Raws li cov ntsiab lus tseem ceeb ntawm kev tsim hluav taws xob photovoltaic thiab lub zog khaws cia, inverters muaj npe nrov. Thaum muaj coob tus neeg pom tias lawv muaj tib lub npe thiab siv tib lub teb, lawv yuam kev xav tias lawv yog tib hom khoom, tab sis qhov tseeb lawv tsis yog. Photovoltaics thiab lub zog cia inverters tsis yog tsuas yog "cov neeg koom tes zoo tshaj plaws", tab sis lawv kuj sib txawv hauv kev siv tswv yim xws li kev ua haujlwm, kev siv tus nqi, thiab cov nyiaj tau los.
Lub zog cia inverter
Lub zog cia converter (PCS), tseem hu ua "bidirectional zog cia inverter", yog lub ntsiab lus tseem ceeb uas paub txog ob txoj kev ntws ntawm hluav taws xob hluav taws xob ntawm lub zog cia thiab daim phiaj hluav taws xob. Nws yog siv los tswj cov txheej txheem them thiab tawm ntawm lub roj teeb thiab ua AC thiab DC hloov. Hloov pauv. Nws tuaj yeem muab hluav taws xob ncaj qha rau AC loads thaum tsis muaj daim phiaj hluav taws xob. 1. Cov qauv kev khiav hauj lwm yooj yim Raws li daim ntawv thov scenarios thiab muaj peev xwm ntawm lub zog cia converters, lub zog cia converters tau muab faib ua photovoltaic zog cia hybrid converters, me me zog zog cia converters, nruab nrab lub zog cia converters, Centralized zog cia converter, thiab lwm yam.
Photovoltaic zog cia hybrid thiab qis zog lub zog cia converters yog siv nyob rau hauv tsev neeg thiab kev lag luam thiab kev lag luam scenarios. Kev tsim hluav taws xob photovoltaic tuaj yeem siv los ntawm cov khoom hauv zos ua ntej, thiab lub zog ntau dhau yog khaws cia hauv lub roj teeb. Thaum tseem muaj zog dhau lawm, nws tuaj yeem xaiv ua ke. rau hauv daim phiaj.
Nruab nrab-lub zog, nruab nrab lub zog cia converters tuaj yeem ua tiav lub zog tso zis ntau dua thiab siv rau hauv kev lag luam thiab kev lag luam, chaw nres tsheb fais fab, daim phiaj hluav taws xob loj thiab lwm yam xwm txheej kom ua tiav lub ncov shaving, hav filling, ncov shaving / zaus hloov kho thiab lwm yam haujlwm.
2. Lub tshuab hluav taws xob hluav taws xob hluav taws xob, uas ua lub luag haujlwm tseem ceeb hauv kev lag luam, feem ntau muaj plaub qhov tseem ceeb: roj teeb, lub zog tswj kev siv hluav taws xob (EMS), lub zog cia inverter (PCS), thiab roj teeb tswj system (BMS). Lub zog cia inverter tuaj yeem tswj cov txheej txheem them thiab tawm ntawm lub zog cia roj teeb thiab hloov AC rau DC, uas ua lub luag haujlwm tseem ceeb hauv cov saw hlau.
Upstream: roj teeb raw khoom, khoom siv hluav taws xob, thiab lwm yam .;
Midstream: lub zog cia system integrators thiab system installers;
Daim ntawv thov nram qab kawg: cua thiab photovoltaic fais fab chaw nres tsheb, fais fab fais fab, tsev neeg / kev lag luam thiab kev lag luam, kev sib txuas lus, cov chaw zov me nyuam thiab lwm cov neeg siv kawg.
Photovoltaic inverter
Photovoltaic inverter yog lub inverter nplooj siab rau thaj chaw ntawm hnub ci photovoltaic zog tsim. Nws txoj haujlwm loj tshaj plaws yog hloov DC lub zog tsim los ntawm lub hnub ci hlwb rau hauv AC lub zog uas tuaj yeem ncaj qha mus rau hauv daim phiaj thiab thauj khoom los ntawm lub zog hluav taws xob hloov tshuab hluav taws xob.
Raws li cov cuab yeej sib txuas ntawm cov cell photovoltaic thiab daim phiaj hluav taws xob, lub photovoltaic inverter hloov lub zog ntawm cov hlwb photovoltaic rau hauv AC lub zog thiab xa mus rau daim phiaj hluav taws xob. Nws plays lub luag haujlwm tseem ceeb hauv photovoltaic daim phiaj-txuas lub zog tsim hluav taws xob. Nrog rau kev nce qib ntawm BIPV, txhawm rau ua kom muaj txiaj ntsig zoo tshaj plaws ntawm kev hloov pauv ntawm lub hnub ci zog thaum coj mus rau hauv tus account qhov zoo nkauj ntawm lub tsev, cov kev xav tau rau cov duab inverter yog maj mam diversified. Tam sim no, cov txheej txheem hnub ci inverter yog: centralized inverter, hlua inverter, ntau txoj hlua inverter thiab tivthaiv inverter (micro-inverter).
Zoo sib xws thiab qhov sib txawv ntawm Lub Teeb / Cia Inverters
"Tus khub zoo tshaj plaws": Photovoltaic inverters tsuas tuaj yeem tsim hluav taws xob thaum nruab hnub, thiab lub zog tsim hluav taws xob cuam tshuam los ntawm huab cua thiab tsis tuaj yeem kwv yees.
Lub zog cia converter tuaj yeem daws cov teeb meem no zoo kawg nkaus. Thaum lub load tsawg, cov zis hluav taws xob yog khaws cia rau hauv lub roj teeb; thaum lub load yog siab tshaj, cov khoom siv hluav taws xob tso tawm kom txo tau qhov siab ntawm daim phiaj fais fab; thaum daim phiaj hluav taws xob tsis ua haujlwm, nws hloov mus rau off-grid hom kom muab lub zog txuas ntxiv.
Qhov sib txawv loj tshaj: Qhov kev thov rau inverters nyob rau hauv lub zog cia scenarios yog ntau nyuaj tshaj nyob rau hauv photovoltaic daim phiaj-txuas scenarios.
Ntxiv rau DC rau AC hloov dua siab tshiab, nws kuj yuav tsum muaj kev ua haujlwm xws li kev hloov pauv ntawm AC rau DC thiab kev hloov pauv ceev ceev. Nyob rau tib lub sijhawm, lub zog cia PCS kuj yog ib qho kev hloov pauv bidirectional nrog lub zog tswj hauv ob qho tib si them thiab tawm cov lus qhia. Hauv lwm lo lus, lub zog cia inverters muaj kev cuam tshuam ntau dua.
Lwm qhov sib txawv tau pom hauv peb lub ntsiab lus hauv qab no:
1. Tus kheej siv tus nqi ntawm cov tsoos photovoltaic inverters tsuas yog 20%, thaum tus kheej siv tus nqi ntawm lub zog cia converters yog siab li 80%;
2. Thaum lub zog hluav taws xob tsis ua haujlwm, lub photovoltaic daim phiaj-txuas inverter yog tuag tes tuag taw, tab sis lub zog cia converter tseem tuaj yeem ua haujlwm tau zoo;
3. Nyob rau hauv cov ntsiab lus ntawm kev txo qis hauv cov nyiaj pab rau kev sib txuas hluav taws xob sib txuas, cov nyiaj tau los ntawm cov khoom siv hluav taws xob khaws cia yog siab dua li ntawm photovoltaic inverters.
Photovoltaic inverters thiab lub zog cia inverters sib txawv hauv kev tsim thiab lub hom phiaj. Yog tias koj tab tom xav txog kev txhim kho lub hnub ci hluav taws xob tsim hluav taws xob lossis lub zog cia, nws raug nquahu kom xaiv cov khoom siv inverter raws li qhov xav tau tiag tiag.
