenzi bokufunda kufanele bahlale bavumela ispekthrem yohlanga lwe-harmonic obonakalayo nezimali zokusebenza kwe-energi ozokubhekwa ngazo.

Ingaba u-Dingxin unakwenzela izitrafomha zesolar nezitrafomha ze-BESS ngokwesikhalo?

Yebo. U-Dingxin unasolusheni esihlukanisiweyo sezitrafomha nezitrafomha zesibhakabhaka esizimele, esibonakalisa ukuthi kusobala ukuthi kubhekwa ngokwesikhalo isivinini, isikhondlo, isikhondlo sesihlukanisi, isigaba se-vector, isikhondlo sesitafu, ukuvula, ukujabulisa, isikhondlo sesibhakabhaka, isikhondlo sesibhakabhaka, nokunye okuthi kubhekwa ngokwesikhalo.

Uyaphanda iprojekthi yesolar, i-BESS, noma iprojekthi yezindawo ezipheleleyo?

Izitrafomha zokuphatha kwe-renewable energy kufanele zibhekwe ngokwesikhalo isikhondlo sokungena kakhulu, isikhondlo sokuhambisa kakhulu, isiprofile sokusebenza, izinqumo zovoltage, ukusebenza kwe-energi, isistratiji yokuvikela, nokuthi kubhekwa ngokwesikhalo ukuthi kuzoba kubhekwa ngokwesikhalo. .

Thumela umlomo wakho wokugcina isikhathi, amavolti we-Primary ne-Secondary, ubukhulu be-transformer, amandla okuhamba kusuka kuma-Import/Export, umdlalo wokusebenza, nokuthi yiziphi izinkinga zokuxhumana ne-utility. Ithimba le-engineering yethu liyakubheka lokhu kanye nokumelisa isikhombiso se-transformer esihlanganisiwe.

Qala ukubona i-Technical Quotation kusuka ku-Dingxin manje yokuphatha kwakho kwe-solar, BESS, microgrid, noma ukuphatha kwe-bidirectional power-flow.
