Chii chinonzi photovoltaic energy storage system?
Sisitimu yekuchengetedza simba remagetsi inochinja simba rezuva kuita simba remagetsi kuti ripe midziyo yemumba ukuwo richichengeta rakawandisa kuti rishandiswe husiku kana pasina simba remagetsi.
Chii ichi uye ndezvipi zvikamu zvikuru?
1. Photovoltaic module: ine ma photovoltaic modules akati wandei (anozivikanwawo se solar panels) ayo anobata chiedza chezuva uye achichishandura kuita direct current.
2. Kurongedza, zvishongedzo uye tambo: zvinoshandiswa kugadzirisa ma solar panels uye kutakura simba reDC rinogadzirwa kuenda ku inverter.
3. MaInverter (akabatana negrid uye asiri pagrid): Simba remagetsi rinochinjana (AC) rinogadzirwa nekupinza simba remagetsi rakananga (DC) rinogadzirwa nema solar panels, uye rinochengeta simba rakawandisa musystem yekuchengetera simba, iyo inogonawo kubatanidzwa ne city grid.
4. Midziyo yekuchengetedza simba: Kazhinji zvinoreva mabhatiri, akadai semabhatiri e-lithium nedzimwe mhando dzemabhatiri, anochengetedza magetsi anogadzirwa nesimba rezuva asingashandiswe nekukurumidza kuburikidza ne-inverter kuti azoshandiswa gare gare.
5. EMS neBMS: EMS ndiyo sisitimu inotarisa nekutarisira mashandiro esisitimu yese kuona kuti zvikamu zvese zvinoshanda zvakanaka uye zvakachengeteka. BMS ndiyo sisitimu yekutarisira bhatiri rekuchengetera, inogadzirisa nekudzora kuchaja nekuburitsa bhatiri.
6. Bhokisi rekubatanidza: rinosanganisira marudzi ese emidziyo yekudzivirira nemaswichi, zvakaita sekudzivirira kukwira kwemagetsi (kudzivirira mheni) pakati pe solar access inverter, ma fuse, ma DC circuit breakers, ma utility input circuit breakers, ma uninterruptible power supply output circuit breakers nezvimwewo.
Mhedzisiro ye photovoltaic, nzira yekuwana magetsi kubva kusimba rezuva
1. Kutorwa kwemaphoton: Kana chiedza chezuva (kusanganisira mamwe masosi echiedza) chikarova zvinhu (silicon) zve solar panel, simba remaphoton rinotorwa nezvinhu zve semiconductor.
2. Kufadzwa kwemaerekitironi: Simba rephoton rinonyudzwa rinoita kuti maerekitironi ari mu semiconductor asvetuke kubva mubhandi revalence kuenda kubhandi rekufambisa, zvichichinja kubva pabhandi rebound kuenda kubhandi refree.
3. Kugadzirwa kwemaerekitironi nemaburi maviri: Kana erekitironi yapinda mubhendi rekufambisa, inosiya buri mubhendi revalence. Erekitironi neburi iri zvinoumba buri remaerekitironi nemaburi maviri.
4. Kugadzira munda wemagetsi: Nzvimbo dzemhando yeP neN dzinowanzo kuwanikwa muzvinhu zve photovoltaic, uye panosangana nzvimbo idzi mbiri (kureva, mubatanidzwa wePN), munda wemagetsi wemukati unoumbwa.
5. Kufambisa kufamba kwemaerekitironi: Simba iri remagetsi remukati rinoita kuti maerekitironi akasununguka afambe achienda kunzvimbo yerudzi rweN uye maburi afambe achienda kunzvimbo yerudzi rweP, uye kufamba uku kunogadzira magetsi.
6. Kuunganidza magetsi: Kuburikidza ne inverter, magetsi aya anoshandurwa kuita magetsi e AC kana DC uye anochengetwa musystem yekuchengetedza magetsi kuti azoshandiswa gare gare.
Mashandiro anoita ma inverter akabatana negrid neasiri grid uye mashandiro awo
1. Inverter yakabatana negrid inoshandura simba reDC rinogadzirwa nema solar panels kuita voltage yakakodzera yebhazi ye inverter kuburikidza ne MPPT module, uye yozoishandura kuita simba re AC kuburikidza nezvikamu zvemagetsi kuti ipe midziyo yemumba, uye kana paine simba rakawandisa, rinoshandurwa kuita voltage yakafanana neye system yekuchengetedza uye rinochajwa mu system yekuchengetedza kuti rive backup, uye kana paine simba rakawandisa, richadzoserwa kumashure uye richabatanidzwa mu power grid.
2. Masisitimu ekuchengetedza simba ePV ane nzira dzekuzvigadzira uye dzekuzvishandisa, nzira dzekugera nekudzikamisa ganda, uye nzira dzekuisa bhatiri pakutanga.
Kuzvigadzira uye kushandisa wega: magetsi anogadzirwa nema solar panels anoshandurwa kuita alternating current (AC) uye anoendeswa zvakananga kumidziyo yemumba, ukuwo akawandisa achichajwa musystem yekuchengetera zvinhu; kana magetsi anogadzirwa nema solar panels asina kukwana kuti ashandiswe nemidziyo yemumba, anozadzwazve uchishandisa grid yemagetsi yeguta.
Kugera Nekupinza Mupata Nekuzadzisa Mupata: Panguva yakatarwa, simba reAC kubva kugrid reguta richashandurwa kuita simba reDC uye richaiswa musystem yekuchengetera simba; panguva yakatarwa yakatarwa, simba reDC riri musystem yekuchengetera simba richashandurwa kuita simba reAC kuti ripiwe kumidziyo yemumba; kana simba rebhatiri risina kukwana, richawedzerwa negrid reguta.
Nzira Yekutanga Bhatiri: Pasinei nemamiriro ezvinhu, tanga waona kuti simba resisitimu yekuchengetedza simba razara, kana simba rezuva rabuda, richashandurwa kuita simba reAC rekushandisa bhatiri repamba, uye kana basa rekubatanidza grid ravhurwa, mari yakawandisa ichawedzerwa kugrid reguta.
Maitiro ekugadzira uye kuverenga kuti mangani maW solar panels ekuisa
Panera rezuva: LESSO 550W
Saizi: L 2278 x 1134mm inenge 2.6 sq. ft.
Kurema: 28kg
Simba: 550W
Fomura yekuverenga nzvimbo:
Cherechedza: Tsigira ma solar panels ari pasi pe7KW
Simba rose re solar panel: 550W*12=6.6KW
Nzvimbo yedenga inodiwa: 12 x 2.6 sq. ft. = 31.2 sq. ft.
Kuverenga kwemagetsi ezuva nezuva:
Semuenzaniso, Wenzhou, China, zuva rinopenya maawa 3.77, pa watt pagore kugadzirwa kwemagetsi 1.088KWH, kushandiswa kwemaawa pagore nemazvo maawa 1087.08. Kona yekuisa: 18 degrees
Kugadzirwa kwemagetsi kwezuva nezuva = 6.6KW x 3.77H = 24.88KWH
Kugadzirwa kwemagetsi pagore = 6.6KW x 1087.08H = 7174.728KWH
