DC solar zog system Raws li cov nyhuv photovoltaic
Hnub ci zog hauv kev siv lub caij niaj hnub no ntau thiab ntau dua, ces, lub hnub ua hluav taws xob hluav taws xob li cas?
Lub hauv paus ntsiab lus tseem ceeb ntawm hnub ci hluav taws xob tiam yog raws li cov nyhuv ntawm photovoltaic, muab los ntawm lub hnub ci ntawm cov khoom tam sim no. Yog hais tias nws yog tus kab sib chaws los ntawm daim phiaj inverter ncaj qha mus rau hauv daim phiaj fais; yog tias nws tsis yog-daim phiaj los ntawm lub hnub ci tawm mus rau lub roj teeb thiab thauj khoom tawm thiab tso tawm.
Photovoltaic siv
Ib qho nqaj ntawm lub teeb nyob rau ntawm lub semiconductor thiab nyob rau hlau los yog insulator nyob rau hauv cov nyhuv yog txawv. Raws li cov dawb electrons nyob rau hauv cov hlau ntau, thiaj li hais tias lub teeb tshwm sim los ntawm kev hloov nyob rau hauv conductivity yog tag nrho negligible. Insulators nyob rau hauv kev kub muaj peev xwm tsis tuaj yeem tsim muaj ntau dua electrons mus koom nrog kev kho mob. Thiab cov kev sib txuas ntawm cov hlau thiab lub nruab nrab ntawm lub tshuab hluav taws xob ntawm lub semiconductor ntawm lub cev ntawm electron losis tswv yim quab yuam yog ntau me dua cov insulator, pom lub teeb duab photon zog yuav zoo siab los ntawm kev sib raug zoo mus rau kev tswj tuav lub xeev, uas yog qhov hluav taws xob ntawm cov hluav taws xob. Thaum muaj ib qho hluav taws xob hauv cheeb tsam ntawm qhov chaw ntawm lub semiconductor, cov photogenerated muaj yuav nce, thiab tsis muaj qhov sib txawv ntawm cov hluav taws xob thiab cov hluav taws xob, thiab qhov hluav taws xob ntawm qhov hluav taws xob yuav raug tsim tawm ntawm ob sab ntawm hluav taws xob vim tus nqi tsub zuj zus. Qhov no yog cov nyhuv photovoltaic.
Kev faib tawm ntawm lub nruab hnub ci zog
Ua ntej, kab sib txuas nrog hnub ci zog tsim
1, ib theem-theem kab sib txuas nrog lub zog tsim system
2, 3-theem kab sib txuas nrog lub zog txuas hluav taws xob
Thib ob, hnub tim tua hluav taws xob lub cev
1, DC hnub ci zog tsim
2, hloov lub hnub ci zog tsim system
3, AC thiab DC lub hnub ci zog tsim
Qeb peb, tawm - daim phiaj ua zog hnub ci zog lub cev
Lub inverter yog lub hlwb ntawm tag nrho lub hnub ci zog tsim system, yog li nws yog ib qhov tsim nyog los xyuas kom meej tias lub tso zis hluav taws xob ntawm lub inverter ntais cov zis lub zog ntawm lub square matrix tubntxhais. PV system Qhov tseeb inverter txhais tau hais tias nws muaj peev xwm tawm tau cov lus tseeb thiab tus nqi rau cov neeg siv khoom kawg.
Yam tsawg kawg koj yuav tsum muaj peev xwm pom lub hwj chim thiab lub zog ntawm qhov inverter. Qee cov tib neeg kuj xav pom qhov muaj nuj nqis thiab cov nqi tam sim no, thiab yog tias koj yog tus neeg zoo li no, peb tuaj yeem nruab ib txoj kev tswj xyuas ntau zog rau koj. Yog tias koj tsis paub dab tsi txog kev khiav haujlwm hauv cov txheej txheem, nws tsis yooj yim los xyuas kom meej tias lub kaw lus yuav ua kom zoo. Qhov kev sib txuas lus ncaj nraim hauv lub tsev hnub ci zog lub cev yuav tsum vam khom lub txiaj ntsim ntawm qhov hluav taws xob vim nws cov inverter yuav tsum tau ua raws li cov thawj coj ntawm kab sib chaws thiab, yog tias qhov hluav taws xob ntau tshaj li qhov tau txais kev txwv, nws yuav tsum tawm hauv net.
Ua ke nrog cov kab sib chaws, lub tshuab nrog lub roj teeb muaj me ntsis yooj, tab sis daim phiaj no tseem ceeb heev rau nws.
Rau DC solar zog system thiab cov pej xeem muaj zog daim phiaj thiab teeb meem voltage, vim hais tias inverter yuav tsum coj "mloog lus" tus cwj pwm, yog li nws yog ib qho tseem ceeb rau ob qho tib si photovoltaic zog generation systems. Inverter sab ntawm sab nraum lub qhov rais, piv nrog DC sab ntau me, thiab hauv kev xav txog kev ruaj ntseg, pauv sab yog tsis kho. Rau tag nrho cov kev sib tham sib ntawm inverters, qhov siab dav npaum li cas yog cov nominal kab voltage -12% - + 10%.
