Hybrid inverters muab lub hnub ci thiab roj teeb inverter ua ke hauv ib chav tsev, ua kom DC lub zog tsim los ntawm hnub ci (los yog cua) hloov mus rau AC ncaj qha, lossis xa mus rau lub roj teeb rau kev cia, ua ntej hloov mus rau AC. Tsis zoo li tus qauv 'ib txoj kev' (DC rau AC) inverters, hybrid inverters ua haujlwm 'ob qho tib si', ua kom AC hluav taws xob coj los ntawm daim phiaj lossis lub tshuab hluav taws xob, hloov mus rau DC thiab khaws cia rau hauv lub roj teeb.

 

 

 

Koj tseem tuaj yeem ntxiv roj teeb cia rau lub kaw lus tsim nrog lwm hom inverter xws li tus qauv 'txoj hlua' inverter. Txawm li cas los xij, lub roj teeb yuav yog AC txuas nrog raws li hauv cov qauv hauv qab no, txhais tau hais tias lub zog dhau los ntawm lub hnub ci vaj huam sib luag yuav hloov los ntawm DC mus rau AC thiab rov qab mus rau AC dua kom khaws cia rau hauv lub roj teeb.

 

 

AC coupling nce AC rau DC kev hloov pauv poob thiab tsis zoo li DC coupling. Nws yuav zoo dua khaws cov hnub ci ntau dhau hauv lub roj teeb ua ntej hloov ntawm DC mus rau AC, raws li hauv schematic saum toj no. Siv lub hybrid inverter kuj txhais tau hais tias tsuas yog ib qho inverter yuav tsum muaj rau lub roj teeb ua ke thiab lub hnub ci. Koj tuaj yeem nruab lub hnub ci yam tsis muaj kev cia khoom siv lub tshuab hluav taws xob hybrid, thiab tom qab ntawd ntxiv kev cia rau hnub tom qab.

Feem ntau cov roj teeb cia hauv qhov tseeb AC txuas nrog, suav nrog Tesla Powerwall 2 nrov heev. AC coupling ua rau kev txiav txim siab thaum rov kho lub roj teeb rau lub hnub ci uas twb muaj lawm uas twb muaj hnub ci inverter nyob rau hauv qhov chaw. Txawm li cas los xij nrog cov khoom tsim tshiab lossis lub hnub ci tshiab tau teeb tsa nrog kev cia, hybrid inverter ua rau muaj kev nkag siab ntau dua.

 

Central inverters

 

Central inverter units pib los ntawm ib ncig ntawm 100kW nyob rau hauv loj thiab yog li tsis muaj feem xyuam rau domestic los yog me me kev lag luam systems. Lawv tuaj yeem loj li 4MW thiab lawv feem ntau siv rau cov hnub ci loj loj rau 'centralise' fais fab rau hauv ib qho chaw. Cov hlua sib txuas yog siv los ua ke cov hlua sib txuas ntawm cov vaj huam sib luag; cov no yog ces recombined rau pub rau hauv nruab nrab inverter. Lwm txoj hauv kev yog siv ntau cov hlua me me inverters, tsim kom muaj 'distributed architecture'.

Ntawm qhov loj me, nruab nrab inverters muab cov kev daws teeb meem tsawg dua li cov hlua inverters vim tias tsawg dua inverters yuav tsum tau ib qhov chaw. Piv txwv li, 20 MW hnub ci ua liaj ua teb tuaj yeem siv tsib mus rau 10 lub hauv paus inverters nrog rau cov thawv sib txuas, lossis nws tuaj yeem siv ntau pua txoj hlua inverters. Qhov no yog qhov laj thawj tseem ceeb rau kev siv central inverters. Txoj hlua inverters feem ntau muab ntau lub zog ua kom zoo dua qub (vim qhov Tshaj Lij Tshaj Lij Tshaj Tawm Tshaj Tawm). Tsis tas li ntawd, lawv muaj qhov zoo dua yog tias ib txoj hlua lossis inverter tsis ua haujlwm, tsuas yog ib feem me me ntawm lub hnub ci ua liaj ua teb lub zog poob. Nrog central inverters, ntau lub zog yuav poob yog tias ib qho inverter poob. Tsis tas li ntawd, kev daws teeb meem thiab / lossis kho lub hauv paus inverter yog ib txoj haujlwm tshwj xeeb tshaj li kev daws teeb meem thiab / lossis kho cov hlua inverter. Nws kuj tseem pheej yig dua los tuav cov khoom seem ntawm cov hlua inverter dua li nws yog los tuav lub hauv nruab nrab inverter.

Nyob rau hauv UK, rau me me hnub ci ua liaj ua teb (txog 5MW), txoj hlua inverters yuav nyiam.

 

 

Kev ua haujlwm siab automated

 

Tom qab hnub tuaj, sai li sai tau muaj cov zis txaus tsim los ntawm hnub ci modules, chav tswj hwm pib saib xyuas cov kab hluav taws xob hluav taws xob thiab zaus nrog rau lub zog muaj nyob hauv cov vaj huam sib luag. Thaum lub hnub ci txaus tau txais, lub hnub ci inverter pib pub rau cov khoom siv hluav taws xob sib kis. Nyob ntawm seb hom kev teeb tsa, ob peb watts ntawm lub hnub ci zog yuav txaus ua txoj haujlwm!

Lub inverter yuav tam sim no txuas ntxiv ua haujlwm xws li nws ib txwm rub lub siab tshaj plaws ntawm lub zog los ntawm lub hnub ci modules. Qhov kev ua haujlwm no hu ua MPPT (Maximum Power Point Tracking) thiab ua tiav nrog tus nqi ntawm ntau dua 99 feem pua! Tom qab tsaus ntuj, thaum lub zog muab tsis txaus los pub cov khoom siv hluav taws xob sib kis, lub inverter txiav txiav qhov kev sib txuas rau daim phiaj thiab tsis ua haujlwm, tau kawg nrog txhua qhov chaw thiab cov ntaub ntawv khaws cia.

Daim phiaj saib xyuas, kev nyab xeeb txiav tawm

Inverters yuav tsum ua kom tau raws li cov qauv kev nyab xeeb yam tsawg kawg nkaus thiab ua raws li kev lag luam tus qauv kev tiv thaiv chaw. Qhov no txhais tau hais tias lawv yuav tsum tau saib xyuas qhov voltage thiab zaus thiab nres kev khiav hauj lwm hauv qhov xwm txheej tsis xwm yeem (xws li kev siv hluav taws xob, kev cuam tshuam). Yog tias ib qho kev tiv thaiv tau ua txhaum cai lawv nres qhov pub rau hauv daim phiaj. Qhov no yog qhov tseem ceeb. Nyob rau hauv qhov kev tshwm sim ntawm lub hwj chim txiav engineers yuav ua hauj lwm nyob rau hauv cov hluav taws xob kis tau tus mob kab mus nrhiav qhov txhaum. Pom tseeb tias lawv tsis tuaj yeem ua qhov no yog tias koj lub cev tseem siv hluav taws xob rau hauv daim phiaj.

Cov inverters kuj tseem muaj lub tshuab hluav taws xob ntau zaus uas ua kom muaj kev sib cais galvanic ntawm DC sab los ntawm daim phiaj siv hluav taws xob.
