7.2 Optimization tswv yim
Raws li cov txiaj ntsig ntawm cov ntsuas ntsuas saum toj no, pab pawg tshawb fawb tso tawm cov lus pom zoo hauv qab no los txhim kho kev sib raug zoo ntawm hnub ci inverters thiab photovoltaic modules:
Txhim kho qhov tseeb ntawm cov hluav taws xob tsis sib xws: Rau kev sib txuas nrog cov hluav taws xob loj sib txawv, cov tuam txhab inverter tuaj yeem txhim kho kev tsim hluav taws xob thiab txais yuav cov kev tswj xyuas hluav taws xob kom raug ntau dua los ua kom cov tswv yim voltage ntau ntawm lub inverter hloov tau mus rau qhov siab tshaj plaws ntawm qhov hluav taws xob ntawm qhov sib txawv photovoltaic modules. Piv txwv li, tsim ib lub inverter nrog ib tug dav voltage input ntau yam uas yuav cia li txheeb xyuas thiab kho cov input voltage los xyuas kom meej tias qhov voltage txuam deviation nrog lub photovoltaic module yog tswj nyob rau hauv 2%. Rau qhov teeb meem sib txuam tam sim no, photovoltaic module manufacturers yuav tsum ntxiv txhim kho kev ruaj ntseg ntawm cov txheej txheem ntau lawm thiab txo cov zis tam sim no hloov pauv ntawm lub module ntawm lub zog siab tshaj plaws; Nyob rau tib lub sijhawm, cov tuam txhab inverter tuaj yeem nce qhov pib ntawm kev tiv thaiv overload kom nws tuaj yeem tiv taus qee qhov tam sim no overload nyob rau hauv lub sijhawm luv luv, zam kev kaw inverter vim tam sim no tam sim no tshaj qhov ntsuas ntau.
Txhim kho ib puag ncig adaptability tsim: Rau kev sib txuas nrog cov tsis zoo kub hloov pauv, cov tuam txhab inverter yuav tsum txhim kho kev tsim cov cua sov dissipation system, txais yuav cov khoom siv hluav taws xob zoo dua thiab cov txheej txheem cua sov, thiab xyuas kom meej tias qhov kub ntawm lub inverter tuaj yeem tswj tau zoo nyob rau hauv qhov kub thiab txias; Nyob rau tib lub sijhawm, ua kom zoo dua qhov ntsuas kub qis ntawm cov khoom siv hluav taws xob kom lawv tseem tuaj yeem pib thiab ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias. Rau cov av noo adaptability teeb meem, PV module thiab inverter manufacturers yuav tsum ntxiv dag zog rau lub sealing kev ua tau zoo ntawm cov khoom, txais yuav waterproof thiab noo noo-pov thawj ntim cov ntaub ntawv thiab sealing txheej txheem, txhim kho qib kev tiv thaiv ntawm sab hauv Cheebtsam, thiab tiv thaiv kom txhob ya raws. Nyob rau hauv cov nqe lus ntawm qhov chaw siab adaptability, inverter manufacturers yuav tsum tau redesigns hluav taws xob clearances thiab rwb thaiv tsev lub zog kom tau raws li cov kev cai tshwj xeeb ntawm cov huab cua nyias nyob rau hauv high-altitude cheeb tsam, thiab xyuas kom meej tias cov cuab yeej muaj peev xwm ua hauj lwm yam xyuam xim thiab stably nyob rau hauv high-altitude ib puag ncig.
Txhim kho qhov kev sib koom ua ke ntawm qhov siab tshaj plaws ntawm lub zog taw tes nrhiav: Inverter manufacturers yuav tsum nce peev hauv kev tshawb fawb thiab kev loj hlob ntawm MPPT algorithms, txhim kho sai dua thiab muaj tseeb dua kev taug qab algorithms, thiab tuaj yeem saib xyuas cov khoom tsim tawm ntawm PV modules hauv lub sijhawm tiag tiag, thiab kho cov xwm txheej ua haujlwm ntawm lub inverter kom ua tiav qhov kev taug qab ntawm lub zog siab tshaj plaws. Piv txwv li, siv cov cuab yeej siv thev naus laus zis los saib xyuas lub teeb siv thiab qhov kub thiab txias hloov hauv lub sijhawm, ua ke nrog cov tswv yim ntse kom hloov kho MPPT, kom lub zog tsim hluav taws xob tuaj yeem tswj tau siab dua 95% nyob rau hauv cov teeb pom kev sib txawv. Nyob rau tib lub sijhawm, PV module manufacturers yuav tsum tau muab cov ncauj lus kom ntxaws module yam ntxwv.parameters kom cov tuam txhab inverter tuaj yeem ua kom zoo dua MPPT algorithm thiab txhim kho kev sib koom ua haujlwm.
Txhim khu kev tswj kom zoo thiab kev siv tus qauv: Cov neeg tsim khoom yuav tsum nruj me ntsis ua raws li cov txheej txheem thoob ntiaj teb thiab hauv tsev rau kev tsim khoom thiab kev tswj xyuas kom zoo kom ntseeg tau tias txhua pawg ntawm cov khoom ua tau raws li cov qauv kev cai. Thaum lub sij hawm tsim cov txheej txheem, ntxiv dag zog rau kev tshuaj xyuas cov khoom siv raw, kev soj ntsuam cov txheej txheem tsim khoom thiab kev tshuaj xyuas cov khoom tiav kom txo tau cov teeb meem sib raug zoo los ntawm kev hloov pauv zoo hauv cov txheej txheem tsim khoom. Nyob rau tib lub sijhawm, nws raug pom zoo kom cov koom haum tsim cov txheej txheem txuas ntxiv txhim kho thiab ua kom zoo dua cov qauv thiab cov kev qhia tshwj xeeb rau kev ntsuas kev sib raug zoo ntawm lub hnub ci inverters thiab photovoltaic modules, thiab ntxiv cov khoom sim ntxiv rau cov ntawv thov tiag tiag, xws li kev ntsuas kev sib raug zoo hauv thaj chaw sib txawv (xws li roob, tiaj, suab puam, thiab lwm yam), thiab lwm yam kev teeb tsa hauv av, thiab lwm yam, xws li kev teeb tsa hauv av, thiab lwm yam. Kev ntsuas kev sib raug zoo ntawm cov khoom thiab muab cov neeg siv nrog lub hauv paus tseeb dua rau kev xaiv cov khoom tsim nyog.
Ua kom muaj kev sib koom ua ke R & D thiab kev sim: PV module manufacturers thiab inverter manufacturers yuav tsum ntxiv dag zog rau kev koom tes thiab ua tiav kev sib koom R & D thiab kev sim ua haujlwm. Los ntawm kev sib koom cov kev pab cuam thiab cov ntaub ntawv xeem, sib koom ua ke txhim kho cov khoom tsim thiab txhim kho kev sib raug zoo. Piv txwv li, ob tog tuaj yeem sib koom ua ke tsim ib qho kev sib koom ua ke los ua qhov kev sib tw loj loj ntawm cov khoom siv hluav taws xob PV thiab cov qauv inverter hauv kev ua lag luam, txheeb xyuas cov yam ntxwv ntawm kev ua tau zoo thiab cov teeb meem uas twb muaj lawm ntawm kev sib txawv ntawm kev sib txuas, thiab ua cov phiaj xwm kev txhim kho.
