Nrog rau kev txhim kho tas mus li thiab kev siv lub zog tauj dua tshiab, qhov kev thov rau lub zog cia tshuab hauv kev lag luam thiab kev lag luam tseem nce ntxiv. Lub zog cia cov tshuab tuaj yeem sib npaug ntawm cov khoom siv hluav taws xob thiab kev xav tau, txhim kho kev siv hluav taws xob zoo, txo cov nqi hluav taws xob rau cov lag luam, thiab muab kev txhawb zog ruaj khov thiab txhim khu kev qha rau cov neeg siv khoom lag luam thiab kev lag luam. Kab lus no yuav txheeb xyuas cov txheej txheem tsim ntawm lub zog cia qhov system daim phiaj sib txuas raws li qhov tseeb qhov project.
1. Cov ntsiab lus ntawm Scheme Design
Kev tsim qauv ntawm kev lag luam thiab kev lag luam lub zog cia khoom yog ib kauj ruam tseem ceeb hauv kev siv lub zog cia cov dej num, nrog rau qhov tseem ceeb ntawm kev ua kom muaj kev nyab xeeb, ruaj khov, thiab kev ua haujlwm ntawm lub cev. Lub hauv paus ntsiab lus tsim qauv yog raws li nram no:
01
Txiav txim siab qhov muaj peev xwm nkag tau ntawm lub zog khaws cia
Ua ntej, nws yog ib qho tsim nyog yuav tsum tau ua kom tiav lub zog xav tau kev txheeb xyuas ntawm lub tuam txhab, nkag siab cov ntaub ntawv tseem ceeb xws li qhov teeb meem ntawm kev hloov pauv, cov yam ntxwv ntawm kev siv hluav taws xob, kev thauj khoom nkhaus, thiab qhov sib txawv ntawm tus nqi siab siab, txhawm rau txiav txim siab qhov tsim nyog lub zog cia thiab tso zis hluav taws xob. . Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum xav txog qhov scalability ntawm lub system thiab cia qhov chaw rau yav tom ntej expansion. Hauv cov txheej txheem kev npaj, peb kuj yuav tsum xav txog kev lag luam ntawm lub kaw lus, los ntawm kev teeb tsa lub zog tsim nyog, siv zog ua kom tau raws li cov neeg siv khoom xav tau thaum txo cov peev txheej thiab cov nqi kho.
02
Kev sib koom tes thiab kev koom tes ntawm lub zog khaws cia thiab daim phiaj hluav taws xob lossis lwm qhov chaw siv hluav taws xob
Lub zog cia cov tshuab tuaj yeem ua lub zog ntxiv rau daim phiaj hluav taws xob thiab ua haujlwm ntawm nws tus kheej, muab kev txhawb zog thaum xav tau. Nws kuj tseem tuaj yeem ua ke thiab txuas nrog photovoltaic, cua zog, thiab lwm yam. Yog li ntawd, hauv kev tsim cov kev sib txuas, peb yuav tsum xav txog yam xws li qib voltage thiab muaj peev xwm ntawm daim phiaj hluav taws xob lossis photovoltaic, kom ntseeg tau tias lub zog khaws cia. muaj peev xwm seamlessly integrate nrog ntau lub zog qhov chaw thiab ua tiav bidirectional ntws ntawm lub zog.
03
Tsim kev ruaj ntseg
Kev tsim kev nyab xeeb ntawm kev lag luam thiab kev lag luam lub zog cia khoom suav nrog kev nyab xeeb hluav taws xob, kev nyab xeeb hluav taws, kev tiv thaiv hluav taws xob, thiab lwm yam. Hauv kev tsim kev nkag mus, peb yuav tsum xaiv cov khoom siv hluav taws xob tsim nyog, tsim cov qauv hluav taws xob tsim nyog, thiab teeb tsa kev tiv thaiv zoo los xyuas kom muaj kev nyab xeeb ntawm kev ua haujlwm. Nyob rau tib lub sijhawm, peb kuj yuav tsum tau ua cov kev kuaj xyuas kev nyab xeeb thiab kev saib xyuas tsis tu ncua kom paub meej thiab daws cov kev pheej hmoo ntawm kev nyab xeeb.

Tswj lub tswv yim tsim
Lub zog cia tshuab koom nrog ntau qhov kev thov hauv kev ua haujlwm tiag tiag, thiab kev tswj xyuas cov tswv yim tsim yog ib feem tseem ceeb ntawm lub zog cia tshuab hauv kev ua haujlwm tiag tiag, txhawm rau txhim kho kev ua haujlwm, kev ruaj ntseg, thiab kev ntseeg tau. Piv txwv li, siab / tsis tshua muaj siab sab tiv thaiv rov qab, xav tau kev tswj hwm, kev tswj hwm kev tswj hwm ntawm photovoltaic cia, ncov hav arbitrage, muaj peev xwm nthuav dav, thiab lwm yam.
Los ntawm kev txhim kho cov cuab yeej saib xyuas ntse thiab txuas mus rau EMS tswj qhov system, qhov tseem ceeb tsis xws li kev ua haujlwm, cov ntaub ntawv hluav taws xob, thiab cov ntaub ntawv kub ntawm lub zog khaws cia tuaj yeem saib xyuas lub sijhawm. Los ntawm kev txheeb xyuas cov ntaub ntawv, lub kaw lus lub tswv yim ua haujlwm tuaj yeem ua kom zoo dua los txhim kho nws cov txiaj ntsig. Tsis tas li ntawd, kev saib xyuas tej thaj chaw deb thiab kev teem caij ntawm lub zog cia cov tshuab tuaj yeem ua tiav los ntawm cov chaw taws teeb tswj, kev txhim kho qib kev tswj hwm thiab cov lus teb ceev ntawm qhov system.
2. Tsim Case Analysis
Noj 500KW / 1045KWh lub zog khaws cia ua piv txwv, qhov hloov pauv uas twb muaj lawm hauv lub tiaj ua si yog 1600KVA. Qhov siab tshaj plaws load ntawm lub tiaj ua si thoob plaws hauv lub xyoo yog nyob ib ncig ntawm 900KW, thiab qhov tsawg kawg nkaus load yog nyob ib ncig ntawm 400KW. Lub peev xwm nruab photovoltaic yog 330KW, thiab peb npaj yuav ntxiv 500KW / 1045KWh lub zog cia.
01
Kev xaiv qhov chaw rau qhov chaw ruaj ntseg ntawm lub zog
Kev xaiv ntawm qhov chaw rau lub zog cia installation yog ib kauj ruam tseem ceeb hauv kev tshawb fawb ua ntej ntawm qhov project, uas yuav tsum muaj kev xav txog ntau yam. Ua ntej, qhov tseem ceeb ntawm cov nyiaj tau los rau lub zog cia yog los ntawm qhov sib txawv ntawm tus nqi siab tshaj plaws. Nws yuav tsum tau txuas nrog transformers nrog hnyav loads los yog siab volatility nyob rau hauv lub tiaj ua si kom ua kom lub ncov shaving thiab hav filling nyhuv ntawm lub zog cia system. Nws yog feem ntau pom zoo kom nruab ze ntawm chav faib hluav taws xob kom txuag tau tus nqi ntawm kev sib txuas cables.
Qhov thib ob, qhov chaw xaiv yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm geological thiab climatic tej yam kev mob. Ib lub zog cia txee feem ntau hnyav tshaj 2.5 tons, thiab cov cuab yeej muaj qee qhov kev xav tau rau kev ruaj ntseg ntawm lub hauv paus thiab kev nyab xeeb. Thaum xaiv ib qhov chaw, nws yog ib qho tsim nyog yuav tsum zam cov cheeb tsam uas tsis ruaj tsis khov geological tej yam kev mob, nquag muaj kev puas tsuaj ntuj tsim, dej nyab, nrog rau cov chaw uas muaj hluav taws kub tawm thiab cov neeg ua haujlwm tuab.
