Anti-Reverse Power Flow Detection: Vim Li Cas Nws Tseem Ceeb rau Chaw Nyob Hauv Lub Zog Cia, Balcony PV, thiab C&I Zog Cia

Raws li thaj chaw hnub ci thiab lub zog cia tshuab tau nrov zuj zus, qhov kev sib tw tseem ceeb tshwm sim: rov qab fais fab ntws. Thaum pub ntau lub zog rov qab mus rau daim phiaj zoo nkauj, kev tswj tsis tau rov qab fais fab tuaj yeem ua rau muaj kev nyab xeeb loj, kev ua txhaum cai, thiab khoom siv puas tsuaj.

Reverse Power Flow yog dab tsi?

Rov qab fais fab ntws tshwm sim thaum hluav taws xob tsim los ntawm koj lub hnub ci vaj huam sib luag lossis khaws cia hauv koj lub roj teeb ntws rov qab mus rau hauv daim phiaj siv hluav taws xob. Qhov no feem ntau tshwm sim thaum:

• Koj lub hnub ci vaj huam sib luag tsim hluav taws xob ntau dua li koj lub tsev siv
• Koj lub roj teeb lub cev tau them tag nrho thiab hnub ci ntau tshaj li kev noj
• Koj tab tom tso koj lub roj teeb thaum lub sijhawm siv tsawg

Yog vim li cas Reverse Power Flow yog qhov txaus ntshai rau cov tsev nyob

Grid Safety Kev txhawj xeeb

Cov neeg ua haujlwm siv hluav taws xob cia siab tias cov kab hluav taws xob yuav raug tshem tawm thaum muaj hluav taws xob. Rov qab fais fab ntws tuaj yeem ua kom cov kab muaj zog, tsim kom muaj kev pheej hmoo hluav taws xob rau cov neeg saib xyuas.

Cov khoom puas tsuaj

Backfeed fais fab tuaj yeem ua rau puas tsuaj:

• Utility transformers thiab cov cuab yeej tiv thaiv
• Cov khoom siv hauv zej zog
• Koj tus kheej inverter thiab cov khoom siv hluav taws xob

Cov teeb meem kev cai ua raws cai

Feem ntau cov kev siv hluav taws xob txwv tsis pub muaj kev sib txuas ntawm kab sib txuas. Rov qab fais fab ntws tuaj yeem ua txhaum cov ntawv cog lus sib txuas, ua rau raug nplua lossis yuam kev kaw lus.

Qhov System Performance Impacts

Uncontrolled export tuaj yeem ua rau:

• Inverter shutdowns los yog throttling
• Txo lub zog siv tus kheej
• Nthuav hnub ci tiam

Yuav Ua Li Cas Anti-Reverse Power Flow Detection ua haujlwm

Niaj hnub nimno kev tswj hwm lub zog siv ntau txoj hauv kev los tiv thaiv kev xa tawm tsis raug cai:

Kev saib xyuas lub zog Flow

Advanced zog ntsuas zoo li peb PC311-TYbidirectional zog ntsuastsis tu ncua saib xyuas lub zog kev taw qhia thiab qhov loj ntawm daim phiaj sib txuas. Cov cuab yeej no tuaj yeem ntes tau txawm tias me me ntawm lub zog rov qab hauv vib nas this.

Inverter zog txwv

Thaum kuaj pom lub zog thim rov qab, lub kaw lus teeb liab inverters kom txo cov zis, tswj xoom xa tawm lossis txwv kev xa tawm tsis pub dhau kev tso cai siv hluav taws xob.

Roj teeb Charge Control

Lub hnub ci zog ntau dhau tuaj yeem hloov mus rau lub roj teeb cia es tsis yog xa tawm mus rau hauv daim phiaj, ua kom nws tus kheej siv ntau tshaj.

Kev daws teeb meem rau kev siv sib txawv

Balcony Fais Fab Cog (Balkonkraftwerke)

Rau plug-in solar systems, anti-reverse flow functionality yog feem ntau integrated ncaj qha mus rau hauv microinverters los yog lub hwj chim hluav taws xob Cheebtsam. Cov tshuab no feem ntau txwv cov khoom tsim tawm los tiv thaiv kev xa tawm thaum ua kom nws tus kheej siv ntau tshaj plaws.

Chaw Nyob Zog Cia Systems

Ua kom tiav cov roj teeb hauv tsev xav tau daim phiaj-forming inverters nrog kev tswj fais fab siab tshaj plaws. Cov tshuab no tuaj yeem ua haujlwm hauv xoom-export hom thaum tswj tsev fais fab zoo.

Kev Lag Luam & Kev Siv Lag Luam

Cov tshuab loj dua feem ntau siv cov tshuab hluav taws xob tshwj xeeb uas sib txuas cov nyiaj tau los-qib ntsuas nrog cov kev tswj hwm qib siab tshaj plaws los tswj hwm lub zog ntws hla ntau tiam neeg thiab cov khoom thauj.

Ua kom muaj txiaj ntsig zoo rov qab tiv thaiv hluav taws xob

Ib tug txhim khu kev qha anti-reverse hwj chim flow system yuav tsum tau:

1. Kev ntsuas fais fab tseeb
   High-precision zog ntsuas nrog bidirectional ntsuas muaj peev xwm
2. Lub Sijhawm Teb Ceev
   Kev kuaj xyuas thiab tswj cov tshuab uas teb nyob rau hauv lub voj voog hluav taws xob
3. Grid Code Ua raws cai
   Cov kab ke ua tau raws li qhov yuav tsum tau muaj kev sib tshuam hauv zos
4. Redundant Safety Systems
   Ntau txheej tiv thaiv kom ntseeg tau
