Nrog rau kev nce qib sai ntawm cov thev naus laus zis hluav taws xob rov ua dua tshiab, cov photovoltaic (PV) hauv tsev thiab cov tshuab khaws cia hluav taws xob tau dhau los ua qhov kev daws teeb meem nrov dua rau cov tswv tsev villa thiab cov tsev sib cais. Los ntawm kev sib txuas cov hluav taws xob hnub ci nrog kev khaws cia roj teeb, cov tshuab no pab txo kev siv hluav taws xob ntawm lub network, ua kom cov nqi hluav taws xob zoo dua, thiab muab hluav taws xob thaub qab thaum lub network tsis ua haujlwm - txhim kho kev ywj pheej ntawm lub zog thiab kev nyob zoo.
Hauv cov tsev nyob PV thiab cov chaw khaws cia, kev saib xyuas lub zog kom raug yog lub luag haujlwm tseem ceeb. Lub ntsuas hluav taws xob tsis yog tsuas yog lub cuab yeej them nqi xwb - nws cuam tshuam ncaj qha rau kev nyab xeeb ntawm lub kaw lus, kev ua haujlwm zoo, thiab kev ua haujlwm ntawm kev tswj hwm kev xa tawm. Yog li ntawd, kev xaiv cov kev daws teeb meem ntsuas hluav taws xob kom raug yog qhov tseem ceeb rau kev ua haujlwm ruaj khov thiab ua raws li txoj cai.
1. Kev Ntsuas Zog Hauv Cov Tsev Nyob PV thiab Cov Tshuab Cia Khoom
1.1 Kev daws teeb meem rau cov tsev loj thiab cov tsev sib cais
Feem ntau cov tshuab PV thiab cov tshuab cia khoom hauv tsev yog tsim los rau cov tsev neeg ib leeg lossis cov tsev so, qhov twg lub peev xwm ntawm lub tshuab muaj ntau thiab kev ruaj khov mus sij hawm ntev yog qhov tseem ceeb. Cov tshuab no feem ntau ua lub hauv paus ntawm kev tswj hwm lub zog hauv tsev neeg, sib npaug ntawm kev siv tus kheej thiab kev tswj hwm tus nqi hluav taws xob.
Hauv cov chaw ib puag ncig villa ib txwm muaj,WiFi ntse ntsuas zogFeem ntau yog qhov kev xaiv uas siv tau thiab ua tau zoo. Cov tsev so feem ntau muaj cov qauv hluav taws xob yooj yim, ua rau nws yooj yim los npaj cov chaw teeb tsa rau cov ntsuas hluav taws xob thiab cov inverters tiv thaiv kev xa tawm. Tib lub sijhawm, kev pabcuam WiFi ruaj khov tso cai rau kev sib txuas lus txhim khu kev qha rau kev saib xyuas lub zog tiag tiag thiab cov haujlwm tswj hwm lub zog yooj yim.
Rau kev teeb tsa qhov twg WiFi tsis muaj zog lossis tsis muaj - thiab qhov twg cov neeg siv nyiam zam tus nqi siab dua thiab qhov nyuaj ntawm RS485 wiring - point-to-point wireless transmission solutions tuaj yeem yog lwm txoj hauv kev. Hauv qee lub khw txawv teb chaws xws li Tebchaws Europe thiab Australia, cov thev naus laus zis wireless ntev-qis zog twb tau siv los txhawb kev sib txuas lus ruaj khov ntawm cov meters thiab cov txheej txheem tswj hluav taws xob.
1.2 Cov Ntsuas Zog Ntse nrog Cov Hloov Hluav Taws Xob Sab Nraud
Cov ntsuas hluav taws xob ntse uas tsim los rau cov tsev nyob PV, cov micro-inverter systems, cov roj teeb cia khoom, thiab cov kev daws teeb meem hluav taws xob AC-coupled feem ntau siv cov transformers tam sim no sab nraud (CTs). Qhov kev tsim no tso cai rau kev teeb tsa yooj ywm thiab kev ntsuas qhov tseeb thaum ua kom lub cuab yeej me me thiab yooj yim rau kev teeb tsa.
Cov 'meter' no muaj peev xwm saib xyuas cov yam ntxwv hluav taws xob tseem ceeb, xws li lub zog, qhov hluav taws xob, tam sim no, thiab kev siv hluav taws xob. Nrog kev txhawb nqa rau cov txheej txheem sib txuas lus xws li Modbus TCP lossis HTTP, lawv tuaj yeem txuas nrog cov inverters lossis cov txheej txheem tswj hluav taws xob (EMS) ntawm WiFi lossis lwm yam thev naus laus zis wireless.
Lub ntsuas hluav taws xob ob txoj kevtxhawb nqa cov haujlwm tseem ceeb xws li kev tswj hwm kev xa tawm, kev tswj hwm PV, thiab kev tswj hwm roj teeb / kev tso tawm - ua rau lawv zoo rau cov kab ke hnub ci hauv tsev faib tawm.
2. Kev Xav Txog Kev Teeb Tsa thiab Kev Txuas Hluav Taws Xob
Kev teeb tsa kom zoo yog qhov tseem ceeb heev rau kev ntsuas qhov tseeb thiab kev nyab xeeb ntawm lub kaw lus. Thaum teeb tsa lub ntsuas hluav taws xob ntse hauv lub tsev PV thiab lub kaw lus cia khoom, yuav tsum ua raws li cov ntsiab cai dav dav hauv qab no:
-
Cov txheej txheem ib theem feem ntau xav tau kev sib txuas rau ib theem xwb
-
Cov transformers tam sim no yuav tsum tau teeb tsa raws li qhov system configuration thiab theem xav tau
-
Cov voj voog hluav taws xob nkag mus yuav tsum tau tiv thaiv los ntawm cov fuses ntsuas kom raug kom ntseeg tau tias muaj kev nyab xeeb hluav taws xob
-
Txhua txoj haujlwm txuas hluav taws xob yuav tsum tau ua thaum lub zog raug txiav tawm tag nrho
-
Yuav tsum tau txheeb xyuas qhov kev taw qhia CT thiab kev sib phim theem kom tsis txhob muaj qhov yuam kev ntsuas
Kev ua raws li cov qauv kev teeb tsa pab ua kom ntseeg tau tias lub kaw lus muaj kev ntseeg siab mus sij hawm ntev thiab kev sau cov ntaub ntawv hluav taws xob raug.
3. Cov Txiaj Ntsig Tseem Ceeb ntawm Cov Ntsuas Hluav Taws Xob Tiv Thaiv Kev Xa Khoom Tawm
Cov ntsuas hluav taws xob niaj hnub siv rau hauv cov ntawv thov PV hauv tsev muaj ntau qhov zoo ntawm kev siv tshuab:
Tsim Kom Me Me Thiab Yooj Yim
Kev teeb tsa DIN-rail nrog lub cev me me ua rau muaj kev teeb tsa yooj yim hauv cov laug cam faib khoom. Lub platform ntsuas tib yam tuaj yeem txhawb nqa ib theem lossis peb theem daim ntawv thov, hloov kho rau ntau yam kev teeb tsa ntawm lub tsev villa.
Kev Sib Txuas Lus Wireless Txhim Khu Kev
Kev txhawb nqa WiFi thiab lwm yam kev sib txuas lus wireless ua kom muaj kev sib kis cov ntaub ntawv ruaj khov hauv ntau qhov chaw nyob.
Kev Tsim Hluav Taws Xob Uas Yooj Yim Rau Cov Neeg Teeb Tsa
Cov qhov hluav taws xob ntsaws thiab cov txheej txheem txuas hluav taws xob yooj yim txo lub sijhawm teeb tsa thiab txo qhov kev pheej hmoo ntawm kev ua yuam kev ntawm cov xov hlau, ua rau kev xa tawm ntawm qhov chaw ua haujlwm zoo dua.
Kev Tshawb Fawb Txog Kev Txuas Hluav Taws Xob
Cov haujlwm kuaj mob uas ua tiav lawm tuaj yeem nrhiav tau cov xwm txheej tsis zoo ntawm cov xov hlau. Thaum ua haujlwm ua ke nrog cov inverters, lub kaw lus tuaj yeem txheeb xyuas cov teeb meem CT, cov theem tsis sib xws, lossis cov kev taw qhia tam sim no kom tswj tau qhov ntsuas kom raug.
Tus Nqi Hloov Kho Cov Ntaub Ntawv Ceev
Nrog rau kev hloov kho cov kev ntsuas sai sai, lub 'meter' muab cov ntaub ntawv zog ze li ntawm lub sijhawm tiag tiag, ua rau muaj kev tswj hwm lub kaw lus teb tau zoo thiab kev tswj hwm lub zog zoo tshaj plaws.
Kev Ua Raws Cai Thoob Ntiaj Teb
Tsim los ua kom tau raws li cov kev cai thoob ntiaj teb thiab kev ua raws li txoj cai, cov 'meter' no tsim nyog rau kev siv rau hauv cov haujlwm hluav taws xob rov ua dua tshiab hauv ntau thaj chaw.
Xaus lus
Hauv cov tsev niaj hnub PV thiab cov tshuab khaws cia hluav taws xob, cov ntsuas hluav taws xob ntse tau hloov zuj zus los ntawm cov khoom siv ntsuas yooj yim mus rau hauv cov khoom tseem ceeb ntawm kev tswj hwm hluav taws xob hauv tsev. Los ntawm kev sau cov ntaub ntawv hluav taws xob tas li thiab txhawb nqa cov tswv yim tswj hwm ntse, lawv txhim kho kev nyab xeeb ntawm lub kaw lus, kev ua haujlwm zoo, thiab kev ua haujlwm zoo.
Thaum cov thev naus laus zis ntsuas lub zog txuas ntxiv mus koom ua ke nrog IoT platforms thiab cov kev daws teeb meem kev tswj hwm lub zog ntse, cov 'meter' no yuav ua lub luag haujlwm loj dua hauv kev ua kom muaj kev kwv yees lub zog tsim hluav taws xob raug, kev teem sijhawm cia khoom yooj ywm, thiab kev siv hluav taws xob tsawg dua. Rau cov tswv tsev villa thiab cov neeg koom ua ke uas tsom mus rau qhov zoo, kev ntseeg siab, thiab kev ruaj khov, kev xaiv lub 'meter' ntse yog ib kauj ruam tseem ceeb rau kev tsim kom muaj lub ecosystem hluav taws xob hauv tsev ntse tiag tiag.
